The liquid chiller module is the core of the variable speed, vapor-compression chiller system. When the small chiller unit is properly installed, it uses vapor compressor technology to cool a circulating coolant.  The compact cooling module forms the heart of a liquid refrigeration system consisting of a compressor, evaporator, condenser, drive board, and other electronic parts.  An additional pump, reservoir, and control signal are required.  The heart of the cooling system is the mini compressor. Today, the mini dc rotatory compressor is widely used by many small and portable cooling systems.

 

Vapor compression circulatory refrigeration is a process that uses phase change heat transfer.  In the refrigeration cycle system, the compressor absorbs low-temperature, low-pressure refrigerant vapor from the evaporator and raises it to high-temperature, high-pressure by reducing the volume of the vapor. This vapor enters the condenser where heat is removed to the cooling medium(such as water, air, etc.). The high-temperature, high-pressure liquid exists in the condenser and enters the throttling device, where it undergoes a pressure drop.  The low-temperature refrigerant coming out from the throttling device flows into the evaporator where it is exposed to the heat source.  The heat from the source boils off the refrigerant through phase change heat transfer and the low-temperature, low-pressure vapor then enters the compressor completing the cycle.
