Abstract
Abstract An air quality conditioning system for adjusting an environmental air quality in an accommodation space comprises; a detection device (1) for detecting the air quality; another detection device (2) for detecting the temperature and humidity; a signal processor (3) for identifying the causes for the change in the air quality of the accommodation space based on the outputs of said detection devices (1,2), and also determining the degree of the change based on the discomfort degree data for the air quality, with another function of correcting the outputs of said detection means (2) for the temperature and humidity.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
125 words
An air quality conditioning system comprising: an air quality detection device (1) for detecting the air quality constituted with at least three factors of (i) the presence of a human occupant in an accommodation space, (ii) smoking and (iii) background odor, and outputting detection signals; a signal processor (3) for identifying the cause for change in the air quality based on the output signals issued from said air quality detection device, determining the degree of the change in the air quality based on a threshold discomfort data for the air quality, and issuing processed signals; and a control device for (4) controlling the operation of an air conditioning apparatus (5) which comprises at least an air conditioner, ventilator, air cleaner based on the processed signals.
Claim 2
Dependent Claim
49 words
The air quality conditioning system in accordance with claim 1, wherein; said air quality detection device (1) includes a sensor for detecting carbon dioxide, and said signal processor (3) is for determining the presence of human occupant in the accommodation space based on the output signal from said sensor.
Claim 3
Dependent Claim
59 words
The air quality conditioning system in accordance with claim 1, wherein; said air quality detection device (1) comprises at least one of a sensor for detecting carbon monoxide and a sensor for detecting hydrogen, and said signal processor (3) is for determining a state of the smoking in the accommodation space, based on the output signal from said sensor.
Claim 4
Dependent Claim
68 words
The air quality conditioning system in accordance with claim 1, wherein; said air quality detection device (1) comprises at least one of a sensor for detecting organic solvents, a sensor for detecting volatile nitrogen-containing compounds and a sensor for detecting volatile sulfur-containing compounds, and said signal processor (3) is for determining a state of background odor in the accommodation space, based on the output signal from said sensor.
