PURPOSE: To match with the change in environment and obtain comfortable dwelling condition by a method wherein before the detection of temp. zones indoor humidity is detected and a mode with dehumidifying operation or a mode without dehumidifying operation is selected.
CONSTITUTION: When automatic operation is commanded by a remote controller 10, an indoor fan 14 and an outdoor fan 18 are ON and humidity is detected by an indoor humidity detecting element 5 and when the humidity is 60% or more, a mode A is obtained and when less than 60%, a mode B is obtained. At the mode A an indoor and outdoor temp. are detected by detecting elements 3, 16 and it is judged that the required conditions correspond to which zones of space cooling, dehumidification, monitoring, and space heating in the mode A. Similarly, at the mode B, it is judged that the required conditions correspond to which zones of space cooling, monitoring, and space heating without dehumidification. For instance, in case of 70% humidity, 22°C indoor temp., and 20°C outdoor temp., the required condition is judged to be in the dehumidification zone of the mode A at a set circuit 7 for switchover of zones and this data is stored into a RAM 13 through a control part 13 and dehumidifying operation is started. The situation is the same for the mode B. In 15 minutes after the temp. detection, the fans 14, 18 are ON again and indoor humidity, indoor temp., and outdoor temp. are detected again.
