[quote=Anonymous][quote=Anonymous][quote=Anonymous] Stop using air conditioning You are the problem [/quote] Air conditioning is actually more efficient than heating, and generally requires smaller thermal gradients (90 to 70 vs 22 to 70). https://iopscience.iop.org/article/10.1088/1748-9326/8/1/014050 [/quote] If a heat pump is used for both AC and heating, wouldn't the efficiency be the same? Suppose the outdoor temperature is 50F and we wish to warm the indoors to 70F. This is a 20-degree temperature differential. I would think this would require the same amount of energy as if the outdoor temperature were 90F and we wished to cool the indoors to 70F, assuming that a heat pump is used for both heating and cooling.[/quote]
