Synchronous combined double-circulation new energy automobile air conditioning system

Abstract

The invention provides a synchronous combined double-circulation new energy automobile air conditioning system. The system is characterized by being mainly composed of a compressor combined module I, a combined double-circulation assistant module II, an automobile outside cold-heat combined module III, an automobile inside cold-heat combined module IV, a power system cooling heat recycling module V, a combined double-circulation function switching control module and corresponding pipelines. The system can form two heat power circulating systems which run relatively independent, and the heat power circulating systems which are relatively independent can be combined into synchronous double-circulation working modes of various forms like a synchronous double-refrigerating-circulation system, a synchronous double-heating-circulation system and a synchronous refrigerating and heating double-circulation system. By the system, efficient and reliable refrigerating or heating in an automobile is realized, and various functions like quick defrosting and demisting of windscreens, quick defrosting of a heat exchanger outside the automobile and recycling of heat of a power system can be realized.

Description

technical field [0001] The invention provides a synchronous composite double-cycle air-conditioning system for new energy vehicles. The system can constitute two relatively independent thermodynamic circulation systems, and the two independent thermodynamic circulation systems can synchronize dual refrigeration cycles, synchronous dual heating cycles, and synchronous refrigeration and heating rapid defrosting cycles of external heat exchangers according to actual needs , Synchronous cooling and heating, rapid defrosting and defogging cycle of windows and other working modes. Background technique [0002] In recent years, due to the emergence of the energy crisis and the continuous improvement of environmental protection awareness, new and more severe challenges have been posed to the improvement of the cooling and heating performance of automotive air conditioners. Therefore, whether to design a reasonable, efficient, practical, and economically feasible automotive air-cond...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a synchronous compound dual-cycle new energy vehicle air conditioning system to solve the problem of uninterrupted heat supply in the current winter ultra-low temperature environment while exchanging the outside of the vehicle for the above-mentioned shortcomings in the prior art. Problems such as defrosting of the heater surface, rapid defrosting and defogging of the car windows, and outstanding problems such as the air conditioning system cannot stabilize the refrigeration cycle caused by the high outdoor ambient temperature in summer
