Abstract

This invention discloses a kind of motor vehicle air conditioner system. It includes power-supplying device, electric engine, refrigerating compressor, condenser, electronic expanding valve, evaporator, controller and temperature sensor. The said power-supplying device supplies power to electric engine, which drives the refrigerating compressor working. The said refrigerating compressor, condenser, electronic expanding valve and evaporator connect in turn to form refrigerating loop. The said controller positions between power supplying device and electric engine. The power-supplying device supplies power to electric engine through controller. The temperature sensor senses the temperature in the car and sends signal to the controller, which controls the rotating rate of electric engine. This invention can decrease energy consumption.

Description

【Technical field】 [0001] The invention relates to an automobile air-conditioning system and a control method, in particular to an electric vehicle air-conditioning system and a control method. 【Background technique】 [0002] Air-conditioning units are installed on typical cars these days. Chinese patent application No. 03140422.7 discloses a motor-driven automobile air conditioner, including a car body and an automobile engine installed on the car body, a cooling water tank, an engine pulley, a transmission belt, and a generator connected by the belt, a battery pack, and an electric motor. 1. Air conditioner compressor, the car air conditioner compressor is not driven by the car engine, but directly driven by the special motor connected to the battery pack to run the air conditioner compressor. Although the above-mentioned technology has changed the traditional use of the engine to drive the automobile air-conditioning compressor, and uses a special motor on the battery pac...
