Efficiency Measures
|
Seasonal Energy Efficiency Rating (SEER):
|
10.2
|
|
SEER is the most commonly used measure of a residential central air
conditioner's efficiency. The SEER is the ratio of cooling capacity of
the unit relative to the amount of electricity input, normalized for the
changing demands over the cooling season. Thus, the higher the value of
the SEER the more efficient the unit. (The most efficient air conditioner
that we know of has a SEER of 21.) As of January 2006, new air conditioners must have a SEER of at least
13 to be sold in the United States.
If you are purchasing a residential furnace, you should compare air conditioners
efficiencies using the SEER.
|
Inputs to Calculate the SEER:
|
|
- SEER Cooling Capacity: 8.9 BTUH
- SEER Electrical Input: 0.76 watt-hours
- Degradation Coefficient: 0.25
|
Energy Efficiency Rating (EER):
|
10.1
|
|
The EER is the most commonly used measure of air conditioner efficiency
for non-residential central air conditioners. Although the SEER
gives a more accurate estimate of the seasonal efficiency of the unit,
SEER is not typically calculated for non-residential units.
The SEER is the simple ratio of the cooling capacity (in BTUH) to the
electrical input (in watt-hours). It is therefore a steady-state
measure, meaning that it does not take into account the inefficiencies
that generally occur during startup and shutdown, when the unit is not
operating at full capacity.
|
Integrated Part Load Value (IPLV):
|
Not Available
|
|
The IPLV measures the efficiency of air conditioners under partial
load.
|
Coil Model Number:
|
MS09NW
|
|
The condenser coil is one of the highest energy consuming components of an air conditioning system. Thus, selecting a highly efficient central air conditioner often requires that the model have an efficient model of condenser coil.
You probably do not need to worry about the particular model of condenser coil when you purchase a central air conditioner -- instead, pay attention to the efficiency measures such as SEER and EER. We include coil model numbers because you may need them when repairing a central air conditioner and/or applying for a central air conditioner rebate.

Capacity Measures
|
Cooling Capacity:
|
8,500 BTUs / hour
|
|
The number of BTUs per hour of heat that the unit
is capable of removing from the air when running at a steady state.
(That is, when it
has finished startup and is running at full power.)
A BTU (British Thermal Unit) is the quantity of heat required to raise
1 pound of water by 1 degree Fahrenheit.
|
Electrical Input:
|
841 watts per hour
|
|
The electrical input in watts required to operate the air conditioner for
an hour at its full cooling capacity.
A single watt is equal to 1/746 horsepower.
