[0002] With the development of economy, transportation industry, food industry and medicine industry are also developing day by day. The storage of transported goods or food and the preservation of medicine or medical samples require storage in cold storage. Large public buildings such as shopping malls or buildings also need energy-saving refrigeration units. A refrigerator is a machine that transfers the heat of a cooled object with a lower temperature to the ambient medium to obtain cooling capacity. The heat transferred from the object with a lower temperature is usually called cooling capacity. The working fluid participating in the change of thermodynamic process in the refrigerator is called refrigerant. The refrigeration unit is usually composed of a compressor, a condenser, an expansion valve, an evaporator and a control system. The condenser is a component for internal and external heat exchange in the refrigeration unit.
