Question

Hello, please help with this question for review purposes cuz my prof didn't teach us anything. Please provide charts and Table used with Plotting.

3. A reverse carnot refrigeration used to produce ice at 0°C, water is available at 301 K, brine mixture is = 16°c, find the coefficient of performance. 4. A refrigeration system using refrigerant 22 is to have a refrigerating capacity of 80 kW. The cycle is a standard vapor – compression cycle in which the evaporating temperature is – 8° C and the condensing temperature is 42°c. a) Determine the volume flow of refrigerant measured in cubic meters per second at the inlet to the compressor. b) Calculate the power required by the compressor. c) At the entrance of the evaporator what is the fraction of vapor in the mixture expressed both on a mass basis and a volume basis?
