<P>PROBLEM TO BE SOLVED: To provide a heating apparatus that has high heating performance and small heat loss, and is suitable for central air conditioning. <P>SOLUTION: The heating apparatus is equipped with a fan coil 30 with a fan and a heat exchanger, a suction device 50, a blowout device 60, and ducts 71 and 72 in a space under a floor. A heating medium heated by a boiler 39 heats circulating air to heat the space under the floor, and then heats the whole floor to heat the living space. The blowout device 60 which blows out hot air to the space under the floor includes a blowout housing where a distance between an upper surface and a lower surface gradually decreases toward an outlet and a distance between both side surfaces gradually increases toward the outlet. The blowout device 60 blows out hot air to a flow passage area formed between the floor and a partition member 81. Guides 85, 85A, and 85B arranged on the partition member 81 smoothly disperse the hot air. With this structure, the hot air blown out from the blowout device 60 generates a turbulent flow in a wide area right below the floor to significantly increase the heating performance and to significantly reduce the heat loss. <P>COPYRIGHT: (C)2012,JPO&INPIT |
