Embodiment Construction

[0027] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] Firstly, a brief description of the traditional automotive air conditioning system is required before describing the specific embodiments of the present invention in detail.

[0029] Please see figure 1 , figure 1 It is a structural schematic diagram of a traditional automotive air-conditioning system. Such as figure 1 As shown, the traditional automotive air conditioner achieves refrigeration through the following working cycle: the compressor X1 transports high-temperature and high-pressure gaseous refrigerant (such as R134a) to the outdoor heat exchanger X2, and the refrigerant releases heat in the outdoor heat exchanger X2. The high-temperature and high-pressure gaseous refrigerant turns into a medium-temperature and high-pressure liquid state, and then enters the liquid receiver X3, and then passes through...

Abstract

The invention relates to the field of automobile air conditioning systems, and discloses an electric automobile air conditioning system. The electric automobile air conditioning system comprises a compressor (1), an outdoor heat exchanger (2), an indoor heat exchanger (3) and a throttle valve (4), and further comprises a first check valve (10), a second check valve (11) and an indoor auxiliary heat exchanger (6), wherein the second check valve (11) is connected with the indoor auxiliary heat exchanger (6) in series and used for heating, and forms a heating branch circuit, the first check valve (10) is used for refrigeration and forms a refrigeration branch circuit, and the heating branch circuit is connected with the refrigeration branch circuit in parallel. The electric automobile air conditioning system is based on an existing refrigeration system of a traditional automobile air conditioner, and achieves refrigeration and heating functions. Compared with a traditional automobile air conditioning system, the indoor auxiliary heat exchanger is added on the electric automobile air conditioning system, and therefore the electric automobile air conditioning system can provide heating effects which meet requirements of people. Furthermore, the electric automobile air conditioning system has the advantages of being low in cost, reliable in performance, easy to popularize and use and the like.

Description

technical field [0001] The invention relates to the field of automobile air-conditioning systems, in particular to an electric automobile air-conditioning system. Background technique [0002] Traditional automotive air conditioners such as figure 1 As shown in the figure, cooling is realized through a circulation loop system composed of compressor X1, outdoor heat exchanger X2, liquid receiver X3, throttle valve X4, indoor heat exchanger X5, and compressor X1 connected in sequence, while heating is achieved through outdoor The loop system formed by the water side heat exchanger X6, the indoor water side heat exchanger X7 and intermediate components absorbs the waste heat of the engine to realize it. [0003] With the advancement of science and technology and the continuous development of the automobile industry, at present, the efficiency of automobile engines is getting higher and higher, which makes the waste heat that the engine can use to heat the interior of the car i...
