Summary

The system performance and supervisory control of a direct-fired (natural gas), double-effect, water-lithium bromide absorption chiller was investigated using simulations. A mechanistic model of the chiller was developed and calibrated using manufacturers catalog design data. A computationally-simple model was then derived and coded for use with the programme TRNSYS to simulate the steady-state performance of the chiller, a chilled and cooling water pump, a cooling tower, and a cooling water bypass valve. The optimal supervisory control of the absorption chiller system was determined for different control options.
