PURPOSE:To improve rising-up performance as well as the feeling of room heating by a method wherein room temperature is detected and is compared with set temperature at every given time to switch the air-flow amount of an indoor side fan. CONSTITUTION:Immediately after the starting of room heating operation, the detecting temperature T from a room temperature thermistor 1 is lower than the set temperature T0 and the output L from a comparating circuit 3 is inputted into a micro-computer 4. The micro-computer 4 takes the input from the comparating circuit 3 at every given time n0 thereinto and in case an electric signal is L, a signal to a relay circuit 5 becomes OFF, the indoor side fan is operated through the contact SHi, in which the flow amount of the indoor side fan is large and the increasing speed of the room temperature is quickened. When the room temperature is increased and the detecting temperature T has exceeded the set temperature T0, the output of the comparating circuit 3 becomes H, the relay is switched to the contact Hi 5b, in which the flow amount is small, and the fan is operated under the condition Hi. Whereby the capacity of the room heating is restricted somewhat and the room heating operation is switched to the same making much of the feeling of the room heating. |
