Abstract
An air conditioner generally comprises a compressor accommodated in the outer casing thereof and the compressor is surrounded by a sound-proof cover. The sound-proof cover is formed of a main body made of a sound absorbing material and a heat insulating member preferably made of a foam of a thermosetting resin which is bonded to the surface of the main body opposing to the outer surface of the compressor. The heat insulating member has a heat transfer efficiency smaller than that of the main body. The main body is preferably formed of a sound absorbing member and a noise insulating member. The heat insulating member, the sound absorbing member and the noise insulating member are laminated and bonded to each other in this order. The entire sound-proof cover is arranged in contact with substantially the entire outer periphery of the compressor. An outer casing formed of a sound absorbing material may be further disposed so as to surround the sound-proof cover with space therebetween.
