In heating, a fossil fuel such as coal or oil, a stove using charcoal or firewood, a heater using electric power, or the like is common. In cooling, there are not as many types as heating systems. The main ones are electric fans and heat pump type air conditioners.

本発明では、給気口より空気循環パイプに空気を圧送し、これと同時に送風口から定温状態の空気が室内に送出される。そして、外気の高い温度を熱伝導率の高い金属製の空気循環パイプを介してコンクリート塊及び空気循環パイプの径方向に放射状に貫通して設けられた複数の伝熱管に伝導させる。これによりコンクリート塊及び伝熱管の温度が上昇し、循環パイプ内で空気の対流が起こり地中温度と空気温度が平衡し定温状態となる。   In the present invention, air is pumped from the air supply port to the air circulation pipe, and at the same time, air at a constant temperature is sent from the air blowing port to the room. Then, a high temperature of the outside air is conducted to a plurality of heat transfer tubes provided radially through the concrete lump and the air circulation pipe through a metal air circulation pipe having a high thermal conductivity. As a result, the temperature of the concrete block and the heat transfer tube rises, air convection occurs in the circulation pipe, and the underground temperature and the air temperature are balanced and become a constant temperature state.

次に、本発明の実施の形態を図面に示す実施例に基づいて説明する。
図１は本発明に係る冷暖房空調装置を地中に埋設した状態を示す側面図、図２は図１のＡ−Ａ線断面図、図３は本発明に係る空気循環パイプの要部平面図、図４は図３のＢ−Ｂ線断面図である。 Next, embodiments of the present invention will be described based on examples shown in the drawings.

It also contributes to a significant reduction in the consumption of fossil fuels, which are the main cause of air pollution. In addition, power consumption can be significantly reduced.

また、一旦埋設すると半永久的に利用可能で、ランニングコストも極端に削減でき、直接、間接の大気汚染防止、また、火力も用いないため二酸化炭素や一酸化炭素中毒になる危険もなく、省エネルギー効果を果たすのみでなく安全である。   In addition, once buried, it can be used semipermanently, running costs can be drastically reduced, direct and indirect air pollution prevention, and no thermal power is used, so there is no danger of carbon dioxide and carbon monoxide poisoning, and energy saving effect It is safe as well as fulfilling.

尚、本発明は上記実施例に限定されず、種々の応用変形が可能である。例えば、補助給気機としてエアコンに連結し省エネ化を図ることもできる。   In addition, this invention is not limited to the said Example, A various application deformation | transformation is possible. For example, it can be connected to an air conditioner as an auxiliary air supply device to save energy.
