WINTER HEATING

1.Outdoor air enters heat pump.

2.Cold, heat-transfer section (outdoor coil) extracts heat from outdoor air as refrigerant evaporates from a liquid to a gas.

3.Refrigerant, compressed to a hot gas by heat pump, carries the heat to the hot heat- transfer section (indoor coil).

4.Hot, heat-transfer section (indoor coil) releases the heat to indoor air as refrigerant condenses from a gas to a liquid.

5.Air handler circulates the heat throughout the home.

6.Refrigerant returns to outdoor coil and evaporates once again to absorb more heat.

SUMMER COOLING

1.Indoor air enters the air handler section.

2.Cold, heat-transfer section (indoor coil) extracts heat from indoor air as refrigerant evaporates from a liquid to a cold gas.

3.Refrigerant, drawn to heat pump and compressed to a hot gas by heat pump, carries the heat outdoors.

4.Hot, heat-transfer section (outdoor coil) releases the heat as refrigerant condenses from a gas to a liquid.

5.Heat pump (outdoor fan) discharges the heat to outside air.

6.Refrigerant returns to indoor coil and evaporates once again to absorb more heat.
