Heat Recovery Ventilation (HRV) is used for winter ventilation, during the heating season, transferring heat energy from the indoors back into home rather than escaping to outside, wasting energy. Energy Recovery Ventilation (ERV) are recommended below the sun belt of the lower U.S. whereas high humidity is rampant with much longer cooling seasons.
ERV units drive moisture out of the incoming outdoor fresh air into home. Throughout the cooling season, the system works to cool and dehumidify the incoming, outside air. This is accomplished by the system taking the rejected heat and sending it into the exhaust airstream. Minnesota on average only has 400-600 cooling hours for air conditioning. Our ERV Systems all meet ASHRAE 62.2 Ventilation Requirements. NO ventilation wall control needed. Fully Automated.
Relatively lower humidity levels as in comparison to southern U.S. higher humidity regions. In comparison to est. 8,000 heating operating hours during entire heating season in Minnesota. ASHRAE 62.2 recommends 24/7 ERV operation.
Traditional ventilation methods include opening a window or using a bathroom exhaust fan. These methods may not be enough to provide adequate ventilation in tighter, more well built homes that seal moisture within. An HRV or ERV can result in a healthier, more efficient and comfortable indoor home environment.
AIR EXCHANGERS drive stale, moist polluted air to outdoors and refresh your home with clean outside air, without mixing air streams, while at the same time conditioning the air in your home. The process efficiently raises or lowers the temperature of the incoming air, depending on the season, to more closely match the temperature of the air circulating throughout your home. Annual maintenance is a requirement to keep your air exchanger clean and in top-performing condition.
Whole House Air Exchangers remove excess moisture from the re-circulated air for lower humidity levels, which helps you stay comfortable at higher temperatures in the summer and lower temperatures in the winter. Properly maintained humidity levels in your home will also maximize energy efficiency and reduce utility costs.
A well balanced and properly designed air exchanger system will assist the air conditioning system dehumidification process and remove adequate moisture from home during cooling season. Xcel Energy reported for many years that
over 50% of brand New Air Conditioning Units were not installed properly by many contractors therefore reducing
overall efficiency and performance factors.
