If the temperature is around C, it will take about 5 to 15 minutes, and if the outside air is around -2O3C, it will take about 20 to 30 minutes. Therefore, conventional car heaters have the disadvantage that occupants feel cold while the engine warms up.
それ故に、本発明の課題は、いちはやく車室の暖房を可

［作用］
水冷式エンジンが暖まっている場合、この水冷式エンジ
ンを通過して暖められた冷却水は、蓄熱熱交換装置を通
過する際に、主蓄熱材及び温度保障蓄熱材を加熱する。[Operation] When the water-cooled engine is warm, the coolant that has passed through the water-cooled engine and been warmed heats the main heat storage material and the temperature-guaranteed heat storage material when passing through the thermal storage heat exchange device.
これらの蓄熱材に封入された蓄熱剤は、加熱されると固
相から液相に変わり、潜熱の形で蓄熱する。When the heat storage agent enclosed in these heat storage materials is heated, it changes from a solid phase to a liquid phase and stores heat in the form of latent heat.
水冷式エンジンを停止させると、主蓄熱材及び温度保障
蓄熱材は、自然放熱によりその温度を下げる。When the water-cooled engine is stopped, the temperature of the main heat storage material and the temperature guaranteed heat storage material is lowered by natural heat radiation.
一般の物質では、融点と凝固点とが同じ温度になるが、
主蓄熱材及び温度保障蓄熱材の蓄熱剤は、その温度が融
点より低くなっても、固体化せずに液相を維持し、いわ
ゆる過冷却現象が生じる。主蓄熱材及び温度保障蓄熱材
の温度は、放熱によって最終的に外気温と同じ温度にな
る。しかしながら、この時の放熱は、顕然だけにとどま
り、主蓄熱材及び温度保障蓄熱材には、依然、潜熱の形
で蓄熱されている。For ordinary substances, the melting point and freezing point are the same temperature,
The heat storage agents of the main heat storage material and the temperature-guaranteed heat storage material maintain a liquid phase without solidifying even if their temperature becomes lower than their melting point, resulting in a so-called supercooling phenomenon. The temperature of the main heat storage material and the temperature guaranteed heat storage material eventually becomes the same as the outside temperature due to heat radiation. However, the heat radiation at this time is only obvious, and heat is still stored in the main heat storage material and the temperature guaranteed heat storage material in the form of latent heat.
再度、車を使用するとき、第１の過冷却解除装置を作動
させて主蓄熱材の過冷却を解除すると、主蓄熱材の蓄熱
剤は、液相から固相に変わり、この際、潜熱として蓄え
られていた熱を放出する。When the car is used again, when the first supercooling release device is activated to release the supercooling of the main heat storage material, the heat storage material of the main heat storage material changes from the liquid phase to the solid phase, and at this time, it releases latent heat as latent heat. Releases stored heat.
この結果、蓄熱熱交換装置内で冷却水がいちはやく暖め
られる。この加熱された冷却水は、熱交換器に送込まれ
、車室の暖房の熱源に供される。As a result, the cooling water is quickly warmed up within the heat storage heat exchange device. This heated cooling water is sent to a heat exchanger and is used as a heat source for heating the passenger compartment.
尚、蓄熱材に封入されている蓄熱剤は、余りに過冷却さ
れると、自然に液相から固相に変わり、それまで潜熱と
して蓄えられていた熱を放出してしまう、しかしながら
、本発明によるカーヒーターの場合、主蓄熱材が過冷却
により自然に放熱する前に第２の過冷却解除装置が作動
して温度保障蓄熱材の過冷却を解除し、温度保障蓄熱材
に熱を発生させ、これによって主蓄熱材を加熱し、主蓄
熱材が過冷却により自然に放熱するのを防いでいる。In addition, if the heat storage agent sealed in the heat storage material is supercooled too much, it will naturally change from a liquid phase to a solid phase and release the heat that was previously stored as latent heat.However, according to the present invention, In the case of a car heater, before the main heat storage material naturally radiates heat due to supercooling, a second supercooling release device operates to release the supercooling of the temperature guaranteed heat storage material, and generate heat in the temperature guaranteed heat storage material; This heats the main heat storage material and prevents the main heat storage material from naturally dissipating heat due to overcooling.

くなった場合、温度保障蓄熱材が放熱して主蓄熱材を加
熱するので、過冷却による主蓄熱材の自然放熱を防止す
ることができる。Further, in the car heater according to the present invention, when the outside air becomes extremely low, the temperature-ensuring heat storage material radiates heat and heats the main heat storage material, so that natural heat radiation of the main heat storage material due to overcooling can be prevented.
