par mted, you A refrigeration system is to cool bread loaves with an average mass of 390 g from 30°C to -10°C at a rate of 1200 loaves per hour with refrigerated air at -30°C. Take the average specific and latent heats of bread to be 2.93 kJ/kg-°C and 109.3 kJ/kg. Determine the size of the compressor of the refrigeration system, in kW, for a COP of 1.2 for the refrigeration system. The size of the compressor of the refrigeration system is kW.
