Wattage, by definition, is a way to measure power, or the amount of power required to operate an electrical appliance or device. Obviously, you would like the EER to be as high as possible, but normally a higher EER is accompanied by a higher price. In practice some is expended as heat outside the building, so the actual COP will be slightly less than 4. In fact, a room air conditioner that's too big for the area it is supposed to cool will perform less efficiently and less effectively than a smaller, properly sized unit. Do The Math It's Simple. Then from equation 16, the COP is 2. The move towards energy efficiency has been trending for both environmental and financial reasons. The bizarre units of measurement originated in the US to measure the efficiency of an air conditioning system in a steady state. Sizing and Selecting a Room Air Conditioner The required cooling capacity for a room air conditioner depends on the size of the room being cooled -- room air conditioners generally have cooling capacities that range from 5, Btu per hour to 14, Btu per hour.
The air conditioner EER is its British thermal units (BTU) rating over its To calculate what the payback period is on the more expensive unit. EER stands for Energy Efficiency Ratio. The EER rating for an air conditioner is calculated by dividing the BTU (British Thermal Units) rating by the wattage.

The higher an air conditioner's SEER or EER rating is then the more energy It is the average over a cooling season, and is calculated using a.
This is a very approximate guide that allows you estimate the size of current clamps that you may need if you want to monitor such a system. Lower BTU units are for smaller rooms. More power is put into the house than used in electricity.
Electric Stoves: Which is really more efficient? The efficiency of air conditioning systems changes with operating conditions.
Room Air Conditioners Department of Energy
With a portable air conditioner you can target that one room or area specifically, cooling it down to a desirable level, while the rest of the home remains the same.
Energy efficiency rating is a big deal when it comes to classifying portable air The EER of an air conditioner is easy to calculate, but there are a few terms and.
It has no place to go. Verify that your home's electrical system can meet the unit's power requirements.
How Air Conditioners Work BTU and EER HowStuffWorks
All of the electricity that is input to the unit is converted to heat. Room Air Conditioners.
The less wattage used, the less energy used. The EER is usually specified under the conditions shown in table 1. However, this helps to explain where the power is used in such a system.
