The refrigeration unit of high and low temperature damp heat testing machine is composed of five organizations:

1. Refrigeration compressor

 2. Cooler

 3. Air conditioning evaporator

 4. Electronic expansion valve

 5. Overflow valve

 Refrigeration working principle of high and low temperature damp heat tester:

According to the refrigeration unit, the heating capacity of the compound gas in the commodity is transmitted to the refrigerant with lower temperature than the commodity to reach the destination of reducing the commodity temperature.

 Characteristics of high and low temperature damp heat tester:

1. Heat reduction control: composed of multi-stage air conditioning evaporator, it can obtain more symmetrical and efficient cooling capacity exchange efficiency and refrigerator output. The flow monitoring is automatically adjusted by the electronic expansion valve matched separately.

2. The refrigeration compressor drives the valve equipment, and the output power of the refrigeration compressor can be adjusted in the range of 10% ~ 100%.

3. Environmental protection and energy saving countermeasures: the following reasonable kinetic energy adjustment countermeasures are selected, such as: air conditioning cooling capacity adjustment of refrigeration unit, steam liquid double circuit power supply adjustment, volatilization temperature adjustment, etc. when controlling the temperature at all low temperature points, no heating balance is needed, and the operation output power can be reduced to half, so that the operation cost and repair rate of refrigeration unit can be reduced to the situation of comparative economic development.

4. High and low temperature damp heat test mechanism air return temperature adjustment of the refrigeration compressor: fully automatic adjustment of the air return temperature of the refrigeration compressor to maintain the temperature of the refrigeration compressor within all normal ranges, to prevent the refrigeration compressor from low temperature and over temperature.

5. Refrigeration machine processing technology: in the design scheme of refrigeration unit, it is considered that the guarantee measures for refrigeration compressor, such as the full-automatic maintenance of the working pressure of the suction and discharge pipes of the refrigeration compressor, make the operating temperature of the refrigeration compressor maintain within all normal temperature ranges, prevent the refrigeration compressor from low temperature or over temperature, so as to increase the service life of the refrigeration compressor.
