An air conditioner outdoor unit refrigerant recovery and reuse device

Abstract

The invention discloses a refrigerant recovery and reuse device for an outdoor unit of an air conditioner, which includes a casing and a condenser pipe assembly, wherein the casing is a cylindrical cavity, and a plurality of condensation pipe assemblies are distributed on the inner circumference of the casing, each The refrigerant inlet and outlet of the condensing pipe assembly are respectively connected to the two general inlet and outlet interfaces by pipes. A centrifugal fan is arranged in the center of the cavity of the casing, and an air inlet is provided on the casing above the centrifugal fan. Compared with the prior art, in the present invention, when the condensing pipe assembly does not participate in the condensation work, the diversion grid rotates to close the gap, so that the spiral airflow generated by the centrifugal fan flows along the diversion grille to the condensation pipe participating in the condensation work The direction of the components is blown out, so that the utilization efficiency of the airflow is high, energy saving and environmental protection, the equipment works flexibly, it is suitable for air conditioners of different specifications, and it is small in size and easy to carry.

Description

technical field [0001] The invention relates to the technical field of refrigerant recovery, in particular to an air conditioner outdoor unit refrigerant recovery and reuse device. Background technique [0002] Refrigerant is the working fluid that completes the thermodynamic cycle in the refrigerator. It absorbs the heat of the cooled object at a low temperature, and then transfers it to cooling water or air at a higher temperature. In vapor compression refrigerators, refrigerants that can be liquefied at room temperature or lower temperatures are used as refrigerants, such as Freon, azeotropic mixed refrigerants, hydrocarbons, ammonia, etc. During disassembly and maintenance of refrigerants, it is necessary to Effective recovery of refrigerants, otherwise the discharge or leakage may pollute the environment, especially gases such as freon can also cause holes in the ozone layer. [0003] Refrigerant recovery equipment is used to recover refrigerants in refrigerators (ref...

AI Technical Summary

Problems solved by technology

Since the refrigerators for recovering refrigerant are mostly located outdoors, the staff needs to carry the recovery equipment to the workplace for recovery work. The existing condensing device is composed of a flat heat dissipation pipe and a fan, which often requires a large volume for heat dissipation and is not easy to carry. , especially in extreme environments such as high altitudes, the refrigerant can only be discharged into the air due to the inability to carry recovery equipment

[0004] In addition, the appropriate flow rate of refrigeration equipment of different specifications is often different when recovering refrigerant. For example, when the flow rate of refrigerant flowing into the recovery device is small, the air pressure is insufficient, so that the refrigerant cannot pass through the heat dissipation pipe smoothly, and the flow rate of refrigerant flowing into the recovery device is low. When the air pressure is too high, the condensation may not be complete, so it is necessary to choose different recovery devices according to different refrigerators, which increases the cost
