PURPOSE:To make the indoor temperature distribution ideal with more warmth around the lower part of the body than the upper part by a method wherein an indoor machine capable of switching the outlet for air according to heat or cooling is provided, the indoor machine is made to communicate with the void in a double floor, openings are formed in the ceiling board as passage through which the ceiling chamber communicates with the room, and openings are formed in the double floor as passages connecting the void to the room. CONSTITUTION:In heating, a fan 23 rotates in the normal direction; the indoor air is sucked through openings-ceiling 31 and into an upper outlet 28, and by undergoing heat exchange at a heat exchanger 21, the air turns to warm air. The warmed air flows into an air duct 26 through a connection port 25 and is conveyed through a lower outlet 30 to a void 14 in a double floor 5; through openings-in-floor 15 bored in the double floor 5 the warmed air is ejected into the room, mainly into a living region 6 therein, at very low air speed. The warmed air thus ejected warms the living region 6 and then flows through openings-in-ceiling 31 into a ceiling chamber 16 and sucked into the upper outlet 28. In coding, the fan 23 rotates in reverse so that the indoor air is sucked through the openings-in-floor 15 into the void 14; then through the lower outlet 30 into the air duct 26, and through the connection port 25 into the indoor machine 19. |
