    • An air conditioning system for a vehicle has a plurality of heat enhancing means including at least a hot gas heater cycle for heating air blown into a passenger compartment by directly introducing a discharged gas refrigerant from a compressor into an interior heat exchanger. Additionally, an electric heater is provided as another passenger compartment heating enhancing means. When heat requirements are high (outside air temperature is low), both the hot gas heater cycle and the electric heater are activated, and when the heat requirements decrease, the hot gas heater cycle is deactivated first, and then the electric heater is deactivated. Therefore, the adverse effects of a vehicle compartment temperature that the driver is sensing can be avoided. Additionally, controlling vehicle window fogging associated with an operation of the hot gas heater cycle is possible.
    • 一种用于车辆的空调系统具有多个热增强装置,至少包括热气加热器循环,用于通过将排出的气体制冷剂从压缩机直接引入到内部热交换器中来加热吹入乘客室的空气。 另外,设置有电加热器作为另一乘客室加热增强装置。 当热量要求较高(室外空气温度低)时,热气加热器循环和电加热器都被激活,当热量要求降低时,首先停止热气加热器循环,然后电加热器停用。 因此,可以避免驾驶员感测到的车厢温度的不良影响。 此外,控制与热气体加热器循环的操作相关联的车窗雾化是可能的。
