Air conditioning system filling parameter acquiring method and device

Abstract

The invention relates to the technical field of air conditioner filling, in particular to an air conditioning system filling parameter acquiring method and device. The method comprises the following steps that vacuum sensors and pressure sensors are arranged at joints and filling valves of air conditioning system pipelines; filling is carried out on multiple air conditioning systems separately through a quantitative filling method, and maximum pressure values and minimum pressure values of filling of the air conditioning systems are acquired; and normal distribution is performed on the acquired plurality of maximum pressure values and minimum pressure values separately, the filling pressure range is acquired, and the corresponding filling time range is acquired. According to the method anddevice, the reliable data support is provided for the early-stage filling process verification, repeated testing is avoided, and the parameter correcting time is saved.

Description

technical field [0001] The invention relates to the technical field of air-conditioning filling, in particular to a method and a device for obtaining filling parameters of an air-conditioning system. Background technique [0002] Vehicles have higher and higher requirements for the comfort and automation of the riding environment, and the air conditioning system plays a vital role in ensuring the comfort of the riding environment and driving safety. The refrigerant filling of the whole vehicle generally adopts the vacuum pressure filling method, and the vacuum degree and filling pressure become the key control parameters in the filling process. The whole vehicle filling process is divided into vacuum pumping and pressure filling process. Vacuuming is divided into primary vacuum, leak detection vacuum, and secondary vacuum. Primary vacuum is used to detect whether there is medium leakage or large leakage in the air conditioning system. Leak detection vacuum is used to detect...

Problems solved by technology

It takes a long time to modify the parameters, the effect is not significant and affects the cooling effect of the vehicle air conditioning system

However, due to the lack of standard filling parameters, the key dimensions of the existing pipeline design structure and the design of pipeline direction can only come from reverse engineering, and it is impossible to grasp the means of forward development of air conditioning pipelines.
