RADIATION AIR CONDITIONING SYSTEM

PROBLEM TO BE SOLVED: To provide a radiation air-conditioning system capable of improving health aspect by preventing contaminant such as dust under the ceiling from being supplied indoors, shortening an initial rise time in cooling and heating operation, and improving comfort. SOLUTION: As this radiation air conditioning system comprises an indoor air-conditioning means capable of performing indoor air-conditioning and a radiation air-conditioning means capable of performing radiation air-conditioning respectively as exclusive air conditioners of the air conditioning means, the contaminant is not supplied indoors. Further a wind direction changing blade is disposed at a cooling/heating air supply outlet portion of the indoor air-conditioning means, and the wind direction is set to supply the cooling/heating air along a wall by the Coanda effect when the indoor air conditioning means is operated. Thus the heat of the cooling/heating air and the heat of the wall are exchanged, the indoor air-conditioning by radiation and the cooling/heating airflow by convection are mixed to perform the indoor air-conditioning. When the comfortable indoor temperature is achieved, the indoor air-conditioning is switched to the radiation air-conditioning. COPYRIGHT: (C)2008,JPO&INPIT
