The invention provides a carbon dioxide heat pump air conditioner control method and system.The method comprises the steps that when it is detected that a user starts a heating function, a carbon dioxide working medium is compressed into high-temperature and high-pressure carbon dioxide gas through a carbon dioxide compressor, and the carbon dioxide gas is conveyed into a first evaporative condenser; carbon dioxide gas is condensed into corresponding carbon dioxide liquid, and hot air is output into a cab in the vehicle; the carbon dioxide liquid flows through a heat exchanger and is conveyed into a second evaporative condenser, so that the carbon dioxide liquid is evaporated into corresponding low-temperature low-pressure carbon dioxide gas; and the low-temperature and low-pressure carbon dioxide gas sequentially flows through a gas-liquid separation tank and a heat exchanger, and the low-temperature and low-pressure carbon dioxide gas output by the heat exchanger is conveyed into a carbon dioxide compressor, so that the heating cycle of the cockpit is completed. The heating efficiency of the air conditioner can be greatly improved, and the use experience of a user is correspondingly improved.
本发明提供了一种二氧化碳热泵空调控制方法及系统,该方法包括:当检测到用户启用制热功能时,通过二氧化碳压缩机将二氧化碳工质压缩成高温高压的二氧化碳气体,并将二氧化碳气体传输至第一蒸发冷凝器中,以将二氧化碳气体冷凝成对应的二氧化碳液体并向车辆内部的驾驶舱中输出热风;将二氧化碳液体流经换热器并传输至第二蒸发冷凝器中,以将二氧化碳液体蒸发为对应的低温低压二氧化碳气体;将低温低压二氧化碳气体依次流经气液分离罐以及换热器,并将换热器输出的低温低压二氧化碳气体传输至二氧化碳压缩机中,以完成驾驶舱的制热循环。本申请能够大幅提升空调的制热效率,对应提升了用户的使用体验。
