As there are no ducts, these systems do not have the air leaks, heat gains or pressure imbalances that can undermine the efficiency and comfort of a centralized air installation. It is much easier and faster to fish a narrow bundle of insulated coolant lines through a house than to adapt bulky HVAC ducts. Beware of installers who size a split air conditioning unit according to a general rule. Most of the time, the result is large equipment that is expensive to operate and cannot effectively reduce humidity levels.
Instead, insist on a “manual calculation of the heat load of J. Calculates system size based on mathematics and factors such as weather, insulation levels, and sun exposure. In simple terms, ductless air conditioning systems (also known as minisplit) connect individual room units with an outdoor compressor. The indoor unit contains refrigerant-cooled evaporator coils.
The warm air in the room blows and is sucked in by the coils. From there, the coolant transfers all indoor heat to the outdoor unit. Ductless air conditioners are characterized by exceptional efficiency, quiet operation and unique flexibility. Instead of a central indoor unit connected by long stretches of ducts that carry warm and cold air back and forth, a mini-split system places small units directly into each room, which draw warm air and send it back as cold air.
The difference with a ductless air conditioning system (see illustration) is where the air is cooled and how it is distributed. As homeowners enjoy the many benefits of zoned heating and cooling, they are impressed by the relatively low cost of installing ductless air conditioning. Mitsubishi Electric contractors are factory-trained and have the knowledge and experience to install ductless air conditioners professionally, economically and with minimal disruption to the customer's lifestyle. Ductless air conditioners (also known as minisplit) give homeowners considerable control over the temperature of individual rooms in their home and can reduce annual home cooling costs by up to 50%.
Before installing a new ductless air conditioner or changing the existing system, it is important to understand how they work. Since the design of the air conditioning system is not limited due to cumbersome ducts, the air conditioner can be supplied to virtually any space simply by installing a stylish ceiling or wall mounted indoor unit. Central air systems send coolant to a bulky central air handler which then blows cool air into the house through a ductwork. After comparing maintenance requirements and operating expenses, many homeowners come to the conclusion that their concerns about the price of ductless air conditioning were unfounded.
Each split air conditioning unit works as a miniature air handler, supplying cool air to its own area only when needed. Installing a ductless air conditioner is definitely a job for a professional technician, as installations may involve improving the electrical capacity of your home or requiring the use of carpenter's tools to cut gaps that the coolant liner can pass through. At first, ductless systems were simple, single-room, often installed as substitutes for window air conditioners. For the highest level of performance and efficiency, Mitsubishi offers a full line of ductless HVAC equipment designed to meet any heating and air conditioning challenge.
By eliminating air distribution materials and associated labor for installation, the cost of the ductless air conditioner is often competitive with conventional air conditioning systems. .
