New energy automotive air conditioning system with rapid defrosting and demisting functions

Abstract

The invention discloses a new energy automotive air conditioning system with rapid defrosting and demisting functions. The system is characterized by being mainly composed of an interior heat exchanger side primary temperature rise and heat increase subsystem, a compressor side secondary temperature rise and heat increase subsystem, an exterior heat exchanger side third-stage temperature rise and heat increase subsystem, a power device composite heat recovery subsystem, a decompression expansion mechanism, auxiliary equipment, a connecting pipeline and the like. According to the new energy automotive air conditioning system with the rapid defrosting and demisting functions, provided by the invention, due to a combination of three temperature rise and heat increase subsystems such as the interior heat exchanger side primary temperature rise and heat increase subsystem, the compressor side secondary temperature rise and heat increase subsystem and the compressor side secondary temperature rise and heat increase subsystem, the prominent problems that the exhaust temperature of the compressor is extremely high, the interior heat exchanger has thick frost and defrosting difficulty, the system heat supply capacity and efficiency are low and the system operating reliability is low during heat pump air-conditioning low-temperature operation and the like can be obviously solved.

Description

Technical field [0001] The invention relates to an air conditioning system for rapid defrosting and defogging, in particular to a new energy automobile air conditioning system with fast defrosting and defogging functions. Background technique [0002] With the development of new energy vehicle technology, the development of a heat pump type new energy vehicle air conditioning system with fast defrosting and defogging functions has become one of the key technologies that need to be resolved. The reason is that due to the lack of internal combustion engines, heating in winter is greatly affected. Large restrictions, especially when the outdoor air temperature is very low, the developed heat pump type new energy vehicle air conditioning system cannot work normally, and thick frost is easily formed on the side of the heat exchanger outside the vehicle. The traditional reverse defrost method is adopted. At times, it has the disadvantages of long defrosting time, high power consumption...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a new energy vehicle air-conditioning system with fast defrosting and defogging functions, so as to solve the problem of thick frost on the external heat exchanger of the current common electric vehicle air-conditioning system when the outdoor temperature is too low Frost is harder, so that the entire system does not work properly with outstanding problems
