Heat pump air-conditioning system, control method thereof and vehicle

Abstract

The invention provides a heat pump air-conditioning system, a control method thereof and a vehicle. The heat pump air-conditioning system comprises a compressor, an outer-side heat exchanger, a firstinner-side heat exchanger and a second inner-side heat exchanger, the first inner-side heat exchanger can conduct heat absorbing and refrigerating on the interior of the vehicle, and the second inner-side heat exchanger can conduct heat release and heating on the interior of the vehicle; the heat pump air-conditioning system further comprises a first cooling loop, a cell box body and a third heatexchanger are arranged on the first cooling loop, and the third heat exchanger can be parallelly arranged at the two ends of the first inner-side heat exchanger; the third heat exchanger can also be parallelly arranged at the two ends of the second inner-side heat exchanger. According to the heat pump air-conditioning system, through a refrigerating agent, a cell can be refrigerated and cooled; the cell can also be heated and warmed through the refrigerating agent, thus the cell is cooled or heated as required, the requirement for temperature control over the cell is met, and it can be guaranteed that all main parts, particularly the cell of the electric vehicle can efficiently and reliably run while the requirement for the comfort of internal space inside a compartment can be met.

Description

Technical field [0001] The invention belongs to the technical field of air conditioning, and specifically relates to a heat pump air conditioning system, a control method thereof, and an automobile. Background technique [0002] At present, electric vehicles need more space and components for thermal management. The internal space of the car needs to be cooled or heated according to the needs of users. The drive motor and control module need to be dissipated to prevent high-temperature operation damage. The battery pack needs to be maintained at the best Operating temperature to ensure its work efficiency and life. At present, electric-driven air conditioners are generally used to adjust the temperature of the interior space of the vehicle compartment, and the driving motor, battery pack, control module, etc., use coolant or air cooling for heat dissipation. As pure electric vehicles have higher and higher requirements for cruising range, the energy density of lithium batteries ...
