What are the difficulties of temperature and humidity precision control technology in high temperature and humidity test chamber
The high temperature and high humidity test chamber is suitable for testing the quality of products such as electronics, plastic products, electrical appliances, meters, food, vehicles, metals, chemicals, building materials, aerospace, medical ...
Rectangular double-glazed glass viewing window, which can be used for observing the test product during the test. The window has a sweat-proof electric heater device to prevent water vapor from condensing water droplets, and the high-brightness PL fluorescent lamp keeps the lighting in the box. Observe the effect.
The double-layer isolation of the box door is tight and airtight, which can effectively isolate the internal temperature leakage. If the temperature in the box is too high, please do not open the box door to avoid scalds. If the temperature is too low, do not open the box door to avoid freezing. There is a piece of humidifying cloth in the box, which has an external water supply system, which is convenient for supplementing the water supply of the humidifying barrel, and it can be automatically recycled. If there is no water recovery, the tester will give an alarm, so the wet cloth should be cleaned frequently. The controller has multi-segment program editing and temperature, humidity can be quickly (OUICK) or slope (SLOP) control.
A Temperature range: What is the temperature range of the equipment, you can select the highest temperature and the lowest temperature value to select ± 2 ﹪ ℃
B cycle function: whether the device has temperature cycle function.
C Humidity range: whether the equipment has a humidity function, + 2 ﹪, -3 ﹪ RH
D thermal load: Many tested electronic products will be energized. Under the condition of power on, the tested product will generate heat, which will cause a load. So sometimes the equipment bought back, if the standard is -20 degrees, but the final temperature can not drop, this is the reason, so be sure to explain the load to the manufacturer
The refrigeration system of the high-temperature and high-humidity test chamber is an important part of the equipment. It is an important basis for judging the performance of a high-temperature and high-humidity test chamber. It includes four components: compressor, condenser, throttle device, and evaporator. The compressor is the heart of the refrigeration system. It sucks low-temperature and low-pressure gas into high-temperature and high-pressure gas, releases heat by condensing into a liquid, and then takes away the heat through the fan. This is the reason for the hot air under the high-temperature and high-humidity test chamber, followed by the evaporator. The low-temperature and low-pressure gas finally returns to the compressor; the refrigerant absorbs heat in the evaporator to complete the gasification process to absorb heat, achieve cooling purposes, and complete the high-temperature and high-humidity test chamber cooling process.
