Signature of TA to Verify Attendance:
1. What devices in an absorption refrigeration system replace the compressor of a conventional vapor/compression refrigeration system?
2. Describe the four (4) fluid streams within a Trane absorption unit.
3. How does a cooling tower operate?
4. What is the rated capacity of the chilled water plant in tons of refrigeration, Btu/hr, and kW?
5. Given the chilled water flow rate (from the pump) and the entering and exiting temperatures of the chilled water stream for one of the absorption units, calculate the actual cooling load (in tons of refrigeration) the unit is providing.
6. Determine the Carnot cycle COP for the absorption cycle used at the MSU chilled water plant.
7. Using the Carnot cycle COP and assuming a cooling load of 1250 tons, determine the required mass flow rate of steam.
