Abstract

A complete system for indoor air pollution control and its components is disclosed herein, incorporating a furnace, heat pump or the like for supplying conditioned air to a room or zone via a duct network. Air filters are removably disposed at exhaust vents leading into the room or zone and intake vents are included for drawing air away from the room or zone for re-circulation. Ambient air intake vents are included in the duct network and the network is suitable for multiple level buildings. The system further includes sensing circuits within the duct work or zone which tests or senses the air for multiple characteristics of air quality and a panel having a variety of displays portrays the results of the individual characteristics being monitored. Such characteristics of air quality include ozone, carbon monoxide, nitrogen dioxide, etc.

Claims

1. A complete air purification and conditioning system for indoor air pollution control comprising:

a duct network interconnecting opposite ends of a room for circulating air therethrough;

inlet and outlet registers terminating the opposite ends of said duct network in opposing relationship at opposite ends of said room;

said duct network further having air-conditioning means for altering the condition of the air circulating through said duct network;

sensing circuit means within said duct network for testing or sensing the air for multiple chemical characteristics of air quality;

display means operably coupled to said sensing circuit means for portraying the results of the individual characteristics of air quality;

said display means includes a variety of individual air quality visual displays that include display of characteristics such as ozone, carbon monoxide, and nitrogen dioxide;

said display means is disposed within said room and said sensing means are disposed within said duct network;

said air circulation via duct network is responsive to said chemical sensing circuit means to assure a constant level of clean air within said room by means of a 10% room air volume exchange rate;

said chemical sensing circuit means includes a separate sensor for each chemical air quality characteristic and a separate display for displaying each chemical air quality characteristic;

a signal processing circuit interconnecting each sensor with its respective display for a given chemical air quality characteristic;

said signal processing circuit including calibration means and a smog alert display;

said calibration means and smog alert display being connected in parallel with other air sensors and displays in said system;

means connected to said sensing circuit means responsive to said sensors for setting control levels for energizing said smog display;

an air intake connected to said duct network for introducing ambient air to said system; and

said air-conditioning means responsive to said sensing circuit means coupled thereto in conjunction with said display means for cooperatively altering the condition of the air circulating through said duct network and for dynamically displaying the altered chemical condition thereof.
