A heat exchanging process, in process of refrigerastion, necessarily leads to substantial amounts of waste heat, it is necessary to by there is air-cooled two kinds of form condensers of water cooling
Distribute, reduce compressor temperature.Common cooling-water machine is exactly that this partial heat is passed through cooling tower, fan or other forms
It is dispersed into air, wastes thermal energy and electric energy is more, in need then to want additional heat when using hot water and in practical application, wave
Take the energy, take a lot of work laborious.
