The drinking water needs in a production facility with 20 employees is to be met by a water bubbler type water fountain. The system is to cool water from 22C to 8C and supply cold water at a rate of .4L per hour per person. The reservoir is not isolated and an additional heat load at a rate of 45 W coming from the surrounding air is to be considered on the refrigeration system. If the COP of the refrigeration system is 2.9, determine the size of the compressor, in Watts, that will be suitable to satisfy the cold-water needs in the production facility.

##### Solution Summary

This solutions helps Determine Compressor Size in Watts that is suitable to satisfy certain specific needs.

##### Solution Preview

First determine the heat load from the water supply:
Q=mcdeltaT
where m is the mass flowrate of water (kg/s) = 20*0.4/3600 = 2.22E-3 ...
