How many units will a new 1.5 ton A.C. consume per hour?

Will the power consumption keeps increasing with every 1 deg. C. reduction in th a.c.?

Units of electrical power?





It depends on how often it runs. AC's have a thermostat, the dial you set for temperature. It turns the AC on and off to keep the temperature at your setting.





How much time it spends on vs off depends on outside temperature, size of room, insulation, number of windows and doors, etc.





1.5 ton translates to 5.3 kWatts of power. This is what the AC will use if it is operating all the time. If it is on only 50% of the time (more likely) then it will use about 2.6 kWatts of power.





2.6 kWatts of power for 24 hours is 63 KW-hrs of energy used.


At about 6 cents per kW-hr, this comes to about $4 cost of electricity. Check your power bill for costs in your area.








The second half of your question is confusing. By 1 degree reduction in the AC do you mean 1 degree reduction in the thermostat setting?





Yes, power consumption will go up every degree you reduce the temperature setting, because the percent time the unit stays on will increase. In the example above, the "duty cycle" may change from 50% to 52%.
Reply:400 watts per hour


but dont know about units.
