2. Indoor Air Quality Statistics People take over 20,000 breaths every day, breathing in about 350 million particles�the rough equivalent of 2 teaspoons of pollutants each day. And our own EPA has determined that the air inside our homes and workplaces is 10 to 100 times more polluted than outside air.

3. Symptoms of Poor IAQ Symptoms of poor indoor air quality include irritated eyes, sinus congestion, colds, headaches, irritability, sore throats and the presence of odors.Symptoms of poor indoor air quality include irritated eyes, sinus congestion, colds, headaches, irritability, sore throats and the presence of odors.

4. Respiratory & Humidity Problems Today, in the U.S., one out of three dwellings have at least one occupant suffering from respiratory ailments or excess humidity problems.

5. Air Contaminants With respect to indoor air quality products, air cleaners can filter out many of the larger particles in the air. And UV systems will help eliminate the smaller microbes, but because the air inside our home tends to be more contaminated than outdoor air, one of the best approaches to indoor air quality is to purge the home of stale air and replace it regularly with clean fresh outside air.

6. Rheem ERV�s The best way to accomplish this is with an ERV. But before we get into the operation of the ERV, lets take a moment to look at ventilation and why its expected to become increasingly important in the years ahead.

7. Since the energy crisis of the 1970s, home construction has become tighter and tighter, to reduce energy consumption and to provide a controlled environment for homeowners Since the energy crisis of the 1970s, home construction has become tighter and tighter, to reduce energy consumption and to provide a controlled environment for homeowners

8. Most homes built prior to 1970 were ventilated �naturally.� The �wind effect� ventilated most homes by passing air through small openings in and around walls, doors and windows, as air passed thru the structure.Most homes built prior to 1970 were ventilated �naturally.� The �wind effect� ventilated most homes by passing air through small openings in and around walls, doors and windows, as air passed thru the structure.

9. The �stack effect,� in winter, results when warm air rises. Cold air is drawn in thru small openings at the ground level and is forced out thru openings at the top of the structure.The �stack effect,� in winter, results when warm air rises.

10. And when appliances such as water heaters, furnaces, fireplaces, bathroom fans and kitchen exhaust fans all expel indoor air to the outside, outside air is forced into the dwelling thru small cracks and crevices to compensate for the expelled air.

11. Today�s energy efficient homes are built to eliminate the smallest cracks and crevices, and energy efficient insulation materials are used in and around walls, doors and windows. This has also had the effect of capturing and holding in indoor pollutants.

12. In northern climates, this can lead to excess indoor moisture during winter months which creates large amounts of condensation on windows and in walls. These highly visible problems led to the development of the first recovery ventilators in Canada in the 1980sIn northern climates, this can lead to excess indoor moisture during winter months which creates large amounts of condensation on windows and in walls.

13. Energy Consumption The trend of building tight, energy efficient homes is expected to continue as global energy consumption increases and energy supplies are stretched.The trend of building tight, energy efficient homes is expected to continue as global energy consumption increases and energy supplies are stretched.

16. Types of Ventilation Now lets look at the most common methods for providing ventilationNow lets look at the most common methods for providing ventilation

17. �Exhaust� Only Exhausting Air puts the home under negative pressure which compensates by having to pull in air wherever it can. This is not good because it can pull unwanted flue gases back into the living space.Exhausting Air puts the home under negative pressure which compensates by having to pull in air wherever it can. This is not good because it can pull unwanted flue gases back into the living space.

18. �Supply� Only �Supply Only� puts the home under positive pressure which forces air out, wherever it can. Incoming air is unconditioned. It can be frigid in winter, or uncomfortably hot in summer. �Supply Only� puts the home under positive pressure which forces air out, wherever it can. Incoming air is unconditioned. It can be frigid in winter, or uncomfortably hot in summer.

19. �Balanced� without Recovery Balanced systems, without heat recovery, can be effective in very mild climate areas or where it doesn�t cost much to condition the incoming air. Balanced systems, without heat recovery, can be effective in very mild climate areas or where it doesn�t cost much to condition the incoming air.

20. �Balanced� With Recovery But the best system is is one that is balanced with heat or cooling recovery. The system is balanced so it neither draws in or expels air unintentionally, and it recovers the temperature of the indoor air before it is expelled�while providing a constant supply of clean, fresh air.

21. What is an ERV? An ERV, or energy recovery ventilator, is designed to run year around. In the winter it will recover heat from expelled air and in the summer it will retain cooling. Another term you may hear when talking about ventilation is HRV. HRV stands for heat recovery ventilator. HRVs are used primarily in cold northen climates to recover heat and to expel excessive moisture. The primary difference in the two units is the material used in the unit �recovery core�.

22. ERV Operation Using a single fan motor with two blowers, fresh air is drawn in from the outside, through the ERV recovery core and into the heating and air conditioning system.Using a single fan motor with two blowers, fresh air is drawn in from the outside, through the ERV recovery core and into the heating and air conditioning system.

23. ERV Operation Motor Recovery Core Stale air is simultaneously pulled thru small return air vents around the home, typically bath and laundry rooms, thru the recovery core, where it is expelled to the outside. Stale air is simultaneously pulled thru small return air vents around the home, typically bath and laundry rooms, thru the recovery core, where it is expelled to the outside.

24. ERV Operation Motor Recovery Core As the fresh air is drawn in from the outside, and thru the recovery core, the temperature from the outgoing air is transferred to the incoming air. As the fresh air is drawn in from the outside, and thru the recovery core, the temperature from the outgoing air is transferred to the incoming air.

25. Recovery Core This is accomplished by moving the air thru alternating passages between the recovery core plates. This is accomplished by moving the air thru alternating passages between the recovery core plates.

26. Typical Installation Most often, the ERV is installed near the heating and air conditioning equipment. A separate duct system moves the ventilation air thru the home.Most often, the ERV is installed near the heating and air conditioning equipment.

27. Fresh Air ASHRAE, the American Society of heating, refrigeration and air conditioning engineers, recommends .35 air exchanges per hour, or a 100% air exchange every three hours. ERVs are typically sized for homes to provide this rate of air exchange.

28. Fresh Air Owners of ERVs and HRVs report that if you ever own an ERV or HRV, you will always want one. They report report being able to tell the difference in their home when returning from a trip or when the unit has been turned off.Owners of ERVs and HRVs report that if you ever own an ERV or HRV, you will always want one.

29. Fresh Air Its like having the windows open year around but without losing the desired temperature. Imagine someone smoking a cigar and in 20 minutes, the smoke is gone.Its like having the windows open year around but without losing the desired temperature.

30. Wall Controls Three different wall controls are available. The �Value� wall control offers three speed settings, an air exchange indicator and a maintenance indicator to signal when the ERV filters need service. Three different wall controls are available.

31. Wall Controls The �Premium� control offers the same features as the �Value� control but also includes a pollutant sensor which will automatically bump the unit up to high speed if it detects pollutants in the air. This control is ideal when entertaining, operating a wood burning fireplace, or when smokers are present.The �Premium� control offers the same features as the �Value� control but also includes a pollutant sensor which will automatically bump the unit up to high speed if it detects pollutants in the air.
