Combined HRV and mini-split ?
Are there commercially available units which combine heat-recovery ventilation with an air-to-air heat pump?
I'm imagining something that could transfer heat from the exhaust duct to the supply duct of the HRV as needed during the heating season and vice-versa in the cooling season. Heat transfer within the HRV would be wholly conventional and the additional heating/cooling would be introduced in the duct supplying air from the HRV to the house.
