A device that cools gases into liquids and condense it. The condenser coils that Thermo reefer units for trucks and refrigeration units for vans equipped with are aluminum micro-channel parallel flow coils, which makes the cooling effect of the transport refrigeration units achieve the best.
A device in the transport refrigeration units that allows a compressed cooling chemical, such as R134a, R404a, to evaporate from liquid to gas while absorbing heat in the process.
A mechanical device that pumps the refrigerant gases produced in the evaporator and compressed the gases into the condenser.
4. Expansion Valve
A valve used to control the flow of refrigerant and reduce the pressure by regulating flow.
Asubstance or mixture, usually a fluid, used in a heat pump and refrigeration cycle. So the substance was chosen to be refrigerant should have a good thermal property and satisfying physical and chemical property. And the selection and use of the refrigerant should consider the occasion, temperature requirement, the quantity of refrigerating and the type of refrigerator comprehensively.
6. Refrigeration Oils
It is used to lubricate all fiction surfaces of the compressor and reduce the parts’ wear, improve mechanical efficiency, reliability and durability. Also it plays a great role in cooling system cleaning and gas proof. And it can be used as hydraulic power oil in the compressor to regulate energy. So the main functions of refrigeration oils are lubricating, sealing, cooling and energy regulating four parts.
7. Auxiliary equipment
Mainly consist of oil separator, reservoir, filter driver, gas-liquid separator, sight glass.
