The Three Major Capabilities of a Walk-in Chamber

Walk-in chamber is an essential testing equipment in the field of aviation, automotive, home appliances, scientific research, etc., used to test and determine the parameters and performance of electrical, electronic, and other products and materials after temperature environment changes such as high temperature, low temperature, humidity or constant test. Here are the major capabilities of the walk-in chamber that we will explain to you:

The heating capacity of the walk-in chamber

The heating device is a key part of controlling the small walk-in chamber.

When the controller receives the heating instruction, it outputs voltage to the solid-state relay, about 3-12 volts DC, and the AC end is equivalent to connecting the wire, and the contactor also contracts at the same time. The heating element generates heat, which is circulated by the fan and brought into the walk-in chamber to raise the temperature of the chamber.

When the temperature reaches your set value, the controller regulates the solid-state relay by switching on and off.

We adjust the heating power by checking the outflow of the walk-in chamber screen, which controls the temperature above 89℃.

How to stabilize the temperature below 89 degrees? The walk-in chamber controls the heating power through the solid-state relay on one side and cools through the compressor cycle to achieve dynamic balance and maintain a constant temperature.

The cooling capacity of the walk-in chamber

It is an important parameter to judge the performance of a walk-in chamber. It includes four major components: compressor, condenser, throttling device, and evaporator.

The compressor is the heart of the refrigeration system. It sucks in low-temperature and low-pressure gas, which becomes high-temperature and high-pressure gas and is then condensed into a liquid and the heat is dissipated through the fan. Therefore, hot air is caused by the equipment below, then throttled into low-pressure liquid, and the evaporator becomes low-temperature and low-pressure gas, eventually returning to the compressor. The refrigerant absorbs heat in the evaporator to complete the vaporization process and absorbs heat to achieve the refrigeration purpose and complete the cooling process.

The humidifying and dehumidifying capacity of the walk-in chamber

The dehumidification system is also completed by the refrigeration system. The evaporator is placed inside the small walk-in chamber, which is relatively cold. The high-humidity gas in the chamber condenses into liquid when it encounters a cold object. In this way, the high-humidity gas in the chamber will decrease, achieving the purpose of dehumidification.
