Residential heat recovery
Interest in residential energy conservation has grown considerably in recent years. One trend is towards better-sealed and well insulated house envelopes associated with exhaust air/ventilation heat recovery. Another, which special consideration has recently been given to, is waste water heat recycling. As a result of these trends, residential waste heat recovery has become an attractive approach to efficient energy management. In a ''tightly sealed'' house without mechanical ventilation, the risk of indoor air contamination because of fewer natural air changes is a major concern. In addition, normal activities such as laundry, cooking and showers can produce excess humidity conditions. Excess humidity inside the house envelope can cause occupant discomfort, condensation on cool walls and windows, and bacterial or fungus growth. Excess humidity leaking through the house envelope (exfiltration) and condensing inside walls and attics can cause rot and collapse of wooden structural members. An innovative solution to these undesirable effects was the development of a new generation of heat pump based devices capable of providing mechanical ventilation, controlled humidity and improved indoor air quality while recovering a large part of the exhaust air energy for space and/or water heating.
