An air-cooled window DX unit is used for space cooling. The unit has a capacity of 4.5 tons and has a SEER of 15. If the unit operates for 2204 hours during the summer, how many kWh of electricity will be used? Hint: In the U.S., the SEER is the ratio of cooling in British thermal units (BTUs) to the electrical energy consumed in watt-hours. You may need to convert the unit in this process.
