Abstract

The invention provides a refrigerant amount judgment method and system, computer equipment and a computer readable storage medium. The refrigerant amount judgment method is used for an air conditioner. The air conditioner comprises an indoor unit and an outdoor unit. The air conditioner is filled with a refrigerant. The refrigerant amount judgment method comprises the steps that exhaust parametersof the outdoor unit are detected in a refrigeration mode, and the relation between the exhaust parameters and preset exhaust parameters is judged; and according to the judgment result, whether the refrigerant amount in the air conditioner reaches the standard refrigerant amount or not is judged. According to the provided refrigerant amount judgment method, whether the refrigerant amount in the air conditioner reaches the standard refrigerant amount or not can be determined by detecting the exhaust performance parameters of the outdoor unit in the refrigeration mode and comparing the detectedexhaust parameters with the preset exhaust parameters.

Description

technical field [0001] The present invention relates to the technical field of central air-conditioning, in particular to a method for judging the amount of refrigerant, a system for judging the amount of refrigerant, a computer device and a computer-readable storage medium. Background technique [0002] The accuracy of the amount of refrigerant in the air conditioning system plays a vital role in the safety, reliability and comfort of the system. Too little refrigerant charge will lead to high discharge temperature of the compressor, which will easily cause high-temperature failure of the lubricating oil and cause serious damage to the compressor. At the same time, the low amount of refrigerant in the system is the root cause of the insufficient cooling and heating capacity of the system, which in turn leads to unsatisfactory air conditioning effects and affects customer use. [0003] When charging the refrigerant to the multi-connected air-conditioning system, the diamete...
