Application and Principle of Beijing High and Low Temperature Alternating Damp Heat Test Chamber-Xingwangbao Machinery Equipment Network

Beijing High and Low Temperature Alternating Damp Heat Test ChamberMainly used for reliability testing of industrial products at high and low temperatures. Under low and high temperature conditions, environmental simulation tests are conducted on the product to determine its performance and whether it still meets the predetermined requirements. This is done for product design, improvement, identification, and factory inspection. The Beijing high and low temperature alternating humidity test chamber can be used in industries such as electronics, electrical appliances, communications, instruments, vehicles, plastic products, metals, food, chemicals, building materials, medical, aerospace, etc.

Beijing High and Low Temperature Alternating Damp Heat Test ChamberWorking principle of refrigeration:

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 at an isothermal state, 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 higher temperature objects isothermally through the evaporator, causing the temperature of the cooled object to decrease. This cycle repeats itself to achieve the goal of cooling down.

Beijing High and Low Temperature Alternating Damp Heat Test ChamberThe refrigeration system adopts a unit Freon refrigeration system composed of fully enclosed compressors. 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 regulate the energy consumption and refrigeration capacity of the refrigeration system, so as to maintain the refrigeration system in a * operating state. By adopting balanced temperature regulation, the control system automatically calculates the output of the heater based on the set temperature point through PID calculation when the refrigeration system is working continuously, ultimately achieving a dynamic balance.
