[0032] In operation, the gas-liquid mixed refrigerant enters the inside of the cylinder 1 through the liquid inlet pipe 12, then collides with the first baffle 14, and then flows out from the first through hole 15, collides with the second baffle 16 and the third baffle 17, and then flows out through the second through hole 18. After the collision, the liquid refrigerant is collected at the bottom of the cylinder 1, and then is discharged through the liquid outlet pipe 13. The gaseous refrigerant floats above the liquid refrigerant and is discharged from the liquid inlet pipe 12. Through the above structure, the refrigerant can be effectively guided to flow along the predetermined path, reducing the occurrence of short circuits or dead zones, and improving the operating efficiency of the entire system. As more and more refrigerant enters the cylinder 1, the liquid refrigerant at the bottom of the cylinder 1 will fluctuate violently. By providing the first through hole 15 on the first baffle 14, the liquid level fluctuation can be effectively reduced. The first baffle 14, the second baffle 16, and the third baffle 17 effectively increase the heat exchange area, so that the refrigerant can more fully exchange heat with the external medium inside the economizer, thereby improving the heat exchange efficiency. The flow of the refrigerant can be adjusted according to the working conditions. Hold the handle 22 and rotate it.

Through the above structure, the flow of the refrigerant can be effectively controlled, and the economizer can maintain the best operating state under different working conditions, reducing unnecessary energy loss and improving the energy efficiency of the refrigeration system. When too much refrigerant enters the cylinder 1, the liquid refrigerant may also flow out through the exhaust pipe 11. A filter screen 31 is provided on the top of the third baffle 17 to filter out the liquid refrigerant in the gas-liquid refrigerant. Through the above structure, the liquid refrigerant can be effectively prevented from flowing out through the exhaust pipe 11, reducing the damage to the downstream compressor, thereby improving the performance of the entire refrigeration system. After being filtered by the filter screen 31, the gaseous refrigerant may still contain a small amount of liquid droplets. The presence of liquid droplets may cause damage to the downstream compressor, pump, and other equipment. A demister 41 is installed near the exhaust pipe 11. The demister 41 processes the gaseous refrigerant to remove the liquid droplets contained in the gas. Through the above structure, the liquid droplets in the gas can be effectively removed, reducing the coverage of the heat transfer surface by the liquid droplets, thereby improving the heat transfer efficiency. At the same time, the erosion of the liquid droplets to the downstream compressor, pump, and other equipment is also reduced. When the ambient temperature is too high, the refrigeration effect of the refrigerant inside the economizer may be poor, increasing energy consumption. A heat preservation plate 5 is provided outside the economizer. Through the above structure, heat exchange between the economizer and the external environment can be effectively reduced, making the refrigeration effect of the refrigerant better, thereby reducing energy loss and improving the overall energy efficiency of the system. The economizer may produce noise during operation, which may affect the working environment. A soundproof board 6 is provided outside the economizer. Through the above structure, the noise generated during the operation of the economizer can be effectively reduced, improving the comfort of the working environment and reducing noise pollution. By reducing noise, the fatigue of the operator can also be reduced, improving work efficiency.Thus indirectly improve the energy efficiency of the refrigeration system, the economizer in the operation process may appear due to the vibration or the shaking caused by external force, set support leg 71 in the bottom of the economizer, through the above structure, can enhance the stability of the economizer in the operation process, reduce the shaking caused by vibration or external force, thereby improving the reliability and service life of the equipment.
