JPS56138636A - Heat exchanging type ventilating device - Google Patents

Abstract

PURPOSE:To improve utilization of the space of a living room, to unnecessitate reinforcement of the surrounding portion of a part of fixture and to improve heat-exchanging and ventilating efficiencies as well as the dust-collecting ratio by oroviding an air suction port and an exhaust port on the indoor side in the surface of a floor and by fitting the heat exchanging type ventilating device to the part under the floor. CONSTITUTION:The air suction port 10 and the exhaust port 27 on the indoor side are provided at grilles 12 and 28 situated at the same level with the surface 11 of the floor, respectively, while the main body 32 of the ventilating device having a heat exchanger 14, as well as an air suction port 22 and an exhaust port 19 for outdoor use, is fitted to the part under the floor. The air inside the living room enters the main body 32 from the air suction port 10 and after dust being removed therefrom by a filter 13, gives thermal energy to the suction air at the heat exchanger 14. Then, is passes through the exhaust port 19 and a ventilating port 21 via an orifice 15 and is exhausted. On the other hand, the air under the floor 23 enters a dust 33 from an opening 34, where it is given the thermal energy in the ground 35, enters further the main body 32 from the air suction port 22, is given the thermal energy at the heat exchanger 14 and then is sent into the living room from the exhaust port 27.
