Short Answer

Estimate the maximum possible COP of a household air conditioner. Use any reasonable values for the reservoir temperatures.

COP=21

Step 1: Given

Assume temp inside room T_c=25^o C = 298 K

Assume temp outside room T_h=40^o C = 313K

Find COP.

Step 2: Explanation

Coefficient of performance (COP) $= \frac{T_{c}}{T_{h} - T_{c}}$
Substitute the values of temperature $COP = \frac{T_{c}}{T_{h} - T_{c}} = \frac{313 K}{(313 K) - (298 K)} = 20.866$ = 21 ( rounded)

Under many conditions, the rate at which heat enters an air conditioned building on a hot summer day is proportional to the difference in temperature between inside and outside, $T_{h} - T_{c}$ . (If the heat enters entirely by conduction, this statement will certainly be true. Radiation from direct sunlight would be an exception.) Show that, under these conditions, the cost of air conditioning should be roughly proportional to the square of the temperature difference. Discuss the implications, giving a numerical example.

Why must you put an air conditioner in the window of a building, rather than in the middle of a room?

Explain why a rectangular $P V$ cycle, as considered in Problems $1.34$ and $4.1$ , cannot be used (in reverse) for refrigeration.

In table 4.1, why does the entropy of water increase with increasing temperature, while the entropy of steam decreases with increasing temperature?

Calculate the efficiency of a Rankine cycle that is modified from the parameters used in the text in each of the following three ways (one at a time), and comment briefly on the results: (a) reduce the maximum temperature to $500 ° C$ ; (b)reduce the maximum pressure to 100 bars; (c)reduce the minimum temperature to $10 ° C$ .
