Pressure swing adsorption principle of adsorption dryer

Pressure swing adsorption (PSA for short) is a new gas separation technology. Taking adsorbent molecular sieve as an example, its principle is to separate the gas mixture by using the difference in the "adsorption" performance of molecular sieve on different gas molecules.

What's wrong with the freezer not cooling

There are four main reasons: the first is the lack of refrigerant and the compressor has problems; the second is the problem of the power cord of the freezer; the third is the frost in the evaporator of the freezer; the fourth is that the storage in the freezer is too full. Of course, no matter what the reason is, you should find a professional to help repair the loophole or add refrigerant.

Summary of features and failures of scroll compressors Deep analysis

The scroll compressor is a positive displacement compressor, and multiple compression chambers are formed by the meshing of the scroll rotor and the scroll stator. With the translation and rotation of the vortex rotator, the volume of each compression chamber continuously changes to achieve gas inhalation and compression.
