Comments Off on What is a Mini Split Air Conditioner?
April3     The central heating and cooling systems that are traditionally used in homes are called split systems because they typically have indoor and outdoor components. A mini split air conditioner also has indoor and outdoor components, but it takes up a lot less space than traditional heating and cooling systems. Another key difference is that it doesn't rely on ducts to deliver heated and cooled air.

How Do Mini Split Air Conditioners Work?

Mini split air conditioners work similarly to other types of air conditioners in that they compress and expand refrigerant to pull away heat and moisture from the air. There are some pretty significant differences between mini split air conditioners and other types of air conditioners, and they include:
  • Heat Pumps - How are ductless air conditioners, or mini split air conditioners, capable of heating and cooling without needing large indoor and outdoor units? The secret lies in energy-efficient heat pumps. They take advantage of heat's tendency to move from warm areas to cool areas. In doing so, they are capable of heating and cooling while using a lot less energy.
  • Connections - As with a traditional heating and cooling system, mini split systems have indoor and outdoor components. In this case, however, the indoor and outdoor units are connected by suction lines, which draw away condensate, refrigerant lines, which facilitate the transfer of warm air, and power lines, which keep everything humming along.
  • Indoor Units - With a mini split air conditioner, outdoor units are mounted on outside walls. There are also compact indoor units, which may be mounted on floors, ceilings or high up on walls. These units have blowers that deliver heated and cooled air to a specific area. You can't understand how mini split air conditioners work without understanding that no ducts are involved at all.

Comments Off on How Does Ductless Air Conditioning Work?
April2         Ductless split systems provide targeted heating and cooling comfort when conventional central HVAC equipment is too costly or impractical to install. Widely adopted in Europe and Southeast Asia, ductless technology continues to gain popularity in the U.S. as consumers and businesses look for cost-effective alternatives to window units, PTACs (packaged terminal air conditioners) and inefficient ducted systems.

Basic Components of a Ductless System

So, how does ductless air conditioning work? In many respects, a ductless mini split operates in a similar manner to its ducted counterpart. In the refrigeration cycle, low-pressure gas is transformed into high-pressure gas by the action of a compressor. The heat is dissipated into the outdoors by the action of a forced air fan. The refrigerant then becomes a high-pressure liquid, and it is again changed into a low-pressure liquid by a metering device at the evaporator coil. Heat energy from the indoor air is absorbed by the refrigerant, and the resulting cooler air is pushed into the living area by the internal blower. The resulting low-pressure gas is moved through the suction line back to compressor, and the cycle is repeated again. There are two main elements in a ductless split system installation:

Outdoor Unit

The outdoor condensing unit houses three primary components including:
  • The Compressor: The compressor is the heart of any air conditioning system. It is also the most expensive individual part. The device condenses low-pressure gas into high-pressure gas, so the thermal heat transfer process is completed more efficiently.
  • Condensing Coil: A lattice-like structure comprised of numerous aluminum fins, the condensing coil cycles hot refrigerant and accommodates its conversion from a high-pressure gas to a high-pressure liquid.
  • The Fan: The fan draws air through the condensing coil and helps dissipate the stored heat energy into the outdoor environment.

Indoor Unit

How do ductless air conditioners work? It is important to recognize the distinct advantages of spilt system indoor fan coil units. Conventional central air conditioners employ a single air handler, blower and evaporator coil, which is usually installed in a garage or equipment closet. A complex air distribution network provides an avenue for the delivery of conditioned air into each room of the building from a single point of origin. Unfortunately, ductwork is often inefficient, restrictive, dirty, leaky and noisy. Ductless indoor units include a fan and evaporator coil in the same enclosure. Each unit provides point of use air conditioning wherever it is installed. Stylish cabinets are available in wall mount, duct mount and ceiling cassette varieties. Whether used in single or multiple zone configurations, the indoor units can be strategically positioned to heat and cool one room or an entire building. The versatility and convenience of ductless technology completely eliminates the need for inefficient ductwork. When comparing ductless ac vs. central ac vs. window unit, ductless split systems are quieter, more efficient and offer greater levels of comfort.

Mini-Split versus Multi-Split

In multi-room applications, does ductless AC work? In fact, ductless air conditioners are an excellent choice for both single and multi-zone areas. Systems can be installed in a variety of different configurations based on the following two platforms: Mini-Split: A mini split includes a single indoor fan coil and outdoor condenser. This combination is especially effective for cooling an individual room that has limited load requirements. If there is sufficient space to set multiple condensing units outdoors, several systems can be used in tandem to provide cooling for an entire building. This type of installation provides a separate temperature control for each unit. If there is a malfunction in one system, the rest will continue to provide conditioned air to the unaffected areas. Multi-Split: A multi-split system employs one condensing unit that is connected to several indoor air handlers. In this configuration, an indoor unit is selected and equipped with a thermostat. When there is a call for cooling, all of the units are activated simultaneously. This configuration is cost effective but should only be used in buildings where each room has a similar cooling load. For true zoning in a multi-split application, a single condensing unit must be equipped with separate compressor circuits that are piped to each individual air handler. Every zone is controlled by a different thermostat, so the occupants can tailor the temperature to their individual preference. A Mitsubishi air conditioner designed for multi-split operation can include up to eight different zones.

Ductless Heat Pump How it Works

In the cooling mode, a ductless heat pump operates in essentially the same way as an air conditioner. The inclusion of a reversing valve allows the refrigerant to flow in either direction, which provides both heating and cooling from a single ductless system. When considering the installation of a ductless heat pump, it is important to understand the relationship between heating efficiency and the outdoor ambient temperature. In general, a heat pump operates most effectively in mild climates that rarely reach the freezing point. An electric heat strip can be installed to provide supplemental heat when necessary.

Where Ductless is needed

Ductless air conditioners and heat pumps offer exceptional flexibility and can be modified to fit numerous applications. In addition to existing buildings, mini splits are appearing more frequently in new construction where the low profile of ductless equipment is very compatible with modern architectural design.

An Air Conditioner Small Enough For:

  • Server Rooms
  • Condos
  • Basements
  • Garages
  • Attics
  • Buildings Requiring Supplemental Cooling

An Air Conditioner Quiet Enough For:

  • Hospitals
  • Churches
  • Bedrooms
  • Recording Studios
  • Meeting Rooms

An Air Conditioner Powerful Enough For:

  • Office Buildings
  • Multi-Tenant Buildings
  • High Rise Buildings
  • Hotels
  • Data Centers

High Efficiency Perfect for Everyone

Ductless split systems offer exceptional versatility, low noise and enhanced levels of comfort. Through the use of exclusive inverter technology, ductless air conditioners have the highest SEER ratings in the industry. Many consumers ask, “How much does ductless AC cost?” By eliminating the need for an air distribution network, a ductless air conditioner saves substantially on labor and installation costs. Mitsubishi contractors invite you to explore the many benefits that an efficient ductless split system can provide.

Comments Off on What’s a SEER?
April1  
SEER stands for Seasonal Energy Efficiency Ratio.
Every system (composed of an outdoor compressor bearing unit that matches with an indoor unit) is evaluated and then given an Energy Efficiency Rating. This is a lot like the miles per gallon rating that your car gets, but instead of gasoline it is a number that is used to calculate your energy savings. The more cooling/heating a system puts out for each unit of energy it consumes, the higher rating it will receive. The higher the efficiency rating of your system, the less energy it will consume…that means lower utility bills and less of an impact on the environment.
So shouldn’t I just go with a higher SEER value?


At first glance you would think that the higher the SEER value the better, however that’s not always the case. You will definitely be saving more energy when operating a higher SEER system, but you might not be saving money overall. Typically, the higher the SEER value the higher the cost of the system (all other things being the same). There are really two determining factors for you when choosing the SEER value for your system: the length of time you plan on being in your home and your preference to be environmentally friendly. If you have the conviction to be as green as possible no matter what the cost is then you want to go with as high of a SEER value as possible. We wish everyone could choose this option. However, the reality is most people want to be environmentally friendly but must also live within a budget. The good news is that as technology advances our heating and cooling will require less and less energy.


So how do I determine which SEER value is for me?


The determining factor in finding the right SEER value for your HVAC system is how long you plan on living in your current house. Follow along with this example to understand this better:


The minimum SEER value allowed is 13. That will serve as our base. Here are the annual operational costs of an average family for various SEER levels. These values will change depending on a number of factors including your utility company and how high or low you keep your indoor temperature among other things.


13 SEER = $805.00
14 SEER = $747.50
16 SEER = $632.50
23 SEER = $448.50

Now at first glance it looks like a no-brainer. The 23 SEER system costs nearly half as much to operate as the 13 SEER system. However, the 23 SEER also costs significantly more (sometimes twice as much) as the 13 SEER system. So let's just say for the sake of the example that a 13 SEER system costs $4000 and a 23 SEER system costs $8000. You would need to be living in your home for over 11 years before you began to save money on that system. So if you are planning on living in your current home long-term then this would be a great investment for you, especially on year 11 when you start saving almost $400 a year! However, if you are living in a starter home and plan on moving in a few years, while a higher SEER system will add value to your home for resale, you might want to consider a lesser SEER value for upfront savings.

Comments Off on UPSTAIRS, DOWNSTAIRS: CONDITIONING MULTIPLE ROOMS WITH HOME ZONING

mar3

Finding a home that requires the same amount of cooling and heating throughout is a challenge. In fact, it’s probably impossible. Basements, attics, first floors, second floors, fronts, backs – all have unique needs based on the home’s size, windows, facings, insulation, doors and even the home’s position towards the sun. In the past, it has been difficult to mitigate these differences. Homeowners were simply forced accept the fact that some areas of the house would be comfortable, while others would not.

Total Home Comfort Can Be a Reality

When the only option for modern cooling and heating was a ducted central HVAC system, the reality of the uncomfortable home was normal. In recent years, however, there have been significant advances in cooling and heating, including zoning.

A zoned home is divided into segments based on each area’s need for conditioning. Rather than relying on a single unit to cool or heat the entire property, multi-zoned homes utilize a network of small, energy efficient units and thermostats to send the right amount of conditioned air to each zone. This allows homeowners to have room-by-room control.

Homes that can benefit from zoned systems include:

  • Homes with two or more stories
  • Homes with finished, livable basements
  • Rooms that get blocked off in the winter or summer because of comfort issues
  • Rooms with large windows or high ceilings
  • Large families that often find themselves battling over the thermostat
  • Older, historic homes in which traditional ductwork is implausible

Zoning Provides Room-by-Room Comfort Customization

The number of zones a home can benefit from will depend on its size and layout. In some cases, a single zone can cool or heat an entire floor. In others, a multi-room system would be used to divide the home up into several temperature control zones. The greatest benefit of zoning is the level of customization that can be achieved. You can cool and heat only the zones in use, which not onlyimproves personal comfort, but reduces overall energy consumption and costs.

While ducted HVAC systems can be “zoned”, they never quite achieve the same level of customization and precise control that is possible with a ductless system. When every segment of the house is manageable by its own unit, it means that every room of the home and every family member in the home can achieve total comfort, no matter what time of day or time of year
