制冷原理
The high and low refrigeration cycles of the rapid temperature change test chamber both adopt the inverse Carnot 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, consuming work to increase the exhaust temperature. Then, the refrigerant exchanges heat with the surrounding medium through the condenser at an isothermal state, transferring heat to the surrounding medium. After the refrigerant undergoes adiabatic expansion through the 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.
