Ductless Split Air Conditioner - Advantages of Using Ductless Air Conditioning

Ductless split air conditioners have been manufactured and used in Japan for many years and it has been recently introduced in other countries also. They are mainly used in multi family houses, schools, office buildings, restaurants, cinema theaters and auditoriums.

The Ductless split air conditioners also commonly known as "mini-splits" like the central systems have two units - an air handling unit which includes a fan and an evaporator and a compressor.

AIR CONDITIONER

The compressor and the condenser comprise one unit and are placed outside the house. The fan and the evaporator unit are placed in the room that has to be cooled. These both units are combined using a conduit that has the power cable, drain and the tubing.

These split air conditioner systems have several advantages and limitations. The advantages are that it can be easily installed i.e. we need not make any ducts on the walls, the operation of the air conditioner's compressor doesn't produce much noise and it gives a quiet environment.

These systems provide zone cooling facility and help in energy saving using the thermostat that helps in controlling the zones independently. The Seasonal Energy Efficiency ratio of the Ductless split air conditioning systems are in the range 10.0 and 11.5.

They also provide a wide range of options for the interior designing. They also help in making the building safe and secure from the robbers and intruders.

The major disadvantage of these ductless split air conditioner systems is the cost of the system. There are priced in the range of 1500$ to 2000$ per ton which is nearly twice the price of the window systems.

These systems can't be installed at any random place. We have to choose a proper location for placing the air handling unit. If it is not positioned at a proper place or if doesn't have a proper size, there are possibilities of the air bouncing between the walls resulting in a short cycle of the air and we won't have good cooling effect and lot of energy will also be wasted in this case.

These systems should also have proper facility to drain the condensate else it would lead to staining the building walls.

significant Air Conditioning Maintenance - A Step by Step Guide

If you have a ductless wall split air conditioning unit, you should be cleaning the filters at least once every 3 months if not more often. Below is a step by step guide on how to clean you wall split's (ductless unit's) filters.

Your ductless reverse cycle unit can be cleaned and maintained undoubtedly by the homeowner. Firstly make sure the power to the unit is switched off. Open the lid using two hands by pulling the front panel towards you. It should pivot from the top. Be diplomatic and don't force the flap as you could break it.

Lift the face up gradually and gradually using both hands. The panel should lock in to place when it gets to the top of the pivot point. If not have man hold the lid open for you.

The filters will be settled just underneath where the front cover was. They are shown here as white mesh that looks like a fly screen material. Remove the filters in two actions. Firstly push them up slightly to push the base over the clip. Then pull the filters down and out of your air conditioner.

Once the filters are out there are two ways to clean them. You can whether vacuum them or wash them in warm soapy water. Warm soapy water works best as it does a more suitable cleaning job. Be diplomatic with the filters and gawk for any wear and tear. If the filters look damaged, speak to the constructor to organise transfer filters.

Once clean, leave the filters in a dry place inside your home to dry. Do not place to dry in the sun as they may warp and you will not be able to get the filters back into the air conditioning unit.

Wait until the filters are thoroughly dry before inserting them back into the ductless/wall split air conditioning unit. Give the exterior of the air conditioning unit a quick wipe down with a moist (not wet) cloth to Remove any dust. Once this is done, replace the front panel, turn the power on and you are ready again to use your ductless/wall split unit.

Portable Air Conditioners

An air conditioner on wheels is called a portable air conditioner. It is used in homes and offices and can easily be transported. They come as two types - split and monoblock. Twin pipe units are the best because in the single duct unit air is pumped out of the room and replaced by hot air from the outside reducing its effectiveness.

air conditioner window

Portable air conditioners are an alternative to window or wall units and are good to use in apartment buildings that don't allow window units or in homes that have windows that are inappropriate for window models. Since they are portable, they are real easy to roll in and start up. However, they can be heavy weighing between 50 and 80 pounds.

Portable air conditioners are more expensive than window models. They average about 0 more than comparable window units. Some are more expensive because they dehumidify a room as well as cool it, and many can be used as fans, while others can be used as space heaters as well. Because they are more expensive, it is usually smart to buy a portable air conditioner that has functions that can be used throughout the year, making it more cost effective. Portable air conditioners are available at 6,000 to 8,000 BTUs. There is little price differentiation between the smaller BTU units or the larger 10,000 and 12,000 BTU units. One fact to note is that a portable air conditioner requires more BTUs to cool a room than a window model. If you are cooling 300 square feet, you'll need about 10,000 - as opposed to 8,000 if you were using a window model.

Air Conditioner Freon Leak Repairs

During the summer months one of the most common problems with air conditioning systems is getting low on freon. This is a problem that normally ends with the air conditioning contractor putting a few pounds of freon in and calling it quits. This is not the correct way to solve the solution, and never a repair that will last forever. By going through the next steps I have provided in this article you can guarantee your air conditioner will work next year.

The way an air conditioning system works is by using a refrigerant (freon) and letting it change its state to take the heat out of the air. This refrigerant is in a sealed system which should never have to be replaced or recharged. When a proper installation of an air conditioner is performed the contractor should put a vacuum on the system to check for any leaks. If there is a leak in the system it needs to be found and repaired. This is where the problem normally comes into effect. during the installation process either someone had a bad braze weld or didn't put a vacuum pump on and there is a leak.

AIR CONDITIONER

This leak could go undetected for a few years and by the time the customer notices it there is no more warranty on the product or installation. When another contractor comes in to look for the problem they just fill it up and take the easy money. This charge to fill with freon can range from 0-5 and after doing that a few times the customer can spend more than the system is worth. Not to mention the damage the low freon will do to your compressor and cause future problems.

The proper thing to do in the case of a loss of freon is very easy, and after the fix you can be sure that you will never lose freon again.

What you need to see the contract rod is put the system into a positive pressure using nitrogen. By putting that much pressure in the system you will be able to hear the nitrogen leak and repair the problem. If the problem is in the outside or inside coils you need to have them replaced. Hopefully the leak was in one of the original welds and can just be touched up. After the repair there needs to be a vacuum put on the system. By bringing the system to a negative pressure you remove all of the noncondensables and any moisture in the system. Let this vacuum sit for an hour and see if there is any loss. If not recharge to factory standards and you air conditioning system will work well for a long time.

How to Fix a Broken Air Conditioner

A faulty or broken down air conditioner can be a big annoyance, especially as it normally breaks down in the heat of summer in the middle of the say. Air conditioners can fail for a range of dissimilar reasons. Below is a checklist of 5 troubleshooting points that may help you get you air conditioning theory up and running again.

1) Clean The Return Air Filter - A dirty filter can whether sell out the production of an air conditioner or even damage the theory if it becomes very blocked. A uncomplicated clean of the filter can surely get your theory up and running again. You should aim to clean your filter every few weeks or as needed.

2) search for The Controller - Owner error is the main intuit an air conditioning controller can cause the theory problems. Some things to check are to see if the controller has batteries, check the climatic characteristic set on the controller and check to see if heating or cooling is chosen. All these things can cause an air conditioner to not work correctly. Also be wary of adding timers and programs unless you know how to use and set your controller. If you are at all unsure about the controllers operation, speak with the firm that installed your system.

3) Check The Compressor Coil - If your hvac theory is not running, check colse to the compressor for damage. Anyone that looks unusual or even sounds unusual can be a sign of damage. Be sure to check to make sure that the coils are not obstructed by Anyone and make sure nothing is stuck in the fan.

4) Reset The Power - Try restarting the unit to fix an air conditioner that has stopped working. Naturally turn the unit off at the meter box for about a wee and then restart. This quick and uncomplicated trick has been known to restart a theory many times.

5) Look At The Ducting - With central air conditioners or ducted units, be sure to get up into the roof to search for the ducting. Look for any lose fittings that may be causing problems. Also check that the duct runs are level as any sharp bends can restrict airflow.

Try these 5 hvac troubleshooting tips and hopefully you should be able to get your hvac theory up and running again. If you still have problems after trying these 5 points, it is time to call in an air conditioning contractor.

Swamp Cooler vs Air Conditioner

Although swamp coolers and air conditioners were invented to turn hot air into cool, the science behind each formula is quite different.

What is a swamp cooler?

DELONGHI PINGUINO PORTABLE AIR CONDITIONER

It's just other name for an evaporative cooler. Water is used to wet absorptive pads colse to the sides of the cooler. A fan or "squirrel cage" draws surface air through the pads and the air is cooled as the water in the pads evaporates. The major benefit of this type of cooler is that you only need to power a water pump and a fan to draw the air through the pads.

They typically use between three and 10 gallons of water per day. That's equivalent to a few toilet flushes or, on the high end, a short shower.

Unless the relative humidity is lower than 30% or so, swamp coolers are not very effective. They work well in the southwest, west Texas, and parts of Idaho, Washington, Colorado, Wyoming, and Montana. In those areas you should be able to perform a 20 degree differential between surface and inside.

Also, for a swamp cooler to remain effective it must exhaust as much air as it takes in. This means retention a window open. If you don't, the humidity will rise and so will the climatic characteristic of the air blown from the cooler.

Air conditioning, on the other hand, is favorite because it will reliably dehumidify and cool the air, no matter where you live. This how an air conditioner works:

The compressor compresses cool Freon gas, causing it to become hot, high-pressure Freon gas. This hot gas runs through a set of coils so it can dissipate its heat, and it condenses into a liquid.
The Freon liquid runs through an expansion valve, and in the process it evaporates to become cold, low-pressure Freon gas. This cold gas runs through a set of coils that allow the gas to suck in heat and cool down the air inside.

Mixed in with the Freon is a small number of lightweight oil that lubricates the compressor.

Swamp cooler vs air conditioner: which is cheaper to operate?

In our cordial contest the swamp cooler wins handily. For similar sized units, even an air conditioner with and power Star rating uses 4-5 times the power needed to run a swamp cooler.

The discrepancy is the number of power required to power an air conditioner compressor versus the galvanic motors used in a swamp cooler.

Which is better for the outdoor environment?

Unless you believe that soon to be outlawed R-22 refrigerant leaking into the climate from your air conditioner is a good thing, the swamp cooler wins again. The swamp cooler maintains a Green profile by mimicking nature's way of cooling.

The way in which an air conditioner or swamp cooler affects the indoor environment of your home is considered by the way it circulates the air. Although an air conditioner re-circulates the same air, this is helpful in controlling allergens such as dust and pollen.

Since an open window is principal when running a swamp cooler, you'll be letting in what the air conditioner keeps out.

Swamp cooler vs air conditioner: Which one wins?

I think swamp coolers are a good choice since they're relatively less high-priced and much cheaper to control than air conditioning as long as you live in Phoenix, Arizona. But if you call tiny Rock, Arkansas your home, nobody's going to talk you out of your air conditioner.

Ductless Split Air Conditioner Review

Ductless split air conditioning units are the very best thing for some situations. Of course they can be installed in the place of most any central air unit. They also are a very good alternative to window air conditioning units. I will explore the use of these units more closely and look at how they can be used effectively.

air conditioner window unit

One of the many problems encountered by the professional is when they are asked to install central air in an older home that was never designed with air conditioning as even a possibility. The walls may be very thick stone. Often they have very little or no insulation. The floor structures may be rough cut lumber. The joists spacing may be random.

AIR CONDITIONER

Walls and ceilings are plaster and lathe. Basically everything is stacked against any type of ducted central air conditioning. Many log style homes also are not very easy to get any kind of ducted central air installed. The open ceilings and the bare log wall design does not allow for any kind of ducting. I'm sure there are other situations. These are the ones that I have come across most frequently.

If you have a home or building that falls into one of these categories you may want to investigate installing a ductless air conditioner. This type of air conditioner can be installed in almost any home or building. The small indoor unit can be attached to the wall with a few screws. Most of the units only require that a three inch hole be bored through the outside wall. In new installations the units can be placed on inside walls with some fore thought and planning. For installation in older homes or homes that are already built you will want to plan the units to be on the outside walls.

The outdoor condenser units can be placed up to one hundred feet away from the indoor units. One outdoor unit can be used for many indoor units. Up to four indoor units can be attached to the same outdoor condenser. Some very advanced electronics will control the operation of the condenser and compressor to supply the refrigerant to the indoor air handler units that are running at the time. With variable speed technology the compressor and the condenser fan will only run as fast as needed. This technology has become very efficient in the last few years. You do not have to give up any efficiency with these ductless split units.

Another advantage to these mini split air conditioners is that they can be controlled to run only in the rooms that you actually need air conditioning in. If you are not going to be in a room you can shut down the unit. The units also have timers that can be set to turn the air conditioning on or off at preset times. If you are not going to be home all day the air conditioning can be setback or turned off.

The timer will turn on the air conditioning so that you return to a cool house. Central air conditioning is very hard to zone effectively. Also with large central air conditioning systems the outdoor compressor will be running at full capacity even though only a few rooms may be calling for cooling. There are some central air conditioning systems that are do some staging and variable speed technology. These are not as efficient or as effective as the ductless split technology.

Ductless split heat pumps are another great idea to look at. For a few dollars more you can also very easily have heat from your air conditioning mini split. Then especially in the mild spring and fall weather you can have some very efficient heat with out starting up that big monster of a furnace or boiler in the basement. In southern climates the heat pump version of the ductless split system may provide enough heat year around.

Ductless split air conditioning is definitely something that can solve many problems for some homeowners. Add to that the many advantages of these units and you will find that they are worth every penny that you will invest into them. As with any project like this make sure that you screen your contractor. These units are not for do it yourself people. There are many things that need to be done correctly for these units to work properly and efficiently. A refrigeration license is also required to install these air conditioners.

By doing a little research and hiring the right person you will enjoy many years of trouble free service from your new ductless mini split system.
