A refrigerator using a 0.5 hp motor has a coefficient of performance of 3.05. 2 gallons of tea (model as water) is placed into the refrigerator at 80oF. How long will it take for the refrigerator to cool the tea to 40oF, assuming that this is the only heat load to be considered. Does this seem realistic? If not, what assumptions were made which make the calculation appear unrealistic?
Given: ?= 3.05; W?= -0.5 hp = 0.3534 Btu/s; Water: V= 2 gal = 0.2674 ft3; T1 = 80oF; T2 = 40oF Assume: The refrigerator is operating in a cyclic fashion. The water behaves as an incompressible substance with constant specific heats: c = 1 Btu/lbm-RSolution: What will be an ideal response?
