CHILLER NOMENCLATURE

W G Z XXX D W

Flexible Design The Daikin WGZ water chillers are completely factory assembled, piped, wired and shipped in one piece, ready for field connection of power, water piping, and refrigerant piping on remote air or evaporative cooled condenser models. Each chiller consists of compressors, insulated brazed plate or shell-and-tube evaporator and centralized electrical control panel containing all necessary equipment protection and operating controls. Packaged units (“DW”) come complete with mounted, water-cooled condensers with integral subcooler circuits. Condenserless units (“DA”) are provided without condensers to allow for remote installation of air-cooled or evaporative condensing equipment.

The WGZ chillers come in 16 sizes between 30 and 200 nominal tons (105 and 700 kW). This small capacity increment allows a selection that can closely match the required job capacity.

Many optional features can be added to fit job requirements. Several options for power connections can match field requirements. Phase failure/reversal protection and acoustical sound blankets around each compressor are a factory-installed option.

The Compressor TechnologyWGZ chillers use rugged hermetic scroll compressors constructed with an integral cast iron frame, cast iron scrolls, coated bearings, and three oil filtration devices for each compressor. Model WGZ units use environmentally acceptable R-410A refrigerant. Each refrigerant circuit has specially designed oil and gas equalization lines to control oil migration.

The design also offers radial and axial compliance (no tip seals), a large internal volume for liquid handling, a removable suction screen, and a rotary dirt trap and oil screen. In addition, the compressor is self-compensating for wear, handles liquid and debris, and inherently yields high efficiency.

Units are available in 60-hertz with voltages from 208 to 575 volt and in 50-hertz, 400 volt.

Efficient OperationCompressors are placed in tandem or trio arrangements to allow for optimized capacity modulation. Excellent part-load efficiency is obtained by operating one compressor on a tandem compressor circuit and one or two on three-compressor circuits. Each running compressor discharges to the full-sized condenser and operates at lower compression ratios with substantial power savings.

Reduced NoiseThe hermetic scroll compressors equipped on WGZ chillers are inherently quiet. Optional insulated acoustical compressor blankets will further reduce sound levels.

EvaporatorsDifferent evaporators are used depending on chiller model.

Models WGZ030D through WGZ130D: Evaporators are a compact, high efficiency, two-circuit, brazed-plate type heat exchanger consisting of parallel type 304 stainless steel plates, with a design water-side pressure of 653 psi. Each evaporator is designed and constructed according to, and listed by, Underwriters Laboratories (UL).

Models WGZ150D through WGZ200D:Evaporators are a direct-expansion, shell-and-tube type with water flowing in the baffled shell side and refrigerant flowing through the tubes. The water side working pressure is 152 psig (1048 kPa). Each evaporator is designed, constructed, inspected, and stamped according to the requirements of the ASME Boiler and Pressure Vessel Code. Double thickness insulation is available as an option.

Water-Cooled CondensersThe WGZ-DW water-cooled condensers are cleanable shell and tube type with water in the tubes and two refrigerant circuits in the shell side, divided by a vertical, midpoint partition. Each condenser circuit is capable of holding the circuit’s refrigerant charge and each circuit has its own charging and relief valves.

The condenser is constructed with a carbon steel shell and seamless integrally finned high efficiency copper tubes roller expanded into steel tubesheets. The water heads at each end have vent and drain connections and are removable.

Also included is a liquid shutoff valve, purge valve, and relief valve per ANSI/ASHRAE Pressure Vessel Code, Section VIII. Water-side working pressure is 232 psi (1599 kPa). Standard condenser connections are located on the right end looking at the control panel. Optional left hand connections available.

Air-Cooled Condensers (for WGZ-DA models)WGZ-DA chillers are designed for use with appropriately sized and configured remote air-cooled or evaporative condensers, such as Daikin Model ACH, ACL, and ACX air-cooled condensers. These condensers are available with single- or double-row, vertical discharge fans; double-row (double-circuit) are usually used with Daikin Applied chillers. Two single row (single circuit) can be used where space restrictions dictate. They are fully described and rated in the air-cooled scroll condensing unit catalog, available on www.DaikinApplied.com. They are packed with features offering tangible benefits to owners:

• Complete range of capacities from 10 to 210 tons• Circuits matched to WGZ chillers• Direct drive fan motors at 1140/830 RPM for lower sound • Patented floating tube design to eliminate tube sheet

leaks• High efficiency coil and fan motor design• Internal baffles between all fan cells• Weatherproof control panel & door-mounted disconnect

switch• G90 painted galvanized steel cabinets• Single-point power connection• Independent fusing and contactors for each fan motor• Integral pre-piped subcooler circuit

Figure 1: Daikin Applied Air-Cooled Condenser

Factory Installed Refrigerant Line ComponentsEach chiller’s refrigerant circuit has manual liquid line shutoff valve, one or two replaceable-core filter-driers (depending on size), solenoid valve, liquid line sight glass/moisture indicator, expansion valve (thermal on WGZ 030-130, electronic on WGZ 150-200) and discharge line shutoff valve. Filter-driers are replaceable-core type on all remote condenser model sizes.

The DA models for remote condenser are similarly equipped. Since there is no water-cooled condenser, a high-side pressure relief valve must be field installed in the discharge line.

The Control TechnologyThe model WGZ chiller utilizes MicroTech® II digital control electronics to proactively manage unit operation. This powerful, user-friendly control system provides the flexibility and performance needed for a stand-alone unit as well as multiple units tied into a network system.

MicroTech® II ControllerThe MicroTech® II controller’s state-of-the-art design will not only permit the chiller to run more efficiently, but will also simplify troubleshooting if a system failure occurs. The MicroTech® II controller continuously performs self-diagnostic checks, monitoring system temperatures, pressures and protection devices, and will automatically shutdown a compressor, a refrigerant circuit or the entire unit if a fault occurs. The cause of the shutdown will be retained in memory and can be easily displayed in plain language for operator review. The MicroTech® II chiller controller will also retain and display the time the fault occurred and the operating conditions that were present at the time of the fault, which is an extremely useful feature for troubleshooting. In addition to displaying alarm diagnostics, the MicroTech® II chiller controller also provides the operator with a warning of pre-alarm conditions.

Condenser Fan ControlOn remote air-cooled condenser units, the MicroTech® II controller provides control of up to four condenser fans for each of the two circuits. The control sequences condenser fans based on discharge pressure. This function may also be furnished as part of the condenser control.

Certifications and StandardsAs with many other Daikin Applied chiller products, model WGZ meets the necessary certifications and standards.

All WGZ units are constructed and/or rated with the latest ANSI/ASHRAE 15 Safety Code, National Electrical Code and ASME Boiler and Pressure Vessel Code. All models are ETL or cETL listed.

AHRI CertificationPart load performance can be presented in terms of Integrated Part Load Value (IPLV), which is defined by AHRI Standard 550/590. Based on AHRI Standard 550/590, and as shown in Figure 2, a typical chiller can operate up to 99% of the time at off-peak conditions and usually spends most of this time at less than 60% of design capacity.

Figure 2: IPLV Defined by AHRI Standard 550/590

WGZ-DW chillers are rated and certified to AHRI Standard 550/590. The ability of WGZ chillers to achieve excellent part load efficiencies, as evidenced by their IPLV ratings, is achieved by selectively cycling four or six scroll compressors. For more information on compressor functionality, see “The Compressor Technology” on page 4.

Compliance with ASHRAE Std. 90.1ASHRAE Standard 90.1 was developed to assist owners and designers make informed choices on a building’s design, systems, and equipment selection. WGZ-DW models meet or exceed ASHRAE 90.1 minimum efficiency requirements.

LEED®

Developed by the U.S. Green Building Council (USGBC) in 1998, Leadership in Energy and Environmental Design (LEED®) is an internationally recognized certification program and intends to provide building owners and operators a consistent structure for identifying and implementing practical and measurable green building design, construction, operations and maintenance solutions. For building owners who want to pursue LEED® Green Building Certification, most WGZ-D models will qualify for the Energy and Atmosphere Credit 4, Enhanced Refrigerant Management worth 2 points. Contact your local sales representative for more details.

Factory TestingExtensive quality control checks and functional tests are performed on every unit to check that each control is properly calibrated and operates correctly. Each unit is pressure tested, evacuated and charged with refrigerant prior to testing. Each unit is then rechecked for refrigerant leakage after operation. This extensive testing helps to ensure trouble-free start-ups.

Location and Space RequirementsWGZ-D units are designed for indoor application and must be located in a space where the operating and standby conditions are 40°F to 122°F (4.4°C to 50°C).

Provide clearance of 3 ft. (914 mm) on each side and end for piping and to provide space for servicing the unit. Provide sufficient clearance above the unit for component removal.

Provide clearance at either end of the unit to permit cleaning or removal of condenser tubes (see dimensional data). If a properly located door or window is provided in the wall at one end of the unit, the tubes may be able to be replaced through the opening provided.

FoundationMount the unit on a level concrete foundation. Floors must be strong enough to support the unit operating weight. If necessary, use structural supports to transfer the weight of the unit to the nearest beams.

Vibration IsolationOptional rubber-in-shear or spring vibration mounts are recommended for upper floor installations or where compressor noises might be objectionable (next to occupied spaces such as offices, meeting rooms, etc.).

Pipe vibration eliminators may be required for water piping connected to the unit to minimize transmission of water or pump noise into occupied spaces.

System Water VolumeIt is important to have adequate water volume in the system to provide an opportunity for the chiller to sense a load change, adjust to the change and stabilize. As the expected load change becomes more rapid, a greater water volume is needed. The system water volume is the total amount of water in the evaporator, air handling products and associated piping. If the water volume is too low, operational problems can occur, including rapid compressor cycling, rapid loading and unloading of compressors, erratic refrigerant flow in the chiller, improper motor cooling, shortened equipment life and other undesirable occurrences.

For normal comfort cooling applications where the cooling load changes relatively slowly, Daikin Applied recommends a minimum system volume of two to three times the flow rate (GPM). For example, if the design chiller flow rate is 120 GPM, we recommend a minimum system volume of 240 to 360 gallons.

For process applications where the cooling load can change rapidly, additional system water volume is needed. A process example would be the cooling of hot metal objects. The load would be very stable until the hot metal is dipped into the water tank. Then, the load would increase drastically.

Since there are many other factors that can influence performance, systems can successfully operate below these suggestions. However, as the water volume decreases below these values, the possibility of system instability increases.

Evaporator Variable FlowReducing evaporator flow in proportion to load can reduce system power consumption. Certain restrictions apply to the amount and rate of flow change. The rate of flow change should be a maximum of 10 percent of the change per minute. Do not reduce flow lower than the minimum flows listed in the evaporator pressure drop table: Table 25 on page 23.

Chilled Water PipingIf factory-installed flow switches are not ordered, install a flow switch in the horizontal piping of the system supply (evaporator outlet) water line.

Provide drain connections at low points in the system to permit complete drainage of the system. Locate air vents at the high points in the system to purge air out of the system. Purge air from the water system before unit start-up to ensure adequate flow through the evaporator. For WGZ models 030 to 130, the evaporators do not have vent or drain connections and they must be supplied in the field piping. For WGZ models 150 to 200, drain and vent connections are provided on the evaporator.

NOTE: Install a perforated metal basket strainer (0.062-inch perforations, 41% open area for models for WGZ 030 through 130, and a strainer with 0.125-inch perforations, 40% open area for WGZ 150 through 200) in the return chilled water line before the inlet to the evaporator.

Flush the system water piping thoroughly before making connections to the unit evaporator. Design the water piping so the chilled water circulating pump discharges into the evaporator inlet.

Install pressure gauges in the inlet and outlet water lines to the evaporator. Measure pressure drop through the evaporator to calculate proper flow. Vibration eliminators are recommended in both the supply and return water lines.

Insulate chilled water piping to reduce heat loss and prevent condensation.




Figure 3: Typical Chilled Water Piping, models WGZ030-130D (Brazed Plate Evaporator)

Figure 4: Typical Chilled Water Piping, models WGZ150-200D (Shell & Tube type Evaporator)

Condenser WaterBe certain the condenser water enters the bottom connection of the condenser and exits the condenser from the top connection. Head pressure control must be provided if the entering condenser water can fall below 60°F (15°C). Install a 20-mesh strainer in the condenser inlet line. The WGZ condenser has two refrigerant circuits with a common condenser water circuit. This arrangement makes head pressure control with discharge pressure actuated control valves difficult.

If for some reason the tower water temperature cannot be maintained at a 60°F (15°C) minimum, or when pond, lake, or well water that can fall below 60°F (15°C) is used as the condensing medium, special discharge pressure control must be used. A water recirculating system with recirculating pump, as shown in Figure 5, is recommended. This system also has the advantage of maintaining tube velocity to help prevent tube fouling. The pump should cycle with the chiller.

Ice Storage ApplicationsThe MicroTech® II controller has logic to change setpoints from the low ice-making mode to higher normal comfort cooling setpoints. It is important that the MicroTech® II controller receive a 0 VAC (normal operation) to 24 VAC (ice mode) signal to convert from ice mode to normal operating mode. MicroTech® II includes the logic to keep compressors fully loaded when operating in the ice mode. The double insulation thickness option is recommend to prevent sweating.

Two Pipe Systems When the same two pipes are used for both heating and cooling water, several limitations should be observed. The maximum allowable temperature that the evaporator should experience in a non-operating mode is 100°F (38°C). For unit operation and system changeover from heating to cooling, the maximum allowable temperature entering the evaporator is 90°F. System controls, provided by others, must prevent chiller operation until the loop temperature drops to 90°F (32°C).

Series or Parallel OperationConsider system pressure drop when designing the water piping. Parallel piped systems have half of the total system flow going through the evaporator of each chiller, reducing the individual unit and total system pressure drop for a two chiller installation.

Series piped evaporators require that the total system water flows through both evaporators. Not only is the pressure drop through each evaporator increased but the pressure drops must be added together to obtain the total evaporator pressure drop. Series piped evaporators normally require larger circulating pumps for the chilled water system.

Electrical ConnectionEvery WGZ chiller requires field installation of the main supply power plus mandatory flow switch interlock, optional pump starter auxiliary contact interlock or other field-installed devices. A control circuit transformer installed at the factory

eliminates the need for field installation of a separate 115V supply to the control circuit. However, if desired, a separate 115V field connection to the control circuit can be substituted. A system time clock and remote on-off switch can also be field installed.

See Figure 17 on page 40 (packaged units) or Figure 18 on page 41 (remote condenser models) for field control wiring diagrams. The diagrams shown represents all WGZ units; however, individual terminal numbers can vary between unit sizes. Each unit is provided with its specific wiring diagram in the control panel. All wiring must be done according to local and national codes.

Main Power Supply Disconnect SwitchEvery WGZ unit with the standard single-point power supply is equipped with compressor circuit breakers as standard. Multiple-point power connection is available as an option using two power blocks. Circuit breakers are not available with the multiple-point option.

A factory-installed, non-fused disconnect switch (required to meet NEC Code for disconnects) with a through-the-door handle is available as an option with single or multiple-point power supply. The disconnect switch(s) is properly sized for the model and voltage supplied.

A field-supplied and installed remote disconnect switch can also be used.

Control CircuitA control power transformer is standard equipment on WGZ units. Terminals are provided in the unit control center (terminals TB1 and TB1-20) for field connection to a remote 115V power supply if desired.

Terminals are also provided for field connection of the chilled water flow switch, unit time clock, ambient thermostat and/or remote on/off switch.

Condenser Pump InterlockThe condenser water pump should be interlocked to cycle with the compressor(s). This will prevent the refrigerant pressure from being overly depressed during the off cycle and allows the energy savings of pump shutdown. Interlock terminals are provided in the unit control panel.

Remote Condenser Refrigerant PipingRemote condensers are usually air cooled or evaporative. Careful design of refrigerant piping is necessary for proper system operation. The refrigerant piping should be designed to accomplish the following:

• Assure proper refrigerant feed to the evaporator.• Provide practical and economical refrigerant line sizes

without excess pressure drop.• Maintain uniform oil return to the compressor under all

load conditions.• Refer to the latest version of the ASHRAE Handbook for

recommended piping practice.Limit the length of refrigerant piping by locating the condenser as close to the chiller as possible. Avoid all unnecessary changes in direction or elevation. Two separate condensers (one for each circuit) can be selected or a single two-row condenser with the standard two-circuit manifold. The circuits must not be combined and precautions must be taken during installation to avoid cross-connecting the circuits.

CAUTIONDo not run refrigerant piping underground.

Liquid LineWhere there is a vertical lift from the condenser to the chiller, adequate subcooling must be provided to prevent liquid flashing before the expansion valve. A shutoff valve should be installed in the liquid line to allow isolation of the remote condenser.

Discharge LineThe discharge line should be trapped at the compressor and looped at the condenser (inverted trap) to prevent liquid refrigerant from draining back to the compressor. Pressure drop should be held at a minimum. Install a discharge check valve in the discharge piping in a horizontal run, close to the condenser.

Recommended Line SizingThe following tables can be used for initial line sizing. Final design should be based on ASHRAE design practice. See the WGZ-D Installation and Maintenance Manual, which can be found at www.DaikinApplied.com, for additional piping information.

Packaged Chillers (Models WGZ-DW)1. Ratings are based and certified in accordance with AHRI

Standard 550/590.

2. Performance ratings, beginning on page 18, can be interpolated for any chiller water temperature between 40°F and 50°F (4.4°C and 10.0°C) but cannot be extrapolated.

3. Chilled water quantities: ratings are based on a 10°F (5.6°C) chilled water range (2.4 gpm/ton) and can be used for a Delta-T range of 6 to 16°F (3.3 to 8.8°C) by applying performance adjustments from Table 16. The maximum/nominal/minimum flow rates and pressure drops are shown beginning on page 22. The maximum flow rate and pressure drop are based on a 6-degree chilled water temperature drop. Avoid higher flow rates with resulting lower temperature drops to prevent potential control problems resulting from very small control bands and limited start up/shut off temperature changes. The minimum flow and pressure drop is based on a full load evaporator temperature drop of 16-degrees required to maintain turbulent flow. These minimum flow rates assume that flow will be reduced proportionally to the cooling load.

4. Ratings are based on 0.0001 fouling factor for the evaporator. For other fouling factors, multiply ratings by evaporator factors from Table 16. For applications using a glycol solution, see Table 14 or Table 15 corrections.

5. Ratings are based on condenser flow of 3 gpm/ton (10°F, 5.6°C) delta-T and 0.00025 fouling factor. Corrections for other conditions are in Table 17.

Performance Adjustment FactorsAltitude Correction FactorsPerformance tables are based at sea level. Elevations other than sea level affect the performance of the unit. The decreased air density will reduce condenser capacity consequently reducing the unit’s performance. For performance at elevations other than sea level refer to Table 13.

Table 13: Altitude Correction Factors

Ethylene & Propylene Glycol FactorsWGZ units are designed to operate with a leaving chilled fluid temperature from 15°F (-9.4°C) to 60°F (16°C). Leaving chilled fluid temperatures below 40°F (4.6°C) result in suction temperatures at or below the freezing point of water and a glycol anti-freeze solution is required. The use of glycol in the evaporator will reduce the performance of the unit. The reduction in performance depends upon the glycol

concentration and temperature. This should be taken into consideration during initial system design.

Daikin Applied encourages a minimum concentration of 25% be provided on all glycol applications. Glycol concentrations below 25% are too diluted for long-term corrosion protection of ferrous metals and corrosion inhibitors need to be recalculated and possibly added to the system. Glycol in the condenser will have a negligible effect on performance because glycol at these higher temperatures will perform with characteristics similar to water.NOTE: Ethylene and propylene glycol ratings are outside the

scope of AHRI Standard 550/590-2003 certification program.

Table 14: Ethylene Glycol Correction Factors

Table 15: Propylene Glycol Correction Factors

Fouling FactorPerformance tables are based on water with a fouling factor of 0.0001 ft² x hr x °F/BTU (0.0176 m² x C/kW) in the evaporator and 0.00025 ft² x hr x °F/BTU (0.044 m² x C/kW) in water-cooled condensers according to ARI 550/590. As fouling is increased, performance decreases. See Table 16 and Table 17 for performance with other fouling factors.

For optimum unit operation, proper water treatment must be maintained. Scaling and dirt in a system will vary significantly depending on local water conditions. Water treatment should be based on characteristics of the area’s water. Improper or untreated water can lead to scale buildup, erosion and corrosion in both the condenser and evaporator.

Table 17: Condenser Fouling Factors

Evaporator and Condenser Delta-T FactorsPerformance tables are based on a 10°F (5°C) temperature difference through the evaporator and condenser. A temperature difference other than 10°F (5°C) will result in unit performance being different from what is shown. Adjustment factors for applications having temperature drops between 6°F and 16°F (3.3°C to 8.9°C) can be found in Table 18 and Table 19.

Table 18: Evaporator Delta-T Adjustment Factors

Table 19: Condenser Delta-T Adjustment Factors

Selection ProcedureKnowing the required chiller capacity in tons, the leaving water temperature and either the chilled water temperature range (Delta T) or the flow, determine the unknown quantity using the formula:

Tons= GPM x Delta T/24 (water only)

Knowing the required chiller capacity (tons), the entering condenser water temperature, and either the condenser water temperature range-delta T, or the GPM, determine the unknown quantity using the formula:

With the previous data, the appropriate unit can be selected from using the performance data tables, which start on Table 20. Correct the capacity and power if conditions are other than standard as described above. Pressure drop for condensers

and for evaporators can be found in Table 24 on page 22 and Table 25 on page 23, respectively.

Sample Selection Given: Cool 115 GPM of water from 58°F to 44°F with condenser water available at 85°F. Condenser water temperature rise to be 10°F. Fouling factor of 0.0001 in the evaporator and 0.00025 in the condenser.

Find:

A. WGZ packaged water chiller selection

B. Compressor power input

C. Condenser water flow rate

D. Corrected EER

E. Evaporator and condenser water pressure drop

Solution:

1. Chilled water range: 58°F - 44°F = 14°F (Nonstandard Temperature Difference).

2. Tons = 115 x 14°F/24 = 67 Tons

3. From Table 20 on page 18, a model WGZ-070DW has the capacity to meet the job requirement. For an evaporator leaving water temperature of 44°F and condenser water entering temperature of 85°F with a 10°F rise, the unit capacity rating table indicates:

• Capacity: 70.2 Tons• Power: 53.3 kW

4. Correct for 14°F Delta-T in the evaporator with factors from Table 18.

• Capacity: 70.2 x 1.015 = 71.2 Tons• Power: 53.3 x 1.004 = 53.7 kW

5. Calculate new EER: (71.2 Tons x 12000) / (53.7 kW x 1000) = 15.9

6. Determine condenser water from the following:

• From Table 25 on page 23, the evaporator pressure drop at 115 GPM is 6.2 feet.

• Condenser flow = 67 Tons x 30/10 degrees=201 GPM. From Table 24 on page 22, the condenser pressure drop at 201 GPM is 9.6 feet water.

Electrical Notes Notes for “Electrical Data Single Point” Power:

1. If a separate 115V power supply is used for the control circuit, then the wire sizing amps is 10 amps for all unit sizes.

2. Recommended power lead wire sizes for 3 conductors per conduit are based on 100% conductor ampacity in accordance with NEC. Voltage drop has not been included. It is recommended that power leads be kept short. All terminal block connections must be made with copper (type THW) wire.

3. The recommended power lead wire sizes are based on an ambient temperature of 86°F (30°C). Ampacity correction factors must be applied for other ambient temperatures. Refer to the National Electrical Code Handbook.

4. Must be electrically grounded according to national and local electrical codes.

Voltage Limitations:1. Within 10 percent of nameplate rating

2. Voltage unbalance not to exceed 2% with a resultant current unbalance of 6 to 10 times the voltage unbalance per NEMA MG-1, 1998 Standard. This is an important restriction that must be adhered to.

Notes for “Field Wiring Data”1. Requires a single disconnect to supply electrical power

to the unit. This power supply must either be fused or use an HACR type circuit breaker.

2. All field wiring to unit power block or optional non-fused disconnect switch must be copper.

3. All field wire size values given in the Electrical Data tables starting on page 44 apply to 75°C rated wire per NEC.

Supplemental Overloads OptionThe supplemental overloads option is used to reduce the required electrical service size and wire sizing (cost) to the packaged version of WGZ chillers (WGZ-DW models). This option is available for units with single point or multiple point electrical power connections. Refer to the data tables starting on page 42 for electrical information on units with and without the overloads option.

Circuit BreakersThe circuit breaker used in the High Short Circuit panel option may have a higher trip rating than the unit Maximum Overload Protection (MOP) value shown on the unit name plate. The circuit breaker is installed as a service disconnect switch and does not function as branch circuit protection, mainly that the protection device must be installed at the point of origin of the power wiring. The breaker (disconnect switch) is oversized to avoid nuisance trips at high ambient temperature conditions.
