You're confuseing power consumed with cooling power delievered. Just because work/time and heat/time have the same units does not mean they are interchangeable. Thus you cannot calculate cooling power by measureing power consumed. They're completely different things.

Heres a site explaining how the second law of thermodynamics works:

6 220 watt pelters would equal almost 5000btu consuming 1320watts
