If you’re looking for an air conditioning system that provides targeted cooling and heating comfort, then you definitely should consider purchasing a ductless air conditioner. Ductless mini split air conditioners are convenient for most American homes as they’re easy to install and not expensive to buy or maintain. In fact, you can install your own ductless air conditioning system and only call an HVAC professional to confirm that you have installed everything perfectly.
Over the years, mini split systems have grown in popularity in Southeast Asia and Europe as well as the United States. This growth is driven by the benefits that a ductless air conditioner present to homeowners as well as businesses.
Compared to packaged air conditioners and window air conditioning systems, mini split systems offer far more convenience.
The indoor units are available in various stylish cabinet designs including ceiling cassette, duct mount, and wall mount.
During the refrigeration cycle, the compressor converts low-pressure gas into a high-pressure gas. The forced air fan then dissipates the heat outdoors. Next, the refrigerant becomes a high-pressure liquid which is once again changed into a low-pressure liquid by a metering device located at the evaporator coil.
The refrigerant absorbs the heat energy that is indoors and the mini split’s internal blower pushes cooler air into the house.
When the refrigerant in its liquid state absorbs the heated air, it becomes a low-pressure gas that moves through the suction line and back to the compressor. Hence, a cycle is established.

Components of A Ductless System
A ductless system consists of two main parts:- The indoor unit
- The outdoor unit
Indoor Ductless Unit
The indoor unit includes an evaporator coil and fan that are contained within the same enclosure. The indoor AC system can either be a single-zone ductless mini split air conditioner or it could be multi-zone. Each indoor unit is able to provide separate air conditioning though they are all connected to the same outdoor unit.
The indoor units are available in various stylish cabinet designs including ceiling cassette, duct mount, and wall mount.
Outdoor Ductless Unit
The outdoor unit consists of three parts, all of which are contained in the condensing unit. They include:- Compressor
- Condensing Coil
- Fan
The Compressor
The compressor is at the core of every conditioning system. It is also the most expensive part of the condenser. The compressor converts low-pressure gas into high-pressure gas via condensation. This enables a more efficient heat transfer process.Condensing Coil
The condensing coil is designed in a lattice pattern and is made up of aluminum fins. It is responsible for facilitating the conversion of hot refrigerant from a high-pressure gas to a high-pressure liquid.Fan
The fan is responsible for dissipating the heat energy into the outdoors as well as drawing air through the condensing coil.How a Ductless Air Conditioning System Works
In many ways, Mitsubishi ductless air conditioning units like the MITSUBISHI 25,000 BTU 20 SEER TRI ZONE HEAT PUMP SYSTEM 6+6+9 operate in a similar way to ducted conditioning systems such as central air conditioners.

Understanding The Difference Between Mini-Split and Multi-Split
Mini-Split Ductless Air Conditioning Systems
A mini-split has a single outdoor condenser and a single indoor fan coil. This configuration is perfect when cooling a single room that does not have excessive load requirements. In case there is enough space to place more than one condensing unit outdoors, several units may be used together to provide cooling for a whole building. When you use this kind of installation, you will have separate temperature control for each unit. This is beneficial because in case there is a malfunction in one of the units, the rest will not be affected and will continue to work.Multi-Split Ductless Air Conditioning Systems
A multi-split system comprises of one condenser unit that is connected to more than one indoor air handler. This configuration uses a thermostat to select an indoor. Once a call for cooling is made, all the units are activated simultaneously. Even though this configuration is cost-effective, it should only be used in buildings where every room has the same cooling load. In order to achieve zoning using a multi-split ductless air conditioning system, the condensing unit will have to be fixed with individual compressor circuits that are piped to separate air handlers. Using multi-split AC systems allows occupants of different rooms to regulate the temperature of each separate room using a thermostat for that room.How A Ductless Heat Pump Works
When set to cooling mode, a heat pump works in the same way as an air conditioner. By including a reversing valve in the heat pump, the refrigerant is able to flow in either direction. This allows for it to provide cooling and heating from a single ductless system. It is important to understand that a heat pump is most effective when used in mild climates. If necessary, you can use an electric heat strip to provide supplemental heat.March 23, 2018
