Sleeve heat exchanger manufacturer introduces the difference between gas-liquid separation tank and storage tank　

The refrigeration storage tank and gas-liquid separation tank are important components of the air conditioning refrigeration system, each fulfilling their respective responsibilities and work details. The gas-liquid separation tank must be installed behind the evaporator before entering the compressor at low pressure to prevent liquid refrigerant from being sucked into the inlet of the compressor, thereby generating a liquid hammer and damaging the internal components of the compressor. The liquid storage tank must be installed behind the condenser and before the regulating valve.

The basic function of a gas-liquid separator in a heat pump or refrigeration system is to separate and store the liquid in the reflux pipe, and to regulate the flow rate to prevent liquid hammer in the compressor. Therefore, it can temporarily store excess refrigerant liquid and prevent excess refrigerant from flowing into the compressor crankcase and causing oil dilution. During the separation process, the cold refinery will also be separated and stored at the bottom. The outlet pipe and bottom of the gas-liquid separation tank will have an oil hole filter screen to allow the cold oil to return to the compressor, effectively avoiding oil shortage in the compressor. The gas-liquid separation tank adopts a U-shaped elbow design inside, and the U-shaped pipe is equipped with a protective net and small hole components to prevent foreign objects and dirt from affecting the operation of the separator.

The main function of the refrigerant storage tank in the refrigeration system is to store refrigerant. Storage tanks are generally divided into high-pressure circulation storage tanks and low-pressure circulation storage tanks. Storing liquid components in the refrigerant to avoid reducing the heat transfer area due to excessive accumulation of refrigerant in the condenser, effectively reducing the load on the condenser, and providing continuous refrigerant flow to the evaporator so that partially cooled refrigerant can be cooled back to a fully liquid state. It also serves as a liquid seal to prevent gas from entering the low-pressure compressor and generating liquid hammer. The hydraulic hammer mainly occurs in piston compressors. Due to the suction of refrigerant liquid (or lubricant) into the compressor, abnormal impact accidents occur.
