A residential ductless heat pump is a type of HVAC system that uses refrigeration and electrical energy to heat and cool a building. There are two primary parts:
- A condenser, which is generally located on the building’s outside.
- An air handler unit, the evaporator, is located within the building.
A refrigeration line connects the two units of the heat pump system, which transfers hot or cool air into the house. Because the condenser and air handler are separate components, this system is commonly referred to as a mini split system.
A multi zone ductless air conditioning unit has several indoor units that are spread all across the building and are supplied by a single outdoor unit.
The Difference Between a Ductless Mini Split Heat Pump and a Furnace
The main difference is that furnaces create heat by burning fuel, such as oil, gas, or propane, whereas heat pumps generate heat by utilizing electricity.
If you live in a region where electric power is reasonably priced, you might consider installing a heat pump as a new heat source. They are ideal alternatives to furnaces and air conditioners since they can provide cold air in hot times.
High efficiency heat pumps also dehumidify better than ordinary central air conditioners, resulting in lower energy consumption and greater cooling comfort throughout the summer season. They may be utilized in sub-zero temperatures thanks to recent improvements.
How Air Source Heat Pumps Work
Take a look at your refrigerator or freezer to see how this works. It transfers heat from the inside of the box to the exterior. A thermostat within the box maintains a constant temperature, and when the box becomes too warm, it begins to pump heat out of the box. When the box cools and reaches the temperature selected, the pumping stops until the interior heats up again.
During the summertime, your heat pump in cooling mode utilizes R-410A, a refrigerant to remove hot air from your home and discharge that heat into the outside air. In the winter, it works like a reversed air conditioner. In ductless systems the refrigerant absorbs heat from the outside air and transfers it to your home.
This heat is transferred by the refrigerant line to the indoor unit, which then distributes it to the air inside your house via a fan within the interior unit. Heat pumps are indeed very energy efficient heat sources. They transfer heat rather than generate it. In fact, when compared to electric resistance heating such as furnaces or baseboard heaters, a heat pump may cut your power consumption by half.
