Cold storage mainly consists of cold storage body (formed by the library board or spraying), cold storage door, compressor unit (unit consists of compressor, condenser , solenoid valves, filters, pressure control, oil separation, etc.), evaporator (chiller or exhaust pipe), control box, cut-off device (expansion valve), lighting system, alarm system, protection system, connecting copper pipe and electric wire and other components.
The cold storage basically consists of the following parts:
1, storage body.
2, refrigeration unit (compressor, condenser, condensing fan or cooling tower, etc.).
3, evaporator.
4, electric control box.
5, expansion valve.
6, copper pipe.
7, refrigerant, library lights and other electrical parts.
The main role of the cold storage
The main role of the cold storage of food, dairy products, meat, aquatic, chemical, pharmaceutical, nursery, scientific experiments, etc., constant temperature storage of cold air equipment, cold storage is actually a low-temperature cold storage (cold storage) also belongs to one of the refrigeration equipment and refrigerators compared to the refrigerator, the refrigeration area to be a lot larger, but they have a common refrigeration principle.
1, the traditional detector can not be used. Traditional fire detectors are not suitable for installation inside the cold storage, due to the low temperature inside the cold storage, will cause the detector frost or failure.
2, fire hazards. Air conditioning and refrigeration equipment, goods transfer equipment, lighting equipment and other electrical or mechanical failure, polystyrene foam insulation, plastic packaging materials, wooden pallets filled with cold storage interior. The temperature inside the cold storage is very low, the long-term cause of the cable line plastic skin becomes brittle and easy to break, further causing the line short-circuit and combustion, and the air inside the cold storage is unusually dry, after the fire burns very quickly.
