How Ductless Air Conditioning Works

For years, ductless air conditioning has been used in Japan and a few other developed countries, but it is only recently that it has been introduced to other parts of the world.

They can be used in schools, multifamily houses, restaurants, auditoriums, cinema theaters and office buildings among other types of establishments.

Ductless split ACs are also known as mini-splits and they have two main components, a compressor and an air handling unit, which consists of the evaporator and fan.

The condenser and compressor make up a single unit, which is normally placed outside the building. The evaporator unit and fan also make up one unit which is often wall-mounted inside the room to be cooled. The indoor and outdoor units are connected by power cables, refrigerant tubing and drain pipe.

While split AC systems have several advantages over central air systems, they also have a number of disadvantages. Two of the main advantages of ductless air conditioners are that these systems do not require any duct-work, and secondly, they are very quite when in operation.

These systems are normally used for zone cooling and can be very energy-efficient as different zones are cooled independently. Mini-split systems have Seasonal Energy Efficiency (SEER) Ratios of 10 to 11.5.

They come in a wide range of options to suit different types of decors. Additionally, these systems also help to secure the home from intruders and robbers.

The main downside of ductless air conditioning systems is the fact that they are costly to procure. These units often cost between $1,500 to $2,000, which is almost double the cost of procuring window systems.

Secondly, these systems cannot be installed just anywhere. The air handling unit must be placed strategically, so the installer must identify a suitable location.

If the unit is too small or too big for the room and it’s location is poorly chosen, it may draw too much power to cool the room, leading to increased energy bills.

Ductless systems should also be fitted with the right equipment to drain the condensate to ensure that walls are not stained by condensing water.
