Embodiment Construction
[0059] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0060] The refrigerant recovery device 10 is used to recover refrigerant, in other words, the refrigerant recovery device 10 is used to connect the recovered unit 11 to extract and recover the refrigerant in the recovered unit 11 .
[0061] Among them, such as figure 1 , the refrigerant recovery device 10 includes a first refrigerant recovery branch 12 and a second refrigerant recovery branch 13 . One end of the first refrigerant recovery branch 12 is connected to the recovered unit 11 , and the other end is connected to the recovery container 16 . A compressor 121, a Laval nozzle 122, a heat exchanger 123, and a first solenoid valve 124 are sequentially arranged on the first refrigerant recovery branch 12. During the recovery process of ...

The invention provides a refrigerant recovery method, a control device and a refrigerant recovery device, and relates to the technical field of refrigerant recovery. The refrigerant recovery method is applied to the refrigerant recovery device, the refrigerant recovery device comprises a first refrigerant recovery branch, one end of the first refrigerant recovery branch is connected to a recovered unit, the other end of the first refrigerant recovery branch is connected to a recovery container, and a compressor is arranged on the first refrigerant recovery branch. The method comprises the steps that the compressor is controlled to increase or decrease the operation frequency according to a compressor top shell temperature value and a first preset temperature value, so that the compressor top shell temperature is controlled to approach the first preset temperature value. The refrigerant recovery control device and the refrigerant recovery device provided by the invention can execute the refrigerant recovery method. According to the refrigerant recovery method, the control device and the refrigerant recovery device provided by the invention, the technical problem of excessive energy consumption caused by improvement of the refrigerant recovery efficiency in the prior art can be improved.
Description
technical field [0001] The invention relates to the technical field of refrigerant recovery, in particular to a refrigerant recovery method, a control device and a refrigerant recovery device. Background technique [0002] The application and development of refrigerant recovery equipment is slow. In addition to the lack of awareness of environmental protection among practitioners, another important reason is that many refrigerant recovery equipment currently have various defects such as low recovery speed and efficiency in the actual application process, and Recycling equipment with a relatively fast recovery speed has problems such as relatively large volume and inconvenient transportation, but some small and portable equipment have relatively slow recovery speed. [0003] In the prior art, in order to improve the recovery efficiency of the refrigerant, generally only the method of increasing the operating frequency of the compressor is adopted, but when the operating frequ...
