Optimal combination of an air-to-air thermoelectric heat pump with a heat recovery system to HVAC a passive house dwelling

The main objective of this research is to propose a HVAC system for an 80–100 m2 passive house dwelling based on a thermoelectric air-to-air heat pump combined with a heat recovery unit. The computational parametric investigation demonstrates that the integration of the heat recovery unit significan...
