Description
本考案は、ＣＯ2 冷媒ヒートポンプ式給湯機の排冷気利用冷房システムに関し、特にＣＯ2 冷媒ヒートポンプ式給湯機から排出される排冷気を利用して建物の内部を冷房する冷房システムに関する。 This invention relates to exhaust cold air used air-cooling system of CO 2 refrigerant heat pump water heater, to a cooling system for cooling the interior of the building by utilizing the discharge cold air is discharged from the particular CO 2 refrigerant heat pump water heater.
ＣＯ2 冷媒を採用したヒートポンプ式給湯機が複数機種開発され、実用に供されている。例えば、この種の電気式給湯機の場合、消費する電気エネルギの約２倍のエネルギを外気から取り込んで給湯する。このとき、外気からヒートポンプにより熱エネルギを回収するため、給湯機に取り込まれた外気は約１０℃程温度低下し、この低温の冷気が給湯機から大気中へ排出されている。 Several types of heat pump water heaters using CO 2 refrigerant have been developed and put into practical use. For example, in the case of this type of electric water heater, hot water is supplied by taking in energy about twice as much as the consumed electric energy from the outside air. At this time, since heat energy is recovered from the outside air by a heat pump, the temperature of the outside air taken into the water heater decreases by about 10 ° C., and this low-temperature cold air is discharged from the water heater into the atmosphere.
ここで、木造の住宅用建物のうちツーバイフォー構造の建物においては、通常、その側壁構造が、内壁及び外壁と、これら内外壁に適当間隔おきに固着された多数の縦向きの骨部材とで構成され、内壁と外壁の間に、厚さ約１００ｍｍの断熱空間が形成され、その断熱空間に断熱材が設けられている。１階の側壁構造の内部の断熱空間は１階と２階の間の天井裏空間に連なっている。そして、２階の側壁構造の内部の断熱空間は、前記の天井裏空間と屋根裏空間に連通され、屋根裏空間の頂部には空気抜き孔が形成されている。 Here, in a two-by-four structure of a wooden residential building, the side wall structure is usually composed of an inner wall and an outer wall, and a number of longitudinal bone members fixed to the inner and outer walls at appropriate intervals. A heat insulating space having a thickness of about 100 mm is formed between the inner wall and the outer wall, and a heat insulating material is provided in the heat insulating space. The heat insulating space inside the side wall structure on the first floor is connected to the ceiling space between the first floor and the second floor. The heat insulation space inside the side wall structure on the second floor communicates with the ceiling space and the attic space, and an air vent hole is formed at the top of the attic space.
本考案と密接に関連する技術ではないが、特許文献１には、外気を利用して室内の暖房や冷房効果を得る為の空気循環システムが提案されている。この空気循環システムでは、側壁内空気通路から屋根裏空間に外気を導入したり、給気管を介して貯水槽等で冷却された外気を床下空間に導入してその外気を給気管を介して屋根裏空間に導入し、その屋根裏空間に導入した外気を建物の内部の各部屋に分配することで暖房効果や冷房効果を得るようになっている。
従来、前記ヒートポンプ式給湯機から発生する冷気を建物の内部の冷房に活用することは可能である。この場合、給湯機から発生する冷気をダクトを介して各部屋に導入することになる。給湯機から発生する冷気は、外気よりも約１０℃も低温であるため、冷気をダクトを介して各室へ導入し、室内への吹き出し口に温度調節機能と吹出し機能のあるファンユニットを設けることになる。 Conventionally, it is possible to utilize the cold air generated from the heat pump type water heater for cooling the inside of a building. In this case, cold air generated from the water heater is introduced into each room through the duct. Since the cold air generated from the water heater is about 10 ° C. lower than the outside air, the cold air is introduced into each room through a duct, and a fan unit having a temperature adjustment function and a blow-out function is provided at the indoor outlet. It will be.
そのため、前記のような各室へ冷気を導入する長いダクト類と、温度調節機能と吹き出し機能のあるファンユニットを設けなければならないので、設備費もかなり高価になる等の問題があるため、未だ実用化されていない。
本考案の目的は、ＣＯ2 冷媒ヒートポンプ式給湯機から発生する冷気と、建物の側壁内空気通路、屋根裏空間等を有効活用して建物の内部空間を冷房する冷房システムを提供することである。
Therefore, it is necessary to provide long ducts for introducing cold air into each room as described above, and a fan unit having a temperature control function and a blowing function. Not put into practical use.

It flows downward from 29 and is introduced into the ceiling space 25, and most of the cold air flows upward through the air passage 29 in the side wall and is introduced into the attic space 31.
屋根裏空間３１に導入された冷気の一部は、２階の天井構造１０の天井壁の上面側の天井上面空気通路に沿って流動して、２階部分３の内部空間３ａを冷房する。屋根裏空間３１内の冷気の一部は、屋根構造１１の頂部の空気抜き孔より外部へ放出され、冷気の大部分は、２階側壁構造９の複数の側壁内空気通路２９内を下方へ流れて１階と２階の間の天井裏空間２５に流入する。天井裏空間２５に流入した冷気は、１階の天井壁を隔てて１階の内部空間２ａを冷房し、天井裏空間２５の冷気の一部は１階の庇部７ａから外部へ放出されると共に、１階側壁構造６の複数の側壁内空気通路２３内を下方へ流れ、それら側壁内空気通路２３の下端から床下空間２ｂに供給され、この床下空間２ｂから外部へ放出される。 A part of the cool air introduced into the attic space 31 flows along the ceiling upper surface air passage on the upper surface side of the ceiling wall of the second floor ceiling structure 10 to cool the internal space 3a of the second floor portion 3. A part of the cool air in the attic space 31 is discharged to the outside through the air vent hole at the top of the roof structure 11, and most of the cool air flows downward in the plurality of air passages 29 in the side walls of the second-floor side wall structure 9. It flows into the ceiling space 25 between the first floor and the second floor. The cold air that has flowed into the ceiling space 25 cools the internal space 2a on the first floor across the ceiling wall on the first floor, and a part of the cold air in the ceiling space 25 is discharged to the outside from the flange 7a on the first floor. At the same time, it flows downward through the plurality of in-side wall air passages 23 of the first-floor side wall structure 6, is supplied to the under-floor space 2b from the lower ends of the in-side-wall air passages 23, and is discharged from the under-floor space 2b to the outside.
このように、１階側壁構造６内の複数の側壁内空気通路２３と、天井裏空間２５と、 ２階側壁構造９内の複数の側壁内空気通路２９と、屋根裏空間３１に、冷気が供給されるため、建物Ｈ内の内部空間２ａ，３ａが全体的に冷却され、十分な冷房効果が得られる。 In this way, the cold air is supplied to the plurality of air passages 23 in the first side wall structure 6, the ceiling space 25, the plurality of air passages 29 in the second floor side wall structure 9, and the attic space 31. Therefore, the internal spaces 2a and 3a in the building H are cooled as a whole, and a sufficient cooling effect is obtained.
特に、夏期、２階部分３は１階部分２に比較して５〜１９℃温度が高くなるが、２階部分３については、屋根裏空間３１と側壁構造９の内部の多数の側壁内空気通路２９に外気よりも約１０℃低温の冷気が絶えず流入するため、２階部分３の内部空間３ａを効果的に冷房することができる。１階部分２については、その天井裏空間２５に前記のような冷気が絶えず流入するため、天井サイドから内部空間２ａを効果的に冷房することができる。 In particular, in summer, the second-floor portion 3 has a temperature of 5 to 19 ° C. higher than that of the first-floor portion 2, but for the second-floor portion 3, a large number of air passages in the side walls inside the attic space 31 and the side wall structure 9. Since cold air having a temperature of about 10 ° C. lower than the outside air constantly flows into the air 29, the internal space 3a of the second floor portion 3 can be effectively cooled. As for the first floor portion 2, since the cold air as described above constantly flows into the ceiling space 25, the internal space 2 a can be effectively cooled from the ceiling side.
前記ヒートポンプ式給湯機３２は、通常夜間電力により稼働させる場合が多い関係上、この冷房システムも夜間に稼働させる場合が多い。図５には、外気温度と、ヒートポンプ式給湯機３２から排出される冷気の温度などの関係が示されており、夏期深夜の外気温度が２０〜２７℃のとき、給湯機３２から排出される冷気の温度が約１０〜１７℃となり、本願の冷房システムが稼働可能である。 Since the heat pump type hot water heater 32 is usually operated by electric power at night, this cooling system is often operated at night. FIG. 5 shows the relationship between the outside air temperature and the temperature of the cold air discharged from the heat pump hot water heater 32. When the outdoor air temperature in the summer midnight is 20 to 27 ° C., the air is discharged from the water heater 32. The temperature of the cold air is about 10 to 17 ° C., and the cooling system of the present application can be operated.
特に、この冷房システムにおいては、給湯機３２からの冷気を各室に導入する為のダクト部材を設けることなく、１階や２階の側壁内空気通路２３，２９、天井裏空間２５、屋根裏空間３１などの空気通路を有効活用して、冷房用の冷気を流すので、設備費を節減でき、各室に温度調節機能や吹出し機能のあるファンユニット等を設ける必要もないし、冷房能力の調整は、ダクト部材３４の近くにおいて冷気の風量を絞る等により行うことができるから有利である。 In particular, in this cooling system, the air passages 23 and 29 in the side walls on the first and second floors, the ceiling space 25, the attic space are provided without providing duct members for introducing the cold air from the water heater 32 into each room. The air passages such as 31 can be effectively used to flow cooling air, so that the equipment costs can be reduced, and it is not necessary to provide a fan unit or the like having a temperature adjusting function or a blowing function in each room. This is advantageous because it can be performed by reducing the amount of cool air near the duct member 34.
この実施例２は、実施例１のＣＯ2 冷媒ヒートポンプ式給湯機の排冷気利用冷房システムを部分的に変更した例であるので、変更した部分についてのみ説明する。
図６に示すように、２階側壁構造９の側壁内空気通路２９から上方へ屋根裏空間３１へ流れる冷気の風量を調節する為に、ダクト部材３４の上端より上方の位置において、外壁２７に形成された開口部を開閉可能で上方への風量を調節可能なドア部材４０が設けられ、このドア部材４０は電動アクチュエータにより回動駆動されて開度調節可能である。
Since the second embodiment is an example in which the exhaust cooling air utilization cooling system of the CO 2 refrigerant heat pump water heater of the first embodiment is partially changed, only the changed portion will be described.
As shown in FIG. 6, the outer wall 27 is formed at a position above the upper end of the duct member 34 in order to adjust the amount of cool air flowing upward from the air passage 29 in the side wall of the second-floor side wall structure 9 to the attic space 31. A door member 40 that can open and close the opened opening and adjust the air volume upward is provided, and the door member 40 is rotationally driven by an electric actuator to adjust the opening.
こうして、ドア部材４０の開度を図示の１００％の状態から０％の状態まで連続的に調節することができ、２階部分３を冷房する冷房能力を調節することができる。そして、非冷房時には、ドア部材４０の開度を０％にしておいてもよい。尚、ドア部材４０とその電動アクチュエータが第１風量調節手段に相当する。 Thus, the opening degree of the door member 40 can be continuously adjusted from the 100% state to the 0% state shown in the figure, and the cooling capacity for cooling the second floor portion 3 can be adjusted. And at the time of non-cooling, you may make the opening degree of the door member 40 0%. The door member 40 and its electric actuator correspond to the first air volume adjusting means.
同様に、２階側壁構造９の側壁内空気通路２９から下方へ天井裏空間２５へ流れる冷気の風量を調節する為に、ダクト部材３４の下端付近において、外壁２７に形成された開口部を開閉可能で下方への風量を調節可能なドア部材４１が設けられ、このドア部材４１は電動アクチュエータにより回動駆動されて開度調節可能になっている。こうして、ドア部材４１の開度を図示の１００％の状態から０％の状態まで連続的に調節することができ、１階部分２を冷房する冷房能力を調節することができる。そして、非冷房時には、ドア部材４１の開度を０％にしておいてもよい。尚、ドア部材４１とその電動アクチュエータが第２風量調節手段に相当する。 Similarly, an opening formed in the outer wall 27 is opened and closed near the lower end of the duct member 34 in order to adjust the amount of cool air flowing downward from the air passage 29 in the side wall of the second-floor side wall structure 9 to the ceiling space 25. A door member 41 capable of adjusting the downward air volume is provided, and the door member 41 is rotationally driven by an electric actuator so that the opening degree can be adjusted. In this way, the opening degree of the door member 41 can be continuously adjusted from the 100% state to the 0% state shown in the figure, and the cooling capacity for cooling the first floor portion 2 can be adjusted. And at the time of non-cooling, you may make the opening degree of the door member 41 0%. The door member 41 and its electric actuator correspond to second air volume adjusting means.
さらに、ヒートポンプ式給湯機３２の内部のファンの加圧能力が十分でない場合に給湯機３２の排気抵抗が増加しないように、ダクト部材３４の出口側の上端付近の側壁内空気通路２９内には、冷気の風圧を高めて上方へ押し出す為の小型の電動ファン４２（第１ファン手段）が配設されている。同様に、ダクト部材３４の出口側の下端付近の側壁内空気通路２９内には、冷気の風圧を高めて下方へ押し出す為の小型の電動ファン４３（第２ファン手段）が配設されている。尚、ファンとしてシロッコファンを採用してもよい。 Furthermore, in the air passage 29 in the side wall near the upper end on the outlet side of the duct member 34, the exhaust resistance of the water heater 32 is not increased when the pressure of the fan inside the heat pump hot water heater 32 is not sufficient. A small electric fan 42 (first fan means) is disposed to increase the wind pressure of the cold air and push it upward. Similarly, in the side wall air passage 29 near the lower end on the outlet side of the duct member 34, a small electric fan 43 (second fan means) for increasing the wind pressure of the cold air and pushing it downward is disposed. . A sirocco fan may be adopted as the fan.
尚、前記実施例１，２は、２階建て構造の建物に本考案を適用した場合を例にして説明したが、１階建て構造の建物に本考案を同様に適用することができる。また、前記ダクト部材３４の構造は一例を示すものであり、当業者であれば、本考案の趣旨を逸脱することなく、前記実施例に種々の変更を不可した形態で実施することができる。 In addition, although the said Example 1, 2 demonstrated taking the case of applying this invention to the building of 2 stories structure, it can apply this invention similarly to the building of 1 stories structure. Further, the structure of the duct member 34 shows an example, and those skilled in the art can implement the embodiment in a form in which various modifications cannot be made without departing from the spirit of the present invention.
