  The above problem-solving means is a smart eco air conditioning system including an air conditioner, an embedded pipe, a wind pressure valve, and a wind pressure shutter, and the outside air (OA) is formed by laying a pipe buried horizontally in the ground by the operation of the fan of the outdoor unit. The air conditioning unit covers the outdoor unit and takes it into the outdoor unit box adjacent to the building. The 24-hour ventilation air is taken into the outdoor unit box from the wind pressure valve installed in the building, and the air inside the outdoor unit box is exhausted to the atmosphere. In order to improve and improve the thermal efficiency of the outdoor unit and to reduce the amount of air sucked by the fan of the outdoor unit, outside air is directly taken into the outdoor unit box from the wind pressure shutter installed in the outdoor unit box.

図面の説明図１は本発明の実施形態を示す構成面図である。　　　図２は本発明のブロック形状の形態を示す比較面図である。図３は本発明の穴開きブロックを配置した構成面図である。DESCRIPTION OF THE DRAWINGS FIG. 1 is a structural view showing an embodiment of the present invention. FIG. 2 is a comparative view showing the block shape of the present invention. FIG. 3 is a structural view in which the perforated blocks of the present invention are arranged.

以下、本発明の実施形態を図１～図3に基づいて説明する。
　　　本発明は建物100を図１に示す。建物100の地下に埋設管6を埋設し、室外機ボックス103に室外機２と風圧弁４と風圧シャッター5を施工し、建物100に室内機1と２４時間換気扇3と床下に蓄熱層104を施工した２４時間換気空調システムである。
　　　この発明の室外機ボックス103は、室外機2の吸込み側と吹出し側以外を覆い、建物100に隣接し(又はビルトイン)、室外機2のファンの作動により、外気空気と排気空気を室外機2の吸込み側に取り込み、吹出し側から大気に排気するためのボックスである。
　　　この発明の蓄熱層104は土間上部と基礎側面に断熱材を施工し、その土間の断熱材の上に穴開きブロック7（図２－(c)）を交互に配置施工（図３）し、さらに鉄筋入りの土間コンクリートを施工することにより、四方八方、給気(ＳＡ)空気が抵抗少なく循環し、均一に蓄熱することが可能となる。従来の蓄熱層に使用するブロックは図２－(a)（基本ブロック）や図２－(b)（横筋ブロック）であり、図２－(a)の基本ブロックを配置した場合は、交互に配置した面の空気の通過面積がブロック中心の穴に対して50％なり、空気循環抵抗が大きくなる。また、図２－(b)の横筋ブロックを配置した場合は、交互に配置した面のみの空気通過経路となり、蓄熱する表面積が30％以下となる。本発明である穴開きブロック7（図２－(c)）は、ブロック中心の３個の穴を貫通し、３方向の側面が半円になっているために、交互に配置（図３）した場合に、ブロック中心の３個の穴と側面の穴が同じ大きさになり、均一に蓄熱を蓄えることが可能となる。
この発明の実施形態に示す図１において、上記の様に構成された地熱利用の蓄熱型２４時間空調システムについて説明する。まず建物100は、屋根や外壁、基礎などは高断熱工法を採用し、窓は２重ガラス（Low-E）を採用した高気密高断熱の全館24時間換気空調システム構造が望ましい。
この発明の全館24時間換気空調システムが設置した建物100において、埋設管6は建物100の地下、又は建物100の平行に深さ１ｍ以上横長く、外気ボックス102から室外機ボックス103まで埋設する。室外機2のファンの風力を利用し、まず、外気空気（OA）Aは外気ボックス（フィルター付き）102から、埋設管6に吸い込まれ、地中熱の熱交換により、予冷暖房空気Bになり、室外機ボックス内103に取り入れ、室外機ボックス103内の空気を排気することにより、室外機2の熱交換率を大幅に改善向上することが可能となる。たとえば真夏の外気空気（OA）Aが32℃の場合において、地下1.5ｍの地中温度は約19℃前後であり、予冷房空気Bは30℃前後となり、約－2℃前後冷やされた空気により、室外機2の冷房効率を向上することが可能となる。真冬場の外気空気（OA）Aが0℃の場合においては、地下1.5ｍの地中温度は約15℃前後であり、予暖房空気Bが約+2℃前後暖められ、室外機2の暖房効率を向上することが可能となる。
さらに、室外機2のファンの風力により、建物100に設置した風圧弁4から排気される排気空気（EA）Cは室外機ボックス103内に取り入れられ、さらに室外機2は室外機ボックス103内の空気を排気することにより、室外機2の熱交換率を大幅に改善向上することが可能となる。たとえば、真夏の外気空気（OA）Aが32℃の場合において、建物内101の空調した排気空気（EA）Cは、27℃前後であり、－5℃前後冷たい空気が排気され、真冬場の外気空気（OA）Aが0℃の場合において、建物内101の空調した排気空気（EA）Cは、20℃前後であり、+20℃前後暖かい空気が排気され、室外機2内の熱交換機を経由して大気に排気する。排気空気量が150Φダクトの場合、外気空気（OA）Aに対して約±2℃前後、室外機2の冷暖房効率を向上することが可能となる。なお、室外機2のインバーターによるファンの変動により、室外機ボックス103内の吸込み量が不足の場合、室外機ボックス103に取り付けた風圧シャッター5が作動し、外気空気（OA）Aを直接取り込み、いずれも、すべて室外機2のファンの作動により、室外機ボックス103内の気圧が変化し、風圧弁4及び風圧シャッター5がファジーに開閉する。
　外気空気(OA) Aに対して、地熱利用において、±2℃の温度変化と、排気空気(EA) Cを利用して、±2℃の温度変化との合計±4℃温度が変動することになり、室外機2の熱交換率を大幅に改善向上することが可能となる。従来においては、室外機2は、夏には熱い空気を取り入れ、冬は冷たい空気を取り入れるために、室外機2の冷暖房効率が悪い。特に、冬は室外機2内に熱交換器に霜が附着し、自動霜取装置が作動し、無駄な電力を使用している。
一方、室内機1に於いては、２４時間換気システムとして、室内機1のファンの風力を利用し、外気空気（OA）Aは外気ボックス（フィルター付き）102から、埋設管6に吸い込まれ、地中熱の熱交換により、予冷暖房空気Bになり、室内機1に取り入れ、室内機1から室内101の吹出し、室内101の温度変化を抑制する。室外機2が停止時には換気扇3が作動し、室外機2が作動時には、24時間換気扇3を停止することが可能となり、節電なる。たとえば真夏の外気空気（OA）Aが32℃の場合において、地下1.5ｍの地中温度は約19℃前後であり、予冷房空気Bは30℃前後となり、約－2℃前後冷やされた空気により、室内機１の冷房効率を向上することが可能となる。真冬場の外気空気（OA）Aが0℃の場合においては、地下1.5ｍの地中温度は約15℃前後であり、予暖房空気Bが約+2℃前後暖められる。
さらに、室内機1に於いては、還気空気(RA)Dと上記２４時間換気システム用予冷暖房空気Bを室内機１が空調し、給気空気(SA)Eを蓄熱層104の下部から吹き出し、敷き詰まられた穴開きブロック７の内部を蓄熱しながら通過し、さらに室内101の床から数か所、室内101に吹き出す。基本的には、深夜電力を利用し、深夜にエアコン（室内機１、室外機2）運転し、蓄熱層104に蓄熱し、日中は送風運転し、蓄熱した熱を活用する。また、蓄熱層104により、１階の床がすべて床冷暖房となることにより、エアコンの熱効率が向上する。建物100の状況により、三相三線式動力電力を必要となり場合がある、深夜電力を利用し、蓄熱をすることにより、大幅な節電効果がある。
さらに、太陽光発電パネルやエコ給湯器などと組合せて施工することにより、より省エネでかつ健康住宅が完成する。
  Hereinafter, embodiments of the present invention will be described with reference to FIGS.
The present invention shows a building 100 in FIG. The underground pipe 6 is embedded in the basement of the building 100, the outdoor unit 2, the wind pressure valve 4 and the wind pressure shutter 5 are installed in the outdoor unit box 103, the indoor unit 1 and the 24-hour ventilation fan 3 in the building 100 and the heat storage layer 104 under the floor. This is a 24-hour ventilation air conditioning system.
The outdoor unit box 103 of the present invention covers other than the suction side and the blow-out side of the outdoor unit 2, is adjacent to the building 100 (or built-in), and operates the fan of the outdoor unit 2 to send outdoor air and exhaust air to the outdoor unit 2 It is a box for taking in to the suction side and exhausting to the atmosphere from the blow-out side.
In the heat storage layer 104 of the present invention, a heat insulating material is applied to the upper part of the soil and the side of the foundation, and the perforated blocks 7 (FIG. 2- (c)) are alternately arranged on the heat insulating material of the soil (FIG. 3). Furthermore, by constructing the concrete with reinforcing bars, the air supply (SA) air circulates with less resistance in all directions, and heat can be uniformly stored. The blocks used in the conventional heat storage layer are shown in Fig. 2- (a) (basic block) and Fig. 2- (b) (horizontal stripe block). The air passage area on the arranged surface is 50% with respect to the hole in the center of the block, and the air circulation resistance is increased. In addition, when the horizontal stripe block of FIG. 2- (b) is arranged, it becomes an air passage route of only the alternately arranged surfaces, and the heat storage surface area is 30% or less. The perforated block 7 according to the present invention (FIG. 2- (c)) passes through the three holes at the center of the block and the side surfaces in three directions are semicircular, so that they are alternately arranged (FIG. 3). In this case, the three holes in the center of the block and the holes on the side face have the same size, and it is possible to store heat uniformly.
In FIG. 1 shown in the embodiment of the present invention, a geothermal heat storage type 24-hour air conditioning system configured as described above will be described. First of all, it is desirable that the building 100 has a highly airtight and highly insulated whole building 24-hour ventilation air conditioning system structure that uses a high thermal insulation method for roofs, outer walls, foundations, etc. and double glass (Low-E) for windows.
In the building 100 in which the whole building 24-hour ventilation air conditioning system of the present invention is installed, the buried pipe 6 is buried in the basement of the building 100 or in parallel with the building 100 from the outside air box 102 to the outdoor unit box 103 at a depth of 1 m or more. Using the wind power of the fan of the outdoor unit 2, first, the outside air (OA) A is sucked into the buried pipe 6 from the outside air box (with filter) 102, and becomes precooled heating air B by heat exchange of the underground heat The heat exchange rate of the outdoor unit 2 can be greatly improved and improved by taking it into the outdoor unit box 103 and exhausting the air inside the outdoor unit box 103. For example, when the outdoor air (OA) A in midsummer is 32 ° C, the underground temperature of 1.5m underground is around 19 ° C, the pre-cooling air B is around 30 ° C, and the air cooled around -2 ° C. Thus, the cooling efficiency of the outdoor unit 2 can be improved. When the outdoor air (OA) A in midwinter is 0 ° C, the underground temperature of 1.5m underground is around 15 ° C, and the preheating air B is warmed around + 2 ° C, heating the outdoor unit 2 Efficiency can be improved.
Further, the exhaust air (EA) C exhausted from the wind pressure valve 4 installed in the building 100 is taken into the outdoor unit box 103 by the wind of the fan of the outdoor unit 2, and the outdoor unit 2 is further stored in the outdoor unit box 103. By exhausting air, the heat exchange rate of the outdoor unit 2 can be greatly improved and improved. For example, when the midsummer outdoor air (OA) A is 32 ° C, the air-conditioned exhaust air (EA) C in the building 101 is around 27 ° C, and cold air around -5 ° C is exhausted. When the outside air (OA) A is 0 ° C, the air-conditioned exhaust air (EA) C in the building 101 is around 20 ° C, warm air around + 20 ° C is exhausted, and the heat exchanger in the outdoor unit 2 To the atmosphere via When the amount of exhaust air is 150Φ duct, it is possible to improve the cooling / heating efficiency of the outdoor unit 2 around about ± 2 ° C with respect to the outside air (OA) A. If the suction amount in the outdoor unit box 103 is insufficient due to fan fluctuations due to the inverter of the outdoor unit 2, the wind pressure shutter 5 attached to the outdoor unit box 103 is activated and directly takes in the outside air (OA) A, In any case, the air pressure in the outdoor unit box 103 is changed by the operation of the fan of the outdoor unit 2, and the wind pressure valve 4 and the wind pressure shutter 5 are opened and closed in a fuzzy manner.
With respect to the outside air (OA) A, the total ± 4 ° C temperature of the temperature change of ± 2 ° C when using geothermal heat and the temperature change of ± 2 ° C using the exhaust air (EA) C should fluctuate. Thus, the heat exchange rate of the outdoor unit 2 can be greatly improved and improved. Conventionally, the outdoor unit 2 takes in hot air in summer and takes in cold air in winter, so that the efficiency of the outdoor unit 2 is poor. In particular, in winter, frost is attached to the heat exchanger in the outdoor unit 2, the automatic defrosting device is activated, and wasteful power is used.
On the other hand, the indoor unit 1 uses the wind power of the fan of the indoor unit 1 as a 24-hour ventilation system, and outside air (OA) A is sucked into the buried pipe 6 from the outside air box (with filter) 102, By exchanging the geothermal heat, it becomes precooled heating air B, which is taken into the indoor unit 1 and blows out the indoor 101 from the indoor unit 1 and suppresses temperature changes in the indoor 101. When the outdoor unit 2 is stopped, the ventilation fan 3 is operated. When the outdoor unit 2 is operated, the ventilation fan 3 can be stopped for 24 hours, thereby saving power. For example, when the outdoor air (OA) A in midsummer is 32 ° C, the underground temperature of 1.5m underground is around 19 ° C, the pre-cooling air B is around 30 ° C, and the air cooled around -2 ° C. As a result, the cooling efficiency of the indoor unit 1 can be improved. When the outdoor air (OA) A in mid-winter is 0 ° C, the underground temperature of 1.5m underground is around 15 ° C, and the preheating air B is warmed around + 2 ° C.
Further, in the indoor unit 1, the indoor unit 1 air-conditions the return air (RA) D and the pre-cooling heating air B for the 24-hour ventilation system, and supplies the supply air (SA) E from the lower part of the heat storage layer 104. It passes through the inside of the perforated block 7 which is blown out and spread, while accumulating heat, and blows out from the floor of the room 101 to the room 101 at several places. Basically, it uses midnight power, operates an air conditioner (indoor unit 1, outdoor unit 2) at midnight, stores heat in the heat storage layer 104, and blows air during the day to use the stored heat. In addition, the heat storage layer 104 improves the thermal efficiency of the air conditioner by floor heating / cooling all the floors on the first floor. Depending on the situation of the building 100, three-phase three-wire motive power may be required. By using midnight power and storing heat, there is a significant power saving effect.
Furthermore, by constructing it in combination with solar power generation panels and eco water heaters, energy-saving and healthy housing will be completed.
