COOLING COST MINIMIZATION USING BUILDING MASS FOR THERMAL STORAGE.

Author(s) : SNYDER M. E., NEWELL T. A.

Summary

A MODEL HAS BEEN DEVELOPED TO DETERMINE THE LEAST-COST COOLING STRATEGY FOR A BUILDING BY USING THE BUILDING MASS FOR THERMAL STORAGE. THE SAVING IS ACHIEVED BY SUBCOOLING THE MASS IMMEDIATELY BEFORE THE PEAK UTILITY RATE PERIOD, THEREBY SHIFTING A PORTION OF THE COOLING LOAD OFF-PEAK. THE METHOD FORMULATES AN OBJECTIVE FUNCTION BASED ON THE ENERGY CONSUMPTION OF A SIMPLE BUILDING MODEL. DAILY ENERGY USE IS BROKEN UP INTO 3 PHASES: COAST-UP, MAINTENANCE, AND SUBCOOLING, WHICH ARE MULTIPLIED BY AN APPROPRIATE ENERGY COST TO FIND THE TOTAL DAILY COOLING COST. THE COOLING COST IS THEN OPTIMIZED WITH RESPECT TO AN APPROPRIATE INDEPENDENT VARIABLE.
