C) Others

The controller board comes with other option.

i) Unoccupied Mode If the dry contact is closed, the Unoccupied mode is activated and vice versa. When Timer On is active,

system goes back to Occupied mode. The dry contact connection points can be connected parallel with other fan coil unit (FCU) boards. If the

dry contact is closed, Unoccupied mode will be activated on all fan coil units that are connected parallel as shown in figure below.

ii) Anti Freeze Mode Anti Freeze operation has the highest priority among all unit operation. Anti Freeze operation will be activated

only if dry contact is closed and vice versa.

iii) Window Open Mode The dry contact connection points can be connected in parallel with other fan coil unit (FCU) boards. If the

dry contact is closed, Window open mode will be activated on all the fan coil units which are connected in parallel as shown in figure below.

iv) Load Shedding The dry contact connection points can be connected in parallel with other fan coil unit (FCU) boards. If the

dry contact is closed, Load shedding mode will be activated on all the fan coil units which are connected in parallel as shown in figure below.

Global Unoccupied, Global Window Open and Global Load Shedding operation could also be activated via the network communication bus line by master controller with or without the above connection.

NOTE :i) Auto Fan Mode is only applicable in Model 3 only. ( Cooling only with Boiler) ii) Fan mode is not available in valveless control.iii) Wired handset (Netware and SLM) has an indoor room sensor. Avoid locating the wired handset at isolated

places where room temperature reading will be inaccurate.


13

Water Piping Connection

The indoor unit is equipped with water outlet and inlet bare connection. There is an air-vent for air purging that is fitted at the outlet water header.

3 ways solenoid valve is required for cycling off or bypass the chilled water.

Black steel pipe, polyethrene pipe, PVC pipe and copper tube recommended in field installation.

All types of piping and connection must be insulated by polyurethane (ARMAFLEX type or equivalent) to avoid condensation.

Do not use contaminated or damaged pipe and fitting for installation.

Some main fitting components are needed in the system to enhance the capacity and ease of service, such as gate valve, balancing valve, 2 ways or 3 ways solenoid valve, filter, strainer etc.

Preliminary Site Survey

Electrical supply and installation is to conform to LOCAL AUTHORITY’s (e.g. National Electricity Board) CODES and REGULATIONS.

Voltage supply fluctuation must not exceed ± 10% of rated voltage. Electricity supply lines must be independent of welding transformers which can cause supply fluctuation.

Ensure that the location is convenient for wiring and piping.

Mounting

For ceiling mounted models, locate a position where piping and ducting work can be kept to a minimum. Ensure that overhead supports are strong enough to hold the unit’s weight. Position hanger rods and check for alignment with the unit. Check that hangers are secure and that the base of fan coil unit is level in two horizontal positions.

Piping

Drain and water piping must be accurately connected.

Please refer to “Specification Sheet” for piping sizes.


14

Piping Support

All water mains must be adequately supported to carry the necessary weight involved, provisions must be made by the installing contractor to allow for adequate free movement of all vertical and horizontal risers and run outs. Due to the fact that cold water will be circulated through the water mains, a sizeable movement of the water mains can be expected due to contraction. If for example, the piping is rigidly supported with no provision for movement, it is very possible that the tubing of fitting may be broken causing water leakage in the conditioned spaces throughout the building.

Coil Venting

Each standard basic unit coil is equipped with a manually operated air vent which is installed at the end of a small copper line leading into the highest point of the coil. By means of this valve, air may be vented manually, from the coil to keep it operating at full capacity. When water is first introduced into a coil, air is sometimes trapped in the coil tubing. This trapped air will reduce cooling capacity and create “Bubbling” or “Clanking” noise within the units. To release air trapped in the coil, press the air vent head to allow air to flow out of the air vent opening. Release when a steady stream of water appear.

Electrical Connection

As wiring regulations differ from country to country, please refer to your LOCAL ELECTRICAL CODES for field wiring regulations and ensure that they are complied with. Besides, take note of the following general precaution:

1) Ensure that the rated voltage of the unit corresponds to the name plate before commencing wiring work.

2) Provide a power outlet to be used exclusively for each unit and a power supply disconnect and a circuit- breaker for over-current protection should be provided in the exclusive line.

3) The unit must be EARTH to prevent possible hazards due to insulation failure.

4) All wiring must be firmly connected.

MFCU_(ii) Performance Data

The cooling and heating capacities of the fan coil units can be determined by the Cooling Capacity Perfor-mance Chart and Heating Capacity Performance Chart in the following pages based on nominal air flow atstandard water temperature. The total and sensible capacities must be adjusted as variables come in. A sampleof selection procedure is given as below:

Step 1Determine type of fan coil units to be used, i.e. ceiling cassette (MCK-AW Series); ceiling exposed (MCM-DWSeries); etc.

Step 2Select a tentative unit size based on cooling capacities at nominal air flow. Design entering air temperaturesand required water flows from cooling capacities chart (Page 59 - 102) or the nominal capacities ratings (Page45 - 55) from standard specification.

Step 3Determine the nominal unit cooling capacities for the unit selected. If the cooling capacities chart must be used,the following information must be known :-

a) Design water temperature riseb) Design entering water temperaturec) Design entering air dry bulb temperatured) Design entering air wet bulb temperature

Example of how to read the cooling performance chart.

Step 4If air flow value is different from the nominal value(high speed), then refer to specification from Page 40 to 42for the air flow required (medium or low speed). Determine the total and sensible correction factor from Air FlowCapacity Correction Factor (Page 40 to 42)

Step 5If the unit is to operate at an altitude above sea level, multiply the capacity correction factors by an AltitudeCorrection Factors. Refer to Page 42.

Step 6Calculate the actual cooling capacity by multiply the nominal capacity (from Step 3) with Air Flow CapacityCorrection Factor from Step 4 and the Altitude Correction Factor from Step 5.

Actual Capacity, W = Nominal capacity (Step 3) x Air Flow Capacity Correction Factor (Step 4)x Altitude Correction Factor (Step 5)

Step 7Water flow rate can be determined by:

Litres/Min = Total Cooling Capacity, W 70 x Water Temperature Rise °C

USGPM = Total Cooling Capacity, Btu/H 500 x Water Temperature Rise °F

Step 8Heating Capacities at nominal air flow (Page 103 to 107 - Heating Performance Chart) are based onstandard condition of 60°C EWT and 21°C EAT. The actual heating capacity can be obtained by using theHeating Capacity Correction Factor (Page 43 to 44) and Altitude Correction Factor as per Step 5.

Hence Actual Heating Capacity, W = Nominal Capacity (Page 137 to 141) xHeating Capacity Correction Factor (Page 49) xAir Flow Capacity Correction Factor (Step 4) xAltitude Correction Factor (Step 5)

Step 9Water Pressure Drop Tables are on Page 33 to 39.

EXAMPLESelect a ceiling cassette type fan coil unit at the following design specification:

Room design condition : 27°C DB / 19°C WBRoom Cooling Load : 8 kW sensible capacity / 11 kW total capacityRoom Heating Load : 22 kWEntering water temperature : 7°C cooling / 70°C heatingWater temperature rise : 5°CAir Volume : 1000 CFM

m 006 :edutitlA

SOLUTIONStep 1Based on the type of fan coil required and the design conditions, tentatively select MCK050AW. From the cooling capacity performance chart (Page 80), at 26.7°C DB / 19°C WB air temperature, 7°C entering water temperature and with 5°C water temperature rise, the cooling capacity for this unit is 11.7 kW total capacity and 8.5 kW sensible capacity.


58

Step 2

Step 3As the unit is operating at 600m above sea level, the Altitude correction factor is 0.98 total and 0.93 sensible.

Step 4Multiply the cooling capacities obtained from step 1 (as per specification and design condition) by correctionfactors from (2) and (3)

Actual total cooling capacity = 11.7 x 1.0 x 0.98 kW = 11.47 kW

Actual sensible cooling capacity = 8.5 x 1.0 x 0.93 kW = 7.91 kW

Step 5Water flow rate = Litres/M = 11470 W = 32.8

70 x 5

Step 6From Heating Capacity Performance Chart (Page 102), determine the heating capacity at the nominal airvolume by using the flow rate calculated in step 5. The heating capacity is at 20.6 kW.

Step 7From Heating Capacity Correction Factor Tables at 70°C water entering temperature and 26.7°C entering airtemperature, the correction factor is 1.1261,

Actual Heating Capacity= 20.6 x 0.98 x 1.1261 = 22.7 kW

Step 8Water Pressure Drop can be estimated from water Pressure Drop Table (Page 33 to 39) using interpolatemethod:

At flow rate of 32.8 Litres/Min, the nominal pressure drop is 39.14 kPa

Pressure drop correction factor = 1.2947 - 0.0021 x (EWT°C x 1.8 + 32) = 0.9629

Hence the actual pressure drop = nominal pressure drop x correction factor = 37.69 kPa.
