Variable flow and optimization of chiller loading effect on energy saving for screw vapor compression-single effect absorption hybrid chiller plant in hospital mechanical room ‒ case study: Tehran heart hospital

Chiller plants are the most energy consuming system during summer season in residential, commercial and hospital buildings. The highly variable cooling demand of buildings connected to a hybrid chiller plant included absorption vapor compression chillers achieve higher efficiencies is one important issues. Cooling load sharing strategies apply water flow have significant impact on consumption consequently with more productivity environmentally protected. This paper examines behavior pattern that includes combination two air-cooled screw three single effect chillers. In order properly understand consumption, an existing mechanical room Tehran has been studied for five months, its compared optimized model. results indicate sequence function way which they placed circuit partial load, highest importance view point saving also by Applying loading achieved plant.
