Indoor It s been a problem for tens of thousands of years. Maybe it s time to fix it. From the Padahlin caves in Myanmar to New Mexico s Tsankawi Mesa pueblos, ancient human dwellings are stained with soot from cooking fires. Paleolithic people had problems with air quality indoors before they even had doors. Fast forward to the twenty-first century. We ve quit barbecuing cave bear in the living room, but indoor air quality (IAQ) is still an issue. Problems appeared to increase after the 1970s energy crisis, when architects and owners redesigned HVAC systems, adjusted operations and sealed buildings more effectively in an effort to conserve energy. The term sick building syndrome (SBS) describes situations when building occupants experience health and comfort effects that appear to be linked to time spent in a building, but no specific illness or cause can be found. Professionals use the term building related illness (BRI) when symptoms of diagnosable illness can be attributed directly to airborne building contaminants. The effects Health effects from indoor air pollutants may be experienced soon after exposure or, possibly, years later. Immediate effects include irritation of the eyes, nose, and throat, headaches, dizziness, and fatigue. Such immediate effects are usually short-term and treatable. Sometimes the treatment is simply eliminating the person s exposure to the source of the pollution, if it can be identified. Certain immediate effects are similar to those from colds or other viral diseases, so it s often difficult to determine if the symptoms are a result of exposure to indoor air pollution. For this reason, it s important to pay attention to the time and place symptoms occur. If the symptoms fade or go away when a person is away from home, for example, an effort should be made to identify home indoor air sources that may be possible causes. Some effects may be made worse by an inadequate supply of outdoor air or from the heating, cooling, or humidity conditions prevalent in the home. What do we mean by indoor air quality? Humidity and temperature are important comfort factors, and failure to manage them can create other problems allowing the growth of mold, or turning chillers into biology experiments. Common indoor air pollutants include tobacco smoke; biological agents like animal dander, bacteria and mold; airborne particulates; volatile organic compounds like glue, solvents, cleaning agents; carbon dioxide and carbon monoxide; and pesticides. Many of these materials are found in minute amounts in most indoor environments. When concentrations or combinations of pollutants rise excessively, however, IAQ deteriorates. IAQ problems can result from a host of factors. What Causes Indoor Air Problems? Indoor pollution sources that release gases or particles into the air are the primary cause of indoor air quality problems in homes. Inadequate ventilation can increase indoor pollutant levels by not bringing in enough outdoor air to dilute emissions from indoor sources and by not carrying indoor air pollutants out of the home. High temperature and humidity levels can also increase concentrations of some pollutants. Pollutant Sources Indoor Air Quality What you will learn in this module: What are the origins of indoor air quality problems? How can one evaluate an indoor environment? What steps can be taken to improve indoor air quality? Page Fluke Corporation FACT
There are many sources of indoor air pollution in any home. These include combustion sources such as oil, gas, kerosene, coal, wood, and tobacco products; building materials and furnishings as diverse as deteriorated, asbestos-containing insulation, wet or damp carpet, and cabinetry or furniture made of certain pressed wood products; products for household cleaning and maintenance, personal care, or hobbies; central heating and cooling systems and humidification devices; and outdoor sources such as radon, pesticides, and outdoor air pollution. The relative importance of any single source depends on how much of a given pollutant it emits and how hazardous those emissions are. In some cases, factors such as how old the source is and whether it is properly maintained are significant. For example, an improperly adjusted gas stove can emit significantly more carbon monoxide than one that is properly adjusted. Some sources, such as building materials, furnishings, and household products like air fresheners, release pollutants more or less continuously. Other sources, related to activities carried out in the home, release pollutants intermittently. These include smoking, the use of unvented or malfunctioning stoves, furnaces, or space heaters, the use of solvents in cleaning and hobby activities, the use of paint strippers in redecorating activities, and the use of cleaning products and pesticides in housekeeping. High pollutant concentrations can remain in the air for long periods after some of these activities. Amount of Ventilation If too little outdoor air enters a home, pollutants can accumulate to levels that can pose health and comfort problems. Unless they are built with special mechanical means of ventilation, homes that are designed and constructed to minimize the amount of outdoor air that can leak into and out of the home may have higher pollutant levels than other homes. However, because some weather conditions can drastically reduce the amount of outdoor air that enters a home, pollutants can build up even in homes that are normally considered leaky. How Does Outdoor Air Enter a House? EXHAUST AIR Outdoor air enters and leaves a house by: OUTDOORS OUTDOOR AIR EXHAUST DAMPER RETURN DAMPER OUTDOOR AIR DAMPER infiltration, natural ventilation, and mechanical ventilation. In a process known as infiltration, outdoor air flows into the house through openings, joints, and cracks in walls, floors, and ceilings, and around windows and doors. In natural ventilation, air moves through opened windows and doors. Air movement associated with infiltration and natural ventilation is caused by air temperature differences between indoors and outdoors and by wind. Finally, there are a number of mechanical ventilation devices, from outdoor-vented fans that intermittently remove air from a single room, such as bathrooms and kitchen, to air handling systems that use fans and duct INDOORS RESET OR ECONOMIZER STAT TEMPERATURE SENSOR AIR CONTROL DAMPER RETURN AIR MIXED AIR ROOM(S) RETURN AIR STAT HEATING COIL COOLING COIL DRAIN PAN AIR FILTER(S) CENTRAL AIR HANDLING UNIT UNIT VENTILATOR MIXED AIR STAT FREEZE STAT SUPPLY AIR BLOWER work to continuously remove indoor air and distribute filtered and conditioned outdoor air to strategic points throughout the house. The rate at which outdoor air replaces indoor air is described as the air exchange rate. When there is little infiltration, natural ventilation, or mechanical ventilation, the air exchange rate is low and pollutant levels can increase. Keys to IAQ: design, operation and maintenance of HVAC systems Poor design of buildings and HVAC systems is one cause. An air intake located above a loading dock, for instance, could draw in vehicle exhaust and distribute carbon monoxide, oxides of nitrogen and diesel soot to every Indoor Air Quality Page Fluke Corporation FACT
cubicle. Systems without sufficient fresh air exchange can allow CO 2 and volatile organic compounds to build up. The wrong construction materials can emit excessive chemicals from glue and paint. Another big factor is system operation. Air pressure, temperature, humidity and operating cycles must all be properly adjusted to balance operating efficiency with the comfort of building occupants. Leaving systems off until occupants arrive in the morning might save money, for instance, but allow pollutants to build up in the air. Better to start systems early and condition the air before people show up. Leaving doors or windows open between office space and a shop floor could virtually guarantee IAQ problems. The third big IAQ determinant is system maintenance. Even the best building and HVAC design won t deliver the results it should if electrical systems or vents fail, filters aren t frequently changed or correctly installed, fan and compressor motors malfunction or controls fail to perform. Evaluating relative humidity: Key factors and measurements Understanding the relationship between dry bulb temperature, wet bulb temperature, relative humidity, and dew point temperature is essential in all facets of air conditioning. The good news, strangely enough, is that poor humidity and temperature levels are likely to cause occupant discomfort. Dry bulb temperature: Air temperature determined by an ordinary thermometer. Wet bulb temperature: Represents the cooling effect of evaporating water, the temperature air will cool to when water evaporates into unsaturated air. Relative humidity: Ratio of water vapor pressure (amount currently in the air) to the saturation vapor pressure (the amount the air can hold) at a given air temperature. Dewpoint temperature: The temperature under which water will condense out of the air. Fungus Conditions for fungal growth include spores settling on a surface, a micro-environment ensuring oxygen, optimal temperatures, nutrients, and moisture. Four of these conditions are found in nearly every environment. The most controllable variant is moisture. Relative humidity above 60% can support fungal growth on hygroscopic surfaces, ones that readily take up and retain moisture. Nearly all surfaces are, or can become, hygroscopic and include painted surfaces, gypsum dry wall, carpets, wall coverings, and masonry products. Even glass with a dirt film and dust on it can support fungal growth. Masonry products such as brick, cinder block and concrete are excellent sorbents and can absorb vast quantities of moisture and become an inviting breeding environment for molds. Condensation Conditions that allow condensation to form on surfaces are more obvious, so action can be taken immediately. When a surface temperature is at or below the dew point temperature, condensation will form. Likely places for this to occur are on basement surfaces, crawlspace surfaces, cold water pipes, on air handling equipment and duct work, and unseen within envelope walls. In cooling systems, relative humidity in supply ducts can be 95 % or higher, and evaporators and condensate pans will be wet. So, since moisture control is not feasible, control of airborne spores and food (dust and airborne particles) with good, tight fitting filtration systems in place is essential to control fungus growth.

Dirty coils, fans, and filters increase static pressure by reducing airflow, causing HVAC equipment to work harder to meet occupant loads thus 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. use, as well as on their understanding of instrument specifications, technologies, applications and maintenance. s Air velocity is a key parameter in evaluating airflow system performance. As part of basic testing, adjusting and balancing of HVAC air distribution systems, technicians measure air velocity at grilles/ registers/diffusers within a duct or in open space. What you will learn in this module: How HVAC airflow impacts operating costs In a study 1 on coil cleaning 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 studies 2 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. 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 1 Baker, Robert G.; Montgomery, Ross D. Coil Cleaning and its Resultant Energy Savings and Maintenance Enhancements.

Fluke 971 Temperature Humidity Meter Temperature and humidity are two important factors in maintaining optimal comfort levels and good indoor air quality. Quickly and conveniently take accurate humidity and temperature readings with the Fluke 971, an instrument that will prove invaluable for facility maintenance and utility technicians, HVAC-service contractors, and specialists who assess indoor air quality (IAQ). Lightweight and easy to hold, the Fluke 971 is the perfect tool for monitoring problem areas. With a rugged holster and twist-open protective sensor cover, the Fluke 971 is built to perform and made to last. Backlit dual display of humidity and temperature, measures dew point and wet bulb temperatures Quick-response capacitance sensor with twist-open protective cover Compact and lightweight at 188 g (6.6 oz) Temperature range from -20 C to 60 C (-4 F to 140 F) Relative humidity from 5% to 95% 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. Airborne particle detection Over the past several years, indoor air quality (IAQ) has been a much debated and publicized topic, especially as it concerns public health. The EPA estimates that we spend approximately 90% of our time indoors, and further studies indicate that indoor air in some commercial settings is up to five times more polluted than outdoor air. Airborne particulates come in a variety of forms ranging from animal dander, plant pollen, and airborne bacteria, to fiberglass, asbestos, and combustion particles. Motionless, human beings alone shed up to 500,000 particles (0.3μm) per minute. When active, this level can reach up to 45,000,000 particles per minute. Humidity and temperature play a significant role in the generation rate of these pollutants. To properly identify and troubleshoot IAQ problems, the technician needs a tool that not only reads particle concentrations, but also provides insight into the environment that causes pollutants to grow. Why particle counts matter Different locations have varying levels of acceptable particulate concentrations, driven primarily by health and comfort concerns (i.e. homes, offices, paint booths) or contamination (i.e. hospitals, food and beverage plants, cleanrooms). Excessive levels can result in medical conditions such as Sick Building Syndrome, lower productivity, contaminated product, or all of the above. Maintaining acceptable air quality levels may not only lower the costs associated with downtime, but also reduce or remove costs associated with expensive fixes in the future. The first step in establishing an IAQ maintenance program is to determine if a problem currently exists. Fluke 983 Particle Counter This tool is a portable solution for determining airborne particle concentrations. Use the Fluke 983 to immediately respond to occupant complaints, or as part of a comprehensive preventive maintenance program. Page Fluke Corporation FACT

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 carbon monoxide (CO)? Carbon monoxide (CO) is a colorless, odorless, poisonous gas with potentially serious health consequences given adequate exposure. CO levels Exposure symptoms 70 to 100 ppm Mild headaches Sore eyes Runny nose Mild nausea Shortness of breath 150 to 300 ppm Dizziness Headaches Drowsiness Vomiting 400 and higher ppm Unconsciousness Brain damage Death Treatment options Get victim to fresh air immediately. If you can t get victim out of the building open all windows and doors. Take victim to a hospital emergency room for a carbon monoxide blood test. CO-220 Carbon Monoxide Meter Quickly and accurately measure CO levels with this easy-to-use compact meter Featuring the newest generation of electrochemical sensors, the CO-220 responds very quickly to ambient changes in carbon monoxide concentration without the use of a pump. The CO-220 is the perfect instrument for technicians and other professionals who need to measure CO levels within spaces such as industrial environments, commercial buildings, or residential dwellings where accumulation of combustion gas is possible. Standalone CO meter that does not require a digital multimeter Bright back-light allows easy screen viewing under dim lighting conditions CO levels from 0 to 1000 ppm Page 4 Fluke Corporation FACT
Beeper triggers with increasing frequency as CO levels rise MAX hold function stores and displays the maximum CO level Automatic sensor zeroing and self-test upon startup 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.
