Description

Technical Field

[0001] The invention relates to the technical field of refrigerant charging, and in particular to a refrigerant charging and discharging device for refrigeration equipment. Background Art

[0002] A refrigerator is a machine that transfers the heat of a cooled object with a lower temperature to the ambient medium to obtain cooling capacity. The heat transferred from the lower temperature object is usually called cooling capacity. The working fluid that participates in the thermodynamic process changes (energy conversion and heat transfer) in the refrigerator is called refrigerant. The refrigeration temperature range is usually above 120K, and below 120K belongs to the deep low temperature technology range. Refrigerator is widely used in industrial and agricultural production and daily life. Refrigerant recovery and filling machines can recycle the refrigerant in the refrigerator into the equipment, and after purification, it can meet the standards for reuse. The refrigerant in the refrigerator also has a certain use cycle. When the two substances do not meet the use standards, they need to be maintained and replaced.

[0003] Existing refrigerators are often filled with refrigerant through filling equipment. As the refrigerant is used for a long time, it undergoes oxidation reaction with metals and water in the system to generate sludge and impurities. When some parts in the refrigerator are damaged, a large amount of impurities will also be generated, so that the discharged refrigerant contains impurities and needs to be processed before it can be reused. In order to address the deficiencies of the prior art, we propose a refrigerant filling and discharging device for refrigeration equipment. Summary of the invention
