<P>PROBLEM TO BE SOLVED: To provide an under-floor air conditioner that supplies cool and warm air produced by a heat pump utilizing low-cost night power to an under-floor space and actualizes low-cost air conditioning by radiation heat from a floor board without causing uneven indoor temperature. <P>SOLUTION: The under-floor air conditioner is configured to supply cooled or heated air produced by a liquid- or refrigerant-based heat pump using night power not only to the under-floor space through a duct by a forced circulation machine but also to a vent hole A arranged in a floor structure member of a closed space formed of a floor board and a floor structure member by a suction operation of an agitation type blower, wherein an air pressure of the closed space is made lower than that of the under-floor space and the cool and warm air of the under-floor air is drawn into the closed space from a vent hole B, the floor board and the energy storage material or the like of the closed space is cooled or heated for heat accumulation, the air of the closed space is supplied to the under-floor space by the agitation type blower, a circulation path returning to the forced circulation machine after convection and heat radiation is formed, and the cooled or heated air is supplied to the closed space and under-floor space. <P>COPYRIGHT: (C)2013,JPO&INPIT |
