The operating principle of Hefei high and low temperature test chamber


The high and low temperature test box is mainly used to control products by controlling high temperature, low temperature and humidity. In the internal structure of the high and low temperature test chamber, there are systems for controlling the corresponding ambient temperature, which are divided into a refrigerant circulation system, an air circulation system, and an electrical control system. They control the temperature, humidity and electricity in the high and low temperature test chambers.

The working principle of the refrigeration is that the refrigeration cycle adopts the inverse Caro cycle, and the cycle refrigeration is completed through the two-state isothermal process and two adiabatic processes. The specific process is as follows: The refrigerant is adiabaticly compressed by the compressor to a higher pressure, and the work consumed consumes the exhaust gas temperature. After that, the refrigerant performs heat exchange with the surrounding medium through the condenser to transfer heat to the surrounding medium. The rear refrigerant performs work through adiabatic expansion of the shut-off valve, at which time the refrigerant temperature decreases. The refrigerant after the Zui isothermally absorbs heat from an object with a higher temperature through an evaporator, thereby reducing the temperature of the object to be cooled. This cycle repeats itself to achieve the purpose of cooling.

The heating of the high and low temperature test box is mainly composed of air electric heating wire, heating public service system and air circulation system. The heating method generally uses nickel-chromium alloy electric heating wire directly. When the equipment is required to heat up, the circulating fan will cause convection of the air, and the heat generated by the heating wire will be brought into the working room and continuously circulated to achieve the purpose of heating the air in the box. And this process is controlled by a control system through a microcomputer to ensure that the heating and loss heat reach a dynamic balance and achieve the purpose of accurate temperature control.

The working principle of the high and low temperature test box refrigeration is mainly through the adiabatic compression of the refrigerant through the compressor to a higher pressure. The work consumed will make the exhaust temperature high. After that, the refrigerant passes through the condenser and heat exchanges with the surrounding medium. After the heat is transferred to the surrounding medium, the refrigerant passes through the adiabatic expansion of the shut-off valve to perform work. This is the maximum temperature of the refrigerant. Finally, the refrigerant sucks the temperature away through the evaporator and other components, which rapidly reduces the temperature of the object to be cooled. And this cycle continues to achieve the purpose of cooling. However, when choosing a refrigerant, it is best to choose a refrigerant with a higher purity, so as to avoid excessive moisture in the equipment to cause frost.
