Textbook Problem

A freezer has a coefficient of performance of 6.30. The freezer is advertised as using 457 kW-h/y. (a) On average, how much energy does the freezer use in a single day? (b) On average, how much thermal energy is removed from the freezer each day? (c) What maximum mass of water at 20.0°C could the freezer freeze in a single day? Note: One kilowatt-hour (kW-h) is an amount of energy equal to operating a 1-kW appliance for one hour.

(a)

To determine
The energy used by the freezer in a single day.

Explanation

Given Info:

The usage of freezer is 457kWh/y .

Formula to calculate the energy used by the freezer,

W=PΔt

Substitute 457kWh/y for P and 1d for Δt to find the energy used by the freezer,

W=(457kWh/y)(1d)(3

(b)

To determine
The thermal energy removed from the freezer each day.

(c)

To determine
the maximum mass of water at 20°C that the freezer can freeze in a day.
