Air-conditioning system utilizing natural energy and building using the same

Abstract

To provide air-conditioning system which can air-condition a room with low electric power regardless of day or night by cooling outside air by using natural energy and efficiently storing the coldness in a thermal storage material while cooling the room with the cooled outside air and whose construction cost is low. Air-conditioning system utilizing natural energy is characterized by comprising a thermal storage chamber (27) formed under the floor; an intake air storage section (4) provided adjacently to the thermal storage chamber (27); an intake pipe (5) connected to the intake air storage section (4) and adapted for sucking outside air; an outside air cooling mechanism for cooling the outside air sucked through the intake pipe by using natural energy; an outside air supply pipe (7) for introducing the outside air cooled by the outside air cooling mechanism into the thermal storage chamber (27); a blower (8) for feeding the outside air cooled by the outside air cooling mechanism into the outside air supply pipe (7); and thermal storage material (6) housed in the thermal storage chamber and adapted for storing or releasing the coldness, and characterized in that the average particle diameter of the thermal storage material (6) is largeras the depth from a bottom surface (7a) of the thermal storage chamber (27) to a floor surface (20) is greater.

Description

technical field [0001] The present invention relates to an air conditioner capable of mainly utilizing natural energy for all buildings such as residences, offices, factories, schools, meeting places, public facilities, poultry houses, and agricultural greenhouses, and buildings using the same Adjust the indoor air temperature. Background technique [0002] Conventionally, an air-conditioning system has been proposed that regulates the temperature in a building using geothermal heat or the like maintained at a substantially constant temperature throughout the year. [0003] Next, the "air-conditioning system utilizing natural power of a building" related to the conventional art will be described. [0004] The "air-conditioning system using natural force of a building" described in Patent Document 1 includes: an underground pipe, a pebble layer for storing geothermal heat and conducting the stored geothermal heat to air from the outside or in the building, and The undergrou...

AI Technical Summary

Problems solved by technology

[0008] In addition, there is also the following problem: In order to allow the cold air to enter every corner under the floor, it is necessary to form a complicated pipe structure under the floor, and the construction requires cost.
