Abstract

The invention provides a heat pump air conditioning system of a vehicle and a control method thereof. The heat pump air conditioning system comprises an air conditioning heating and refrigerating loopformed by a compressor, a four-way valve, an outdoor heat exchanger, an indoor heat exchanger and the like through pipelines. The air conditioning system further comprises a heat accumulator, and heat generated by a power battery and / or an indoor motor and / or an outdoor motor is absorbed through the heat accumulator. The heat accumulator is used for deicing or defrosting an outdoor fan by using the absorbed heat and / or is used for deicing or defrosting an outdoor heat exchanger. By recycling heat generated by the indoor motor, the outdoor motor and the power battery, the heat melts ice and snow between fan blades of the outdoor fan and a flow guide ring, and the fan blades are prevented from being stuck and manual ice and snow removal procedures are avoided. Heat generated by the motor and the power battery can be used for defrosting the outdoor heat exchanger, and in-vehicle cooling and discomfort of a human body in the conventional defrosting process are avoided. The surface temperature of the power battery and the motor is reduced and the service life is prolonged.

Description

technical field [0001] The present invention relates to a heat pump air conditioning system and its control method, in particular to a vehicle heat pump air conditioning system and its control method. Background technique [0002] With the popularity of new energy electric buses, heat pump air conditioners for passenger cars are increasingly used in electric buses due to their high energy efficiency. Restricted by the structure of the heat pump air conditioner and electric bus, the heat pump air conditioner is usually placed on the top of the bus, and the condensing fan is exposed to the air. In winter in the north, when the bus is parked outside, the condensing fan will be covered by ice and snow, and the condensing fan blades will be stuck by the ice and snow. Therefore, when the air conditioner is turned on, the condensing fan cannot be started, which may cause the condensing motor to burn out, and the heat pump air conditioner cannot operate normally. . [0003] When t...
