The refrigerating / dehumidification system applies a set of Germany Bock semi-hermetic cascade compressors.

Refrigeration methods can be classified into vapor compression refrigeration, absorption refrigeration, steam jet refrigeration, gas expansion refrigeration and thermoelectric refrigeration. Above all, vapor compression refrigeration is the most widely used and economical refrigeration method, and also is the most commonly method used in environmental testing equipment. The principle is using Freon and other liquid evaporation as the medium which absorbs and removes heat to achieve refrigeration.

Single-Stage refrigeration cycle diagram is the schematic diagram of vapor compression refrigeration cycle process.
