Description

  The present invention relates to a cooling / heating air conditioner, and more particularly, to a subsurface constant-temperature use cooling / heating air conditioner that can save energy by utilizing a constant underground temperature.

  Various technologies related to air conditioning and air conditioning exist. 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 generally used. In cooling, there are not as many types as heating systems. The main ones are electric fans and heat pump type air conditioners.

  The air conditioning apparatus as described above requires a lot of electric power, and the apparatus itself, installation cost, running cost, etc. increase. Therefore, for example, a cooling device (for example, see Patent Document 1) using the cooling temperature of groundwater has been proposed.

Japanese Patent Laid-Open No. 6-347065 (pages 2-6, FIG. 1)

  However, when such an apparatus is used for a livestock house or a house, it is necessary to further facilitate the construction, reduce the cost, increase the efficiency of cooling, and the like. The present invention has been made in view of the above-mentioned problems, and its purpose is to save energy, facilitate construction, reduce costs, increase cooling efficiency, and directly and indirectly have a conventional air conditioning system. Air pollution, the high-cost situation of power-utilizing air conditioning systems, and the reduction of various natural environments caused by combustion-type heating systems.

  In order to solve the above-mentioned problems, the present inventor has found that a constant temperature under the ground, which is substantially constant throughout the seasons, in particular, a temperature constant under 3 m below ground, preferably below 5 m is utilized. For this reason, the present invention is characterized in that it comprises a concrete block buried underground and an air circulation pipe embedded in the concrete block, and a plurality of heat transfer tubes in the radial direction of the air circulation pipe. The second feature is that the slabs are provided so as to penetrate radially, and the third feature is that the embedding depth of the concrete block is at least 3 m below the ground.

The present invention has the following excellent effects.
(1) By using a constant temperature of 3 m or less below the ground, which is 11 to 14 ° C. in winter and 7 to 11 ° C. in summer, the temperature is 25 to 35 ° C. in summer and the temperature is −5 to 10 ° C. in winter. The outside air temperature can be transferred to a temperature range (7 to 14 ° C.) centered on the underground temperature in summer and winter and blown indoors. 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.
(2) Once buried, it can be used semi-permanently, running costs can be drastically reduced, direct and indirect air pollution prevention, and since no thermal power is used, there is no danger of carbon dioxide and carbon monoxide poisoning, saving energy It is safe as well as effective.
(3) The structure is simple and can be manufactured at low cost.

  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.

Next, embodiments of the present invention will be described based on examples shown in the drawings.
FIG. 1 is a side view showing a state in which an air-conditioning / air-conditioning apparatus according to the present invention is buried in the ground, FIG. 2 is a cross-sectional view taken along line AA in FIG. 1, and FIG. 4 is a cross-sectional view taken along line BB in FIG.

  As shown in FIGS. 1 to 3, the air-conditioning / air-conditioning apparatus of the present embodiment is composed of a concrete lump 1 embedded in the underground G and an air circulation pipe 2 embedded in the concrete lump 1. The air circulation pipe 2 is formed in a straight tube shape in the horizontal direction, and a plurality of heat transfer tubes 3 in which aluminum pipes are filled with mortar concrete are provided in a radial direction in the radial direction of the air circulation pipe 2.

  Here, the heat transfer tubes 3 are fixed in a staggered manner with a phase of 45 degrees with respect to the longitudinal direction of the air circulation pipe 2. An air supply 5 for supplying outside air from the riser 4 and an air outlet 6 are provided. In this case, the riser 4 can be connected also to the blower opening 6. The air conditioner is embedded in the ground at a depth of at least 3 m below the ground. As a material of the air circulation pipe 2 and the heat transfer tube 3, aluminum having high thermal conductivity and strong against corrosion is suitable.

  The air circulation pipe 2 is buried together with the concrete 1 placed in the excavation pit. Then, air is pumped from the air supply port 5 to the air circulation pipe 2, and at the same time, air at a constant temperature is sent from the air blowing port 6 into the room. That is, the temperature of the outside air is conducted to the concrete 1 placed through the air circulation pipe 2. As a result, convection of air occurs in the air circulation pipe 2, and the underground temperature and the air temperature are balanced and become a constant temperature state.

  And by the above configuration, by utilizing a constant temperature state of 3 m or less underground, preferably 5 m or less, that is 11 to 14 ° C. in winter and around 7 to 11 ° C. in summer, the temperature is 25 to 35 ° C. in summer and the temperature in winter The outside air temperature of −5 ° C. to 10 ° C. can be transferred to a temperature zone (7 to 14 ° C.) centered on the underground temperature in summer and winter and blown indoors. 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.

  Also, once buried, it can be used semi-permanently, 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.

  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.
