A liquid line and suction line heat exchanger are used to transfer heat between liquid refrigerant leaving the condenser on the high-pressure side of the system and refrigerant vapour leaving the evaporator on the low-pressure side of the system.
This heat transfer causes following effects
- To raise the vapour temperature (Superheating) to prevent frosting or condensation on the suction line
- To evaporate any remaining liquid in the vapour stream to prevent possible compressor damage
- To sub-cool the liquid to prevent flash gas in the liquid line
- To increase the system refrigerating capacity

A suction line liquid line heat exchanger causea)Subcooling of liquid ...
Subcooling of liquid refrigerant:
- A suction line liquid line heat exchanger can cause subcooling of liquid refrigerant entering the expansion device. This is because the heat exchanger removes heat from the refrigerant, lowering its temperature below its saturation point. Subcooled liquid refrigerant entering the expansion device can improve the overall efficiency of the refrigeration cycle.
Superheating of the suction vapour:
- The heat exchanger can also lead to superheating of the suction vapor. As the refrigerant absorbs heat from the surroundings in the heat exchanger, it can become superheated before entering the compressor. This can have implications for the performance of the system.
Possible impact on COP:
- The suction line liquid line heat exchanger may increase or decrease the Coefficient of Performance (COP) of the refrigeration system. The extent to which the COP is affected depends on various factors such as the design of the heat exchanger, operating conditions, and the specific characteristics of the refrigerant used.
Conclusion:
- In conclusion, a suction line liquid line heat exchanger can have multiple effects on the refrigeration system, including subcooling of liquid refrigerant, superheating of suction vapor, and potential changes in COP. It is essential to consider these factors when designing and operating refrigeration systems to ensure optimal performance.
