中文摘要 | 背景:傳統之空調系統大抵皆採用定頻馬達進行設計,於低負載狀態下,常造成效率降低與能源浪費。經了解變冰水量空調系統(Variable Water Volume)乃依負載需求變動而調節運轉供應,而大多皆以中大噸數之空調系統做為應用。過去,由於在整合性部份負載效率(Integrated Part Load Value)之計算,必須憑藉著一段時間的實際運轉獲得數據進行運算,對此議題值得探討研究。目的:建立我國氣候型態下,中央空調系統運轉負載之權重因子(weighting factor),以形成空調系統運轉之IPLV計算架構。方法:本研究以程式軟體建立某一實測運轉負載下,既有VWV空調系統獲得之相關性能參數。且經模擬比對完成實測運轉印證後。進一步地,以預測不同部份負載之空調系統運轉性能;同時,參考與我國氣候型態相近國家之權重因子(weighting factor),進行估算獲得VWV空調系統之IPLV。結果:模擬比對既有VWV空調系統實測運轉參數,獲得極高準確度。可藉此建立的模型,預測不同部份負載之空調系統運轉性能。另一方面,完成建立我國氣候型態下,可適用於中央空調系統運轉之IPLV計算架構,以供參考。結論/實務應用:中央空調系統運轉之IPLV計算式與設置使用所在區域之氣候型態有關,而影響系統負載權重因子。所以,有必要建立本國氣候型態適用之整合性部份負載效率計算架構。提供本研究以VWV空調系統作為模擬與實測印證後之計算基礎。 |
英文摘要 | Background: Conventional air conditioning systems are probably using fixed-frequency motors are designed for low load condition, often results in inefficiencies and waste of energy. Change upon ice-water air-conditioning system is adjusted according to changes in load demand supply operation, and most of all to large tonnage air conditioning system for the application. The past, calculations for Integrated Part Load Value, must obtain data with a period of actual work operations. Therefore, it is worth to discuss this issue. Purposes: In this domestic climate type, we hope to build these weighting factors with the different operational load for HVAC system, as a computational frame of IPLV of HVAC system. Methods: This research program set up some test software running under load, both VWV air-conditioning system access to relevant performance parameters. After the simulation, it was completed and also got the higher reliability. Further, it can predict the different partial load operation performance of air conditioning system. At the same time, we will refer to the weighting factor of climate patterns similar to the State in China, IPLV of the estimates obtained from VWV air-conditioning system. Results: By means of comparing with both of simulation and experimental running data of an existing VWV air-conditioning system, they have gotten very high accuracy. We can use a simulation model to predict different part load operation performance of air conditioning system. On the other hand, a computational frame of IPLV, under native weather patterns, can be completely established and applied in central air-conditioning system operation, as a reference. Conclusions: For a central air-conditioning system operation, its IPLV calculation depends on the district climate patterns of setting location, so as to impact on system load weighting factor. Therefore, it is necessary to establish an applicable computational frame for IPLV with national climate pattern. It will provide the research as a computational basis for being verified simulation and measurement of VWV air-conditioning system. |
