(a) Describe the terms "Refrigeration" and "Air-conditioning". Determine the units of Refrigeration ?
(b) The capacity of refrigeration is 400 TR when working between -6oC and 25oC. Evaluate the mass of ice produced per day from water at 25oC. Also determine the power required to drive the unit. Consider that cycle operates on reversed carnot cycle and latent heat of ice is 335 KJ/Kg.
