Question

4- A freezing room maintained at -25 oC. Beef of 30 ton at 15 oC to be cooled -25 oC in 16 hr. Thermal properties of Beef are, freezing point is-1.7 oC, latent heat = 231 kJ/kg, specific heat above freezing is 3.43 kJ/(kg. K), and below freezing is 1.72 kJ/(kg. K). Heat transmission, air change and other appliances loads are estimated to be 6 kW. Estimate the cooling load in TR and assuming safety factor of 10 %.
