A study on evaluation systems for optimized design GSHP and ES technologies used in HVAC systems

Abstract Due to the lack of suitable evaluation systems for heating, ventilation, air-conditioning (HVAC) with ground source heat pump (GSHP) and energy storage (ES) technologies, it is difficult design a building HVAC system achieve optimized regard investment cost, saving environmental protection. This study on developing fuzzy by including GSHP ES comprehensively determined weights into an system. A questionnaire method was used answers from 21 experts were analyzed facilitate modeling. Taking commercial integrated project in Nanjing as engineering case, tested. If comprehensive merit value 0.303 adopted, annual operating cost reduced 32.5%, total life cycle 26.5% primary consumption carbon emissions are 10.5%, initial increased 6.5%. revealed that newly developed very useful realizing optimal systems.
