Mitsubishi Lossnary Energy Recovery Ventilators




Lossnay energy recovery ventilators provide outdoor air solutions for indoor environmental quality.

  • Maintain an adequate supply of ventilation air while reducing energy costs.
  • Recover up to 70 percent of sensible and latent energy from conditioned air as it is exhausted.
  • Reduce extremes in humidity that can encourage mold growth.
  • Remove dangerous gases, bacteria, and other airborne impurities from conditioned air.

Mitsubishi Electric’s Lossnay® energy recovery ventilators offer:

  • Unprecedented energy transfer in a fixedplate component with no moving parts.
  • Reasonable paybacks and reduced peak demand.
  • Superior part-load performance, reducing latent load even at mild outdoor temperatures.
  • No wheels to stop turning so outside air is always preconditioned and available.
Improved sound attenuation makes Lossnay® units quiet enough for places where silence is a must, such as meeting rooms and libraries. A free-cooling function is standard to help reduce costs and boost efficiency. The integrated, bypass damper design makes installation and system management quick and efficient.

Commercial Department

The Commercial Department of Howell's Heating & Air Conditioning consists of three sales engineers, one field supervisor, one contract administrator, and eleven field crews. We have been doing a wide range of commercial design build, plan & spec work in central Virginia since 1970. New and renovation projects include restaurant work, retail stores, grocery stores, schools, motels, and hotels. The Commercial Department is fully computerized. Howell's sales engineers use computers to design system layouts and our on-site fabrication shop uses computers to produce metal and fiberglass duct work and fittings. Our service staff can provide preventative and full service maintenance for the life of the building. Our objective is not to simply get jobs, but to develop customers. Many of our clients have been repeat customers over the years and that is something we have learned not to take lightly.

Nitrogen Dioxide - Reference Guide to Major Indoor Air Quality Pollutants in the Home

In this series, we'll detail the sources, health effects, levels in the home, and steps to reduce exposure to the 11 major indoor air quality pollutants in the home.

Nitrogen Dioxide

Sources
Kerosene heaters, unvented gas stoves and heaters. Environmental tobacco smoke.

Health Effects
Eye, nose, and throat irritation. May cause impaired lung function and increased respiratory infections in young children.

Levels in Homes
Average level in homes without combustion appliances is about half that of outdoors. In homes with gas stoves, kerosene heaters, or unvented gas space heaters, indoor levels often exceed outdoor levels.

Steps to Reduce Exposure
  • Keep gas appliances properly adjusted.
  • Consider purchasing a vented space heater when replacing an unvented one.
  • Use proper fuel in kerosene space heaters.
  • Install and use an exhaust fan vented to outdoors over gas stoves.
  • Open flues when fireplaces are in use.
  • Choose properly sized woodstoves that are certified to meet EPA emission standards. Make certain that doors on all woodstoves fit tightly.
  • Have a trained professional inspect, clean, and tune-up central heating system (furnaces, flues, and chimneys) annually. Repair any leaks promptly.
  • Do not idle the car inside garage.

Carbon Monoxide - Reference Guide to Major Indoor Air Quality Pollutants in the Home

In this series, we'll detail the sources, health effects, levels in the home, and steps to reduce exposure to the 11 major indoor air quality pollutants in the home.

Carbon Monoxide

Sources
Unvented kerosene and gas space heaters; leaking chimneys and furnaces; back-drafting from furnaces, gas water heaters, woodstoves, and fireplaces; gas stoves. Automobile exhaust from attached garages. Environmental Tobacco Smoke.

Health Effects
At low concentrations, fatigue in healthy people and chest pain in people with heart disease. At higher concentrations, impaired vision and coordination; headaches; dizziness; confusion; nausea. Can cause flu-like symptoms that clear up after leaving home. Fatal at very high concentrations.

Levels in Homes
Average levels in homes without gas stoves vary from 0.5 to 5 parts per million (ppm). Levels near properly adjusted gas stoves are often 5 to 15 ppm and those near poorly adjusted stoves may be 30 ppm or higher.

Steps to Reduce Exposure:
  • Keep gas appliances properly adjusted.
  • Consider purchasing a vented space heater when replacing an unvented one.
  • Use proper fuel in kerosene space heaters.
  • Install and use an exhaust fan vented to outdoors over gas stoves.
  • Open flues when fireplaces are in use.
  • Choose properly sized woodstoves that are certified to meet EPA emission standards. Make certain that doors on all woodstoves fit tightly.
  • Have a trained professional inspect, clean, and tune-up central heating system (furnaces, flues, and chimneys) annually. Repair any leaks promptly.
  • Do not idle the car inside garage.

Product Feature: Condensate Pump

Remove the nuisance of ugly hoses or pipes running across the floor.

Condensation or wastewater is a byproduct of high efficiency furnaces, air conditioning evaporator coils, and flow- through humidifiers. A condensate pump is used to transfer this wastewater to a proper drain.
