Abstract: Indoor air conditioner units are manufactured by pre-assembling evaporators and supplying the evaporators to a plurality of unit assembling stations, whereby at each unit assembling station, the evaporators are assembled with other air conditioner elements to form finished indoor air conditioner units. The evaporators can be assembled at an evaporator assembling station which supplies all of the unit assembling stations with evaporators. Alternatively, the evaporators can be assembled at each of the unit assembling stations.

Abstract: A noise tester for testing an operating noise level of an indoor air conditioner includes a casing which is installed between an assembly line for assembling the air conditioner unit, and a packing line for packing the assembled unit. The casing includes a bottom section and a cover removably mounted on the bottom section for opening the casing and permitting a unit to be introduced therein. A receiving part is disposed in the bottom section for receiving a unit from the assembly line when the cover is open, and for transferring the unit to the packing line after the testing has been performed. A test mechanism is provided for testing and operating noise level of a unit disposed in the casing with the cover closed. The test mechanism includes a microphone disposed within the casing.
