【０００２】
【従来の技術】
従来、高断熱・高気密住宅における暖房装置や給湯装置又は消雪装置にあっては、省エネで、効率のよいさまざまな装置が提案されているが、いずれも熱源を別とした独立した装置であって、それぞれの熱源は高温であり、直接繋いで使用するために単一用途にしか利用できなかった。
【０００３】
特に温水式暖房装置としては、灯油やガスを熱源として使用したものが一般的で、さらに電気による給湯装置においては貯湯式が主流である。
【０００４】
【発明が解決しようとする課題】
従来技術の問題点としては、従来の暖房装置、給湯装置又は消雪装置はそれぞれ熱源を別にしている為、それぞれの熱源は単一の用途にしか利用されなかった。その為に効率的な熱エネルギーの利用が成されず、省エネを図ることが難しい。また、高断熱住宅においては、暖房において高温をそのまま使用する方法で行われるため、過乾燥による身体への熱負担が大きく、火傷をしたり、室内に気流が生じるなどしてストレスの原因となっている。
【０００５】
また、貯湯式による給湯装置にあっては貯湯槽に錆や湯垢等が発生するため飲用不可であり、数カ所同時給湯の場合は水圧も不足するため２階もしくは数カ所同時に給湯する場合は湯量が不足するなどの問題があった。
【０００６】
本発明は、上記従来技術の有する問題点に鑑みてなされたものであり、その目的とするところは、安価の深夜電力を利用した蓄熱式電気ボイラーにより蓄熱された熱エネルギーを高断熱高気密住宅の暖房と給湯の熱源として複数の用途に使用することで熱エネルギーの効率的な運用を可能とし、また、三方弁を介した配管接続されたシステムとすることで低温で安定的な温水を供給することにより低温輻射熱方式の暖房を行い、省エネで経済的、かつ過乾燥を防止して、快適で健康的な空間を創る高断熱・高気密住宅用蓄熱式低温省エネ熱エネルギーシステムを提供することである。
【０００７】
【課題を解決するための手段】
上記目的を達成する為、本発明に係る給湯システムは、本出願人が平成１３年５月２１日出願した特願２００１−１９１９９８号記載の蓄熱式電気温水パネル暖房システムにおいて、該システムの所定位置に熱交換器を付設して、水道水を該熱交換器を経由させることで暖房用熱エネルギーにより水道水を瞬時に暖めて温水として台所や浴室等に給湯するシステムとした。

図５は請求項１１に記載のシステムの一実施例を示したシステム図であり、蓄熱式電気ボイラー１を冷水槽を有する冷却装置２０とすることで、冷却され貯水槽に蓄えられた冷水が配管接続されたシステム内を循環して冷房を行うようにしたものである。
【００２１】
【発明の効果】
以上説明したように本発明のシステムは高断熱・高気密住宅の暖房と給湯を一つの熱源で行う為、しかもその熱源も割安な深夜電力等を利用した蓄熱式である為、また三方弁を設けたシステム回路としている為、低温で安定的な温水の供給により低温輻射熱方式の暖房を行うことができるので、省エネで経済的であり、かつ室内の過乾燥を防止して気流がない快適で健康的な空間とすることでストレスをなくすことができる。
本発明の給湯は熱交換器による水道直結瞬間湯沸し方式である為、高圧給湯で２階ヘの供給も可能であるとともに衛生的な温水の供給ができる。また、本発明の燃料電池からなる自家発電装置を深夜電力利用の蓄熱式ボイラーに接続した場合、本来自家発電装置で賄っている給湯・暖房の必要エネルギーを深夜電力で補えるから、該自家発電装置自体の発電能力を低く押えることができる。さらに、太陽光発電の際の余剰余熱やヒートポンプによって蓄熱された温水を利用すれば、より省エネで経済的である。
また、電気ボイラー内の蓄熱槽に貯水された冷却水を使用すれば、冷房も省エネで行うことが可能である。

FIG. 1 is a system diagram showing one embodiment of the present invention, in which a regenerative electric boiler 1, an air separator 6, a circulation pump 3B, a water supply control header 5A, a return water control header 5B, a temperature control three-way valve 7, A heating system is constituted by the actuator 8, the hot water temperature controller 9, the closed expansion tank 10, the heating panel heater 2, and the heating hot water pipe 12. In a hot water pipe path including the electric boiler 1, the temperature control three-way valve 7, and the closed expansion tank 10, a heat exchanger 4, a circulation pump 3A, a relay switch 11 for turning on / off the circulation pump 3A, and a water pipe 13 are provided. A hot water supply system is configured.
[0010]
The electric boiler 1 is of a heat storage type in which water stored in a heat storage tank is heated and stored by a heater using electric power at midnight, and the capacity of the heat storage tank is 300 to 3000 liters.
[0011]
The hot water warmed by the regenerative electric boiler 1 circulates through a circulation path 2 as shown below, is supplied to heating panel heaters 2 installed in each room, and is radiated at a low temperature by the heating panel heaters 2. As a result, the heating in the house is performed at low temperature and energy saving. When the temperature of the hot water circulating in the circulation path 2 decreases, the temperature control three-way valve 7 is automatically or manually switched so that the hot water circulates in the circulation path 1, and the temperature of the hot water is again reduced to a predetermined temperature by the electric boiler 1. To raise. The present invention is an energy-saving system for the purpose of low-temperature and stable supply in which the circulation paths 1 and 2 are automatically switched according to the set temperature of hot water by the hot water temperature controller 9 and the temperature control three-way valve 7. In the case of a self-propelled system in which the circulation path is automatically switched in the three-way valve 7, the actuator 8 and the temperature controller 9 are unnecessary.
Figure 2004108759
[0012]
In the hot water supply system of the present invention, a heat exchanger 4 is attached to a predetermined position of the circulation path 1 of the heating system, and tap water passes through the water pipe 13 and passes through the heat exchanger 4 to a kitchen or a bathroom. Supplied configuration. At the same time that the faucet of the kitchen or bathroom is opened, the relay switch 11 attached to a predetermined position of the water pipe 13 detects this and activates the circulation pump 3A to supply the heat exchanger 4 with hot water in the heat storage tank. The heat energy of the hot water in the heat storage tank is converted in the heat exchanger 4 so that the tap water is instantaneously warmed and supplied to the kitchen or bathroom as hot water for hot water supply. The heat exchanger 4 used here has a heat exchange capacity of 34,400 kcal / hr, and can raise the temperature to a maximum temperature of 90 ° C.
[0013]
Table 1 below shows a comparison between heating and hot water supply by hot water using an electric boiler using midnight power and heating and hot water supply by a kerosene boiler according to the present invention. The capacity of the heat storage tank in the electric boiler is estimated at 2,000, 2500, and 2700 liters, respectively. The annual consumption of the kerosene boiler is the consumption corresponding to the heater of the electric boiler, and the annual consumption rate of kerosene Is calculated at 44.2 yen per liter. The discounted annual amount is calculated on a trial basis with Tohoku Electric Power Co., Inc. as a time-specific lighting contract for equipment that can be energized for 5 hours at midnight. As shown in the table below, the use of the energy saving system of the present invention makes it possible to heat and supply hot water to a house at a low running cost.
[Table 1]
Figure 2004108759
[0014]
Claim 3 is a system in which a snow melting system is added to the heating / hot water supply system, and a hot water pipe for snow removal connected via a temperature control three-way valve 7 from a water supply amount control header or a predetermined position of the circulation path 1 is provided around the entrance. It melts snow by burying it in a parking lot or circulating hot water through a hot water pipe for snow removal. Since the heat source uses the heat source for heating and hot water supply or uses the three-way valve 7 for temperature control, the heat energy is efficiently used.
[0015]
The hot water pipe for snow melting used in the present invention has a double structure, and by providing an air layer between the hot water circulating in the center of the hot water pipe and the outside, the temperature of the hot water is prevented from remarkably lowering due to external cooling. This allows for uniform snow melting at the beginning and end of the pipe.
[0016]
FIG. 2 is a system diagram showing an embodiment of the system according to claim 4 and claim 7, wherein a private power generator 14 for residential use comprising a fuel cell and a regenerative electric boiler 1 are connected to a heat exchanger 14 and a circulation pump. In this system, heat is stored in the electric boiler 1 by the residual heat generated by the private power generator, and heating, hot water supply, and snow melting are performed using the stored heat energy. When the amount of heat from the private power generator is insufficient, heat can be stored by heating with midnight power.
[0017]
FIG. 3 is a system diagram showing an embodiment of the system according to claim 5, wherein the solar heat collector 18 and the regenerative electric boiler 1 are connected to each other via a heat exchanger 15 and a circulation pump 16. This system stores heat using solar thermal energy, and uses this stored energy for heating, hot water supply, and snow melting.
[0018]
FIG. 4 is a system diagram showing an embodiment of the system according to claim 6 and claim 9, wherein the regenerative electric boiler 1 and the heat pump 19 are connected by piping via a heat exchanger and a circulation pump. This is a system in which heat from the heat pump 19 is stored, and heating, hot water supply, and snow melting are performed using the stored heat energy. When the amount of heat by the heat pump is small, the amount of heat storage can be supplemented by heating with midnight power or daytime power.
[0019]
In this embodiment, the system is configured by using a heat exchanger and two circulation pumps. However, between the private power generator 14 composed of a fuel cell, the solar heat collector 18, or the heat pump 19 and the regenerative electric boiler 1 is used. In the case of complete sealing, it is also possible to connect the electric boiler directly to a private power generator or a solar heat collector without using a heat exchanger, and in this case, one circulation pump is sufficient. If the heat is stored by utilizing the surplus heat of the private power generation or the solar heat in addition to the late-night power, it is even more energy-saving and economical.
[0020]
FIG. 5 is a system diagram showing one embodiment of the system according to claim 11, wherein the regenerative electric boiler 1 is a cooling device 20 having a chilled water tank, whereby the chilled water cooled and stored in the water storage tank is reduced. In this system, cooling is performed by circulating in a system connected by piping.
[0021]
【The invention's effect】
As described above, since the system of the present invention performs heating and hot water supply of a highly insulated and airtight house with one heat source, and since the heat source is also a heat storage type using inexpensive midnight power, a three-way valve is used. Since the system circuit is provided, low-temperature radiant heating can be performed by supplying stable hot water at low temperature, so it is energy-saving and economical, and it is comfortable without airflow by preventing over-drying in the room. A healthy space can eliminate stress.
Since the hot water supply of the present invention is an instantaneous water heating system directly connected to a water supply by a heat exchanger, high-pressure hot water can be supplied to the second floor and sanitary hot water can be supplied. In addition, when the private power generator including the fuel cell of the present invention is connected to a regenerative boiler using late-night power, the required energy for hot water supply and heating originally provided by the private power generator can be supplemented by the late-night power, so that the private power generator can be used. Its own power generation capacity can be kept low. Further, if surplus heat at the time of photovoltaic power generation or hot water stored by a heat pump is used, it is more energy saving and economical.
Moreover, if the cooling water stored in the heat storage tank in the electric boiler is used, the cooling can be performed with energy saving.
