Working principle

Walk-in constant temperature and humidity test Chamber working principle:

Working principle of refrigeration: The refrigeration cycle uses the reverse Karol cycle, which produces two isothermal processes and two
It consists of an adiabatic process. The process is as follows: the refrigerant is adiabatically compressed to a higher pressure by the compressor, and the work consumed causes the exhaust temperature to rise. After that, the refrigerant undergoes heat exchange isothermally with the surrounding medium through the condenser to transfer the heat to the surrounding medium. Surrounding medium. After the refrigerant passes through the shut-off valve, the adiabatic expansion does work, and the temperature of the refrigerant decreases. Finally, the refrigerant absorbs heat isothermally from the higher temperature object through the evaporator, causing the temperature of the object to be cooled to decrease. This cycle repeats itself to achieve the purpose of cooling. The refrigeration system of this test chamber uses a unit Freon refrigeration system composed of a French-made Taikang fully enclosed compressor. The design of the refrigeration system applies energy regulation technology, which can not only ensure the normal operation of the refrigeration unit, but also effectively adjust the energy consumption and cooling capacity of the refrigeration system to keep the refrigeration system in optimal operating condition. Using balanced temperature control (BTC), when the refrigeration system is continuously working, the control system controls the output of the heater according to the set temperature point through the PID automatic calculation output, and finally achieves a dynamic balance.
