Abstract:
1. A heat recovery arrangement comprising: a building interior; a bathroom; an area of exhaust; a housing including a bathroom exhaust inlet operably connected to the bathroom, an exhaust outlet operably connected to the area of exhaust, a bathroom exhaust airflow path through the housing from the bathroom exhaust inlet to the exhaust outlet, a return air inlet operably connected to the building interior, a return airflow path through the housing from the return air inlet to the exhaust outlet, an outside air inlet, a supply air outlet operably connected to the building interior, and an outside air path through the housing from the outside air inlet to the supply air outlet; and a heat recovery device transferring heat between the bathroom exhaust airflow path, the return airflow path and the outside airflow path, where the heat recovery device extracts heat from the bathroom exhaust airflow path and from the return airflow path and transfers heat to the outside airflow path and wherein the heat recovery device includes a rotating energy recovery wheel arrangement such that the device sequentially extracts heat from the bathroom exhaust airflow path and from the return airflow path.
