Abstract

The invention relates to a refrigerant filling system and method and an air-conditioning machine set. The refrigerant filling system comprises a refrigerant detection device and a refrigerant filling device, wherein the refrigerant detection device is used for detecting the parameter of a refrigerant circulation system and used for judging whether the parameters of the refrigerant circulation system meet preset judgment conditions or not; if the preset judgment conditions are met, a refrigerant is filled into the refrigerant circulation system through the refrigerant filling device. By adopting the refrigerant filling system provided by the invention, the refrigerant can be filled through the refrigerant filling device under the condition that the refrigerant detection device detects that the refrigerant is in shortage, a part of procedures of manually filling the refrigerant can be canceled, and thus the cost is lowered.

Description

technical field [0001] The invention relates to the field of refrigeration, in particular to a refrigerant filling system, method and air conditioning unit. Background technique [0002] At present, commercial air-conditioning systems with variable refrigerant flow in the market, such as frequency conversion multi-split units, unit units, etc., after the product engineering installation, the addition of pipeline refrigerant, especially the addition of system refrigerant after after-sales maintenance, is based on the commissioning personnel or maintenance personnel. Judging by empirical data or manually calculating the amount of refrigerant for filling. [0003] Due to the complexity of the project, the length of the pipeline is difficult to calculate accurately, and the professional level of the installation, commissioning and maintenance personnel is different. In addition, it is difficult to accurately judge the amount of refrigerant required after the after-sales maintena...
