What is a heat exchanger used for?
A. It boils off liquid refrigerant to prevent flooding the compressor.
B. It subcools liquid to prevent flash gas before the TEV.
C. It keeps the suction pressure up to the compressor.
Answer (2)
Heat exchangers are essential components in engineering, used for transferring heat between different fluids. They serve multiple functions, including boiling refrigerants, subcooling liquids, and maintaining suction pressure. Their efficiency is crucial for the optimal performance of HVAC and refrigeration systems. ;
Heat exchangers are important devices used to transfer heat between fluids without mixing them. Their key functions include boiling off liquid refrigerant to prevent compressor flooding, subcooling refrigerant before it enters the thermal expansion valve, and maintaining proper suction pressure. The correct choice from the options provided is B: It subcools liquid to prevent flash gas before the TEV.
