Abstract
Energy saving in indoor air conditioning is achieved by combining indoor air vertical convection producing means and indoor air conditioning means. A fan for performing suction and exhaust of air for vertically circulating the indoor air through suction and exhaust ports provided on upper and lower parts of a room is operated or stopped according to a difference in temperatures detected on the upper and lower parts of the room. The output of the fan at the time of operation is increased or decreased according thereto to prevent energy loss occurring when warm air accumulates on the upper part and cool air accumulates on the lower part. The operation or suspension of an air conditioner installed indoors, and the amount of energy consumed at the time of operating the air conditioner is controlled depending on a difference between a temperature detected in the room and a preset indoor temperature.
