| Head's takes the consultative approach when selling
indoor air quality add-ons and upgrades. The basic aim is to offer
these solutions for: health reasons, cleanliness reasons and comfort
reasons. First an analysis is made from test results provided
by an AirAdvice monitor. The monitor measures the following:
- Temperature- where levels that are above 81°F is considered
"above the recommended range" and less than 68.5°F daily average is
"below the recommended range".
- Relative Humidity- where levels greater than 55% daily
average is "higher than the recommended maximum and less than the 25%
daily average is "below the recommended average".
- Particulates Matter - has a reporting threshold where
greater than 40 ug/m³ sustained for one hour or more is "elevated" by
measuring particles between 2.5 and 7 microns in size.
- Carbon Monoxide- is considered "elevated" when the level is
greater than 25 PPM for one hour.
- Total Volatile Organic Compounds- with levels above 400 ug/m³
is considered "moderately elevated" and above 750 ug/m³ is
"significantly elevated".
Any recommendation uses the four basic IAQ solution strategies as
recommended by the US Environmental Protection Agency. Different
equipment is used to address the specific problems discovered by the
exploratory process to offer a "Whole House" solution.
- Eliminate- According to the EPA the best
method of improving IAQ is with source control.
- Ventilate- The second best method to
improve IAQ is by improving the ventilation in the space.
Energy Recovery Ventilators are used with high-efficient total
enthalpy heat exchanger cores.
Humidifiers and De-humidifiers are provided as a standalone unit or
installed in the air conditioning system with controls and fill/drain
handling devices built in.
3. Clean- Filtration for
Particulates/Allergens
Pleated MERV 8 for residential and MERV 11 for commercial units are
used with filter depths up to 5" to reduce pressure drop.
Self-contained HEPA filters with integral fans ducted into the return
air are used in addition to the pre-filter for additional cleanliness.
Purification for Bioaerosols and Microorganisms
UV lights constantly irradiating the wet side of cooling coils and
multiple UV lights in the return air plenum are used to reduce
bioaerosols and improve heat exchange efficiency.
Oxidation for Chemical Gases, Odor Control and Volatile
Organic Compounds.
Photocatalytic Oxidation and Photohydroionization™ devices are
installed in the supply duct to cycle with on and off with the system
fan.
4. Monitor- Diagnosis/Comfort Controls
Programmable thermostats, zoning and ductwork improvements may be
part of the solution.
