However, when operating a cooling device or a heating device, fossil energy such as gas and oil is wasted, and it is a problem to give a load to the global environment.

In order to solve this problem, a technique is disclosed in which water is stored in a room temperature cooling and heating water tank, the room temperature is adjusted using the specific heat of water, and fossil energy used for air conditioning is saved (for example, Patent Document 1). reference.).
JP-A-5-296575

  In the conventional technology described above, a room temperature cooling / heating water tank is buried in the ground, a pipe for conveying air is arranged inside the room temperature cooling / heating water tank, and heat is exchanged between the stored water and the conveyance air in the room temperature cooling / heating water tank. As a result, the carrier air is cooled or heated, and is used for indoor cooling or heating.

  However, according to this prior art, it is necessary to embed the room temperature cooling / heating water tank in the ground, and the water in the room temperature cooling / heating water tank must be managed, which may be troublesome and costly.

  In view of the above-described problems, an object of the present invention is to provide a room temperature adjustment system that can adjust indoor temperature by using natural energy instead of fossil energy without labor and cost.

  In order to achieve the above object, the present invention is characterized by (a) an outside air intake port for taking outdoor outside air into the room, and (b) a temperature management device for heating the outside air taken in from the outside air intake port by sunlight. , (C) a temperature change pipe embedded in the ground through which the outside air heated by the temperature control device passes, and (d) a room temperature adjustment provided with an air outlet for blowing the outside air after passing through the temperature change pipe into the room The gist is that it is a system.

  According to the room temperature adjustment system according to the feature of the present invention, the outside air heated by sunlight warms the soil around the temperature change pipe, and the residual heat blows out into the room, so that the room can be warmed. This is suitable for using the room temperature adjustment system as heating during the winter day.

  In addition, when the outside air that has not been heated by the temperature control device passes through the temperature change pipe, the room temperature adjustment system warms the outside air by the soil around the temperature change pipe, and the air blower vents the warm outside air into the room. It is preferable to blow out.

  The soil around the temperature change pipe is warmed by the outside air heated by sunlight passing through the temperature change pipe. It is warmed by the soil around the change pipe and can be used as room heating.

  Moreover, it is preferable to further include a preheating precooling tube that passes outside air that has not been heated by the temperature management device before passing through the temperature changing tube and preheats the outside air by using the surrounding soil.

  Since the underground temperature at a depth of 4 to 5 m in the recent state of Tokyo is 16 to 17 ° C., before the outside air is blown to the temperature change pipe, the outside air is warmed in advance with a preheating precooling pipe. Thereby, it is possible to prevent the hot soil around the temperature change pipe from being cooled as much as possible.

  In addition, the temperature management device has a metal heat collecting plate inside, and cools the outside air taken in from the outside using the radiation cooling phenomenon of the heat collecting plate, and the temperature change pipe is cooled by the temperature management device. It is preferable that the outside air passed through.

  According to this room temperature adjustment system, the outside air cooled by the radiation cooling phenomenon cools the soil around the temperature change pipe, and the remaining heat blows out into the room, so that the room can be cooled. This is suitable for using the room temperature adjustment system as cooling at night in summer.

  In addition, when the outside air that has not been cooled by the temperature management device passes through the temperature change pipe, it is preferable that the outside air is cooled by the soil around the temperature change pipe, and the air outlet blows the cooled outside air into the room.

  The soil around the temperature change pipe is cooled by the outside air cooled by the radiative cooling phenomenon passing through the temperature change pipe. Therefore, when the outside air is taken in during the summer, the outside air is cooled to the temperature change pipe. It is cooled by the surrounding soil and can be used for indoor cooling.

  Further, it is preferable that the preheating precooling pipe passes outside air that has not been cooled by the temperature management device before passing through the temperature changing pipe, and precools the outside air using surrounding soil.

  As described above, since the underground temperature at a depth of 4 to 5 m in the state of Tokyo is 16 to 17 ° C., the outside air is cooled in advance with a preheating precooling tube before the outside air is blown to the temperature change tube. Thereby, it is possible to prevent the low temperature soil around the temperature change pipe from being heated as much as possible.

  According to the present invention, it is possible to provide a room temperature adjustment system that adjusts the indoor temperature by using natural energy instead of fossil energy without labor and cost.

  On the other hand, during the summer, low temperature ambient air at night is sent into the temperature management device, the outside air is cooled using the radiation cooling phenomenon of the aluminum heat collecting plate installed in the temperature management device, and the low temperature air is cooled to the ground temperature. By sending it to the change pipe, the soil in the ground is artificially recooled to create a low temperature soil. And by using and storing the heat storage and heat insulation properties of the soil, cooling air is stably supplied and used as cooling.
