Heat Exchangers In The Refrigeration Unit

Heat exchangers are essential elements in refrigeration systems. A heat exchanger is an energy (heat) exchange system between a hot and a cold fluid. On the other hand, during heating, exchangers are used as refrigerant condensers to discharge energy. In some refrigeration cycles, depending on the application, it is necessary to superheat or supercool the refrigerant. In refrigeration circuits, during cooling heat exchangers are used as evaporator, to absorb energy from the refrigerant.
