SOLVED: A refrigerator with R-134a as the working fluid operates between the pressure limits of 320 and 1200 kPa. If the rate of heat removal from the refrigerated space is 35 kJ/s, find the values of h1 and h3. [ANS: 251.93 kJ/kg, 117.79 kJ/kg]Calculate the mass flow rate of the refrigerant. [ANS: 0.261 kg/s]The equations to analyze the Ideal Vapour-Compression Refrigeration Cycle are shown below:Win = h2 - h1QH = h2 - h3QL = h1 - h4where h1 = hg@P1 and h3 = hf@P3
