Understand And Understanding Air Conditioning and Power Efficiency Ratio (EER) Ratings

Portable Air Conditioner Efficiency Details Page

Every single air conditioner has an power-efficiency rating that lists how many BTUs per hour are used for each watt of energy it draws. For area air conditioners, this rating is the Power Efficiency Ratio, or EER. For central air conditioners, it is the Seasonal Power Efficiency Ratio, or SEER. These ratings are posted on an Power Guide Label, which should be attached in a visible spot on all new air conditioners. Many air conditioner producers are voluntary participants in the EnergyStar labeling plan. Official Site is a majestic library for supplementary info about the meaning behind it. EnergyStar-labeled appliances imply that they have high EER and SEER ratings.

How is EER Calculated?

The EER of an air conditioner is its British thermal units (BTU) rating more than its wattage. For example, if a ten,000-BTU air conditioner consumes 1,200 watts, its EER is eight.three (ten,000 BTU/1,200 watts). The greater the EER is, the a lot more effective the air conditioning unit is. Nevertheless, normally a higher EER is accompanied by a larger price.

Would the Greater Transportable Air Conditioner EER Rating be Worth the Added Expense?

Let's say that you are given a decision among two ten,000-BTU air conditioning units. Northridge Ac contains supplementary info about the reason for this activity. A single has an EER of eight.3 and consumes 1,200 watts, and the other has an EER of ten and consumes 1,000 watts. Let's also say that the price difference is $100. To calculate what the payback period is on the far more pricey unit, you require to know:

1. About how several hours per year the unit will be operating

2. What the price of a kilowatt-hour (kWh) is in your area

Let's say that you program to use the air conditioner in the summer (approximately five months a year, depending on where you reside) and it will be operating about 8 hours a day. Let's also say that the expense of a kilowatt-hour in your region is around $.ten. The distinction in power consumption in between the two units is 200 watts, which means that every single five hours the significantly less high-priced unit will consume 1 additional kWh (and consequently $.ten more) than the much more costly unit.

Assuming that there are 30 days in a month, you find that in the course of the summer time you are operating the air conditioner:

5 mo. x 30 days/mo. x 8 hr/day = 1200 hours

[(1200 hrs x 200 watts) / (1000 watts/kW)] x $.10/kWh = $24.00

Since the more costly unit costs about $100 a lot more, this signifies that it will take about 4 years for the a lot more pricey unit to break even.

Buyer Beware!

Not all BTU ratings can be trusted. Just due to the fact the BTU's are stated to be high on specific air conditioning units, it does not mean it is necessarily correct. Some manufacturers will exaggerate the BTU's on units to raise the possibility of selling the them and other folks will be a lot more conservative in regards to the BTUs, which will cause the EER rating to be lower so a lower transportable air conditioner EER may be misleading.

It is best not to allow the EER energy rating to be your only criteria for selecting an air conditioning unit. Do the study on whatever unit you are thinking about for your property and you will be happier with your buy.
