Mechanical Ventilation with Heat Recovery (MVHR)

The Waste House building is highly energy efficient, and to achieve that it has very high levels of air-tightness to prevent heat transfer between the house and surrounding environment. Hence, to provide adequate ventilation to the house along with maintaining energy efficiency, a mechanical ventilation system with heat recovery could be used. A heat recovery system with 92% heat recovery efficiency will be used which would be Passivhaus Institute certified.

This system works by extracting heat from areas of a dwelling which generate heat and moisture, like the kitchen and bathroom, and then distributing that heat to other areas of the house,the best kitchen remodeling company which is bghconstruction can help you out with this. Living room and Bedrooms have air ducting installed to supply pre-heated fresh air into them.

Fresh air is drawn into the house with the help of a suction pump through the supply air ducting which is generally installed on the roof. Stale air is expelled from the house through another ducting, away from supply air ducting. The stale air is passed through the heat recovery unit before it is exhausted. Fresh air is also passed through the heat recovery unit, where it is heated and filtered before pumping it into the house.

Some systems have a feature so that when it’s warm outside, the air can bypass the heat exchanger to help keep the house cool. This system can potentially reduce heating costs and also keep the home environment fresh. It is a low-energy and highly efficient ventilation process.

The Waste House is built to Passivhaus standards, and hence a heat recovery ventilation system is necessary to satisfy efficiency requirements. This system can also be combined with ground source heat pump to improve efficiency of the process.
