Problems solved by technology

One problem with UV purifier systems is that the UV lamps consume energy
Also, since the UV light from such purifiers is extremely harmful to human eyesight, people cannot safely check UV lights at work
As a result, it can be difficult to know when a light source has failed to disable the purifier, especially if the air conditioner is not visible to the end user

example

[0038] An example of an IAQ board 100 in a preferred embodiment that plugs into an air regulator board as a plug-in in an IAQ option (IOB) printed circuit board (PCB) 700 is now described in more detail using a block diagram and an exemplary printed circuit board. 103. Figure 7 The block diagram of the IOB 700 shows the input and output (I / O). 24V alternating current (AC) power is supplied to the IOB printed circuit board via electrical connectors for, for example, proportional fresh air dampers, CO 2 Sensors and devices such as TVOC / humidity sensors. 230V AC power is provided through another connector to the IOB to power external devices such as secondary fresh air dampers and UV lamps. Here, most of the input and output functions of sensors and controlled devices are provided on the IOB printed circuit board 700, and comparison and control functions are provided on the air conditioner control board 103 ( Figure 7 not shown in ) provided. The IOB printed circuit board 7...

Abstract

An air conditioning system to improve indoor air quality (IAQ) comprises an air conditioner to receive indoor air from an indoor space and to heat or cool the air, the air conditioner to then return conditioned air to the indoor space. An IAQ option board (IOB), electrically coupled to the air conditioner control board, is configured to accept electrical inputs from at least one IAQ sensor. A fresh air damper is electrically connected to the IOB, the IOB controlling the position of the fresh air damper valve. An air purifier is situated such that air from the indoor space passes through the purifier. The operation of state of operation of the purifier is based at least in part on the input from at least one IAQ sensor to improve the IAQ of the indoor space.

Description

technical field [0001] The present invention relates generally to the control of indoor air quality, and more particularly to the control of levels of carbon dioxide, volatile organic compounds, and other airborne pollutants in the breathable air of interior building spaces. Background technique [0002] Indoor Air Quality (IAQ) refers to the quality of breathable air in indoor living and working spaces. Indoor carbon dioxide (CO 2 ) levels, volatile organic compounds (VOCs) and other airborne organic substances, including bacteria, will worsen the IAQ of a given indoor breathing space. Although air conditioning systems (also known as comfort systems, including heating and cooling functions) are commonly used in residential and office buildings today, the control of factors detrimental to IAQ remains problematic. Although most interior spaces are sealed to some extent to improve heating and air-conditioning efficiency, some efforts have been made to deliberately draw a cer...
