Title:
REFRIGERANT CONVEYING METHOD AND APPARATUS, AND REFRIGERANT PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/185095
Kind Code:
A1
Abstract:
The embodiments of the present invention relate to the technical field of automobile intelligent control. Disclosed is a refrigerant conveying method, which is applied to a refrigerant processing device. The method comprises: firstly, controlling a refrigerant to be conveyed between an automobile air conditioner and a refrigerant processing device through a first pipeline, and measuring a change in the weight of the refrigerant in the refrigerant processing device; when the change in the weight of the refrigerant reaches a first threshold value, switching the refrigerant to a second pipeline for conveying; then acquiring an environment heat temperature and a refrigerating effect temperature in the automobile air conditioner; and according to a comparison result of the environment heat temperature and the refrigerating effect temperature, controlling the amount of the refrigerant conveyed between the automobile air conditioner and the refrigerant processing device. The refrigerant conveying method provided in the embodiments of the present invention can convey a refrigerant with high precision and high efficiency.
