| Summary: | 碩士 === 國立臺北科技大學 === 能源與冷凍空調工程系碩士班 === 100 === Centrifugal chiller is the single largest Power consumptions in central HVAC system, Beside the chiller energy efficiency operation at 100% load, But make sure chiller operator at high efficiency at 50-60% part load of a chiller is critical to energy saving for a building performance . According the ARI standard 550/590-98 Integrated part Load Value. Non-standard Part-load Value (NPLV).Most of the Chillers operation 99% at part load condition , for the Multi-chillers plant room and all year chillers operation project required, VFD Chiller have huge advantage for the energy saving. VFD chiller consider as the best solution for the energy saving proposal.
This paper will use computer software to simulation variable frequency drive( VFD) and constant speed drive (CSD) chiller system design and energy consumption in Taiwan climate. The Coefficient of Performance (COP) and payback of a variable frequency drive (VFD) centrifugal chiller with constant speed drive (CSD) chiller.
Also establish base line operating conditions base on ESCO ASHRAE-G14-2002- chiller M&V menth-R-1.01-option B here in Taiwan, To establish base line CSD chiller performance data and base line data of VFD chiller after switch to VFD chiller for the project case to cross- reference with ARI computer simulation data. Analyzed results show that VFD chiller the capacity and performance can improve.
