Introduction to internal components of industrial chillers
A chiller is a type of water-cooled refrigeration equipment that can provide constant temperature, constant current, and constant pressure refrigeration. Its working principle is to first inject a certain amount of water into the internal water tank, cool the water through the compressor, condenser, evaporator and other refrigeration systems, and then send the low-temperature cooling water to the equipment that needs to be cooled by the water pump. The water takes away the heat and rises in temperature before flowing back to the water tank, achieving the cooling effect. The cooling water temperature can be automatically adjusted according to requirements, and long-term use can save water.
The internal structure of the chiller is also relatively simple. Understanding the various components is of great help for us to better use the chiller and prolong its service life. Oukelong Refrigeration will briefly introduce the control components inside the industrial chiller? 1. The refrigerant of the chiller, also known as the snow type controller, includes expansion valves, capillary tubes, etc; 2. Refrigerant circuit controller: four-way valve, one-way valve, compound 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, 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 voltage alarm, fire alarm, smoke alarm, etc; 6. Other controls: indoor motor speed controller, outdoor fan speed controller, etc.
