用の暖房・給湯システムに関する。[Detailed Description of the Invention] This invention relates to a heating and hot water supply system using solar heat, which uses solar energy collected by a hot-air solar collector to heat a room and supply hot water.

種提案されている。In recent years, in the field of solar houses, the development of hot air type solar collectors with high heat collection efficiency has progressed, and solar thermal energy collected by the collector using air as a medium, that is, heated air, can be directly sent into the room to be heated. Alternatively, various solar systems have been proposed in which heated air is sent to a heat storage tank to temporarily store heat, and when necessary, heated air from the heat storage tank is sent into the room to perform hot air heating.

しかしながら、従来提案のものは暖房専用であって、蓄

用で平時は全く使用されないので設備が無駄になり不経
済である。However, the conventionally proposed systems are only for heating, and by being equipped with a heat storage tank, it is possible to provide uniform heating day and night; however, especially during the cold winter months when heating is required, solar thermal energy cannot be obtained much. Therefore, heating must be done with an auxiliary heat source device such as a heater, and the auxiliary heat source device is only used for heating and is not used at all during normal times, resulting in wasted equipment and uneconomical.

又この補助熱源装置に加えてシステム全体的に見ても暖

あると同時に、その休止時期は太陽熱エネルギーが大で
あってそれを利用しないことは非常に不経済である。In addition to this auxiliary heat source device, when looking at the system as a whole, it is not used and is not used for periods other than when heating is required, that is, at least half a year from spring to autumn, which is a waste of equipment. There is a lot of solar thermal energy during the downtime, and it would be very uneconomical not to use it.

しかも集熱器は屋外に常時装備したままでおかれること

た。Moreover, since the heat collector is always left outdoors, there is a problem that the heat collector becomes overheated when there is a lot of sunlight in the summer, so we have to take the trouble of turning on the fan to cool the room. There was the trouble of having to ventilate commercial air or outside air into the heat collector to suppress abnormal heating.

た実用性大なるシステムを提供することにある。This idea was made in view of the above circumstances, and its purpose is to create a heating system that utilizes solar heat using an air heat collection method using a hot air solar heat collector, and is equipped with a heat storage tank to create a heating system that utilizes solar heat, similar to the conventional one. In addition to being capable of hot air heating, when there is insufficient solar thermal energy such as on cold winter days, the heat from the hot water in the hot water storage tank is used as an auxiliary heat source, eliminating the need for an auxiliary heat source for heating. On the other hand, in times when there is no need for heating due to the large amount of solar thermal energy, instead of just shutting down the system, the hot air energy collected by the heat collector is used to raise the temperature of the hot water in the hot water storage tank and use it to heat the water heater. It has been made possible to effectively utilize solar thermal energy throughout the year, regardless of the four seasons, and to eliminate the waste of various equipment, making it possible to use it for hot air heating and hot water heating very efficiently. Our goal is to provide a system with great practicality.

徴とする太陽熱利用の暖房・給湯システム。A heat collection heating circuit that sends heated air from the hot air solar collector into the room via a blower and returns it to the collector, and a heat collection heating circuit that sends heated air from the heat collector to the heat storage tank via the blower. A heat storage circuit that sends heated air through the heat storage tank and returns it to the heat collector again, and a heat storage heating circuit that sends the heated air from the heat storage tank into the room via the above-mentioned blower and returns it again to the heat storage tank. and a heat exchanger is installed in the common duct of the three circuits, and a hot water storage tank equipped with an auxiliary heat source such as a water heater is separately installed.
By circulating the hot water in the hot water storage tank between the heat exchanger and the heat exchanger, the temperature of the hot water in the tank is raised by hot air from the heat collector or heat storage tank during the summer and other times when solar thermal energy is large, and vice versa during the winter. 1. A heating and hot water supply system using solar heat, characterized in that a hot water circulation circuit with a pump is provided for heating the hot air with hot water in the tank when the solar heat energy is low.
