<p><P>PROBLEM TO BE SOLVED: To provide a ventilation air conditioning device capable of performing a defrosting operation while continuing the heating of a bathroom 3 even during the defrosting operation, to solve a problem that a heating operation cannot be continued because of the frost formation of the moisture in the air on a surface of an evaporator 24 when the heating operation is continued for a long time in a state that the temperature of air supplied to the evaporator 24 is low in a ventilation air conditioning device used in the bathroom 3, a dressing room 4 and the like. <P>SOLUTION: A second suction opening 33 is formed at a ventilation air conditioner body 6, so that the frost on a surface of the evaporator 24 is melted by successively supplying air in the bathroom 3 sucked from the second suction opening 33 to the evaporator 24 and a condenser 20 in a defrosting operation. A suction opening 16 is provided with a first damper 29, and the first damper is closed in the defrosting operation, so that air in the bathroom 3 is sucked from the second suction opening 33. Furthermore, a defrosting damper 32 is disposed in a defrosting air trunk 31 communicating with the first air trunk 19 and the second air trunk 22, and is opened only at the defrosting operation to switch the flow channels in the defrosting operation. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
