Just a quick question. Is there a formula for the coefficient of performance equation for just temperatures. All I have is the outdoor and indoor temperauture. How would I approach that?
Yes, there is such a formula. It generally assumes that the heat pump (or refrigerator) is an ideal Carnot engine (maximum efficiency -- no losses due to friction, etc.)Just a quick question.

Do you already have formulas for COP as a function of Q_{hot} and Q_{cold}?what is Q? how would i find that.
because in my problem, i literally only have Tc and Th. how do i do that?
The coefficient of performance or COP of a heat pump is the ratio of the change in heat at the "output" (the heat reservoir of interest) to the supplied work.when it asks for joules of heat, what specifically is this asking me to solve for?
You absolutely have to convert to Kevlin!and if i use the equation you wrote above, do i have to convert it to kelvin or can i leave it as celcius?
