Document Type and Number:
WIPO Patent Application WO/2018/109798
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an air conditioning system for a highly airtight and highly heat-insulating house, the system being capable of forming a stable living space in a winter season and also forming a stable living space in a summer season in a highly heat-insulating and highly airtight house. The system is configured to include: a heat storage airtight tank formed in the ground; an underfloor airtight chamber formed on the heat storage airtight tank; and a room airtight space which is formed on the underfloor airtight chamber, and the side surface of which is surrounded by a wall surface airtight layer, and moreover on the top surface of which a ceiling airtight layer is disposed. The room airtight space has an air supply port for supplying air sent from an air control unit formed on the ceiling airtight layer to the room airtight space. The room airtight space communicates with a passage vertically passing through a partitioning wall, which defines the room airtight space, by passing-ports formed on upper and lower end portions of the partitioning wall. The passage in the partitioning wall communicates with the underfloor airtight chamber formed by a floor material and a base constituting the lower part of the room airtight space. The underfloor airtight chamber communicates with the heat storage airtight tank through an underground duct provided in the base. The heat storage airtight tank communicates with the air control unit which has a heat exchanger and a cooling machine, and which is disposed in an attic space on the top surface of the ceiling airtight layer through an exhaust duct disposed in a ventilating layer formed in the wall body constituting the room airtight space. A part of exhausted air that has been introduced in the air control unit from the heat storage airtight tank through the exhaust duct is discharged to the outside of a building through the heat exchanger. Outside air corresponding to the amount of the exhausted air is introduced into the air control unit through the heat exchanger. The air control unit supplies air, of which humidity, temperature, and pressure have been adjusted, to the room airtight space through the air supply port.
