air conditioners and heat pump


Why are rating numbers important for an air and heating unit?
Rating numbers indicate the efficiency of heating and air conditioning equipment and are directly related to the amount of energy a specific model uses. The higher the rating, the more efficient the product, and the lower your heating and cooling bills can be. The federal government establishes rating guidelines and sets minimum efficiency levels. For cooling, the rating is SEER (Seasonal Energy Efficiency Ratio). For heat pumps, the rating is HSPF (Heating Seasonal Performance Factor). Gas furnaces are rated with AFUE (Annual Fuel Utilization Efficiency).
www.air-and-heating.com provides with energy efficient ac systems directly from the manufacturers, at lowest possible price. Replacing your home/office's heating and air conditioning system is a major decision, but you need to think more than just about the initial purchase price. Factor in how much you can save on your current energy bill by replacing your older system with a higher efficiency system. We help you save while your purchase, as well as after your purchase.

    How does air conditioning work?

  • An air conditioner is a device which uses a special type of substance which readily changes from its normal gas state to a liquid one. The gas is contained in a closed circuit of pipes connected to a pump. The pump compresses the gas so hard that the pressure is great enough for it to turn into a liquid. In doing this the gas/liquid has got hot (If you try to compress a gas, it will almost always get hot - think of a bike pump when you pump up a tyre (tire), the greater the pressure in the tyre, the hotter the pump gets)

    Now the hot liquid travels round a set of pipes which allow the heat to escape. Next the liquid under pressure passes through a valve into a pipe where the pressure is much lower, and the liquid evaporates back into its gas state. In doing this it needs to take in heat from its surroundings, thus making the pipes colder. The gas now gets back to the pump and the whole cycle starts again.

    The pipes are usually arranged so that there are fans to blow air over both the hot part of the pipes and the cold part. The hot part is frequently put outside the house, and the cold part inside. This is called either a 'split pack', or a 'twin pack' depending on which country you are in There are also portable versions which have both parts in the same box, with the cold air blowing out of the front, and the hot air blowing out of a flexible hose which you put put outside the room to allow the hot air to dissipate.
