2. Structural Features and Working Principle 2.1 Main Function SIC-A-R2 air-cooled water chiller mainly comprised of the compressor, condenser, thermal expansion valve and the evaporator, which transforms from gas or liquid refrigerant by air cooling, and adopts heat absorbing and releasing to achieve the refrigerating effect.
bypass valve 21 opens, and the refrigerant changes the low-temp. and low-pressure gas into high-temp. and high-pressure gas under the action of compressor 1, which enters the condenser 3 in the BC direction. Under the action of fan 2, it will accelerate heat exchange with the air, and the refrigerant is changed from gaseous state to liquid state, meanwhile the heat is taken away by the air;...
1) It is the component to discharge the heat. The refrigerant absorbs the heat and discharges it through the condenser. 2) Our company’s air-cooled water chiller uses the female thread fin-style condenser. Picture 2-3: Fin-style Condenser 2.2.3 Drying Filter 1) Drying filter’s function: Remove impurities in the refrigerant, absorb the free moisture in the refrigerant, and prevent blockage at the narrow section of the pipeline (especially at the valve port of thermal expansion valve).
Picture 2-5: Thermal Expansion Valve 2.2.5 Evaporator 1) Evaporator (plate exchange) is a device that outputs the refrigerating capacity. The refrigerant absorbs the water heat in the evaporator to achieve the refrigerating purpose. 2) Adopt plate evaporator that largely improves the heat transfer efficiency. Picture 2-6: Evaporator 2.2.6 High and Low Pressure Sensor 1) The high and low pressure sensors are used to detect the working...

2.2.9 Hot-gas By-pass Valve Picture 2-10: Hot-gas By-pass Valve 1) Used to bypass the refrigerant gas when it gets close to the set temperature as to avoid compressor frequent start and achieve accurate temperature control; 2) Install on the connecting pipe between the compressor outlet and expansion valve outlet.
Picture 2-12: Disk Filter The disk filter is composed of the valve core and valve body. When filtering, press the disk tightly, the water flows through the disk, and the impurities are kept out of the disk or between the grooves, thus achieving the filtering purpose. The disk filter has deep filtering function and excellent blocking function, which features easy operation and maintenance.
Picture 2-14: Refrigerant Indicator Through the water tank refrigerant indicator, it can check whether the water level in the water is in normal range. 20(42)
3. Installation and Debugging Before installation, please read this chapter carefully and install according to the procedures as follows! 3.1 Machine Positioning 1) Install the water chiller near windows or places with good air flowing because air-cooled central water chiller needs a good heat-releasing condition.
Do not change the circuit of the water chiller without our company's authority. If the machine is damaged by unauthorized change we are not responsible for this. 3.3 Installation diagram Names of Parts: 1. Water chiller 2. Chilling water inlet 3.

Check whether there’s pollution Cycle: Daily and scaling inside the water tank, Check whether there are bubbles in and the water quality is dirty or polluted.
In order to operate the machine rightly and safely, please caution the matter follows: 1) Don’t turn off the main power switch to stop the machine, except emergency situation. 2) When the machine shuts down and alarms, check the fault causes, and don’t start the machine forcibly before troubleshooting.
after a long time use of the evaporator, which will influence the heat emission effect, so it is necessary to clean the evaporator at fixed periods in order to keep its working performance. If the circulation has been under water treatment, it is advised that firstly use hydrogen peroxide to kill bacteria and then use a high pressure water rifle to flush it, at last check whether there is still scale scale.
