Desktop constant humidity testing machineworking principle:The refrigeration cycle adopts a reverse Caryol cycle, which consists of two isothermal processes and two adiabatic processes. The process is as follows: the refrigerant is adiabatically compressed to a higher pressure by the compressor, and the work consumed increases the exhaust temperature. Then, the refrigerant exchanges heat with the surrounding medium through the condenser isothermal, transferring heat to the surrounding medium. After the refrigerant undergoes adiabatic expansion through the shut-off valve, the temperature of the refrigerant decreases. *The refrigerant absorbs heat from objects with higher temperatures through the evaporator, causing the temperature of the cooled object to decrease. This cycle repeats itself to achieve the goal of cooling down. The refrigeration system of this test chamber adopts a binary cascade Freon refrigeration system composed of one set of French made Taikang fully enclosed compressors. The design of the refrigeration system applies energy regulation technology, which can ensure the normal operation of the refrigeration unit and effectively regulate the energy consumption and cooling capacity of the refrigeration system, keeping the refrigeration/dehumidification system in the best operating state. By adopting the Balanced Temperature and Humidity Control (BTHC) method, the control system automatically calculates the output of the heater based on the set temperature point through PID calculation while the refrigeration system is operating continuously, ultimately achieving a dynamic balance.
