Abstract
Abstract A drive control apparatus for controlling the operation of an air conditioner comprises a 24-hour air-conditioning mode, a selector for selecting one of drive and release positions of the 24-hour air-conditioning mode, a load-responsive air-conditioning mode under which the air conditioner is operated in dependence on a load in a space to be air-conditioned, a drive control for effecting one of drive and stop controls of the load-responsive air-conditioning mode, and a preferential output unit for outputting a signal from the drive control in preference to an output signal from the selector. An output from the preferential output unit may be used to drive the operating frequency of the compressor at a predetermined number of revolution, to drive an indoor fan either continuously or intermittently at a predetermined number of revolution, and/or to deflect a vertical deflector blade to a predetermined position.

Claim 1
Independent Claim
85 words
A drive control apparatus for an air conditioner, which comprises: a selector means for selecting one of drive and release positions of a 24-hour air-conditioning mode; a drive control means for effecting one of drive and stop controls of a load-responsive air-conditioning mode under which the air conditioner is operated in dependence on a load in a space to be air-conditioned; and a preferential output means for outputting a signal from the drive control means in preference to an output signal from the selector means.
Claim 2
Dependent Claim
85 words
A drive control apparatus for an air conditioner, which comprises: a selector means for selecting one of drive and release positions of a 24-hour air-conditioning mode; a drive control means for effecting one of drive and stop controls of a load-responsive air-conditioning mode under which the air conditioner is operated in dependence on a load in a space to be air-conditioned; and a preferential output means for outputting a signal from the drive control means in preference to an output signal from the selector means.
Claim 3
Dependent Claim
179 words
An air conditioner which comprises: a drive control apparatus including a 24-hour air-conditioning mode, a selector means for selecting one of drive and release positions of the 24-hour air-conditioning mode, a load-responsive air-conditioning mode under which the air conditioner is operated in dependence on a load in a space to be air-conditioned, a drive control means for effecting one of drive and stop controls of the load-responsive air-conditioning mode, and a preferential output means for outputting a signal from the drive control means in preference to an output signal from the selector means; an indoor unit including an indoor heat exchanger and an indoor fan; a compressor for compressing a coolant, said compressor constituting a refrigerating cycle together with the indoor heat exchanger and an outdoor heat exchanger; a mode detecting means for detecting that the 24-hour air-conditioning mode has been detected by a signal from the preferential output means; an output means operable in response to an electric signal from the mode detecting means to drive an operating frequency of the compressor at a predetermined number of revolution.
Claim 4
Dependent Claim
179 words
An air conditioner which comprises: a drive control apparatus including a 24-hour air-conditioning mode, a selector means for selecting one of drive and release positions of the 24-hour air-conditioning mode, a load-responsive air-conditioning mode under which the air conditioner is operated in dependence on a load in a space to be air-conditioned, a drive control means for effecting one of drive and stop controls of the load-responsive air-conditioning mode, and a preferential output means for outputting a signal from the drive control means in preference to an output signal from the selector means; an indoor unit including an indoor heat exchanger and an indoor fan; a compressor for compressing a coolant, said compressor constituting a refrigerating cycle together with the indoor heat exchanger and an outdoor heat exchanger; a mode detecting means for detecting that the 24-hour air-conditioning mode has been detected by a signal from the preferential output means; an output means operable in response to an electric signal from the mode detecting means to drive an operating frequency of the compressor at a predetermined number of revolution.
Claim 5
