Abstract
PURPOSE:To narrow the measurement range and then increase the solution by securing virtually the same detection temperature region for each temperature sensor in the heat pump type air-conditioner or the like. CONSTITUTION:The intra-room temperature, the intra-room heat exchange temperature, the out-of-room temperature and the out-of-room heat exchange temperature are detected each by temperature sensors S1-S4. At the same time, the measurement range of each sensor features 20-30 deg.C, 20-33 deg.C, -15--10 deg.C and -20-10 deg.C respectively, and the measurement range width features 53 degrees at -20-33 deg.C. And the value of resistances R3 and R4 are set less than the value of resistances R1 and R2, and the measurement range of each sensor becomes 20- 30 deg.C, 20-33 deg.C, 5-30 deg.C and 0-30 deg.C respectively if the bias levels of sensors S3 and S4 are increased by 20 deg.C. As a result, the detection temperature region becomes identical virtually for each sensor, and the measurement range width becomes 33 degrees at 0-33 deg.C.
