If you’re in the market for a cooling system upgrade, check out heat pumps for their cooling power and energy efficiency, as well as for providing primary heating on moderately cold days and supplemental heating in dual-fuel systems on frigid days.
Benefits for all seasons
Heat pumps and air-conditioning systems use refrigeration principles to transfer heat from the living space of a home to outside the home, leaving the indoor air cool and comfortable. During the heat-exchange process, moisture condenses on the cooling coil and drains away. This helps keep indoor humidity within optimal range for greater comfort.
Heat pumps and air conditioners differ in that heat-pump systems are designed with a reversing valve that reverses the direction of the refrigerant to provide home heating during the heating months, making them ideal for all seasons.
For Cleveland-area homeowners, heat pumps provide energy-efficient heating down to the heat pump’s balance point, which is typically around freezing (high-efficiency systems deliver efficient heating below the freezing mark). The furnace in the dual-fuel system takes over home heating when the heat pump loses efficiency, or can be manually kicked on if natural gas prices are especially low (as they have been over the past year or so).
Heat pump cooling basics
Heat pumps use refrigeration principles of extracting and releasing heat under pressure changes that manipulate the refrigerant’s temperature. Pressure changes instigate refrigerant to become very cold, thereby “attracting” heat from warmer air, whether the warmer air is inside the home (cooling months) or outside the home (heating months). These are the basics of heat pump cooling:
- Refrigerant flows into the indoor cooling coil (evaporator) under low pressure.
- The refrigerant extracts heat from indoor air as the refrigerant boils to a vapor.
- The vaporized refrigerant flows to the compressor via the reversing valve.
- The refrigerant is squeezed and heated by the compressor.
- The hot vapor refrigerant flows to the outside condenser.
- Under high pressure, the refrigerant condenses to a liquid and releases heat outside the home.
- The refrigerant returns to the coiling coil to repeat the process.
