Abstract

The invention discloses a refrigeration system, and a method and a device for automatically filling the refrigeration system with refrigerants. The method for automatically filling the refrigeration system with the refrigerants comprises the following steps: S10, detecting ambient temperature T1, and acquiring the current lowest set pressure value Ps of the refrigeration system according to the ambient temperature T1; S20, detecting a system pressure value P1 of the refrigeration system, and judging whether the system pressure value P1 is smaller than or equal to the lowest set pressure value Ps; S30, if judging that the system pressure value P1 is smaller than or equal to the lowest set pressure value Ps, controlling an electromagnetic valve to be started so as to fill the refrigeration system with the refrigerants through a refrigerant filling pipe. According to the method, automatic refrigerant filling of the refrigeration system can be realized, so that two hands of a worker are free, and the automation degree is high.

Description

technical field [0001] The invention relates to the field of refrigeration, in particular to a method for automatically filling refrigerant in a refrigeration system, a device for automatically filling refrigerant in a refrigeration system, and a refrigeration system. Background technique [0002] In the related art, after the refrigeration system is assembled, if you want to add refrigerant to the system piping, the current processing method is to manually add after calculating the diameter and length of the piping, which is cumbersome and complicated for workers , handling is inconvenient. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, the present invention needs to propose a method for automatically filling the refrigerant in the refrigeration system, which can realize the automatic charging of the refrigerant in the refrigeration system, thus liberat...
