PURPOSE:To improve the heat collecting efficiency of an air conditioner by a method wherein a coil heated by the solar heat as a heat source and a humidifier are connected in series with a total heat exchanger so that the open air is heated by the solar heat. CONSTITUTION:The open air enters a total heat exchanger 1 from an air duct 11, is heated as a result of its heat exchange with exhaust air flowing through an air duct 14 and enters a solar coil 2. At the same time, water heated by a solar heat collector 4 is stored in a heat storage tank 5 and is supplied to the solar coil 2 through a pipe (b) and to the solar humidifier 3 through a pipe (c) by the operation of a hot water circulation pump 7. Accordingly, the hot water from the total heat exchanger 1 is heated further by the solar coil 2, humidified by the humidifier 3 and supplied to an air handling unit 10 from which the hot water is distributed into a chamber 12 so as to serve for heating. On the other hand, in case where a cooling operation is performed, the hot water in the heat storage tank 5 is supplied to an absorbing type refrigerator 8 so as to make itself cold water which is then supplied to the solar coil 2 through a cold water circulation passage (f) so as to cool the open air 11. As a result, it is possible to improve the heat collecting efficiency of the air conditioner.
