<p><P>PROBLEM TO BE SOLVED: To provide a device of a simple, robust and compact constitution for controlling a fixed capacity compressor capable of being inexpensively manufactured, being easily installed to heating, ventilation and/or air-conditioning unit of an automobile, and saving energy required for driving a compressor. <P>SOLUTION: In this device 13 for controlling the fixed capacity compressor 9 connected with an evaporator 12 in which airflow 3 passes, the compressor 9 and the evaporator 12 constitute an air-conditioning loop 8. The device 13 includes measuring gages 15 and 16, and a comparison means 14 for comparing a measured value VM to be a characteristic C of fluid FR and A with at least two thresholds VSmin and VSmax of the characteristic C. The device 13 also includes an upstream temperature gage 20 for measuring an upstream temperature T2 of the airflow 3 and supplying an information item 18 for determining the thresholds VSmin and VSmax of the characteristic C. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
