Calculating the CoP of my fridge ThermalPerformance

I have a project in my thermo class that requires me to calculate the Beta and Beta_Max of my own fridge.

It seems simple enough but the professor keeps saying this will be the hardest thing you ever do.

All I need to do is find the heat transfer Q_C and the work in (Just the power it uses correct?).

Beta = Q_c/ W_in

Beta max is just the T_c = temperature of the cold environment and T_h= temperature of the hot environment.

Beta_max = T_c/ (T_h - T_c)

What I know about my fridge: 110-127 VAC @ 11.6 Amps Uses R-134A Charge 5.0 Oz

My questions are:

1. Where can I start on finding Q_c?


2. T_c would be my temperature of my freezer or refrigerator and T_h is the ambient room temperature?
