The CEMS condenser unit is usually a component of a large system and is used to cool the environment through the evaporation and condensation of fluids. In these systems, cold fluid (usually a refrigerant) enters the compressor, and the compressor increases the temperature through compression. Then enter the cems condenser section, dissipate the heat to the external environment, and convert it into liquid. After removing the uncondensed particles in the dryer or collector, the fluid enters the expansion joint, releasing the pressure and allowing it to cool. Finally, the fluid enters the evaporator, which collects heat from the target environment (the area being cooled) to evaporate the fluid and send it back to the compressor as a gas. Condensing units are used in all types of heating, ventilation, and air conditioning (HVAC) systems. They can be purchased as a stand-alone cooling unit or just as a component of a large HVAC system.
