2 Efficiency level, Digit 12
2.1 Standard efficiency, Digit 12 = 1
2.1.1 Description
EER at 12/7 OAT=35°C: SE is class B or C (Eurovent efficiency) when operating at full load.
Standard efficiency, units use AC fan motors with three-phase on the condenser. The motor
and the ball bearings are permanently lubricated and overload protection is provided.
However, if the unit has Low Ambient (Digit 15= C) then it will have one EC fan per circuit.
2.2 High efficiency, Digit 12 = 2
2.2.1 Description
HE version remains with the same compressors, exchangers and airflow of SE version.
The EER in High efficiency unit is the same value of a standard unit, but the ESEER is much
higher because it counts with an adaptive control that improves the efficiency in partial load
operation. Best compromise between number of compressors in operation and airflow (fans’
rotation)
High efficiency units are always equipped EC fan brushless motor, operating with direct
current. EC Fan: the basis is similar to the principle of a frequency inverter; the motor speed
depends on the voltage provided by the integrated module. All fans will be driven at the same
speed.
2.2.2 Benefits
High efficiency and a significant reduction of energy consumption at partial load.
2.3 AC & EC fans Characteristics.
The motors of both fans are Insulation class F and Ingress protection marking IP54.

14 | P a g e
No heaters are provided but the anti-freeze protection is possible with the pump activation
using external temperature sensor. This system allows reducing the price and consumption
of the unit.
4.3.2 Description
As no heaters are provided, the system will make water flows so it heats by friction. The
system counts with a 3 way valve that will let the water flows throw the system or make it flow
in a loop without entering to customer water circuit.

4.3.3 Operation
While the unit is OFF, the pumps are controlled by the CH535 control depending on the
temperature read by the external temperature sensor. The pumps will start when the ambient
temperature is less than 2°C AND the leaving water temperature is less than 15°C; if
conditions both conditions are valid, the operation of the pump will be 5 min ON / 10 min
OFF.

20 | P a g e
Image 16 Micro Channel Heat Exchanger
7.3.1 Application
Aluminum Micro Channel Heat Exchanger is standard for all CGAX chillers.
7.3.2 Description
- The fully-brazed construction micro channel coil increases the coil rigidity making
them more rugged to resist the rigors of job site handling and damage due to
shipping. The micro channel coil's headers, tubes and fins are assembled and then
sprayed with a powder flux bonding agent. The coil is then sent through a large
controlled air automated brazing furnace that completely joins these separate pieces
as one solid micro channel coil.
- The bottom and top tubes of each coil section are always inactive refrigerant paths,
this is done to prevent refrigerant leaks due to corrosion that may be present from
moisture resting between the top or bottom tube and the gasket material and also
serve as a buffer during the installation and removal of the coil section.
21 | P a g e
Image 17 MCHE's parts
7.3.3 Benefits
This process substantially decreases the chances of leaks due to improper brazing
techniques. Each fin surface is angled and louvered to create air turbulence through the coil
which provides more efficient and enhanced heat transfer without additional air pressure
drop through the coil.

8.2 Partial Heat Recovery (PHR), Digit 24 = 2
8.2.1 Application
When part of the rejected heat needs to be recovered for heating water.
8.2.2 Description
One brazed plate heat exchanger per circuit is placed on the discharge line between the
compressor and the condenser coil as shown in the following picture (CXAX). The system
has neither freeze protection nor isolation on water side.
Figure 13 CXAX PHR diagram
Image 19 PHR's location
8.2.3 Operation
24 | P a g e
At the discharge line of the compressor, refrigerant is de-superheated by transferring its
sensible heat to the water which will rise its temperature. At full load conditions (PHR EWT=
40°C / LWT=45°C - OAT = 35°C - EVAP EWT= 12°C / LWT= 7°C), 20% of the cooling
capacity can be recovered.
Figure 14 PHR’s Operating map
Even if the heat exchanger has on site water connections, the customer shall provide the
water loop for partial heat recovery; that means: a circulation pump provides constant
water flow rate from the tank; three-way valve to adjust the water flow of PHR heat
exchanger based on the heat exchanger leaving water temperature (As the leaving water
temperature increases, the PHR water flow rate increases) and safety elements such as
expansion tanks and safety valves

8.2.4 Benefits
- Recuperation of part of the heating rejected capacity.
- Energy saving

9.2.2 Description
Factory-installed, located in electrical panel of the unit.
9.2.3 Operation
- In this circuit, the soft starter replaces the direct on line starter.
- It controls the current flow which will generate the compressors to start gradually.
9.2.4 Benefits
- With the soft starter, the starting current drops down to 2.5 - 3 IN (IN: nominal
intensity).
- The compressor can start smoothly as the starting current is reduced.
- Smooth starting reduces motor and compressor wear.
- Less stress on the power supply.
9.2.5 Incompatibilities
Direct on Line.
9.2.6 More detail
There is a device called Silicon Controlled Rectifier (SCR) that soft starter works with. The
SCR is an electronic switch which allows current to flow through it only when electronic signal
is applied to its gate.
Comparison between across line starter and soft starter:
By installing soft starter in the circuit, it will reduce the starting current. There are 5 different
sizes of compressor.

As shown in table 8, inrush current is reduced by installing soft starter to the electrical
circuit. Thus, the compressor will be started up with small quantity of current and it improves
the stability of the power supply. In table 9, it shows that the compressor with soft starter will
take more time to run than with across the line starter. It means that the compressor starts
progressively.

The goal of this alternative is to provide appropriate flow rate and hydraulic balance, without
the need of mechanical balancing valve, but, taking advantage of the energy consumption
optimization of the pump.
15.2.2 Description
Unit is equipped with a pump package driven by a speed inverter, but without providing
continuous modulation of the speed, the water flow is fixed during the commissioning.
Image 31 VFD Interface representation
15.2.3 Operation
The pump speed limits must be set during the chiller commissioning, and in accordance with
below rules:
Pump speed high limit should be referenced to the Nominal Water Flow Rate
Pump speed low limit should be referenced to the Minimum Water Flow Rate

15.3 Variable primary flow (Constant ΔT), Digit 36 = C
15.3.1 Application
The goal of this alternative is to provide a flow rate in order to maintain constant the delta
between the inlet and outlet temperatures in the evaporator. This solution can be applied on
water loops with 2 or 3 ways valves, and can deliver higher energy saving than constant DP
in the majority of the comfort applications.
15.3.2 Description
With this option, Conquest chillers will be equipped with a pump package driven by a speed
inverter, the modulation of the pump speed is handle to ensure that chiller DT keeps
constant. At minimum system partial load, minimum flow rate must be ensured through the
chiller evaporator.

15.4.1 Application
42 | P a g e
This solution is recommendable on installations with 2 ways valves on the water coils. This
method ensures that each branch of the water loop has an uniform supply, without
unnecessary energy consumption.
15.4.2 Description
Unit is equipped with a pump package driven by a speed inverter; the modulation of the
pump speed is made in order to ensure that the Differential Pressure (DP) remains constant
within the system. At minimum system partial load, minimum flow rate must be ensured
through the chiller evaporator.
Figure 29 Contant ΔP Control diagram
15.4.3 Operation
Delta pressure is measured by 2 ratiometric pressure sensors factory mounted. The
modulation control logic, PI, of the pump speed starts as soon as pump is in operation, in
accordance with DP set point fixed on the unit controller. If the load decreases, the control
valves are closed and that increases the Delta P, then the speed of the pump is decreased in
order to decrease de Delta P until the setpoint. (Decreasing the speed to the half, decreases
consumption in to 1/8)

18.1 Standard Noise (SN), digit 15 = X
18.1.1 Application
When the unit is requested for a non-noise sensitive area.
18.1.2 Description
The fans are placed below the roof.
18.1.3 Operation
The chiller operates with a sound power level in between 83 to 89 dB(A)
18.2 Low Noise (LN), digit 15 = L
18.2.1 Application
When the unit is requested for a noise sensitive area.
48 | P a g e
18.2.2 Description
- Compressors are insulated with sound jacket attenuator.

21.2.3 Operation
- If any fault linked is detected, the compressor is stopped.
- Overvoltage and undervoltage detection (RM4TR):
o In normal operation, the relay is energized and LEDs U and R are lit.
o If the average of the three voltages between phases fluctuates outside the
range to be monitored, the output relay is de-energized.
- Overvoltage: the Red LED “> U” on
- Undervoltage: the Red LED “< U” on
21.2.4 Benefits
- All motors are fully protected.
- Relay RM4 TR provides a phase reversal protection and under/over voltage
protection
