Heating or cooling system for electric motor-driven vehicle, has electric drive motor and source of electrical energy for electric drive motor, where refrigerant circuit is equipped with compressor assembly

摘要

The heating or cooling system (10) has an electric drive motor and a source of electrical energy (40) for the electric drive motor. A refrigerant circuit (12) is equipped with a compressor assembly (14), where an expansion assembly (16,18) has a heat exchanger assembly (20) for transferring heat between a coolant and an air stream (L). The refrigerant circuit is operated in a heating mode and in a cooling mode.
