Learn And Understanding Ac and Power Performance Ratio (EER) Reviews
Portable Ac Efficiency Data Site
Each air conditioning equipment posseses an energy-efficiency ranking that lists how many BTUs per hour are employed for each watt of power it brings. If you are interested in jewelry, you will probably wish to research about energy news. For room air-conditioners, this rating is the Energy Efficiency Ratio, or EER. For central air conditioners, it is the Seasonal Energy Efficiency Ratio, or SEER. These ratings are placed on an Energy Guide Label, which has to be attached in a position on all-new air conditioners. Several air conditioner companies are voluntary participants within the Energy-star labeling program. EnergyStar-labeled appliances mean that they have large EER and SEER reviews.

How is EER Assessed?
The EER of an air-conditioner is its British thermal units (BTU) score over its electricity. Like, in case a 10,000-BTU air conditioner uses 1,200 watts, its EER is 8.3 (10,000 BTU/1,200 watts). The bigger the EER is, the more efficient the air con unit is. Nevertheless, usually a higher EER is accompanied by a higher price.
Could the Higher Lightweight Air-conditioner EER Status be Worth the Additional Cost?
Let's say that you are given a choice between two 10,000-BTU air-conditioning units. One consumes 1,200 watts and has an EER of 8.3, and the other has an EER of 10 and consumes 1,000 watts. Let us also say that the price big difference is $100. To estimate exactly what the payback period is on-the higher priced system, you have to know:
1. About how many hours each year the unit is going to be operating
2. What the price of the kilowatt-hour (kWh) is locally
Let us say that you plan to make use of the air conditioner in the summer (around five weeks a year, depending on where you live) and it will be running about 8 hours a day. Let us also say the cost-of a kilowatt-hour in your area is approximately $0.10. The difference in power consumption between both devices is 200 n, meaning that every five hours the less expensive unit will digest 1 additional kWh (and thus $0.10 more) compared to more expensive unit.
Assuming that there are 30 days in a month, you find that during the summer you are operating the air conditioner:
5 mo. Be taught more on the affiliated article directory - Click here: division. x 30 days/mo. x 8 hr/day = 1200 hours
[( 1200 hrs x 200 n) / (1000 watts/kW )] x $0.10/kWh = $24.00
Because the more expensive unit costs approximately $100 more, which means it'll take about four years for the more expensive unit to break-even.
Consumer Beware!
Not all BTU ratings can be trusted. Just because the BTU's are stated to be high on specific air-conditioning units, it doesn't mean it is necessarily true. Some manufacturers will exaggerate the BTU's on products to raise the possibility of attempting to sell the them and the others will be more conservative when it comes to the BTUs, which will cause the EER score to be lower so a lower portable air-conditioner EER may be misleading. It's best not to permit the EER energy rating to be your only criteria for choosing an air con unit. Do the research on what-ever product you are considering for your home and you will be happier with your purchase.
