Cooling
After the liquid refrigerant absorbs heat of the object to be cooled in the evaporator, the low-temperature low-pressure vaporized into steam, is sucked into the compressor, compressed into a high pressure high temperature steam into the condenser, the condenser of the cooling medium (water or air ) heat, condenses to a high pressure fluid through the throttle valve is throttled to low pressure and temperature of the refrigerant enters the evaporator absorbs heat of vaporization once again, to cycle refrigeration purposes. Thus, the refrigerant passes through the evaporator in the system, compression, condensation, a throttling process is complete the four basic refrigeration cycle.
The main parts are the compressor, condenser, evaporator, expansion valve (or capillary supercooling control valves), four-way valve, double valves, check valves, solenoid valves, pressure switches, fusible plugs, the output pressure regulating valve, pressure controller, liquid storage tanks, heat exchangers, collectors, filters, dryers, automatic opening and closing, closing valves, liquid injection plugs and other components.
Electrical
The main parts are the motor (compressor, fan, etc. use), the operation switch, magnetic contactor, chain relays, over current relays, thermal overcurrent relay, temperature controller, humidity regulator, temperature switch (defrost, to prevent freezing etc. use). Compressor crankcase heater, water relays, computer boards and other components.
Control
Composed by multiple control devices, which are:
Refrigerant Controller: an expansion valve, capillary.
Refrigerant loop controllers: four-way valve, check valve, double valve, solenoid valve.
Refrigerant pressure controller: pressure opening and closing, the output pressure regulating valve, pressure controller.
Motor protection: over-current relay, thermal overcurrent relay, temperature relay. Temperature regulator:
Temperature-position adjustment, temperature proportional regulator. Humidifier: Humidity bit regulator.
Defrost Controller: defrost temperature switch, defrost relay, various temperature switch.
Cooling water control: without water relays, water regulating valves, pumps and so on.
Alarm control: over-temperature alarm, over wet alarm, undervoltage alarm and fire alarm, smoke alarm.
Other Controls: indoor fan speed controller, the outdoor fan speed controllers.
