Homework Statement
If a room is at 27C and the surroundings at 42C, and the heat into the room is 2,000 Cal s-1. What is the minimum work the air conditioner must do to keep the room at 27C?
Homework Equations
COP = Tc/(Th-Tc)
Win = Qout/(1+COP)
The Attempt at a Solution
COP = (300.15/(315.15-300.15)
COP = 20.01
Win = 2,000 Cal s-1/(1+20.11)
W=95.15 Cal s-1 or 398.1 J s-1
Look okay?
