Sears has a 5,200 BTU window mount air-conditioner advertised **broken link removed** Scrolling down to "Power and Performance" specification, it says the current draw is 4.5Amps, cooling amperage for 5200 BTU/HR. But the math doesn't work out:
1J = 3600 Watt*Hr
1BTU = 1055J source
so
1BTU = 1055*1J/3600 = .29Watts
And so
5200BTU/HR = 1524Watts. minimum, not considering system efficiency.
But at the specified 4.5Amps, that's only 540Watts. Am I missing something?
