The drinking water needs of a residential hall with 20 students is to be met by a bubbler type water fountain. The refrigerated water fountain is to cool water from 22 to 8oC and supply cold water at a rate of 0.4 L per hour per person. Heat istransferred to the water reservoir from the surrounding (kitchen air) at 25oC at a rate of 45W. a) If the COP of the attached refrigeration is 2.9, determine the size of the compressor, in W, that will be suitable for the refrigeration system of this water cooler. b) Now, assume that the refrigeration system is ideal (all reversible processes) and operates between TL =0oC and TH =35oC . Calculate COP value of the reversible refrigeration system and determine the new size of the compressor, in W, that will be suitable for the reversible refrigeration system of this water cooler.
