Les éléments de contrôle interne du refroidisseur

The chiller is a kind of water cooling equipment, which can provide cooling water equipment with constant temperature, constant current and constant pressure. Its working principle is to first inject a certain amount of water into the water tank in the machine, cool the water through the refrigeration system, and then send the low-temperature cooling water to the equipment that needs to be cooled by the water pump. water tank to achieve the purpose of cooling. The cooling water temperature can be automatically adjusted according to the requirements, and the long-term use can save water.

Internal control components of industrial chillers:

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

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

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

4. 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;

5. Alarm device: over-temperature alarm, over-humidity alarm, under-voltage alarm, fire alarm and smoke alarm.
