IPC: F24F11/02
Filed: 1995-03-31
Abstract: PURPOSE: To prevent an air conditioning capability of a specified indoor device from being decreased by a method wherein when a required capability of an indoor device during its operation exceeds a capacity of an indoor device, set room temperatures of other indoor devices except a pre-selected indoor device operated preferentially are increased during cooling operation, and in turn when a heating operation is carried out, the set room temperature is decreased.

In the case that indoor devices 3B and 3C having an intermediate preferential order are operated, refrigerant supplying amount for them is reduced a little lower than a present refrigerant supplying amount and in the case that the indoor devices 3D and 3E have the lowest preferential order, a controlling operation for making a operator reduction of refrigerant supplying amount than the present refrigerant supplying amount is carried out.  In this way, when a requisite capability of the indoor device being operated exceeds a capacity of the outdoor device 1, a flow rate of refrigerant circulated and supplied to other indoor devices except the pre-selected indoor device preferentially operated is reduced and an amount of refrigerant in the preferential indoor device is assured, so that it is possible to prevent an air conditioning capability from being reduced in the preferential operated indoor device.

Abstract: PURPOSE:To improve the fuel consumption by controlling driving of an electromagnetic clutch, based on both a detected value and a pre-set value of a rotor speed, thereby relieving the degree of impact the time of connection and disconnection of a supercharger. CONSTITUTION:When a by-pass valve 23 is closed while an electromagnetic clutch 17 connected to the output side of an ECU 20 is turned OFF, the rotor of a supercharger 16 runs idly because of passage of intake-air. When the rotor speed detected by a detecting sensor 82 is higher than the rotor speed corresponding to the engine speed which is set in advance, the electromagnetic clutch 17 is turned ON to operate the supercharger 16. On the other hand, when the rotor speed which is detected while the electromagnetic clutch 17 is turned ON, is lower than the rotor speed corresponding to the engine speed, which is set in advance, the electromagnetic clutch 17 is turned OFF to stop the supercharger 16. With this contrivance, the degree of impact at the time when the electromagnetic clutch is connected or disconnected can be relieved, and at the same time both engine output and fuel consumption can be enhanced.
