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...

Examples

example 2

[0289] In New York, U.S.A., the maximum daytime temperature in summer is about 32° C. and the relative humidity is 53%, so it cannot be expected to achieve a sufficient cooling effect of the outside air by utilizing the heat of vaporization of water.

[0290] On the other hand, since the temperature in the ground is 12 to 13°C at a point 4 to 5 m underground, cold air is supplied from the suction pipe 5 at night with the spraying device 9 stopped, and is transmitted to the heat exchange pipe 13 for the ground heat. The outside air is sufficiently cooled by geothermal heat, and the cooled outside air is used to store the heat storage material 6 in advance, so that the outside air can be cooled by the heat storage material 6 with cooling ability during the day when the temperature rises to cool the room. 11.

[0291] In this way, it is not necessary to necessarily install the spraying device 9 in an area with high relative humidity during a high temperature period, especially wh...

example 3

[0294] In Sandanski, Bulgaria, the highest temperature in summer is about 44° C. and the relative humidity is about 35%, so it cannot be expected to achieve a sufficient cooling effect of the outside air by utilizing the heat of vaporization of water.

[0295] On the contrary, since the temperature in the ground at the place of 4-5m underground is 13-14°C, it is the same as the case of New York in the above-mentioned U.S., so it is not necessary to install the spraying device 9 in the air-conditioning equipment 2 utilizing natural energy in this embodiment, There is an effect that the room 11 can be maintained at a comfortable temperature without consuming a large amount of power due to the high cooling effect of the outside air by geothermal heat and the high heat storage effect by the heat storage material 6 .
