Device for Controlling the capacity of a Variable Capacity Compressor, an air conditioning system of an automobile

摘要

The present Invention relates to a device for Controlling the capacity of Variable Capacity Compressor, an air conditioning system of an automobileIt has an Evaporator and a Changer of Compressor capacity,Apparatus comprising a First Temperature Detector arranged on the Evaporator to detect a First Air Temperature At The Inlet of the Evaporator; a Second Temperatu detectorRa provided behind the Evaporator to detect a Second Air Temperature At the Evaporator Outlet Temperature Detector; a Third set in the Outer compartment of AutomobileL to identify a Third Outdoor Air Temperature in the compartment and a control to control the Exchanger CapacityControl which includes: a First Comparator for Comparing a First Predetermined temperature with the temperature of the air and provide a first control Signal; a Second Comparator PA Second Predetermined temperature to compare with the first air temperature in response to the comparison using the first Comparator and the absence of the first control Signal; a terCer Comparator for Comparing a Third Predetermined temperature with the temperature of the air and provide a Third control Signal; a Fourth Comparator for Comparing a Fourth TempeThe Third Predetermined temperature with air temperature in response to the comparison through the Third Comparator and the presence of the Third control signal and a Fourth Signal provideControlA Fifth Comparator for Comparing the second Predetermined temperature with the temperature of the air and provide a Fifth control Signal; and a Comparator for Comparing the fifth you sectoMperatura default with the second air temperature in response to the comparison by the fifth Comparator and the absence of the fifth Signal controlWith the Sixth Sixth Comparator provides a control Signal; and a Comparator for Comparing the Sixth Seventh with the second Predetermined temperature in response to air temperature.Action by the Sixth Comparator and the presence of the Sixth control Signal; The Seventh Seventh Comparator provides a control Signal; a Comparator which compares a Seventh Eighth temperatureDefault with the second air temperature and provides a control signal that Eighth Ninth Eighth; Comparator that compares a Second Predetermined temperature with the temperature of the aIRe in response to the comparison by the Comparator and the absence of the eighth Octave control Signal; The Ninth Ninth Comparator provides a control Signal.
