Problems solved by technology

At present, the gas-liquid compound recovery method is mostly used to recover refrigerants. However, during the operation of this type of recovery equipment, liquid refrigerants and gaseous refrigerants are still recovered separately, and the switching time between the two is determined by the operator based on experience. Random control, which leads to failure to achieve the most reasonable recovery efficiency and recovery rate

Embodiment Construction

[0053] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0054] In addition, if there are descriptions related to "first", "second", etc. below, the descriptions of "first", "second", etc. are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance nature or implicitly indicate the number of technical characteristics indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of these features. In addition, the terms "comprising", "having" and any variations thereof are intended to cover a non-exclusive inclusion, for example, a process, method, system, product or device comprising a sequence of steps or elements is not necessarily limited to the explicitly listed instead, may include other steps or elements not explicitly listed or inherent to the process, met...

Abstract

The invention provides a refrigerant recovery system and a control method. The system includes: a recovered container, a compressor, a zoom nozzle, a mixing container, a condenser, and a recovery container; An outlet and the first inlet of the mixing container, and the compressor and the zoom nozzle are arranged in series on the first pipeline; the second pipeline communicates with the mixing outlet of the mixing container and the The recovery inlet of the recovery container, and the condenser is arranged on the second pipeline; the liquid recovery pipeline communicates with the second outlet of the recovered container and the second inlet of the mixing container. With the cooperation of the scaling nozzle and the mixing container, the present invention realizes the simultaneous recovery of the gas-liquid two-phase refrigerant, does not need to manually switch the recovery mode, simplifies the operation steps of the recovery system, effectively shortens the recovery time, and can reduce the number of compressors at the same time. The suction and exhaust volume can reduce the condensation load of the condenser.

Description

technical field [0001] The invention relates to the technical field of refrigerant recovery, in particular to a refrigerant recovery system and a control method. Background technique [0002] Due to the toxicity, combustion and explosiveness of the refrigerant itself, its corrosiveness to materials, and the reduction of the amount of ozone in the atmosphere, which will bring about the global warming effect, the refrigerant should not be discharged directly, and special recovery equipment is required for recycling. reuse. At present, the gas-liquid compound recovery method is mostly used to recover refrigerants. However, during the operation of this type of recovery equipment, liquid refrigerants and gaseous refrigerants are still recovered separately, and the switching time between the two is determined by the operator based on experience. Random control is carried out, which leads to the inability to achieve the most reasonable recovery efficiency and recovery rate. Cont...
