The increase in the service life of the constant temperature and humidity experiment box is not only related to the collective maintenance of the equipment, but also has a lot to do with the maintenance of individual parts inside the equipment. There is not a good saying: details determine success or failure. If the maintenance of the internal parts of the experiment box is in place, then the maintenance of the experiment box will be more effective. So now the editor specially explains the maintenance items of the condenser in the equipment:

1. Refrigeration system 　　

   Cooling is an important part of this constant temperature and humidity experiment box, and an important parameter for judging the function of a device. This device is composed of compressor, condenser, saving device, and evaporator. Among them, the compressor is the " heart " of the refrigeration system. It can convert low-temperature and low-pressure gas into high-temperature and high-pressure gas, and condense into liquid to release heat, which is taken away by a fan to achieve a cooling effect.

   
   

2. In order to ensure the demand for cooling rate and lower temperature of the experiment box, the refrigeration system of this experimental instrument uses a cascade refrigeration system composed of imported compressors. This refrigeration system is equipped with reasonable matching, convenient operation and high reliability. The advantages. 　

   　

3. The principle of refrigeration operation 　　

   The refrigeration cycle is composed of two isothermal processes and two adiabatic processes. The refrigerant in the constant temperature and humidity experiment box is adiabaticly compressed to a relatively high pressure by the compressor, which consumes work and raises the temperature of the exhaust gas. After that, the refrigerant exchanges heat through the medium around the condenser and transfers the heat to the surrounding medium.
