Ventilators will help protect your home and your Family

Protecting your Home

 

Excess Moisture Can Damage Your Home.

Breathing, showering and cooking are just a few ways that moisture is generated in your home (about one gallon per person, everyday). When that moisture is trapped in your home, the result can be “sweaty windows” and other moisture damage such as rust, mildew, mold and odor. Structural damage from excess moisture is often the easiest to spot - heavy condensation on windows, water damage on window sills and molds forming in cold corners of the home.

Ventilation Protects Your Home From Extremes in Humidity

Intermittent excessive humidity can be controlled with ample exhaust ventilation. Intermittent sources of humidity include bathing and showering, cooking and dish washing and clothes washing. These humidity producing activities are generally of short duration and can be controlled using ceiling mounted ventilation fans or a centrally ducted exhaust system. When air is exhausted from a home, an equal amount of outdoor air must replace it. Caution should be exercised with any exhaust-only approach to insure that associated negative pressure will not cause back drafting of combustion appliances and the introduction of uncontrolled outdoor air through building materials.

Homes in different parts of the country face a wide range of humidity conditions – from very dry to extremely wet. For over 25 years RenewAire has manufactured Energy Recovery Ventilators (ERVs) that moderate extremes in outdoor temperature and humidity. Since RenewAire ERVs have both an exhaust fan and a fresh air supply fan it is a pressure balanced ventilation system in one appliance. The result is ideal ventilation year-round.

Poor Ventilation May Be Harmful to Your Family’s Health

 

Indoor air pollution is the uncomfortable or unhealthful presence of high levels of pollutants. Lingering odors may simply be a daily annoyance. Formaldehyde and other Volatile Organic Compounds (VOCs), cigarette smoke, radon, household cleaners, even perfumes can threaten health. Protect your family from the health problems that are associated with:

• Carbon Dioxide (CO2) - can cause headaches, drowsiness and reduce mental acuity
• Smoke - can cause irritated eyes and respiratory problems like bronchitis and pneumonia
• High Humidity - promotes asthma, encourages fungal growth and house dust mites
• Formaldehyde - can cause headaches, sore throats, respiratory, eye and skin irritations, sinus problems, nasal congestion, hearing loss, arthritis, depression and memory impairments
• Ammonia - can cause eye, nose and respiratory tract irritation
• Radon - is an invisible, odorless gas that can seep into homes from the ground, and in time can cause cancer
• Volatile Organic Compounds - many building materials including paints, carpets and adhesives contain substances that outgas and can cause allergic reactions

 

How They Work

 

The RenewAire Core

RenewAire's heat exchange core is manufactured by Mitsubishi Electric Corporation. Developed in 1971 specifically for energy recovery ventilation, this technology has gained worldwide acceptance with literally millions of successful installations. Decades of use have demonstrated that the core operates without loss of operating efficiency, retaining its strong resistance to transfer of pollutants and to biological contamination. This durable, frost-resistant technology has provided reliable, trouble-free service in thousands of North American RenewAire installations for over 25 years.

In the RenewAire energy exchange core, the exhausted stale air and the fresh ventilation air pass through multiple air passages separated by an engineered composite resin partition plate. Sensible heat transfers from the warm to the cool air stream. Also, latent energy (water vapor) transfers from the wet to the dry air stream. The fresh incoming air is automatically pre-heated or pre-cooled depending on the season. This dramatically reduces the energy costs of ventilation. This unique moisture transfer feature of the RenewAire energy exchange core also eliminates condensate and frosting in most applications. No mechanical or electrical defrost systems are needed, which means higher heat recovery efficiencies, simpler installation and more reliable operation.

During the Heating Season

Outdoor air is warmed close to room temperature with heat that would otherwise be lost with the exhaust air. The water vapor transfer moderates extremes in humidity levels which helps prevent moisture damage or over-drying of the home. The heat and humidity transfer (sensible and latent energy) gives RenewAire a big advantage over other air-to-air exchangers typically recovering 30% more energy in winter.

During the Air Conditioning Season

When you need to cool for comfort? Do you hate the stuffy, musty air quality in your home? RenewAire ERVs provide necessary fresh air while pre-cooling and pre-dehumidifying this air with energy that would otherwise be lost with the exhaust air. With summertime humidity control (latent energy) being the largest portion of air conditioning cost, RenewAire’s humidity transfer is critical. In fact RenewAire is typically three times more energy efficient than products that transfer only heat.
