PostSubject: EER And Ac units.   Tue Oct 18, 2011 4:00 pm

When considering what sort of air conditioner to purchase for ones home or for a single room of your abode, you will want to seriously consider the Energy Efficiency Rating (or EER) of the different units. What is this EER that could be so frequently spoken of for air conditioning and refrigerators, you talk to? Such a good thought should be addressed to enable you to make the best possible decision for the next air conditioner.
As stated earlier, EER stands for Energy levels Efficiency Rating. Standardized from the Air-Conditioning and Refrigeration Company, this rating reports central air-con efficiency at 95 degrees Fahrenheit outdoors and sixty degrees F indoors. EER is a measure of how much electricity needed by an hvac to cool a room or house to your desired level of BTU (British Heat Units). Moreover, EER applies primarily to commercial air-con systems and measures the “ steady-state” efficiency of ac units. This means that EER tells the efficiency from the air conditioner once it had been running for some time (due to the news that more energy is required to get the air conditioner started). The rating system is made up a ratio of desired BTU level to wattage usage to cool to that particular level. For example, an ac that can cool 10, 000 BTU using 1000 watts could have an EER of 10. Most of the time, a EER of 10 could be the minimum of new models.
In relation to EER, another rating employed by the Air-Conditioning and Refrigeration Institute stands out as the Seasonal Energy Efficiency Rating (or SEER). SEER is only appropriate to residential or individual cooling units and is often regarded as being a more correct and reliable indicator in the overall energy efficiency than the standard EER. Currently, ac units must have an SEER of more than 13 to be sold inside U. S. Some air conditioning units have an SEER all the way to 21. Though SEER is generally criticized for not considering the air conditioner's capability while under partial place, even though there is very little widely available rating of residential air conditioning equipment efficiency under partial pack.
One rating system that does address the matter of partial load efficiency stands out as the Integrated Part Load Significance (or IPLV). Also produced by the Air-Conditioning and Refrigeration Institute, IPLV measures partial pack efficiency only in commercial cooling units. Contrary into the EER, which measures commercial ac units at their “ steady-rate”, IPLV measures commercial air conditioner efficiency in many different conditions – namely, with 25%, 50%, 75%, and also 100% capacity and located at different temperatures.
Another rating to take into consideration is the “ fleet efficiency” or “ ac rating”. The fleet efficiency procedures the aggregate efficiency of most cooling systems built by just a particular brand. The fleet efficiency tells nothing in regards to the air conditioner quality or the durability from the certain brand's air conditioners, but it will provide you with an idea of how much you'll cough up you to run an air conditioner of different air conditioners. As it only measures efficiency, it won't necessarily indicate that a special model from one brand of air conditioner outperforms any other model of air conditioner built by way of a different company.
When purchasing an ac, whether it is the commercial, residential, or portable ac, be sure to brows through the yellow tags that are essential by federal law to be displayed by the brand name. These tags show the EER within the air conditioner along with an estimated annual operating cost for that given unit. Probably some of the most convenient element of that yellow EnergyGuide tag is often a sliding scale which helps you compare different units comfortably as its EER is plainly displayed on the scale from 10 to help you 16. 9. Consult with a qualified air conditioner technician to look for the correct capacity that you need to cool the desired community. Also, look at many different models and brands of air conditioners to be sure you find the best possible unit for you.
