The abnormality analyzer 4 analyzes the alarm signal 15 from the V/F converter 19 and judges the abnormality of a power amplifier 10. Thus, the abnormality of the detector with built-in power amplifier can be found out. Further, since the number of signal lines can be decreased, the weight and cost of cables can be reduced by half, and reliability can be improved.

Abstract: PURPOSE:To effectively lower a temperature of the air to be supplied to a room to be air conditioned by a simple structure. CONSTITUTION:Part of the air of a room 1 to be air conditioned is discharged to a circulation air exhaust passage 9 connected to the room 1. Fresh air introduced into an atmospheric air introduction passage 6 and circulation air discharged from the room 1 to the passage 9 are combined in an air passage connector 8. The combined air flow is cooled by a plurality of heat exchangers 10, 14, 15. The exchanger 10 of the exchangers 10, 14, 15 is a heat exchanger for heat exchanging between the combined air and the circulation air. Since the circulation air is discharged from the room 1, its temperature is about the temperature (about 17-25 deg.C) of the room 1. Thus, the air (combined air) to be supplied to the room 1 is effectively cooled by the circulation air of low temperature (17-25 deg.C).
