    • A vehicle air-conditioning system of a dual air-conditioner type exhibiting a hot gas heater function, which is designed to efficiently recover not only dormant refrigerant at the heater side, but also dormant refrigerant at the rear seat evaporator, which system sets the refrigeration cycle to a cooling mode and engages in a refrigerant recovery operation when starting up the heating mode by a hot gas heater cycle, then switches the refrigeration cycle to the heating mode, sets the front seat air-conditioning unit to the outside air mode at the time of the heating mode to blow outside air to the front seat evaporator by the front seat blower, then, when judging that the inside air temperature is high due to the refrigerant temperature of the rear seat evaporator at the time of the heating mode, operates the rear side blower to blow inside air to the rear seat evaporator.
    • 一种具有热气加热器功能的双重空调类型的车辆空调系统,其被设计成不仅有效地回收加热器侧的休眠制冷剂,而且还设置用于后座椅蒸发器的休眠制冷剂,该系统设定制冷 循环到冷却模式,并且通过热气体加热器循环启动加热模式时进行制冷剂回收操作,然后将制冷循环切换到加热模式,将前排座空调单元设置为外部空气模式 通过前排座鼓风机将外部空气吹送到前座椅蒸发器的加热模式的时间,然后,当在加热模式时判断由于后排座式蒸发器的制冷剂温度导致的内部空气温度高时, 后侧鼓风机将内部空气吹送到后座蒸发器。

    • In a refrigerant cycle system with a hot gas heater cycle, a pressure difference (&Dgr;Pd) between a high-pressure side refrigerant pressure of the hot gas heater cycle at a start of a heating mode and a high-pressure side refrigerant pressure of the hot gas heater cycle at a predetermined time after the start of the hot-gas heating mode is calculated. When the pressure difference (&Dgr;Pd) is in a predetermined range, it can be determined that the refrigerant is in a normal state. In this case, an electromagnetic clutch is turned on, and a compressor operates. On the other hand, when the pressure difference (&Dgr;Pd) is outside the predetermined range, it can be determined that the refrigerant is in a shortage state. In this case, the electromagnetic clutch is turned off, and the operation of the compressor is stopped.
    • 在具有热气体加热器循环的制冷剂循环系统中,在加热模式开始时热气体加热器循环的高压侧制冷剂压力与热的高压侧制冷剂压力之间的压力差(DeltaPd) 计算热气体加热模式开始之后的预定时间的气体加热器循环。 当压差(DeltaPd)在预定范围内时,可以确定制冷剂处于正常状态。 在这种情况下,电磁离合器接通,压缩机运转。 另一方面,当压力差(DeltaPd)在预定范围之外时,可以确定制冷剂处于短缺状态。 在这种情况下,电磁离合器被关闭,压缩机的运转停止。

    • 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。
