Embodiment 1

[0021] A heat pump air-conditioning system for an electric vehicle provided by the present invention is a dual-purpose vehicle air-conditioning system, such as figure 1 , figure 2 As shown, the electric scroll compressor 1 with the function of increasing enthalpy by gas injection is selected, and two heat exchangers are respectively arranged inside and outside the cabin, that is, the outside condenser 6 and the outside subcooler 7, the inside evaporator 9 and the inside Condenser 8. The in-vehicle evaporator 9, the in-vehicle condenser 8, and the in-vehicle air-conditioning fan 10 are placed together in a housing 12, integrated into an air-conditioning box assembly, arranged in sequence: outdoor fresh air inlet 13 and in-vehicle circulating air inlet 14, Adjust damper 11, air-conditioning fan 10, air-conditioning evaporator 9, interior condenser 8, defogging damper 15, head air outlet 16 and foot air outlet 17. The front end of the evaporator 9 in the car is provided with a...

Embodiment 2

[0030] In this embodiment, the scroll compressor 1 can be replaced by other types of compressors with gas injection to increase enthalpy.

[0031] The electronic expansion valve 28, the second temperature sensor 29 and the third temperature sensor 30 at the inlet and outlet of the gas circuit of the gas injection enthalpy increasing economizer 27 can also be replaced by electromagnetic valves and thermal expansion valves. That is, the electronic expansion valve 28 is replaced by the solenoid valve and the thermal expansion valve in series, and the second temperature sensor 29 and the third temperature sensor 30 are canceled at the same time.

[0032]The first solenoid valve 2 and the second solenoid valve 3 can also be replaced by an electric three-way valve or four-way valve, and the third solenoid valve 20 and the fourth solenoid valve 21 can also be replaced by an electric three-way valve or four-way valve.

[0033] In actual production, the exterior condenser 6 and the ext...

Abstract

The invention discloses an electronic automobile heat pump air-conditioning system which comprises a compressor with enhanced vapor injection, wherein the discharge hole of the compressor with enhanced vapor injection is divided into two paths; one path is connected with an inlet of a condenser outside an automobile; the other path is connected with an inlet of a condenser inside the automobile. By adopting the air-conditioning system disclosed by the invention, due to the compressor with enhanced vapor injection, COPs (Energy Efficiency Ratio) and cooling / heating quantities of the air-conditioning system can be increased in addition to cooling and heating functions, rapid cooling / heating can be achieved, the energy consumption of the air-conditioning system can be reduced by about 10-15%when being compared with that of a conventional air-conditioning system without enhanced vapor injection, the energy consumption of the air-conditioning system can be reduced by about 50% or greater when being compared with conventional PTC (Positive Temperature Coefficient) electric heating, and the endurance mileages of an electronic automobile can be increased.

Description

technical field [0001] The invention relates to a heat pump air-conditioning system for an electric vehicle, which belongs to the technical field of automobile air-conditioning. Background technique [0002] With the increasing shortage of environmental pollution and oil resources, the development of traditional fuel vehicles is increasingly restricted, and new electric vehicles are currently the most promising alternative. [0003] Electric vehicles have developed into one of the important road vehicles. Compared with ordinary internal combustion engine vehicles, the power source of the compressor of the air-conditioning system and the way of heating in winter are fundamentally different. For the existing air-conditioning system of electric vehicles, the air-conditioning system using ordinary electric compressors also has its limitations: electric vehicles have no engine waste heat, and the refrigeration system only operates in summer to meet the requirements of cooling the...
