The invention relates to a new energy vehicle heat pump air conditioning system integrating three electric heat managements. The heat pump air conditioning system switches heat pump and air conditioner modes through a first normally closed electromagnetic valve and a second normally open electromagnetic valve, and forms a secondary loop through connection of a battery heat management system and amotor electric control heat management system; the battery heat management system forms a battery cooling unit loop by a chiller, a first secondary water tank, a first one-way valve, a battery liquidcooling plate, a water PTC, a second three-way valve and a first electric water pump connected in sequence; and the motor electric control heat management system forms a motor electric control coolingunit loop by a motor liquid cooling plate, an electric control liquid cooling plate, a first three-way valve, a low-temperature water tank, a second secondary water tank, a fourth electromagnetic valve, a battery liquid cooling plate, a sixth electromagnetic valve and a second electronic water pump connected in sequence. The new energy vehicle heat pump air conditioning system integrates the functions of passenger compartment heat management, batteries, motors and electric control heat management, provides a feasible scheme for vehicle heat management system development.
