Impacts of Water Loop Management on Simultaneous Heating and Cooling in Coupled Control Air Handling Units

摘要

The impacts of the water loop managementon the heating and cooling energy consumptionare investigated by using model simulation. Thesimulation results show that the total thermalenergy consumption can be increased by 24%for a typical AHU in San Antonio, Texas whenthe differential pressure is increased from 7 psito 21 psi for both chilled water and hot waterloops. It appears that significant amounts ofenergy consumption can be reduced byimproving the differential pressure of waterloops. This paper presents the system model,methods, and the results.
