<P>PROBLEM TO BE SOLVED: To allow inverter integrated-type electric compressors with a single specification to be usable irrespective of sorts of a refrigerant. <P>SOLUTION: The inverter integrated-type electric compressor including an inverter control software that is installed with a function of estimating a discharge temperature of a refrigerant based on the calculation from a variety of parameter values, stores a function of receiving a signal indicating a sort of a refrigerant transmitted from a vehicle and a calculation software compatible with at least two sorts or more of refrigerant properties that may be supplied from the vehicle, selects the calculation software according to the sort of refrigerant received from the vehicle to estimate a discharge temperature by the selected calculation software. A discharge temperature can be estimated while corresponding to each refrigerant even in using two or more sorts of different refrigerants in an identical inverter integrated-type electric compressor, thereby eliminating the need of using a variety of different inverter integrated-type electric compressors according to sorts of refrigerant and preventing an increase in models and maintenance cost of the inverter integrated-type electric compressor. <P>COPYRIGHT: (C)2013,JPO&INPIT |
