How Does A Ductless Mini-Split System Work?

ac installation mini splitA ductless mini-split system is one of the best ways to retain the internal temperature in your house or office space regardless of the external climate. These ductless mini-split systems can keep your home warm in winter and keep it cool in summer.

What Distinguishes Ductless Mini-split Systems from HVAC Units

Most homes have an HVAC system (usually referred to as split systems). The split systems have two units; the outdoor compressor and the indoor units. The outdoor compressor is connected to the indoor unit. Copper tubing lines help to disperse the refrigerant between the units. Then, the return and supply duct lines linked to the indoor unit help circulate air within the space.

Return ducts bring hot air back to the indoor unit while cooled air is delivered to the rooms by the supply duct lines. The challenge with the HVAC system is that there are no existing ductworks for older buildings. Many homeowners prefer not to put new ducts because it requires them to break walls and floors. However, the ductless mini-split system solves this challenge. They can circulate air without needing duct lines, unlike the HVAC that requires ducts to dispense air through the indoor unit.

How Does a Mini-Split System Work?

The air handling unit absorbs humid air in the room and uses series of pipes to carry it to the condenser. These pipes bring the hot air in contact with coils that contain coolant. The coils transfer energy to the hot air as it comes in contact with it. While this process goes on, the coolant liquid will be converted into gas. The condenser uses electricity to recycle the gas into a liquid state. The air handler takes the cooked air and sends it back to the room. This process is repeated until the room temperature becomes cool. The indoor unit inside the mini-split system removes the need for ductwork. It just takes in warm air and gives out cooled air.

Benefits of a Ductless Mini-Split System

  • Ductless systems:
    • Are more energy efficient
    • Are easy to install
    • Offer improved air quality
    • Cost less

Ductless mini-split systems are straightforward and flexible. Most mini-split systems come with built-in zonings that allow you to adjust different room temperatures.
