 Third, the refrigeration system 
 1. And compressor cooling system: imported by the French, "Tai" closed compressor, evaporator, condenser composed of single-stage air-cooled refrigeration system, making the minimum temperature cryostat tank to meet the requirements; 
 2. Working principle of refrigeration: refrigeration cycle are used reverse Carnot cycle, the cycle consists of two isothermal and two adiabatic components. The process is as follows: adiabatic compression of refrigerant through the compressor to a higher pressure, power consumption so that the exhaust temperature, then the refrigerant heat exchange with the condenser, the heat to the condenser, the condenser temperature rise high, the heat from the condenser fan blowing on the heat, reduce the temperature of the refrigerant, cooling effect. Finally, the refrigerant into the evaporator by the capillary, the refrigerant in the evaporator of volume expansion, the temperature suddenly drop, so that other quantities of objects from a higher temperature to absorb heat, so lower the temperature by cooling the object. This loop cooling cycle so as to achieve the purpose; 
 3. Cooling: Air Cooled, with wavy fin-type forced air condenser;
