Patent number: 5148685Abstract: In an air conditioner including a variable-capacity compressor, a control system performs a PI calculation based on a temperature deviation between the actual temperature of the air downstream of an evaporator and its target temperature, thereby determining a control amount for controlling the capacity of the compressor. It is judged whether or not the sum of a proportional control component and an integral control component exceeds a limit value of the control amount corresponding to the maximum capacity of the compressor. If this judgment is in the affirmative, an ordinary integral calculation is stopped, and the integral control component is determined by subtracting the proportional control component from this limit value.Type: GrantFiled: May 31, 1991Date of Patent: September 22, 1992Assignee: Zexel CorporationInventors: Akihiko Takano, Yoshihiko Sakurai, Katsumi Iida

Patent number: 5074123Abstract: An air conditioning control system for an automotive vehicle having an internal combustion engine. A variable capacity compressor has a pump having displacement thereof variable in response to a change in pressure within a controlled pressure chamber, a communication passage communicating between a low pressure chamber and the controlled pressure chamber, and a valve disposed to vary an opening area of the communication passage. An electromagnetic clutch connects and disconnects the compressor to and from the engine. An evaporator is connected to the compressor. A control unit controls the capacity of the compressor by supplying the valve with control current normally set within a predetermined range, to vary the opening area of the communication passage such that the temperature of outlet air from the evaporator becomes equal to a desired value.Type: GrantFiled: October 16, 1990Date of Patent: December 24, 1991Assignees: Zexel Corporation, Mazda Motor CorporationInventors: Katsumi Iida, Yoshihiko Sakurai, Akihiko Takano, Shigetoshi Doi, Taketoshi Matsushita
