摘要: Abstract The whole chains of exergy flows for different cooling systems were compared. effects demand (internal vs. external solar shading), space method (floor air with ventilation system), and the availability a nearby natural heat sink (intake system being outdoor from crawl-space, air-to-water pump ground exchanger as source) on performance investigated. It is crucial to minimize because it possible use wide range sinks (ground, lake, sea-water, etc.) indoor terminal units, only minimized demand. water-based floor performed better than air-based system; when an was used source, required input 28% smaller system. auxiliary significantly larger systems. available cool in crawl-space resulted 54% 29% power plant systems, respectively. For cooling, can be reduced by 90% 93%, ground, A new approach efficiency introduced prove that supply matches well low
