Chapter 9, Problem 9.22P

Interpretation Introduction

Interpretation:

What is the allowable rate of heat loss (kW) from the kitchen to the outdoors for the engineer’s proposal to make sense..

Concept Introduction:.

The heat rejected from the refrigerator is calculated by the following formula,

  $Q_H=W_S+\left|Q_C\right|$.

Where$W_S$is calculated from the coefficient of performance of the refrigerator calculated by using Carnot refrigeration’scoefficient of performance..

The coefficient of performance of the Carnot refrigeration cycle is calculated as,

  ${\omega }_{carnot}=\frac{T_C}{T_H-T_C}=\frac{Q_C}{W_{carnot}}$.

Where$Q_C$ is the heat supply to the refrigerator.
