って駆。As shown in FIG. 1, the automotive air conditioning system includes a heating unit 1 that circulates cooling water from an ennon 100 and radiates the heat, a radiator 2 that cools engine cooling water, a fan 3 that blows air to the radiator, and an engine. The pump inside is the basic equipment for heating. The blower fan 3 is driven by a pulley and belt attached to the rotating shaft of the Ennon.

を冷却している。The heating unit 1 and the evaporator 7 are installed in a ventilation duct 8, and the passage through which the air flows is adjusted using several types of dampers 9, 1°, etc., and the air volume is controlled by the strength of the ventilation fan 11. making adjustments. In this conventional cooling system, during cooling, the refrigerant compressed by the compressor 4 releases heat and liquefies in the condenser 6, and when the refrigerant expands through the capillary tube 21 and enters the evaporator 7, it absorbs the heat of evaporation. It cools the air that comes into contact with the evaporator.

2, and a device that automatically controls the damper opening, the electromagnetic clutch on/off, the air volume, and the opening/closing of the pulp 14 and 15 as shown in FIG. ing. However, in the case of heating with conventional automotive air conditioning systems, hot air does not come out until the engine is started and the temperature of the engine cooling water rises. Therefore, in winter, there was a drawback that the car would have to be run for several minutes with its engine turned on to become warm.
本発明は、このような従来の冷暖房装置の欠点を除去し

下を招くことがないようにしたことにある。The purpose of the present invention is to eliminate these drawbacks of conventional air-conditioning systems and generate hot air in a short period of time (several tens of seconds). The object of the present invention is to improve the engine efficiency without causing a decrease in the fuel efficiency of the engine.
以下１本発明の一実施例につき図面を参照して説明する
。An embodiment of the present invention will be described below with reference to the drawings.
第３図には本発明の一実施例に係る自動車用冷暖房装置
が概略的に示されている。FIG. 3 schematically shows a heating and cooling system for an automobile according to an embodiment of the present invention.
この自動車用冷暖房装置は、圧縮機４と、エンジン冷却

送風する凝縮器６と、ダクト８内に配置された蒸発器７
と、凝縮器６と蒸発器７との役割を交換しヒートポンプ
動作を行なわせるための切換パルプ２０とを備えている
。This automotive air conditioning system includes a compressor 4, a condenser 6 placed near a radiator 2 for engine cooling water and blown by a radiator fan 3, and an evaporator 7 placed in a duct 8.
and a switching pulp 20 for exchanging the roles of the condenser 6 and evaporator 7 to perform heat pump operation.

ピラリーチューブ２１を通り、蒸発器の役割りをする凝
縮器６に入って周囲の空気から熱を吸収して気化する。According to this automotive air conditioning system, by switching the switching pulp 20, the refrigerant compressed by the compressor 4 flows to the evaporator 7, and since the evaporator 7 functions as a condenser, heat is transferred to the evaporator 7. discharge. Therefore, the temperature of the air that comes into contact with the evaporator 7 rises and becomes warm air. The refrigerant leaving the evaporator 7 passes through the capillary tube 21 and enters the condenser 6, which functions as an evaporator, where it absorbs heat from the surrounding air and vaporizes.
従って、この時は従来の冷房時に使用した凝縮器と蒸発
器の役割りが入れ替わり、暖房器として動作する。Therefore, at this time, the roles of the condenser and evaporator used in conventional cooling are switched, and the device operates as a heater.
このように、切換パルプ２０を冷媒配管系に設置しヒー

ンジンの動力が圧縮機４に伝達しなくなるように制御す
る。In this way, by installing the switching pulp 20 in the refrigerant piping system and performing a heat pump action, warm air can be obtained at the same time as the engine is started. However, since the compressor 4 becomes a load on the engine, fuel efficiency deteriorates, so it is not preferable to use the heat pump for long-term heating. Therefore, when the temperature of the engine cooling water exceeds a certain predetermined temperature, for example, 50°C, the water temperature sensor 22 detects the temperature and the controller 23 makes a judgment, and the electromagnetic clutch 5 is disengaged to transfer engine power to the compressor 4. control so that it is no longer transmitted.
更に、エンジン冷却水がちる所定温度、例えば６０℃以

ジェータでエンジン冷却水を冷却することは水温のよ昇
時間を長くするだけであり、エネルギーの損失となる。Furthermore, if the engine cooling water is at a certain temperature, for example 60°C or lower, the engine will not warm up sufficiently, and cooling the engine cooling water with a radiator in such cases will only lengthen the time it takes for the water temperature to rise. This results in a loss of energy.

２３からの信号によってラジェータファン３を止め。Furthermore, if the grille 16 is left open, the temperature will rise even more slowly since the outside air will significantly cool the vehicle while the vehicle is running. Therefore, when the temperature of the engine coolant is low, the radiator fan 3 is stopped by a signal from the control device 23.
グリルを閉じることによりエネルギーの損失を少なくす

、更に燃費の悪化を防ぐことができる。As explained above, according to the present invention, warm air is blown out at the same time as the engine is started, so it is possible to drive comfortably even in the cold winter. Furthermore, the temperature of the engine coolant can be detected, and when the temperature of the engine coolant rises, heating can be automatically switched to heating using heat released from the engine coolant, thereby preventing deterioration of fuel efficiency. Furthermore, when the temperature of the engine coolant is low, the radiator fan is stopped and the grill is closed, so the temperature of the engine coolant quickly rises, further preventing deterioration of fuel efficiency.
