本発明は、ソーラー暖房システムに関する。   The present invention relates to a solar heating system.

太陽熱集熱器で集熱した熱を屋内の暖房に用いるソーラー暖房システムは、従来より提供されているが、晴れる日もあれば、曇りや雪、雨の日もあり、また、天候にかかわらず夜間は太陽熱を集熱することができず、そのため、暖房が安定良く行われないという問題がある。   Solar heating systems that use the heat collected by solar collectors for indoor heating have been provided, but there are sunny days, cloudy, snowy, and rainy days. There is a problem that solar heat cannot be collected at night, and heating is not performed stably.

そこで、太陽熱集熱器で集熱した熱を蓄熱装置に蓄熱し、夜間や曇り、雪、雨の日には、蓄熱装置に蓄熱された太陽熱で暖房を行うようにすることが考えられる。   Therefore, it is conceivable that the heat collected by the solar heat collector is stored in the heat storage device, and heating is performed with solar heat stored in the heat storage device at night, on a cloudy day, on a snowy or rainy day.

しかしながら、曇りや雪、雨の日が続く場合には、蓄熱装置に蓄熱された太陽熱だけでは暖房を継続することができず、それを実現するには蓄熱容量の大きい大型の蓄熱装置が必要になり、蓄熱装置を設置するスペースの確保が難しくなるという問題がある。   However, if it continues to be cloudy, snowy, or rainy, heating cannot be continued with only the solar heat stored in the heat storage device, and a large heat storage device with a large heat storage capacity is required to achieve this. Therefore, there is a problem that it is difficult to secure a space for installing the heat storage device.
