18000 BTU Power Consumption

Calculating how much an 18,000 BTU air conditioner consumes is essential for air conditioning specialists to assess the performance of the installed system. Additionally, the amperage information helps users understand the energy consumption of the equipment, whether to evaluate purchase options or verify electricity bills.

How many watts does a 18000 btu air conditioner use?

The consumption of an air conditioner depends on various factors, including the efficiency of the air conditioner, the thermal load inside the space, the outdoor temperature, and the time that has passed since the equipment was turned on for the first time.

To start, it’s important to know the SEER (Seasonal Energy Efficiency Ratio) parameter of the air conditioning unit, as it measures the equipment’s performance. With the SEER parameter, you can estimate the average electrical power consumed by the air conditioner in watts (W). Note that for non-inverter air conditioners, a SEER value of less than 12 is considered inefficient.

Here’s a table showing the average electrical power consumption based on SEER for a 18000 BTU/h air conditioner:

SEER	Average Power (W)
10	1800
11	1636.4
12	1500
13	1384.6
14	1285.7
15	1200
16	1125
17	1058.8
18	1000
19	947.4
20	900

How much electricity does a 18,000 btu air conditioner use per hour?

To find the amperage consumption, you can use the power consumption value from the previous table and refer to the following tables based on the type of supply voltage. Here are some sample values:

How many amps does a 18000 btu air conditioner use?

For a single-phase power supply (PH1):

Power (W)	110 V	115 V	120 V	127 V	220 V	230 V	240 V
900	11.36 A	10.87 A	10.42 A	9.84 A	5.68 A	5.43 A	5.21 A
950	11.99 A	11.47 A	11.00 A	10.39 A	6.00 A	5.74 A	5.50 A
1000	12.63 A	12.08 A	11.57 A	10.94 A	6.31 A	6.04 A	5.79 A

For a three-phase power supply (PH3):

Power (W)	220 V	230 V	240 V	380 V	400 V	440 V
900	3.28 A	3.14 A	3.01 A	1.90 A	1.81 A	1.64 A
950	3.47 A	3.32 A	3.18 A	2.01 A	1.91 A	1.73 A
1000	3.65 A	3.49 A	3.35 A	2.11 A	2.01 A	1.82 A

How much power does a 18000 btu air conditioner use?

For example, for an 18,000 BTU/h air conditioner with a SEER of 12, you can expect an average power consumption of 1,500 watts and an average current consumption of approximately 9.47 amperes.

Understanding the amperage and power consumption of your air conditioner can help you make informed decisions about its usage and energy costs.
