Calculating the amperage of a 36000 BTU air conditioner allows HVAC technicians to monitor the performance of the installed system and informs the user about the energy consumption of the equipment. This is useful for evaluating purchase options or estimating electricity bills.
The first step is to understand the SEER parameter of the air conditioner, which measures the energy efficiency of the equipment.
Using the SEER parameter, it is possible to estimate the electrical power consumed by the air conditioner.
SEER | 10 | 11 | 12 | 13 | 14 | 15 |
---|---|---|---|---|---|---|
36000 Btu/h | 3600W | 3272.7W | 3000.0W | 2769.2W | 2571.4W | 2400.0W |
SEER | 16 | 17 | 18 | 19 | 20 |
---|---|---|---|---|---|
36000 Btu/h | 2250W | 2117.6W | 2000.0W | 1894.7W | 1800W |
Applying SEER to Determine the Average Consumption of a 24000 BTU/h Air Conditioner
Don’t know the SEER of your equipment?
Use the following table to approximate the SEER value:
Air Conditioner Classification | SEER Value |
---|---|
A+++ | Greater than 22 |
A++ | 20-21 |
A+ | 18-19 |
A | 15-17 |
B – C | Less than 11.5 |
A/C that are not inverter-based | Very low efficiency |
Table 2: SEER Value According to Air Conditioner Classification
For example, for a 36000 BTU/hour air conditioner with a SEER of 15, the expected average consumption is 2400W.
Since SEER is a parameter that measures air conditioner efficiency under various operating conditions (different condensation temperatures), this does not mean the equipment is always consuming 2400W. Over a longer period, where consumption may fluctuate, the average will be close to the calculated value of 2400W.
