Abstract
Abstract An air conditioning system which includes a plurality of internal air conditioning units, a plurality of external refrigerating circuit units for executing refrigerating cycle operations, each external refrigerating circuit unit including a fluid path control valve whose activation is audible, and a plurality of corresponding relationship check switches respectively provided in the internal air conditioning units. When the corresponding relationship check switch of one of the internal air conditioning units is operated, the fluid path control valve of the corresponding external refrigerating circuit unit generates an audible sound, intermittently.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
101 words
An air conditioning apparatus comprising: external refrigerating circuit unit means for executing a refrigerating cycle operation; fluid path control valve means, provided in the external refrigerating circuit unit means, for controlling the path of a fluid, the fluid path control valve means producing an audible sound when energized; internal air conditioning unit means associated with the external refrigerating circuit unit means for generating a flow of conditioned air; and corresponding relationship check means for outputting an operation command signal to intermittently energize the fluid path control valve means thereby intermittently producing the audible sound from the fluid path control valve means.
Claim 2
Dependent Claim
101 words
An air conditioning apparatus comprising: external refrigerating circuit unit means for executing a refrigerating cycle operation; fluid path control valve means, provided in the external refrigerating circuit unit means, for controlling the path of a fluid, the fluid path control valve means producing an audible sound when energized; internal air conditioning unit means associated with the external refrigerating circuit unit means for generating a flow of conditioned air; and corresponding relationship check means for outputting an operation command signal to intermittently energize the fluid path control valve means thereby intermittently producing the audible sound from the fluid path control valve means.
Claim 3
Dependent Claim
17 words
An apparatus according to claim 1, wherein the fluid path control valve means includes a four-way valve.
Claim 4
Dependent Claim
17 words
An apparatus according to claim 1, wherein the fluid path control valve means includes an open/close valve.
Claim 5
Dependent Claim
44 words
