Refrigeration & Air-Conditioning

Refrigeration and air-conditioning (RAC) is a specialized field whose basic principles include a refrigerant compressor, condenser, expansion valve, and evaporator. Any mechanical refrigeration system must have these four elements. Refrigeration is an industry that manufactures items lower than the outside temperature to keep them for a long time, including freezing, refrigeration, freezing, rapid freezing, and ultra-low temperature engineering. while air conditioning is to deal with the temperature, humidity, clean air distribution, and noise of the air and create a comfortable environment suitable for human life and work.
