Quick Tips
Particle counts Particle counts vary according to a number of factors such as
location, time of year, and occupants. When taking particle counts, always
establish an outside baseline reading to compare indoor particle levels
against. Ideally, indoor particle levels will be less then outdoor levels.
Filter bypass When testing for filter bypass, take particle counts before and
after sealing the edges of the filter with duct tape. This will provide an
indication of how much particulate matter is bypassing the filter due to poor
fitment or compromised sealing surfaces.

Growing your business through indoor air quality particulate profiling
You’ve probably heard mold referred to as the “new asbestos” for HVAC/R.
Concern about mold and its health effects is driving consumers to have their
indoor air quality (IAQ) situation assessed and, if necessary, repaired.
If you’re the contractor they call, keep in mind that mold isn’t the only
issue to consider when assessing the IAQ of a commercial building or
residence. Many different kinds of particulates in a work or living
environment can cause Sick Building Syndrome and aggravate allergy and
respiratory conditions. Read a detailed application note on www.fluke.com/iaq

Quick Tips
Frequent Calibration is Key Frequent calibration of gas sensors is key to
maintaining the accuracy and performance of the device. Both CO2 and CO
sensors can exhibit tendencies to drift over time due to environmental factors
such as temperature, humidity, and pressure.
Fluke recommends monthly calibration of the CO sensor, and an annual
calibration for CO2 for optimum performance.

Making the numbers add up: Understanding specifications and performance of
indoor air quality test instruments
Air quality test instruments must deliver accurate and verifiable performance,
both to ensure precise and reliable air quality diagnosis, and to provide
credible answers if results or procedures are challenged. The air quality
professional’s reputation depends on the quality and performance of the test
tools in use, as well as on their understanding of instrument specifications,
technologies, applications and maintenance.

Air velocity is a key parameter in evaluating airflow system performance. As
part of basic testing, adjusting and balancing of HVAC air distribution
systems, most HVAC technicians now use an anemometer to measure air velocity
at grilles-registers-diffusers, within a duct, or in open spaces.
Anemometers are typically very accurate tools, especially at low velocities,
but they must compensate for air temperature, absolute pressure, and ambient
absolute pressure. The Fluke 975 AirMeter tool has an accessory velocity probe
that uses a thermal anemometer to measure air velocity. A temperature sensor
in the probe tip compensates for air temperature, a sensor in the meter reads
absolute pressure, and ambient absolute pressure is determined upon meter
initialization. For users who prefer to calculate their own compensation
factors, the meter will also display air velocity or volume at standard
conditions.
This application note describes how to take accurate air volume measurements
within a duct, air measurements at grilles-registers-diffusers, and other
locations.
tion systems, technicians measure air velocity at grilles/ registers/diffusers within a duct or in open space.
Air volumes within a duct
The ultimate goal of any duct system is to move the required air volume, while
keeping all other factors within acceptable limits, and to deliver it in
quantities and patterns that serve the intended purpose: heating, cooling,
ventilating, exhausting, mixing, humidifying, dehumidifying, or otherwise
conditioning the air within a space. Velocity within a duct is determined not
only by application, but also by how the duct is designed. Key design factors
include: The level of available static pressure that can be overcome by the
fan due to friction losses and pressure drops of devices within the air
stream; the cost of duct work; the space available for duct work; and
acceptable noise levels.
To determine the air volume delivered to all downstream terminal devices, technicians use a duct traverse. Duct traverses can determine air volume in any duct by multiplying average velocity readings by the inside area of the duct. Traverses in main ducts measure total system air volume, which is critical to HVAC system performance, efficiency, and even life expectancy. The difference in air volumes between the main supply duct traverse and the main return duct traverse results in outdoor air volume. A traverse in run-outs is the most accurate way to determine the air volume delivered by the terminal device (grille-register-diffuser). A traverse in exhaust ducts reveals exhaust air volume.

Quick Tips
How HVAC airflow impacts operating costs
Dirty coils, fans, and filters will increase static pressure by reducing
airflow, causing HVAC equipment to work harder to meet occupant loads and
increasing energy costs. With HVAC energy costs often comprising over 50 % of
the total energy bill, tighter monitoring and control of HVAC airflow can have
a direct impact on the bottom line.
· In a study1 on coil clean-
ing and energy savings in a New York City high rise, pressure monitoring and
visual inspection led to restoration of the coils and components. The
restoration resulted in a 14 % decrease in pressure drop across the coils, a
25 % increase in the coil’s thermal efficiency, and energy savings of up to
$40,000 in the first year.
· EPA studies2 show that a 15
cfm airflow differential can impact annual HVAC energy costs by up to 8 %
depending upon the HVAC system and variations in climate.

How many people are unintentionally poisoned by CO?
Every year, over 200 people in the United States die from CO produced by fuel-
burning appliances (furnaces, ranges, water heaters, room heaters). Others die
from CO produced while burning charcoal inside a home, garage, vehicle or
tent. Still others die from CO produced by cars left running in attached
garages. Several thousand people go to hospital emergency rooms for treatment
for CO poisoning.
What is the permissible exposure to CO?
The current Occupational Safety and Health Administration (OSHA) permissible
exposure limit (PEL) for carbon monoxide is 50 ppm over an 8-hour time period.

Quick Tips
Duct temperatures
Use the Fluke 971 and an infrared thermometer to monitor duct temperatures at
the register. Easily calculate dewpoint with the Fluke 971, then compare it to
register temperatures to see if they fall below the dewpoint. Use an infrared
thermometer in this application as a general indicator only. Many factors come
into play when taking IR measurments, such as emissivity and spot-to-distance
ratio. Lower temperatures can lead to condensation forming on ductwork. If
uninsulated, moisture can fall onto ceiling materials and cause potential mold
issues and water damage.

Quick Tips
Measuring superheat and subcooling
To measure superheat:
- Measure suction pressure with a pressure module and your digital multimeter (DMM). Convert pressure to temperature using your PT chart.
- Measure the pipe temperature at the outlet of the evaporator with a pipe clamp and your temperature meter.
- Subtract the difference in temperatures to obtain superheat.
To measure subcooling: - Measure liquid line pressure (or discharge pressure if there is no liquid line access valve) with a pressure module and your DMM. Convert the pressure to temperature using your PT chart.
- Measure the pipe temperature at the outlet of the condenser with a pipe clamp and your temperature meter.
- Subtract the difference in temperatures to obtain subcooling.

Why true-rms matters for HVAC technicians
Non-linear loads need a true-rms test tool for accurate readings For today’s
HVAC technician, troubleshooting electrical problems is becoming more
difficult without the use of true-rms test tools. This is due in part to the
proliferation of new solid state adjustable speed motor drives and heating
controls containing power semiconductors or rectifiers. These loads are
referred to as “non-linear.” Non-linear loads draw current in short pulses
rather than the smooth sine wave drawn by a linear load such as an induction
motor. The current wave shape can have a drastic effect on a test tool
reading. Read a detailed application note on www.fluke.com/iaq

V = A x
Where: V = Volts A = Current in Amps = Resistance in Ohms
Ohm’s Law explains the relationship between voltage, current and resistance.
Put your finger over the value you want to find. Multiply the remaining values
if sideby-side; divide if one is over the other. But it really is much easier
just to use your DMM.

A detailed list of heating, air conditioning, and HVAC terms
Glossary
Absolute humidity: The mass of water vapor per unit volume of air.
Absolute pressure: Pressure above a perfect vacuum. Absolute pressure is the
sum of gage pressure plus atmospheric pressure.
Air exchange rate: Used in two ways: 1. the number of times the outdoor air
replaces the volume of air in a building per unit time, typically expressed as
air changes per hour; 2. the number of times that the ventilation system
replaces the air within a room or area within the building.
Air flow: The movement of air from one location to another, commonly measured
in cubic feet per minute (CFM).
Air velocity: The distance traveled per unit of time, commonly measured in
feet per minute (FPM).
Air handling unit (AHU): Refers to equipment that includes a blower or fan,
heating and/or cooling coils, and related equipment such as controls,
condensate drain pans, and air filters. Does not include ductwork, registers
or grilles, or boilers and chillers.
Allergen: A substance capable of causing an allergic reaction because of an
individual’s sensitivity to that substance.
Ambient air: Unconditioned atmospheric air.
Atmospheric pressure: Standard atmosphere is the pressure equivalent of 14.696
psi or 29.921 in. Hg at sea level. Measured with a barometer, it is an
indication of the “weight” of the air.
Boiler: A pressure vessel that safely and efficiently transfers heat to water.
Carbon monoxide: A clear, odorless gas made when carbon or other fuel is
burned during the combustion process. The gas is poisonous, with exposure
resulting in symptoms such as headaches, nausea, or even death.
Ceiling plenum: Space below the flooring and above the suspended ceiling that
accommodates the mechanical and electrical equipment and that is used as part
of the air distribution system. The space is kept under negative pressure.
Central air handling unit (Central AHU): This is the same as an Air Handling
Unit, but serves more than one area.
Chiller: Hydronic air conditioning system which cools water, which cools air.
Compressor: Mechanical device that compresses refrigerant or other fluid.
Condensate: Liquid formed when a vapor has cooled below its dewpoint.
Condenser: Heat exchanger that removes heat from high-pressure refrigerant
vapor.
Conditioned air: Air that has been heated, cooled, humidified, or dehumidified
to maintain an interior space within the “comfort zone.” (Sometimes referred
to as “tempered” air.)
Constant air volume systems: Air handling system that provides a constant air
flow while varying the temperature to meet heating, and cooling needs.
Cooling coil: Typically copper or aluminum tubing arranged to transfer the
heat from air to a refrigerant.
BTU: British Thermal Unit. A measure of the heat given off when fuel is combusted. One BTU is equal to the heat necessary to raise one pound of water 1 °F.
Dampers: Controls that vary airflow through an air outlet, inlet, or duct. A damper position may be immovable, manually adjustable or part of an automated control system.
Building envelope: Elements of the building, including all external building materials, windows, and walls, that enclose the internal space.
Demand controlled ventilation: Any system used to vary air intake rates based upon the loads placed upon the system, given a predefined space.
Building-related illness (BRI): Diagnosable
Dewpoint temperature (dp): Temperature below
illness whose symptoms can be identified and
which moisture in the air begins to condense.
26
whose cause can be directly attributed to airborne
building pollutants (e.g., Legionnaire’s disease,
Differential pressure: The difference in static
hypersensitivity pneumonitis).
pressure measured between two locations.
Capacity: The output of a heating or cooling system for a given amount of space. For heating, this is usually expressed in BTU’s. For cooling, it is usually expressed in tons.
Diffusers: Components of the ventilation system that distribute and diffuse air to promote air circulation in the occupied space. Diffusers supply air, and grilles return air.
Carbon dioxide: (CO2), a clear, odorless gas found in nature (around 380 ppm), most commonly associated with respired air. The gas is largely considered non- poisonous, but can result in suffocation in sufficient quantities.
Draft: Air movement resulting in a local cooling effect on the body. The intensity of the draft is dependent upon a variety of factors which include air velocity, temperature, occupant activity, and occupant clothing.
Drain trap: A dip in the drain pipe of sinks, toilets, floor drains, etc., which is designed to stay filled with water, thereby preventing sewer gases from escaping into the room.
Dry bulb temperature: Measurement of sensible heat.
Economizer: A mechanical device that makes system adjustments in response to
changing conditions in order to maximize energy efficiency. An economizer
typically contains a thermostat control that opens the dampers when outside
air temperatures are lower than indoors, providing “free cooling”. Many
economizers will incorporate humidity sensors to ensure outside air is both
cool and dry enough to allow indoors, unconditioned.
Heat exchanger: Material that transfers heat from one substance to another
without allowing the substances to mix.
Heat pump: Mechanical compression refrigeration system that contains devices
and controls that reverse the flow of refrigerant. Reversing the flow of
refrigerant switches the relative position of the evaporator and condenser.
Heat: Form of energy identified by temperature difference or a change of
state.
Emissivity: The efficiency with which the surface material of a certain object
emits energy. Emissivity is an important consideration in using infrared to
measure temperatures on reflective surfaces.
Enthalpy: (h) Total heat contained in a substance, which is the sum of
sensible heat and latent heat.
Evaporator coil: Cools and dehumidifies the air by converting liquid
refrigerant into a gas, which absorbs the heat from the air.
Exfiltration: The controlled or uncontrolled movement of air out of a
building, through cracks, and other openings.
Exhaust air: Air that is removed from a space, and not recirculated into the
system.
Exhaust ventilation: Mechanical removal of air from a portion of a building
(e.g., piece of equipment, room, or general area).
Fan coil: A component of a heat pump system, used to provide additional heat
when the heat pump does not provide adequate heating.
HEPA: High efficiency particulate arrestance (filters).
Hydronic heating system: Heating system that uses water, steam, or other fluid
to carry heat from the point of generation to the point of use.
Indoor air pollutant: Particles and dust, fibers, mists, bioaerosols, and
gases or vapors.
Infiltration air: Air that flows into a building when outer doors are open or
when air leaks in through cracks around doors, windows, or other openings.
Laminar air flow: Streamlined airflow in which the entire mass of air within a
designated space moves with uniform velocity in one direction along parallel
flow lines with minimal mixing.
Latent heat: Heat identified by a change of state and no temperature change.
Load: The amount of heat imposed on a refrigerant system, or the required rate
of heat removal in order to maintain a constant temperature in a building.
Typically expressed as a unit of heat per unit of time (i.e. BTU/hr).
Filter efficiency: The ratio of particles trapped by filter media compared to the total number of par-

A detailed list of heating, air conditioning, and HVAC terms
Glossary
Particulate: Small liquid or solid particles found in air or emissions.
Airborne particles can be generated as a result of a mechanical break up of
solid matter (“coarse particles”) or through chemical reactions or condensing
gases (“fine particles”). Typically measured in micrometers, particle sizes
vary greatly in size and therefore behavior. Particles greater than 1 micron
tend to settle out of the atmosphere but remain suspended given sufficient air
currents. Particles ranging from 0.1 to 1 micron tend to stay airborne with
the slightest air movement, and smaller than 0.1 will typically remain
suspended indefinitely.
PELs: Permissible Exposure Limits (standards set by the Occupational, Safety
and Health Administration, OSHA).
Pickup: Additional heat needed to warm the water in a hydronic heating system
after a period of offtime such as overnight.
Plenum: Air compartment connected to a duct or ducts.
Pollutant pathways: Avenues for distribution of pollutants in a building. HVAC
systems are the primary pathways in most buildings; however all building
components interact to affect how air movement distributes pollutants.
Positive pressure: Condition that exists when more air is supplied to a space
than is exhausted, so the air pressure within that space is greater than that
in surrounding areas. Under this condition, if an opening exists, air will
flow from the positively pressurized space into surrounding areas.
Pressure drop: Decrease in water pressure caused by friction between water and
the inside surface of a pipe as the water moves through the pipe.
RELs: Recommended Exposure Limits (recommendations made by the National
Institute for Occupational Safety and Health (NIOSH)).
Respirable particles: Airborne particles that are of a size that can penetrate
into the lower respiratory tract. Such particles are often labeled “PM10”
particles, which include particulate matter with a diameter of 10 micrometers
or less.
Return air: The air that is removed from a space and recirculated or exhausted
to the outside.
RMS: “root mean square.” It comes from a mathematical formula that calculates
the “effective” value (or heating value) of any ac wave shape. “True-rms”
calculates the heating value based upon the rms formula, providing an accurate
value regardless of the wave shape.
Saturated air: Air which cannot hold more moisture, where the addition of
moisture will result in condensation.
SEER: The Seasonal Energy Efficiency Ratio is a measure of the cooling
efficiency of an air conditioner or heat pump. The ratio is defined as the
total output provided by the unit over a typical usage period divided by the
total energy input over the same period of time. The higher the SEER number,
the more efficient the system is at converting electricity into cooling power.
Sensible heat: Heat that does not involve a change of state measured with a
thermometer or sensed by a person.
Setpoint temperature: 1. In a forced-air heating system, the temperature at
which the switch in a thermostat opens and closes. 2. In a hydronic heating
system, the temperature at which the boiler water is maintained.
Static pressure: In flowing air, the total pressure minus velocity pressure. The portion of the pressure that pushes equally in all directions.
Sick building syndrome (SBS): Term that refers to a set of symptoms that affect some number of building occupants during the time they spend in the building and diminish or go away during peri-

air inside a building that results from heated air rising and escaping through openings in the building super structure, thus causing an indoor pressure level lower than that in the soil gas
beneath or surrounding the building foundation.
Static pressure: Pressure exerted in all directions by a fluid or gas at rest.
For fluids in motion, measured perpendicular to the direction of flow.
Steam trap: Steam boiler accessory that removes air and condensate from steam
lines, and heating units.
Subcooling: Process of cooling of a substance such as a refrigerant to a
temperature that is lower than the saturated temperature of the substance at a
particular pressure.
Superheat: Sensible heat that is added to a substance after the substance has
turned to vapor.
Supply air: A conditioned mixture of return air, and outside air delivered to
a space.
Time-weighted average concentration (TWA): Refers to concentrations of
airborne materials which have been weighted for a certain time duration,
usually eight hours.
(TLV) threshold limit value: A time-weighted average concentration under which
most people can work consistently for eight hours a day, day after day,
without suffering harmful effects. The American Conference of Governmental
Industrial Hygienists publishes a table of these values and accompanying
precautions annually.
Ton: A unit of measure for cooling capacity. One ton=12,000 BTUs per hour.
Unit ventilator: A fan-coil unit package device for applications in which the
use of outdoor- and return-air mixing is intended to satisfy tempering
requirements, and ventilation needs.
Unitary system: Air conditioning system that has all components enclosed in
one cabinet.
Variable air volume system (VAV): Air distribution system in which the air
flow rate in the building spaces is varied by mixing dampers, but the
temperature of the supply air remains constant.
Ventilation rate: The rate at which indoor air enters and leaves a building.
Expressed in one of two ways: the number of changes of outdoor air per unit of
time (air changes per hour, or “ach”) or the rate at which a volume of outdoor
air enters per unit of time (cubic feet per minute, or “cfm”).
Volatile organic compounds (VOCs): Compounds that vaporize (become a gas) at
room temperature. Common sources which may emit VOCs into indoor air include
housekeeping and maintenance products, and building and furnishing materials.
In sufficient quantities, VOCs can cause eye, nose, and throat irritations,
headaches, dizziness, visual disorders, memory impairment; some are known to
cause cancer in animals; some are suspected of causing, or are known to cause,
cancer in humans.
Wet-bulb temperature: The lowest air temperature that can be reached through
evaporation at a specific air saturation point. Wet bulb and dry bulb
temperatures will be identical at 100 % air saturation.
Zone: The occupied space or group of spaces within a building which has its
heating or cooling controlled by a single thermostat.
