Air Conditioning Jargon Part One |
To make an informed choice when you go to buy an air-conditioner you need to know exactly what the salesman is talking about. All air-conditioners are not created equal, but what is the difference? Here is an explanation of the different types that you may not be completely familiar with.
• An evaporative cooler passes air over a wet pad of some kind to cool it down before blowing it into the room. It uses fresh air from outside and is cheap to run, but noisy and not as efficient as refrigerative types.
• A portable evaporative cooler is not attached permanently to the building, but is very heavy - and noisy.
• Indirect evaporative coolers reduce humidity - a problem with evaporative types - by separating air, but the difference is not that noticeable when the humidity is high.
• Refrigerative air conditioners basically work like a refrigerator by compressing a refrigerant. Expensive to run so the cost is reduced by re-circling air rather than introducing fresh air to the room.
• Reverse cycle air conditioner is the same as above, but can also be used for heating purposes. Since hot air rises and they are installed up high, heating efficiency is compromised.
• Portable refrigerative air conditioner can be moved around, but doesn't come with reverse cycle abilities. Performance is not as good as non-portable.
• Room air conditioner (RAC) is an old-fashioned refrigerative air conditioner consisting of a box put into the wall. Everything is in the box so it is very noisy. | | Author Info: Find out more about residential room air conditioners and the Gen III system at Advantage Air (http://www.advantageair.com.au). |
