Shanghai Rapid Temperature Change Test ChamberSuitable for judging the reliability and stability performance of aerospace products, information electronic instruments, materials, electrical and electronic products, and various electronic components in high and low temperature or humid and hot environments. We will provide you with a basis for predicting and improving the quality and reliability of our products. So, how much do you know about the refrigeration system of the experimental equipment? Below, our editor will give you a detailed introduction!

　　Shanghai Rapid Temperature Change Test ChamberDivided into three parts: high temperature zone, low temperature zone, and testing zone, it adopts original Japanese made microcomputer large LCD and Chinese English display control system. Equipped with a fully automatic, high-precision system, any component action is locked and processed by P.L.C; When there is a mechanical failure, it is equipped with automatic circuits and warning signals. If the input voltage is found to be unstable, it has an emergency stop device.

　　Shanghai Rapid Temperature Change Test ChamberThe heating, cooling, and humidification system can independently increase efficiency, reduce testing costs, extend lifespan, and decrease failure rates. The refrigeration unit adopts the original French "Taikang" fully enclosed compressor unit. The refrigeration system adopts a unit or binary low-temperature circuit system design. The multi wing air supply fan in the United States provides strong air circulation, avoiding any dead corners and ensuring even temperature and humidity distribution in the testing area.

　　Shanghai Rapid Temperature Change Test ChamberMainly simulate the inspection of electronic components under high temperature, low temperature, or humid and hot natural environmental conditions. Generally used in military aviation, electronic information, instrumentation, electronics and electrical engineering, automobiles, ships, universities, scientific research and other units. The electrical components of this device mainly include three major structural components: heating system, cooling system, and control system.

1、 The control system of the rapid temperature change test chamber: The core controller adopts the imported "OYO" from Japan, and the touch screen controller adopts the "TEMP850" LCD touch screen controller from South Korea. The control program is developed through human-machine dialogue, and only the temperature needs to be set to enable the automatic operation of the refrigeration machine.

In addition, solid-state relays trigger zero crossing to reduce noise, minimize pollution, facilitate maintenance, improve control accuracy, and are equipped with safety protection measures, including phase loss protection, phase sequence error protection, phase voltage imbalance protection, fan overload protection, over temperature, power-off protection, unit high voltage protection, unit overload protection, unit over temperature protection, leakage protection, etc.

2、 Rapid temperature change test chamber refrigeration system: fully enclosed compression refrigeration (original "Taikang" from France), fully enclosed air-cooled cascade compression refrigeration method. The cascade refrigeration system includes a high-temperature refrigeration cycle and a low-temperature refrigeration cycle, and its connecting container is an evaporative condenser. The evaporative condenser also plays a role in energy transfer, transferring the heat energy in the working chamber through a two-stage refrigeration system to achieve the purpose of high temperature. The design of the refrigeration system applies energy regulation technology, which is an effective way to ensure the normal operation of the refrigeration unit while effectively adjusting the energy consumption and cooling capacity of the refrigeration system, reducing the operating costs and failure rate of the refrigeration system to a more economical state.

IIIShanghai Rapid Temperature Change Test ChamberHeating system: It is mainly composed of high-power resistance wires. Due to the high heating rate required by the rapid temperature change machine, the heating system power of the test box is relatively high, and a heater is installed on the bottom plate of the test box.
