Problems solved by technology

However, since the air conditioner is placed on the electric bus, in the case of strong sunlight in summer, the power conversion device on the top of the electric vehicle generates a lot of heat due to sunlight and self-heating. The reliability of the components, when the temperature rises to a certain limit, the power supply device cannot work normally, and it is easy to cause damage in severe cases, affecting the driving of electric buses and causing inconvenience to transportation

Description

technical field [0001] The invention relates to an electric passenger car air conditioner, which is mainly used in the field of electric passenger cars. Background technique [0002] The traditional first-generation product belongs to the split air conditioner, which drives an open-type compressor and DC generator by a high-power DC motor. The compressor and DC generator are installed on the chassis of the electric bus, while the overhead air conditioner ( Condenser and evaporator assembly) are installed on the roof and connected by pipes in the middle. However, with the development of electric passenger cars towards low floors, it is no longer suitable to install compressors and accessories on the chassis, and it is impossible to install compressors and accessories on the roof because of the high height and weight. The refrigeration system has low efficiency and high energy consumption. Therefore, in response to this situation, an integrated top-mounted electric air condi...
