Problems solved by technology
[0006] However, the refrigerant compression device 6 of the conventional refrigerant recovery machine adopts a reciprocating compressor 61, which needs to increase the power and oil volume to start the operation, which not only occupies a large volume, but also has a heavy overall weight; and because Separators 63 and 65 are used to separate the refrigerant from the refrigerating machine oil, and it is difficult to achieve a high degree of purification of the refrigerant; in addition, conventional refrigerant recovery machines are designed to use a large number of solenoid valves to control the flow path to forcibly guide the refrigerant. The normally closed method of natural convection is not used to introduce the refrigerant into the refrigerating and air-conditioning body, so the cost of its components is high, and it is not economical
[0007] As mentioned above, in the manufacturing of the conventional refrigerant recovery machine, not only because the reciprocating compressor 61 occupies a large volume and is heavy, it cannot be light and easy to transport, but also because a large number of solenoid valves are used in assembly. Control for refrigerant recovery, filling, and vacuuming and other function switching, but cannot reduce manufacturing costs, so it is difficult to improve the overall economic benefits
Therefore, in the actual manufacture and use of conventional refrigerant recovery machines, there are still the above-mentioned deficiencies that need to be improved urgently.
