Introduction of internal control elements of industrial chillers
Chiller is a kind of water cooling equipment, which can provide constant temperature, constant current and constant pressure cooling water equipment. Its working principle is to inject a certain amount of water into the internal water tank of the machine, cool the water through the refrigeration system, and then send the low-temperature cooling water to the equipment to be cooled by the water pump. , To achieve the role of cooling. The cooling water temperature can be automatically adjusted according to requirements, and long-term use can save water.

Briefly introduce the control elements inside the industrial chiller.

1. Chiller refrigerant controller: expansion valve, capillary, etc .;

2. Refrigerant circuit controller: four-way valve, one-way valve, double valve, solenoid valve;

3. Refrigerant pressure controller: pressure switch, output pressure regulating valve, pressure controller, motor protector, overcurrent relay, thermal overcurrent relay, temperature relay, temperature regulator, temperature position regulator, temperature Proportional regulator, humidity regulator, humidity level regulator, defrost controller, defrost temperature switch, defrost time relay, various temperature switches;

4. Cooling water control: water cut-off relay, water volume regulating valve, water pump, etc .;

5. Alarm control: over temperature alarm, over humidity alarm, under pressure alarm, fire alarm, smoke alarm, etc .;

6. Other controls: indoor fan speed controller, outdoor fan speed controller, etc.
