PROBLEM TO BE SOLVED: To keep temperature safety in the vicinity of a heater while suppressing abnormal noise by improving the positional relationship of a deodor heater and the shape of a thermal insulation board thereby suppressing the surface temperature of the deodor heater at the time of heating operation. SOLUTION: Position of a deodor heater 3 is separated by 29 mm or longer from a heating time refrigerant inlet piping 5 arranged for the front heat exchanger 7 in a heat exchanger 2. Consequently, surface temperature rise of the deodor heater 3 can be suppressed during conduction of thereof at the time of heating operation even for a machine rank having heating capacity of 3.6 kW or above. In the positional relationship of a thermal insulation board 4 and the deodor heater 3, forward end part of the board 4 is projecting forward by 5 mm FROM the vertical line of the heater 3. According to the arrangement, abnormal noise caused by the high temperature air flow on the periphery of the heater 3 and the rotation of a cross-flow fan 1 can be controlled from low wind region to high wind region during conduction of the deodor heater 3. |
