Description

  The present invention relates to an air conditioner, and more particularly to an air conditioner that can regulate air taken from an air intake.

  In general, the underground temperature is almost constant throughout the year, being lower than the outside air in the summer and higher than the outside in the winter. For this reason, in recent years, it has been considered to effectively use the underground temperature (geothermal).

  For example, an air blast pipe called a cool tube is buried in the ground of a building, and the outside air is passed through the air blast pipe to allow heat exchange between the outside air and the temperature in the ground, thereby adjusting the temperature inside the building. A room temperature adjustment system is disclosed (see, for example, Patent Document 1).

Specifically, this room temperature adjustment system takes in outside air from an air intake port that is one end of an air blowing pipe arranged outdoors, and cools or heats the outside air at the other end of the air blowing pipe at the other end of the air blowing pipe. By blowing out from a certain air outlet, the temperature in the room can be lowered or raised.
