It is always important to assess how the operation of any Energy Recovery Ventilator may interact with vented combustion equipment (ie. Gas Furnaces, Oil Furnaces, Wood Stoves, etc.)

NEVER install an Energy Recovery Ventilator in a situation where its normal operation, lack of operation or partial failure may result in the backdrafting or improper functioning of vented combustion equipment!!!

INTRODUCTION

The LIFEBREATH Enthalpic Core Energy Recovery Ventilator (ERV) is designed for warm, humid regions and it uses the vapour transmission technology to transfer sensible and latent heat to the cooler, drier air stream. During the cooling season, humidity drawn in from the outside is transferred through the core to the exhaust air stream, helping lower the load on the air conditioner. It is recommended for regions where the temperature does not drop below 25˚F (-4˚C).

WARRANTY

All LIFEBREATH Energy Recovery Ventilators carry a five year warranty on the Energy Recovery Core, Model 200ERV has a 5 year warranty on replacement parts and Model 500, 700, and 1200 ERV has a 2 year warranty on replacement parts.

ERV Questions & Answers

What is the difference between an HRV and an ERV?

The core in an HRV (Heat Recovery Ventilator) transfers heat from one air stream to the other. This is called

sensible heat

Ventilator) is usually used to describe a unit with an enthalpic core that transfers moisture as well as heat from one air stream to the other. This (moisture transfer) is called

. The term ERV (Energy Recovery

latent heat

Enthalpic - what does it mean?

Enthalpy is the term used to describe the energy content of air. This energy is a combination of the sensible and latent heat. Therefore, a core which transfers energy is called an enthalpic core.

Is an ERV better than an HRV?

NOT NECESSARILY!! In cold climates such as most of North America, an HRV works better than an ERV. This is because the air inside the home during the winter months will be more humid than the outside air. An ERV would transfer the latent heat (humidity) from the exhaust air back into the incoming airstream. This will aggravate moisture problems in the home and encourage the growth of mold and mildew. If the air in the home is too dry for comfort, an ERV will not help. A humidifier should be used to increase the humidity to a comfortable level.

Where do you use an ERV instead of an HRV?

An ERV is recommended for warm, humid areas with heavy air conditioning use. As there is no defrost in an ERV it is not recommended for areas where the temper-

ature drops below -4

˚C (25˚F)

Why transfer moisture in the summer (cooling season)?

The enthalpic core will allow moisture to be transferred from a humid air flow to a dry air flow. This property is useful in the cooling season if an air conditioning system is used to lower the indoor humidity. You will then have dry, cool air in the exhaust of the ERV, and warm humid air in the supply stream. With these conditions, the ERV will be able to transfer the moisture and heat of the supply air to the exhaust air. In this way, the ERV will supply to the home air which is cooler and drier than outside. Remember that an ERV is not a dehumidifier, and on its own will not take moisture out of the air.

damp situation. In fact, about 2/3 of the energy used by the air conditioner system is to remove moisture. Therefore, when ventilating in the summer, less moisture brought into the home means less work for the air conditioner, and energy savings for you.

During the winter, an ERV recovers some humidity from the exhaust air, reducing the need for humidification, if the required ventilation rate would make the home too dry.

What's the difference between this type of core and a rotary type?

Here's a list of characteristics of the fixed plate core.

1. No rotating parts, so maintenance is easy and the unit lasts a long time.

2. It is very flexible in terms of installation.

3. The core can easily be changed.

4. Because the supply and exhaust air streams are

completely separate, there is very little cross leakage of any dust or germs.

Can the core become clogged with dust?

Because the surface of the core is a turbulent flow area, dust sticks to it easily; however, because the inside of the element is a laminar flow area, virtually no dust sticks to it.

What is the maintenance?

About once a year you should use a vacuum cleaner to remove the dust from the core's surface. DO NOT WASH WITH WATER!!

Is an air filter needed?

To prevent clogging of the core, an air filter should always be installed on the supply and exhaust sides of the core.

How much ventilation do I need?

During seasons when your windows and doors are closed, the ERV should operate continuously when the dwelling is occupied, and either continuously or intermittently when not occupied.

For most installations the ERV will normally be set to operate continuously on low speed with the option of going to high speed as the need arises. For example; if you are entertaining and there is a large number of people present (some may be smoking), the unit should be switched to high speed.

So why use an ERV?

A properly operating air conditioner will not only lower the temperature in your house, but will also lower the humidity level. This prevents an uncomfortable cold and

Your ERV may be equipped with automatic or manual switches, but all ERVs will have a manual speed control override.

The following table is used to outline total dollar ventilation costs for Heat Recovery Ventilators (HRV's) and Energy Recovery Ventilators (ERV's) for various geographic regions in the United States and Canada. Costs are for balanced systems using values based on electricity at $0.086 per kWh and fossil fuel at $0.72 per therm (100, 000 BTU). It was assumed that electric heat was 100% efficient and fossil fuel heat was 80% efficient. Cooling equipment had a SEER of 12.

Ventilation energy costs would include both fan energy use and the energy required to condition the air displaced by the ventilation system.

Straight ventilation costs are also included to show the benefit of recovery.
