Reducing Service Contract Costs and Do-lt-Yourself EM Maintenance

Reducing Operating Costs with Optimal Maintenance Scheduling

The potential benefits of optimal service scheduling for cleaning heat exchangers based on minimizing operating costs are explored. A demonstration is performed on a simulated 20 ton air-to-air vapor compression air conditioner. The costs of regular service schedules (indicative of current practice), minimal schedules needed to maintain comfort, and the optimal schedules are compared. Generally...
