Ternary-cycle-typed new energy automobile air conditioning system

Abstract

The invention discloses a ternary-cycle-typed new energy automobile air conditioning system mainly consisting of a ternary-cycle shared compressor module I, a ternary-cycle shared auxiliary equipment module II, a vehicle exterior multifunctional composite module III with functions of evaporation, condensation, defrosting and the like, a vehicle interior multifunctional composite module IV with functions of cooling, heating, defrosting, defogging and the like, a ternary-cycle switching control, connecting pipes and the like. The ternary-cycle-typed new energy automobile air conditioning system can achieve three independent cycle forms which are the vehicle interior a heating and cooling two-way heat pump cycle, a quick defrosting self-circulation of a vehicle exterior heat exchanger and a quick defrosting and defogging self-circulation of vehicle interior windows according to the actual needs for the operation of a new energy automobile.

Description

technical field [0001] The invention belongs to the technical field of automobile air conditioning, and in particular relates to a three-cycle new energy automobile air conditioning system. According to the actual needs of the operation of new energy vehicles, the system can realize three independent circulation forms: two-way heat pump circulation for heating and cooling in the vehicle compartment, rapid defrosting self-circulation of the external heat exchanger, and rapid defrosting and defogging self-circulation of the interior windows. , It is very important for the comfort of passengers and the safe driving of the car. Background technique [0002] With the development of electric vehicle technology, electric vehicle air conditioners are becoming more and more restrictive to its development. Especially in recent years, the emergence of the energy crisis and the continuous improvement of environmental awareness have posed new and more severe challenges to the performanc...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a three-cycle new energy vehicle air-conditioning system to solve the problem that the current passenger car air-conditioning system cannot achieve a stable heat pump heating cycle when the outdoor temperature is too low in winter and cannot achieve stability when the outdoor temperature is too high in summer. Refrigeration cycle and external heat exchanger are prone to frosting and defrosting in winter, resulting in the failure of the entire air-conditioning system to work normally, and it is difficult to achieve rapid defrosting and defogging of the window glass, which seriously affects driving safety and other prominent problems
