Problems solved by technology

The above methods are complicated to operate, labor-intensive, cumbersome to operate, leak more, cause a lot of waste of refrigerant, increase maintenance costs, increase the burden on consumers, and also pollute the environment. In addition, inaccurate measurement seriously affects refrigeration. The life of the equipment, the old-fashioned equipment is unscientific, the use time cannot be long, and the compressor will be burned out if it is too long

Abstract

A digital quantitative refrigerant pumping-out and filling-in machine for manufacturing and repouring the refrigerator is composed of casing, air pumping-out and filling-in unit, and quantitative liquid pumping-out and filling-in unit. Its advantages is high precision, small size and light weight.

Description

technical field [0001] The invention relates to the technical field of refrigeration maintenance equipment, in particular to a digital refrigeration quantitative pumping and filling machine. Background technique [0002] In the manufacture and maintenance of refrigeration equipment, old-fashioned electronic scales are used to measure the amount of refrigerant for the extraction and filling of refrigeration equipment. Vacuum pumps are used to draw vacuum or fill refrigerant to empty, especially for maintenance of refrigeration equipment, such as: Air conditioners, refrigerators, freezers, etc. all use only one pressure gauge and one refrigeration tank to fill the refrigerant. The above methods are complicated to operate, labor-intensive, cumbersome to operate, leak more, cause a lot of waste of refrigerant, increase maintenance costs, increase the burden on consumers, and also pollute the environment. In addition, inaccurate measurement seriously affec...
