• an air duct extending between said air intake ports and said air discharge port in said indoor machine housing,
• at least two heat exchangers provided in the air duct and having a front heat exchanger placed on a side of the front face of the housing and a rear heat exchanger placed on a side of the rear face of the housing
• an air fan provide in the air duct, and
• a lamp box placed between upper ends of said front heat exchanger and said rear heat exchanger, said lamp box having an ultraviolet lamp device, an air inlet and an air outlet, said ultraviolet lamp device emitting first ultraviolet light with waveband of 250 to 260 nm having an effect of removing airborne microorganisms and second ultraviolet light with waveband of 100 to 220 nm having an effect of decomposing odor components contained in air to deodorize the air, a part of air sucked from said air intake ports to enter into said indoor machine housing passing through the lamp box to thereby remove airborne microorganisms and deodorize the air by the first and second ultraviolet lights, and being supplied to said rear heat exchanger from said air outlet.
