I need some help with conceptualizing the problem. Here there is a refrigeration cycle, I assume that the water is the low reservoir and the air is the high reservoir. To calculate the heat transfer from the water (Q_L) we also need to consider the heat transfer from the surroundings to the water reservoir. So then our Q_L becomes (Q_L = Q_cooling + Q_transfer). This is correct way to think about the problem? **Problem Statement:**The drinking water needs of a production facility with 20 employees are to be met by a bubbler type water fountain. The refrigerated water fountain is to cool water from 22°C to 8°C and supply cold water at a rate of 0.4 L per hour per person. Heat is transferred to the reservoir from the surroundings at 25°C at a rate of 45 W. If the COP (Coefficient of Performance) of the refrigeration system is 2.9, determine the size of the compressor, in W, that will be suitable for the refrigeration system of this water cooler.
