PURPOSE:To enable uniform distribution of room temperature thereby increasing the heating effect in a residencial space by providing a means to start operation with low-speed air flow, then supplying high-speed air flow for a certain period of time, and thereafter supplying high-spped air flow intermittently. CONSTITUTION:A control circuit consists of a microprocessor or the like 3 which starts heating operation with low-speed air, then carrying out high-speed blow for a certain period of time and thereafter carrying out high-speed blow intermittently and which also sends the revolution speed control signal to a blower drive circuit 4 of a blower 5 in accordance with a predetermined program. Thereby, the blow-out speed is reduced because of low-speed operation and also the heated air accumulated near the ceiling surface because of short reach can be blown away enabling uniform distribution of room temperatures. |
