Difference between Ducted and Ductless Air Conditioners:
The cooling and heating systems in homes are basically divided into two categories, one is ducted system and second is ductless air conditioning Ductless air conditioners comprise two two main parts; one outdoor condenser and an indoor unit(they can be more than one. In ducted system, ducts are hidden in walls and air is delivered to each room through vents. In ductless systems, the outdoor unit directly sent the refrigerant to every indoor unit mounted on the ceiling of the room.
Ductless, mini split-system air-conditioners (mini splits) have many important uses in residential, commercial, and institutional buildings. Mostly they are used in the multifamily houses where separate cooling unit is required in every compartment of the house .And also in those houses where ducting is not initially done for the ducted systems. And they can be the best choice for every place where ducting is not installed.
A ductless system has many advantages over ducted system, which make it more attractive than a ducted system to a homeowner that he should buy it instead of performing too much on duck-work and then ducted unit. Some of the benefits and concerns are listed below:
1- Easy Installation:
Ductless mini split systems are easier to install than other types of air conditioning systems. Like for connecting the indoor and outdoor unit with each other, no large amendments are required in your house, just 3 to 4 inches hole would be enough. Additionally, most manufacturers of this system can provide a variety of lengths of connecting outlets. So, if indispensable, you can detect the outdoor unit as far away as 60 feet from the indoor evaporator. This makes it potential to unruffled lodgings on the anterior side of a building house with the compressor in a more advantageous place on the outer side of the building.
2-Ability to cool the home by specific zones:
Another advantage of mini splits are their insignificant size and elasticity for zoning or heating and cooling specific zones. Almost every mini-split air conditioner can be responsible for the capability of handing up to four indoor units with a single outdoor unit. Every indoor unit can work according to the conditions required by the users by adjusting the thermostat of their indoor unit. This systems saves that extra money that should be spent on buying outdoor units for each indoor unit individually.visit this page for available news.
Concerns with Ductless:
● Overall reduced indoor air circulation and increased humidity can lead to comfort and air quality problems.
● Appearance of the air unit on a wall or ceiling in each room.
● Higher cost of ownership for a whole-home solution if your building already has central air conditioner.
● External refrigerant lines which could cause energy losses and aesthetic concerns.
● Service availability and ease of repairs could be a problem as the unit gets older.know more details about this at http://www.lohud.com/story/life/home-garden/2015/05/25/ductless-air-conditioners/27933667/
A ductless system is not recommended for most homes. Trained installers of hvac for mini splits may not be easy to find. Additionally, proper professional hvac workers use expensive tools specially designed for these maintenance. They need to charge for these to earn a return on their investment, so they would not suggest ductless systems except where a ducted system would be hard for them to install.
