An optimal maintenance scheduler.

Author(s) : ROSSI T. M., BRAUN J. E.

Summary

A practical sub-optimal service scheduling technique has been described that estimates the best time to perform maintenance on heating, ventilating, air conditioning and refrigeration equipment to minimize lifetime operating costs. Simulation results on a 70 kilowatt air conditioner in an office building indicate that the method is always within 2% of the optimal solution. For short fouling times, optimal service times are controlled by the comfort constraint. Additional savings are possible by doing more service (than the minimum) for longer fouling times. Issues concerning implementation and the detecting of multiple simultaneous faults are discussed. Laboratory testing is the next step in the development and validation of this technique.
