Heat Pump Principle of Operation

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.
IMPORTANT

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.
