Question:

Geothermal liquid water from a well is available at 210oF at a rate of 86,000 lbm/h and is to be used for space cooling using an absorption refrigeration system. Geothermal water leaves the generator of the absorption system at 180oF. If the COP of the absorption system is 0.70, determine the rate of cooling provided by the system. This geothermal cooling system is replacing a conventional cooling system (vapor-compression refrigeration system) with a COP of 2.3 and the price of electricity is $0.14/kWh. Determine the potential revenue that can be generated by this geothermal cooling system if geothermal cooling is sold with a discount of 20 percent compared to conventional cooling. Use an operating cooling period of 2000 hours at the calculated cooling rate.
