The invention provides an air conditioner heat pump system with functions of air make-up enthalpy increase and battery heat management. The air conditioner heat pump system comprises a compressor provided with a refrigerating output end, a heating output end, a main input end and an air make-up input end. A refrigerating loop is arranged between the refrigerating output end and the main input end.An indoor heat exchanger is arranged in the refrigerating loop and is connected with a third heat exchanger in a battery heat management loop in parallel. A fourth solenoid valve is arranged betweenthe indoor heat exchanger and the third heat exchanger. A heating loop is arranged between the heating output end and the main input end. A third heat exchanger is arranged at the input end of the heating loop. A first heat exchanger is arranged in the heating loop and is connected with the battery heat management loop through a seventh solenoid valve in parallel. The part, located between the first heat exchanger and the main input end, of the heating loop is connected with the battery heat management loop in parallel. An air make-up enthalpy increase loop is connected with the first heat exchanger and the third heat exchanger in series. According to the air conditioner heat pump system, the requirements for electric automobiles and battery packs for refrigerating and heating can be met at the same time, normal heating of the electric automobiles can be guaranteed in the low temperature environment, and energy consumption can be reduced.
Description
technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to an air-conditioning heat pump system with functions of supplementing air to increase enthalpy and battery heat management. Background technique [0002] At present, electric vehicle heating mainly uses PTC material heating technology, but its energy consumption is high, which has a great impact on the endurance of the vehicle. Therefore, this technology is not the most effective solution. The air source heat pump air conditioning unit has the advantages of simple system, energy saving and environmental protection, and convenient maintenance, so it has been widely promoted and applied. However, if the traditional air source heat pump air conditioner unit is used for heating in cold and humid areas in winter, when the outside temperature is very low, the heat decay of the system will be very fast, resulting in insufficient heating capacity. [0003] In additi...
