Description
本発明は、太陽熱収集パネルを用いた蓄熱式暖房システム、及びこの暖房システムを備えた建物に関するものである。 The present invention relates to a regenerative heating system using a solar heat collecting panel and a building equipped with the heating system.
従来から、太陽熱収集パネルを用いた蓄熱式暖房システムが知られている。 Conventionally, a regenerative heating system using a solar heat collecting panel is known.
例えば、特許文献１には、建物の床下空間に設けられた熱交換器に太陽熱収集パネルから熱媒体を供給し、床下空間を暖め、同じく床下空間に設けられた蓄熱体に蓄熱して直上の床上空間を暖めることが可能な蓄熱式暖房システムが開示されている。 For example, in Patent Document 1, a heat medium is supplied from a solar heat collection panel to a heat exchanger provided in the underfloor space of a building, the underfloor space is warmed, and heat is stored in a heat storage body that is also provided in the underfloor space. A regenerative heating system capable of warming the space above the floor is disclosed.
しかしながら、特許文献１に開示された従来の蓄熱式暖房システムでは、蓄熱体を床下空間への放熱手段としてしか用いていなかった。 However, in the conventional heat storage type heating system disclosed in Patent Document 1, the heat storage body is used only as a heat radiating means to the underfloor space.
また、特許文献１に開示された従来の蓄熱式暖房システムでは、長時間にわたって床下空間側からその直上の床上空間を暖めることが可能なものの、蓄熱体が所定の温度以下に低下してしまうと、蓄熱体は、床上空間を暖めるほどの床下空間への放熱手段としては用をなさなくなり、それなりの熱エネルギーを有していながらも、用いられることがなかった。 Moreover, in the conventional regenerative heating system disclosed in Patent Document 1, although it is possible to warm the above-floor space immediately above the underfloor space for a long time, the regenerator decreases to a predetermined temperature or lower. The heat accumulator is no longer used as a means for radiating heat to the under-floor space that warms the above-floor space, and has a certain amount of heat energy, but has not been used.
そこで、本発明は、蓄熱体を床下空間への放熱手段以外にも用いることができるうえに、より効率的に蓄熱体に蓄熱した熱エネルギーを利用することができる蓄熱式暖房システム、及びこの暖房システムを備えた建物を提供することを目的としている。 Therefore, the present invention can use the heat storage body other than the heat radiating means to the underfloor space, and more efficiently use the heat energy stored in the heat storage body, and this heating system. It aims to provide buildings with systems.
前記目的を達成するために、本発明の蓄熱式暖房システムは、太陽熱収集パネルと、建物の床下空間に設けられた蓄熱体と、ヒートポンプ室内機に接続されたヒートポンプ室外機とを備え、前記蓄熱体は、前記太陽熱収集パネルと内部を熱媒が循環する配管で接続されているとともに、前記ヒートポンプ室外機とも内部を熱媒が循環する配管で接続されており、前記床下空間への放熱手段と前記ヒートポンプ室外機の熱源とに利用可能とされていることを特徴とする。 In order to achieve the above object, a regenerative heating system of the present invention comprises a solar heat collection panel, a heat storage body provided in a space under a building, and a heat pump outdoor unit connected to a heat pump indoor unit, and the heat storage The body is connected to the solar heat collection panel by a pipe through which a heat medium circulates, and is connected to the heat pump outdoor unit by a pipe through which a heat medium circulates. The heat pump outdoor unit can be used as a heat source.
ここで、前記床下空間は、側壁は断熱材が取り付けられた断熱構造とされ、直上の床上空間との間を仕切る床部は熱が伝導しやすい熱伝導構造とされているとよい。 Here, the underfloor space may have a heat insulating structure in which a side wall is provided with a heat insulating material, and a floor portion that partitions the space directly above the floor space may have a heat conducting structure that easily conducts heat.
また、前記ヒートポンプ室内機は、前記建物の屋内に設けられたヒートポンプ式のエアコンディショナーであるとよい。 The heat pump indoor unit may be a heat pump type air conditioner provided indoors in the building.
さらに、前記ヒートポンプ室外機は、前記建物の屋外に設けられており、前記蓄熱体と大気を熱源に利用可能であるとよい。 Furthermore, the heat pump outdoor unit may be provided outside the building, and the heat storage body and the atmosphere may be used as a heat source.
また、前記蓄熱体を前記床下空間への放熱手段に利用した後、所定の温度以下に低下すると、前記ヒートポンプの熱源に利用するとよい。 Moreover, after using the said thermal storage body for the thermal radiation means to the said underfloor space, when it falls below below predetermined temperature, it is good to utilize for the heat source of the said heat pump.
本発明の建物は、上記した本発明の蓄熱式暖房システムを備えていることを特徴とする。 The building of the present invention includes the above-described heat storage heating system of the present invention.
このような本発明の蓄熱式暖房システムは、太陽熱収集パネルと、建物の床下空間に設けられた蓄熱体と、ヒートポンプ室内機に接続されたヒートポンプ室外機とを備え、蓄熱体は、太陽熱収集パネルと内部を熱媒が循環する配管で接続されているとともに、ヒートポンプ室外機とも内部を熱媒が循環する配管で接続されており、床下空間への放熱手段とヒートポンプ室外機の熱源とに利用可能とされた構成とされている。 Such a heat storage type heating system of the present invention includes a solar heat collection panel, a heat storage body provided in a space under the building, and a heat pump outdoor unit connected to the heat pump indoor unit, and the heat storage body is a solar heat collection panel. Is connected to the heat pump outdoor unit by a pipe circulating the heat medium inside, and can be used as a heat radiation means to the underfloor space and the heat source of the heat pump outdoor unit. It is set as the structure.
上記した構成なので、蓄熱体を、床下空間への放熱手段としてだけでなく、ヒートポンプ室外機の熱源にも利用することができる。 Since it is the above-described configuration, the heat storage body can be used not only as a heat radiating means to the underfloor space but also as a heat source of the heat pump outdoor unit.
ここで、床下空間は、側壁は断熱材が取り付けられた断熱構造とされ、直上の床上空間との間を仕切る床部は熱が伝導しやすい熱伝導構造とされている場合は、側壁から熱が屋外へ逃げるのを極力防止できるとともに、床部の下面から上面へ熱が伝わりやすいので、効率のよい床下暖房を行うことができる。 Here, when the underfloor space has a heat insulating structure with a heat insulating material attached to the side wall, and the floor portion separating the space above the floor above has a heat conducting structure that easily conducts heat, heat is generated from the side wall. Can be prevented from escaping to the outside as much as possible, and heat is easily transferred from the lower surface of the floor portion to the upper surface, so that efficient underfloor heating can be performed.
また、ヒートポンプ室内機は、建物の屋内に設けられたヒートポンプ式のエアコンディショナーである場合は、蓄熱体を、床下暖房だけでなく、吹出型の暖房にも利用することができる。 In addition, when the heat pump indoor unit is a heat pump type air conditioner provided in a building, the heat storage body can be used not only for underfloor heating but also for blowout type heating.
さらに、ヒートポンプ室外機は、建物の屋外に設けられており、蓄熱体と大気を熱源に利用可能である場合は、大気の温度より高い温度の蓄熱体が熱源として補うので、成績係数（ＣＯＰ）を高めることができる。 Furthermore, the heat pump outdoor unit is provided outside the building, and when the heat storage body and the atmosphere can be used as a heat source, the heat storage body having a temperature higher than the temperature of the atmosphere supplements the heat source, so the coefficient of performance (COP) Can be increased.
また、蓄熱体を床下空間への放熱手段に利用した後、所定の温度以下に低下すると、ヒートポンプ室外機の熱源に利用する場合は、床上空間を暖めるほどの床下空間への放熱手段としては不充分な所定の温度以下に低下した蓄熱体の熱エネルギーを有効利用することができ、より効率的である。更に、ヒートポンプ室外機によって熱を奪われて蓄熱体の温度が低下するので、翌日の太陽熱の吸収効率が向上する。 In addition, if the heat storage body is used as a heat source for the underfloor space and then falls below a predetermined temperature, when used as a heat source for the heat pump outdoor unit, it is not suitable as a heat dissipating means for the underfloor space to warm the floor space. It is possible to effectively use the heat energy of the heat storage body that has been lowered to a predetermined temperature or lower, which is more efficient. Furthermore, since heat is taken away by the heat pump outdoor unit and the temperature of the heat storage body is lowered, the solar heat absorption efficiency of the next day is improved.
このような本発明の建物は、上記した本発明の蓄熱式暖房システムを備えた構成とされている。 Such a building of the present invention is configured to include the above-described heat storage heating system of the present invention.
上記した構成なので、上記した本発明の蓄熱式暖房システムの効果を奏する建物とすることができる。 Since it is an above-mentioned composition, it can be set as a building which has an effect of an above-mentioned regenerative heating system of the present invention.

そして、この天井部１ｅと外壁部１ｄとに囲まれる空間は、床部１ａによって床下空間４と居室などに用いられる床上空間５とが区切られた構成となっている。 The space surrounded by the ceiling portion 1e and the outer wall portion 1d has a configuration in which a floor space 1 and a floor space 5 used for a living room or the like are separated by a floor portion 1a.
ここで、床部１ａは、下面から上面へ熱が伝わりやすい熱伝導構造とされている。 Here, the floor portion 1a has a heat conduction structure in which heat is easily transmitted from the lower surface to the upper surface.
また、基礎側壁コンクリート１ｃの床下空間４側には、グラスウールなどの断熱材１０が取り付けられており、床下空間４内の熱が屋外に極力漏れない断熱構造となっている。 Further, a heat insulating material 10 such as glass wool is attached to the underfloor space 4 side of the foundation side wall concrete 1c, so that heat in the underfloor space 4 is prevented from leaking to the outside as much as possible.
そして、床下空間４内には、蓄熱体３が設けられている。 And in the underfloor space 4, the heat storage body 3 is provided.
また、建物１の太陽熱収集可能位置である屋上には、太陽熱収集パネル６が設けられており、内部を熱媒としての水が循環する配管８で蓄熱体３と接続されている。 A solar heat collecting panel 6 is provided on the rooftop of the building 1 where solar heat can be collected. The solar heat collecting panel 6 is connected to the heat storage body 3 through a pipe 8 through which water as a heat medium circulates.
さらに、建物１の屋外には、大気及び蓄熱体３を熱源とすることが可能なヒートポンプ室外機２が設けられており、内部を熱媒としての水が循環する配管９で蓄熱体３と接続されている。 Further, a heat pump outdoor unit 2 capable of using the atmosphere and the heat storage body 3 as a heat source is provided outside the building 1 and is connected to the heat storage body 3 through a pipe 9 through which water as a heat medium circulates.

次に、実施例の蓄熱式暖房システムの運転パターンの一例を示す。 Next, an example of the operation pattern of the regenerative heating system of the embodiment is shown.
朝から日中の前半にかけて、太陽熱収集パネル６から収集された熱が、熱媒としての水を介して蓄熱体３に蓄熱される。 From the morning to the first half of the day, the heat collected from the solar heat collecting panel 6 is stored in the heat storage body 3 through water as a heat medium.
このとき、蓄熱体３は約４０℃レベルまで達する。 At this time, the heat storage body 3 reaches a level of about 40 ° C.
日中の後半から夜にかけて、この蓄熱体３に蓄熱した熱を床下空間４へ放熱し、床上空間５が床部１ａを介して、ムラなく暖まるように床下暖房を行う（図１の状態）。 From the latter half of the day to the night, the heat stored in the heat storage body 3 is radiated to the underfloor space 4, and underfloor heating is performed so that the overfloor space 5 is warmed uniformly through the floor 1a (state of FIG. 1). .
このとき、蓄熱体３は約４０℃〜３０℃の間のレベルである。 At this time, the heat storage body 3 is a level between about 40 degreeC-30 degreeC.
深夜から翌日の明け方にかけて、この蓄熱体３に残った熱と大気を熱源としてヒートポンプ室外機２を稼働し、床上空間５が温風で暖まるエアコンディショナー７による吹出型の暖房を行う（図２の状態）。 From midnight to dawn the next day, the heat pump outdoor unit 2 is operated using the heat and air remaining in the heat storage body 3 as heat sources, and the air-conditioner 7 that warms the floor space 5 with warm air performs blow-out type heating (see FIG. 2). State).
このとき、蓄熱体３は３０℃以下のレベルまで低下しており、床上空間５を床下暖房で暖めるほどの床下空間４への放熱手段としては不充分なものとなっている。 At this time, the heat storage body 3 is lowered to a level of 30 ° C. or lower, and is insufficient as a heat radiation means to the underfloor space 4 to warm the underfloor space 5 by underfloor heating.
更に、ヒートポンプ室外機２によって熱を奪われて蓄熱体３の温度は翌日の朝には１０℃程度まで低下する。 Furthermore, heat is taken away by the heat pump outdoor unit 2, and the temperature of the heat storage body 3 decreases to about 10 ° C. in the morning of the next day.
次に、実施例の作用効果について説明する。 Next, functions and effects of the embodiment will be described.
このような実施例の蓄熱式暖房システムは、建物１の太陽熱収集可能位置である屋上に設けられた太陽熱収集パネル６と、建物１の床下空間４に設けられた蓄熱体３と、建物１の屋内に設けられたヒートポンプ室内機であるエアコンディショナー７に接続されたヒートポンプ室外機２とを備え、蓄熱体３は、太陽熱収集パネル６と内部を熱媒が循環する配管８で接続されているとともに、ヒートポンプ室外機２とも内部を熱媒が循環する配管９で接続されており、床下空間４への放熱手段とヒートポンプ室外機２の熱源とに利用可能とされた構成とされている。 The heat storage type heating system of such an embodiment includes a solar heat collection panel 6 provided on the roof that is a solar heat collecting position of the building 1, a heat storage body 3 provided in the underfloor space 4 of the building 1, and the building 1 A heat pump outdoor unit 2 connected to an air conditioner 7 which is a heat pump indoor unit provided indoors, and the heat storage body 3 is connected to the solar heat collecting panel 6 and a pipe 8 through which a heat medium circulates. The heat pump outdoor unit 2 is also connected by a pipe 9 through which a heat medium circulates, and is configured to be usable as a heat radiating means to the underfloor space 4 and a heat source of the heat pump outdoor unit 2.
上記した構成なので、蓄熱体３を、床下空間４への放熱手段としてだけでなく、ヒートポンプ室外機２の熱源にも利用することができる。 Due to the above configuration, the heat storage body 3 can be used not only as a heat radiating means to the underfloor space 4 but also as a heat source of the heat pump outdoor unit 2.
ここで、床下空間４は、側壁としての基礎側壁コンクリート１ｃは断熱材１０が取り付けられた断熱構造とされ、直上の床上空間５との間を仕切る床部１ａは熱が伝導しやすい熱伝導構造とされている。 Here, the underfloor space 4 has a heat insulating structure in which the heat insulating material 10 is attached to the foundation side wall concrete 1c as a side wall, and the floor portion 1a that partitions the space 5 directly above the floor space 5 is a heat conductive structure that easily conducts heat. It is said that.
このため、側壁としての基礎側壁コンクリート１ｃから熱が屋外へ逃げるのを極力防止できるとともに、床部１ａの下面から上面へ熱が伝わりやすいので、効率のよい床下暖房を行うことができる。 For this reason, it is possible to prevent heat from escaping from the basic side wall concrete 1c as a side wall as much as possible, and heat is easily transmitted from the lower surface to the upper surface of the floor portion 1a, so that efficient underfloor heating can be performed.
また、ヒートポンプ室内機は、建物１の屋内である床上空間５に設けられたヒートポンプ式のエアコンディショナー７である。 The heat pump indoor unit is a heat pump type air conditioner 7 provided in a floor space 5 inside the building 1.
このため、蓄熱体３を、床下暖房だけでなく、吹出型の暖房にも利用することができる。 For this reason, the heat storage body 3 can be utilized not only for underfloor heating but also for blowout type heating.
さらに、ヒートポンプ室外機２は、建物１の屋外に設けられており、蓄熱体３と大気を熱源に利用可能である。 Furthermore, the heat pump outdoor unit 2 is provided outside the building 1 and can use the heat storage body 3 and the atmosphere as a heat source.
このため、大気の温度より高い温度の蓄熱体３が熱源として補うので、成績係数（ＣＯＰ）を高めることができる。 For this reason, since the heat storage body 3 having a temperature higher than the atmospheric temperature compensates as a heat source, the coefficient of performance (COP) can be increased.
また、蓄熱体３を床下空間４への放熱手段に利用した後、所定の温度（ここでは３０℃）以下に低下すると、ヒートポンプ室外機２の熱源に利用する。 In addition, after the heat storage body 3 is used as a heat radiating means to the underfloor space 4, the heat storage body 3 is used as a heat source for the heat pump outdoor unit 2 when it falls below a predetermined temperature (30 ° C. in this case).
このため、床上空間５を暖めるほどの床下空間４への放熱手段としては不充分な所定の温度（ここでは３０℃）以下に低下した蓄熱体３の熱エネルギーを有効利用することができ、より効率的である。更に、ヒートポンプ室外機２によって熱を奪われて蓄熱体３の温度が低下するので、翌日の太陽熱の吸収効率が向上する。 For this reason, it is possible to effectively use the heat energy of the heat storage body 3 that has decreased below a predetermined temperature (30 ° C. in this case) that is insufficient as a heat radiation means to the underfloor space 4 that warms the underfloor space 5. Efficient. Furthermore, since heat is taken away by the heat pump outdoor unit 2 and the temperature of the heat storage body 3 decreases, the solar heat absorption efficiency of the next day is improved.
