1269 Heat Pump Evaporator Coil Grabbing Heat from the Outside Air - Heat Pumps -

Image Text: When the heat pump is running in heating mode, the expansion device turns the Freon into a low temperature, low pressure liquid that enters the outside coil > outside air blowing across the coil boils the Freon from a liquid into a gas > in the conversion from liquid to gas, heat is absorbed from the outside air > the warmed Freon (now a gas) heads back to the condensing coil > flow direction > cool Freon gas (e.g., 35 degrees Fahrenheit) at low pressure > evaporator coil > outside air blown across coil at 45 degrees Fahrenheit > Freon boils > cold air discharged into outside atmosphere at 30 degrees Fahrenheit > flow direction > expansion device > cold Freon liquid (e.g., 20 degrees Fahrenheit) at low pressure
