Question
Thermodynamics II
2.)
Fill-in the blank. Thank you for your help. Much appreciated.
In a redesign of a refrigerator, the fan noise could be reduced by decreasing the airflow over the evaporator, so that the new evaporator would be .......... (bigger/smaller). With the new evaporator size, space for frozen goods in the freezer section would ........... (increase/decrease) and the cycle design would require a .............. (smaller/larger) temperature difference at the evaporator. The change in temperature difference across the evaporator would result in an ................ (increased/decrease) power input at the compressor for the same heat load. The COP would ............... (increase/decrease/stay the same).
Thank you for your help. It is very much appreciated.
Explanation / Answer
New evaporator size will be smaller so that space for frozen goods decreases and temperature difference will be smaller would result decreases in power output and increase in cop
