💨 Exhaust Air Heat Pumps (Extracting 70°F Building Waste Air, Winter COP >4.5)

Exhaust Air Source Heat Pump Calculator

Size exhaust air energy recovery heat pumps capturing constant 70°F conditioned air leaving building relief/exhaust louvers: calculate high-lift evaporator heat extraction (achieving winter heating COP >4.5 by maintaining a steady warm heat source even during -10°F sub-zero polar vortex events), and sustainable HVAC retrofit profits.
