Fool-proof and mistake-proof method and system for air conditioner refrigerant filling and computer readable storage medium

Abstract

The invention provides an air conditioner refrigerant filling fool-proof and mistake-proof method and system and a computer readable storage medium, and the air conditioner refrigerant filling fool-proof and mistake-proof method comprises the steps that a vacuumizing pipeline vacuumizes a refrigerant pipe of an air conditioner for a first preset time T1, the vacuum degree of the refrigerant pipe is P1, the vacuum degree P1 of the refrigerant pipe is kept stable and lasts for a second preset time T2, judging whether the following conditions are met at the same time: T1 is more than or equal to 6 seconds and less than or equal to 180 seconds, and P1lt; and T2 is larger than or equal to 120 seconds, and if yes, it is determined that vacuumizing of the refrigerant pipe is qualified. According to the fool-proof and mistake-proof method for refrigerant filling of the air conditioner, data such as the first preset time T1 for vacuumizing the refrigerant pipe, the real-time vacuum degree P1 of the refrigerant pipe and the second preset time T2 for keeping the vacuum degree P1 of the refrigerant pipe stable are obtained, and whether vacuumizing is qualified or not is judged by combining multiple conditions, so that vacuumizing data are more accurate and reliable, and the working efficiency is improved. The vacuumizing qualification degree of the refrigerant pipe can be accurately guaranteed, the production quality of an air conditioner vacuumizing and filling procedure is improved, and then the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of quality control of air-conditioning production, in particular to a fool-proof and error-proof method for perfusion of air-conditioning refrigerant, a system for realizing the method, and a computer-readable storage medium. Background technique [0002] The perfusion machine and perfusion station are the core equipment in the production process of the outdoor unit of the air conditioner. The pumping and perfusion process is to remove the air and water in the condenser (refrigerant pipe) and then perfuse the refrigerant, which is an important factor affecting the overall production quality of the outdoor unit of the air conditioner. process. In the production of air conditioners, the types and weights of refrigerants that need to be poured into external units of different orders and models are also different, and the parameters of the pouring machine need to be changed from time to time. [0003] At presen...

AI Technical Summary

Problems solved by technology

[0003]At present, it is mainly based on whether the vacuum degree in the air conditioner condenser is up to standard to confirm whether the vacuum has been drawn, and the refrigerant is injected through the refrigerant injection amount set on the filling machine, and This single-condition judgment method is prone to misjudgment, and cannot accurately guarantee whether the vacuum is qualified or not, and whether the refrigerant filling data is accurate
