Heat pump system, energy-saving control method of heat pump system and vehicle

Abstract

The invention provides a heat pump system, an energy-saving control method of the heat pump system and a vehicle. The problem that a vehicle heat pump system cannot meet the energy-saving and environment-friendly requirements is solved. The heat pump system comprises a main refrigerant loop, wherein a compressor, an internal condenser, a first electromagnetic valve, an external condenser, a first throttling device and an evaporator are mounted on the main refrigerant loop; a first refrigerant pipeline, wherein a second electromagnetic valve is arranged on the first refrigerant pipeline; a second refrigerant pipeline, wherein a heat exchange device and a second throttling device are arranged on the second refrigerant pipeline; a third refrigerant pipeline, wherein a third electromagnetic valve is arranged on the third refrigerant pipeline; a first cooling liquid pipeline, wherein a first suction device, a cooling liquid heating device and a three-way proportional valve are mounted on the first cooling liquid pipeline; a second cooling liquid pipeline, wherein a warm air core body is mounted on the second cooling liquid pipeline; a battery cooling pipeline, wherein second suction device, a power battery and a four-way valve are mounted on the battery cooling pipeline; and an electric driving pipeline, wherein an electric automobile vehicle-mounted charger, a third suction device, a high-voltage electric control module, a driving motor cooling device, a radiator and a third cooling liquid pipeline are arranged on the electric driving pipeline.

Description

Technical field [0001] The present invention relates to the field of vehicle air conditioning equipment, and more particularly to a heat-saving control method and a vehicle of a heat pump system, a heat pump system. Background technique [0002] With the gradual popularity of new energy vehicles, the energy saving and battery life of new energy vehicles have become key technologies that major host plants and related components suppliers need to solve. The air conditioner is used as a new energy in the new energy vehicle, and energy saving has also become an air conditioning system that cannot be escapable. Due to the low temperature heating scheme (PTC wind heating or PTC water heating), the heat pump air conditioner is less than half below half of the electric heating scheme (PTC wind or PTC water). In recent years, heat pump air conditioners have begun to become air conditioning energy conservation for major host plants in new energy owners. Among them, heat pump air conditioni...
