AIR CONDITIONING SYSTEM FOR DOME-SHAPED BUILDING HAVING DOUBLE MEMBRANE ROOF STRUCTURE

摘要

PROBLEM TO BE SOLVED: To decrease temperature gradient in a main space within a building and reduce maintenance control cost by providing an air conditioning facility for heating the main space of a dome-shaped building having a double membrane roof structure with air-conditioned air lines for a roof for supplying air- conditioned air between double membranes of the roof. ;SOLUTION: A dome-shaped building 1 has a roof 2 having double membranes and a main space 3 in which events and the like are held. A first air passage 5 is formed at a lower peripheral part of a floor 4 of the main space 3 and a second air passage 6 having an air conditioner 7 for heating is formed at an upper peripheral part. Warm air from the air conditioner 7 is allowed to flow only into air-conditioned air lines 9a, 9b for the main space from common discharge lines 8a, 8b, and is not allowed to flow into air-conditioned air lines 10a, 10b for the roof. Therefore, the warm air is blown into the first ail passage 5 and is diffused into the main space 3 through an outlet 15 for heating so as to uniformize temperatures in the main space 3. Condensation on faces of the membranes of the roof 2 is prevented from occurring, by permitting the warm air to flow into the air-conditioned air line 10a for the roof.;COPYRIGHT: (C)1999,JPO
