Novel battery-electric-vehicle air-conditioning system

Abstract

The invention discloses a novel battery-electric-vehicle air-conditioning system. The novel battery-electric-vehicle air-conditioning system mainly comprises a vapor compression cycle part and a condensate liquid cycle part, wherein the vapor compression cycle part is composed of an evaporator, a compressor, an air cooling device and an electronic expansion valve; the condensate liquid cycle partis composed of a liquid collecting device, a liquid storage box, a contamination discharging valve, a filter, a connecting pipe, an atomizer and draught fans. The novel battery-electric-vehicle air-conditioning system is characterized in that the liquid collecting device is installed under the evaporator, and can collect condensate water on the surface of the evaporator; the atomizer is installedin the middle of the draught fans and the air cooling device, and can evenly spray condensate liquid collected by the liquid collecting device to the surface of the air cooling device, pressure of thehigh-pressure side of the air-conditioning system is reduced, and power dissipation of the compressor is reduced; the filter is installed the end, close to the liquid storage box, of the connecting pipe, and blocking of the atomizer can be prevented; the contamination discharging valve is installed at the lower end of the liquid storage box, and sludge of the bottom of the liquid storage box canbe discharged out in time. A cooling agent used in the novel battery-electric-vehicle air-conditioning system is CO2, and compared with a traditional air-conditioning system, the novel battery-electric-vehicle air-conditioning system is small in power consumption, high in refrigeration coefficient and free of pollution on the environment.

Description

technical field

[0001] The invention relates to the field of automobile air conditioning, in particular to a novel pure electric automobile air conditioning system. Background technique

[0002] Traditional fuel vehicles consume a large amount of fossil fuels every year, and at the same time emit a large amount of pollutants, causing serious environmental pollution problems, such as: global warming, ozone layer depletion, PM2.5, etc. For this reason, governments of various countries are vigorously developing pure electric vehicles, expecting to alleviate these environmental pollution problems.

[0003] In order to improve the comfort of pure electric vehicles during operation in summer, the interior of the vehicle is equipped with an air-conditioning system for regulating temperature and humidity. The refrigerant used in the air-conditioning systems of pure electric vehicles sold on the market today is R134a as the mainstream, and the air-conditioning type is mainly vapor c...

Examples

Embodiment Construction

[0016] The specific implementation manner of the new pure electric vehicle air conditioning system will be further described below in conjunction with the accompanying drawings.

[0017] The manufacturing process of the new pure electric vehicle air-conditioning system: Firstly, the compressor, air cooler, electronic expansion valve and evaporator are fixed on the corresponding positions of the pure electric vehicle, and connected in sequence, and the components are connected with copper tubes. Form a vapor compression cycle; then install the evaporator installed by the fan and the corresponding position of the air cooler; then connect the liquid collector, liquid storage tank, drain valve, connecting pipe and atomizer in sequence to form a condensate cycle; then filter Install the atomizer in the middle of the liquid storage tank, and install the liquid storage tank directly below the evaporator; then install the atomizer in the middle of the air cooler side fan and the air co...
