Cold Room Condenser's Workflow

2 Years Ago


The Cold Room Condenser, like other condensers, consists of multiple control devices. They are: Refrigerant controller: expansion valve, capillary tube, etc. Refrigerant circuit controller: four-way valve, one-way valve, double valve, solenoid valve. 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. Cooling water control: water cut-off relay, water volume regulating valve, water pump, etc. Alarm control: over-temperature alarm, over-humidity alarm, under-voltage alarm, fire alarm, smoke alarm, etc. Other controls: indoor fan speed controller, outdoor fan speed controller, etc.
Freon 12 (CF2Cl2) code is R12. Freon 12 is a colorless, odorless, transparent, and almost non-toxic refrigerant, but when the content in the air exceeds 80%, it can cause suffocation. Freon 12 will not burn or explode. When it comes in contact with an open flame or the temperature reaches 400°C or higher, it can decompose hydrogen fluoride, hydrogen chloride, and phosgene (CoCl2) which are harmful to the human body. R12 is a widely used medium temperature refrigerant, suitable for small and medium-sized refrigeration systems, such as refrigerators and freezers. R12 can dissolve a variety of organic substances, so ordinary rubber gaskets (rings) cannot be used, and chloroprene elastomer or nitrile rubber sheets or sealing rings are usually used.
