What is the Basic Working Principle of Drying Heat Pumps?

What is the Basic Working Principle of Drying Heat Pumps?

High temperature drying heat pump consists of an evaporator with fins, a compressor, condenser and expansion valves. Refrigerant constantly absorbs heat from the air and gets compressed, condensed, throttled and evaporates again. These procedures combine a whole circle. Inside the compressor, the pressure and temperature of refrigerant goes up (as high as 100℃).Then it releases its heat to the drying chamber to heat the air. At the same time it turns into fluid and absorbs heat again in the evaporator. It becomes gas and is ready to enter the next circle.

Wotech produces drying heat pumps suitable for food, slaughter, chemistry, etc. industries. For more please click www.wotech.cn and contact by export3@wotech.cn.
