How SEER Rating is Calculated

The SEER rating of an air conditioning unit is calculated by dividing the cooling output in British thermal units (BTUs) by the electrical energy input in watt-hours over a specific period of time. This specific time period is known as a “cooling season,” which is typically defined as a full year or a specific number of months, depending on regional climate conditions.

During the testing process, the air conditioning unit is operated under controlled conditions to measure its energy consumption and cooling output. The test conditions include a set indoor temperature and humidity level, as well as a defined outdoor temperature. These conditions allow for consistent and comparable measurements across different units.

The cooling output is determined by measuring the amount of heat removed from an indoor test space and converting it into BTUs. This is accomplished by monitoring the temperature difference between the indoor air and the room temperature and factoring in the size of the test space.

The electrical energy input is measured using specialized equipment that records the power consumption of the unit in watt-hours. This includes the energy consumed by the compressor, fan motors, and other electrical components during the cooling process.

The cooling output and electrical energy input values are then divided to calculate the SEER rating. For example, if an air conditioner produces 14,000 BTUs of cooling output and consumes 1,000 watt-hours of electricity during a cooling season, the SEER rating would be calculated as 14,000 BTU / 1,000 watt-hours = 14 SEER.

It is important to note that SEER ratings are rounded to the nearest whole number for simplicity and ease of understanding. However, the actual calculations involve more precise measurements and may include additional factors such as part-load performance and standby power consumption.

By using a standardized testing procedure, manufacturers can consistently calculate and label the SEER ratings of their air conditioning units. This allows consumers to compare the energy efficiency of different models and make informed choices based on their specific needs and budget.
