You need an air conditioning unit, but you don’t know which one to choose. What you do know is that it’s getting hotter outside and before that heat gets oppressive, you need a way to cool down. Here’s what you need to know.
A Split System
A split system is a type of air conditioner that consists of a compressor unit that’s installed outside. The ones sold by Peninsula Air Conditioning are installed with one or more indoor air outlets. They’re also usually used to cool off one or more rooms. In some cases, they’re used to cool very large rooms, like conference rooms up to 60 square meters. They can cost between $800 to $3,000, which makes them a small to medium-sized business purchase. What’s great about a split system is that it’s easy to mount. They tend to be high wall models so that the indoor unit is mounted high up on a wall for that air flow easily blows across the room. And, because cool air falls, a general cooling effect occurs from the top down, cooling the entire room more or less evenly. Cassette models have the indoor unit mounted in the ceiling and blows the air down.
With a conventional air conditioner, the compressor unit is either on or off. And, these compressors have to work up to 100 percent of capacity in order to run efficiently. Inverters can vary the compressor speed and maintain the set temperature within a narrow range. This increases the efficiency of the unit and they cost much less to run than traditional units.
Cooling-Only or Reverse Cycle
A reverse-cycle unit doesn’t cost a lot more than a cooling-only model, but they can be used for heating during the wintertime. These units can cost more to install, however, but they’re one of the cheapest and more effective ways to heat and cool large spaces. They also cause less carbon dioxide to be produced, thus lowering greenhouse gas emissions.
Wall or Window Units
A wall or window unit is usually installed in a window or external wall and will cool rooms and open-plan areas up to 50 sq meters. Smaller units of this type are plugged into a normal power outlet and are secured in a window frame. Sometimes, a special support system is used so that the unit sits firmly in a window. But, usually, these units can be freestanding. While they exist in the marketplace, they’re not as popular, so there are fewer of them floating around. Window units typically cost between $300 and $1,000.
How Big Of A Unit Do You Need?
Once you’ve decided on the air conditioning model you want, you need to know how big a unit you need. This isn’t always intuitive. Most people mistakenly believe that they need the biggest model they can afford. But, air conditioning units serve a dual purpose. The way an air conditioner works is that is effectively collects moisture from the air, and in the process produces an evaporative effect — cooling the air. This produces the classic “dry cooling” effect you.
Models that are too powerful for the room size might run frequent short cycles, which many people mistake for efficiency. In effect, what’s happening is the unit is unable to efficiently cool the room. And, as a result, the room feels warmer than it otherwise would be. This is because moisture cannot be removed from the area in an efficient manner. The kind of cooling effect it produces is one that’s damp, which tend to make the room feel less comfortable.
What Kind Of Climate Do You Live In?
When you live in a very dry climate, you will need something called a “swamp cooler.” These add moisture into the air. Because dry climates tend not to be very humid, by definition, the cooling effect tends to be too much for the home, and can cause problems for the unit and for you and your belongings. If you live in a humid climate, an air conditioning unit capable of dehumidifying a room is very important. You will want to have the unit checked periodically to make sure the collected water (moisture) is emptied from the unit.
If this is not done, it may not operate at peak efficiency, which means that it will be working harder than it needs to, wearing down critical motorized parts, including the fan unit.
