combination of the basic modules of 1 the catalog, models of above 316KW

are some typical module-combined products recommended by Haier.

For example: CI0740AANB chiller is composed of one CI0247AANB and two CI0247AANC chillers.

Capacity Regulation Mode

Step Capacity Regulation Mode: Each compressor has four steps of capacity regulation: 100% - 75% -

50% - 25%, among which 25% step is for the startup of compressor.

2. Product character

Haier air-cooled (heat pump) chiller is a comprehensive product developed by Haier. This product series

adopt compressors, system parts and electrical components of well-known brands and they are characterized

by compact structure, cutting-edge technology, reliable control, cost-effective operation and convenient

installation. The computer-controlled system can not only improve control precision and reliability, but also

realize multi-step energy adjustment, through which the balance of chiller capacity and customer load is

optimized and thus to effect economical operation. The chiller is under continuous control by means of large

volume information display. Unattended and energy-saving operation can be realized using the preset

operation mode and operation program. The computer-controlled system can be connected to master computer

so as to render network-based automatic management of the whole building. The air-cooled integral structure

is dispensed with such components as cooling tower and cooling pump and can save project construction cost.

This product can serve as central air-condition system for hotels, stores and office buildings and can meet the

technological air-conditioning requirements in textiles, chemical, metallurgical, pharmaceutical and power

industries.

2.1 Motor

The compressor motor is 3-phase scal perator induction type, and the operation voltage will be confirmed

as per the nameplate.

The inner refrigerant suction system is cooled by the refrigerant.

Started up by Y -△ type

2.2 Compressor

The compressor is equipped with the protection device of discharging temperature, discharging pressure,

suction pressure, motor coil temperature, motor coil, etc.

The unit adopts screw type compressor. Within 3 minutes after startup, the compressor is in the transitional

period.

Note: 1) To avoid the compressor start/stop frequency, once shut off, please do not start up the compressor

in 3 minutes. 2) When several compressors are installed, the time difference of the compressor startup needs to

be set.

The capacity adjustment will be realized by the refrigerant driving the slide valve.

In the compressor there is high efficiency oil segregator.

The screw axis and the rotor are one complete unit in the mold.

2.3 SHELL&TUBE heat exchanger

In cooling mode, SHELL&TUBE heat exchanger is as evaporator, while, in heating mode, it is as

condenser.

The SHELL&TUBE heat exchanger adopts high efficiency copper pipe.

In the SHELL&TUBE heat exchanger, the freezed water will flow out of the copper pipe, while the

refrigerant flow in the copper pipe.

Out of the SHELL&TUBE heat exchanger, there is the heat insulation material.

2.4 Condenser

Condenser adopts the pinned coil type structure, and adopts the high efficiency copper pipe. The condenser

fan motor is with low noise.

2.5 Electric control

Adopt the PCB to control the operation.

The unit can realize remote operation .

The control of water temperature will act according to the water outlet temperature.

The unit can realize compulsorily unit quantity control and compulsorily capacity control for the unit with

several compressors.

When failure occurs, the normal compressor can continue running (for the unit with several compressors).

When abnormal, the unit can monitor the current water temperature, operation time.

In operation, the unit can monitor the water temperature, capacity state, and operation time.

On the crystal touch screen, you can control the unit.

When abnormal, the failure information will display on the crystal touch screen automatically.

The unit can realize the interlock between the cooling .

Note: Do not damage the power cable.

The following items can be tested if abnormal: high pressure, low pressure, compressor motor coil

temperature, compressor discharging temperature, anti-freeze, reverse power supply, etc.

2.6 Safety Device

For the requirement of safety, there is solenoid valve on the discharging pipe to discharge the gas when the

pressure is too high. Must not install any stop valve on the pipe with safety relief valve.

The unit is equipped with safety device to confirm the safe operation. When one safety device acts, the

failure indicator will light, and the corresponding function will stop, while the other function is normal.

Suggestion: Once one section occurs abnormal phenomenon, you should shut off the unit to check

the reason to avoid the worse damage.

Part name

25%—50%—75% compressor capacity
regulation solenoid valve, control the
movement of capacity piston by oil
pressure drop so that the compressor can
adjust the capacity flexibly according to the
actual capacity.

Filter drier, used to remove moisture
and impurit

y

in the refrigerant.

HAIER CHILLER

14

4-way valve, reverse
when electrify is complete
in heating mode

Refrigerant spray hole, enter the
middle of compressor and
reduce the dischar

g

e temp..

Capacity regulation capillary

Oil inlet connector

Oil pressure drop switch,
used to inspect the
pressure drop of the two
side of oil filter

Compressor crankcase
heater, used to heat up

Oil inspect glass, used to
observe the oil lower level
of compressor

Oil outlet connector

Solenoid valve before 4­way valve, used to control
the reverse of 4-wa

y

valve.

HAIER CHILLER

15

By-pass valve, when the
compressor is run in part
capacity, move the
refrigerant from discharging

Low pressure sensor, used
to detect the compressor
suction pressure and
protect when the suction

p

ressure is too low

HAIER CHILLER

16

Liquid spray solenoid valve,
used for compressor
refrigerant spray protection,
prevent the motor of
compressor overheat and
discharging temp. too high.

Thermostatic expansion
valve, control the spray of
refrigerant by liquid-spray
solenoid valve and
discharging temperature
which is detected by the
thermostat.

Thermal expansion
thermostat，fixed on the
discharging pipe.

One-way valve, used
to prevent refrigerant
flow back.

Discharging temp. sensor,
used to detect the
compressor discharging
temp. and prevent
discharging temp. from too
high.

Safety valve, used to decrease
the pressure when the system
pressure is too high.
