Problem Statement: You are asked to design an optimum refrigeration system for a warehouse with both freezing and refrigerated spaces. Design constraints are as follows: Working fluid: R-134a Freezer temperature range: -24 ˚C < T freezer < - 18 ˚C Refrigerator temperature range: 3 ˚C < T refrigerator < 7 ˚C Ambient temperature: To = 25 ˚C Compressor efficiency: 80% Heat exchanger temperature difference: ΔT = 10 ˚C Freezer Cooling load: QF = 30 Tons of refrigeration Refrigerator Cooling load: QR = 20 Tons of refrigeration You should at least compare three different systems So I need for you to make only one system
