Abstract
Abstract A cooling-fan controlling apparatus for an air conditioner system including a variable volume compressor, including a work-performed detecting device for detecting the work performed by the variable volume compressor, a discharge-pressure detecting device for detecting the pressure discharged from said compressor, and a controller for controlling the drive speed of a cooling fan on the basis of both the values detected in said work-performed detecting device and said discharge pressure detecting device.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
63 words
A cooling-fan controlling apparatus for an air conditioner system including a variable volume compressor, comprising: work-performed detecting means for detecting the work performed by the variable volume compressor; a condenser; a cooling fan for cooling said condenser; and a control means for controlling the drive speed of said cooling fan on the basis of the value detected in said work performed detecting means.
Claim 2
Dependent Claim
63 words
A cooling-fan controlling apparatus for an air conditioner system including a variable volume compressor, comprising: work-performed detecting means for detecting the work performed by the variable volume compressor; a condenser; a cooling fan for cooling said condenser; and a control means for controlling the drive speed of said cooling fan on the basis of the value detected in said work performed detecting means.
Claim 3
Dependent Claim
28 words
The apparatus as set forth in claim 1 wherein said work performed by the variable volume compressor is represented by a quantity of refrigerant discharged from the compressor.
Claim 4
Dependent Claim
48 words
The apparatus as set forth in claim 2, wherein said variable volume compressor is of a swashplate-type having a swashplate and said quantity of refrigerant discharged is determined by an angle of inclination of said swashplate and a number of rotations of a drive shaft for the swashplate.
Claim 5
Dependent Claim
79 words
A cooling-fan controlling apparatus for an air conditioner system including a variable volume compressor, comprising: work-performed detecting means for detecting the work performed by the variable volume compressor; a condenser; a cooling fan for cooling said condenser; discharge-pressure detecting means for detecting the pressure discharged from said compressor; and control means for controlling the drive speed of said cooling fan on the basis of both the values detected in said workperformed detecting means and said discharged pressure detecting means.
Claim 6
Dependent Claim
79 words
A cooling-fan controlling apparatus for an air conditioner system including a variable volume compressor, comprising: work-performed detecting means for detecting the work performed by the variable volume compressor; a condenser; a cooling fan for cooling said condenser; discharge-pressure detecting means for detecting the pressure discharged from said compressor; and control means for controlling the drive speed of said cooling fan on the basis of both the values detected in said workperformed detecting means and said discharged pressure detecting means.
Claim 7
Dependent Claim
28 words
The apparatus as set forth in claim 4 wherein said work performed by the variable volume compressor is represented by a quantity of refrigerant discharged from the compressor.
Claim 8
Dependent Claim
49 words
The apparatus as set forth in claim 5, wherein said variable volume compressor is of a swashplate type having a swashplate and said quantity of refrigerant discharged is determined by an angle of inclination of said swashplate and a number of rotation of a drive shaft for the swashplate.
