臺灣博碩士論文加值系統

屬於亞熱帶國家的台灣，夏季高溫高濕平均氣溫及相對濕度分別約為27.5℃及83%RH，對於需引入外氣維持室內空氣品質之空調場所，室外溫濕度的高低與外氣引入的多寡是影響室內空氣品質及空調負載的一大主因，本研究以實際改善及量測方式分析空調箱外氣需量最佳化控制以及空調箱系統供風區域部份搭配VAV(Variable Air Volume System；VAV)變頻系統其節能效益。在符合室內空氣品質管理法規定與室內空調設定溫度之需求下，以監控電腦自動調整10%~100%空調箱外氣風門開度以及調整30Hz~60Hz風機馬達運轉轉速，藉以改善外氣負荷對空調耗能及非上班時段調整空調送風量降低馬達運轉負載之耗能比較。
此研究以雙種控制模式進行比較，模式一:傳統手動控制外氣風門開度為固定式100%，修改成以偵測室內CO2值與比對室外焓值自動調整外氣風門開度10%~100%之模式。控制模式二、增設部份區域變風量系統及風機馬達加裝變頻器以改善空調箱送風馬達所造成之耗能分析。經由監控電腦記錄室內CO2值、外氣風門開度、外氣焓值與風車馬達運轉頻率之數值，經統計分析後得知春夏秋冬季節變化對建築物空調負荷有直接影響，控制模式一、為單獨改善外氣需量控制之外氣負載耗能其節能率平均為78%，空氣側總節能量達21.2%，主要節能季節為夏季其次是春秋兩季，而控制模式二、為增設外氣需量控制及風機馬達變頻其節能率分別為: 一、外氣需量控制之外氣負載耗能節能率平均為82.1%，二、風機馬達變頻之耗能節能率平均為42.2%，實際總節能量高達51.2%，主要節能為整年度均有節能效果，因此可知改善空調箱外氣需量之控制與搭配VAV變頻控制系統對空調箱系統之節能有很大幫助。

Taiwan belongs to subtropical countries, hot and humid summer mean temperature and relative humidity are about 27.5 ℃ and 83% RH, the need to introduce outdoor air demand conditioned place to maintain indoor air quality, the level of outdoor air introduced into the outdoor temperature and humidity, the amount is a major culprit affect indoor air quality and the air conditioning load .In this study, the actual improvement and measurement mode analysis AHU outdoor air for an optimal amount of control, and air conditioning systems for air box with VAV(Variable Air Volume System；VAV) conversion system area part of its energy efficiency.In line with Indoor Air Quality Management Act and the indoor air conditioning temperature setting of demand, in order to monitor the computer automatically adjust the 10% to 100% of the air box outdoor air throttle opening, and adjust 30HZ ~ 60HZ blower motor operation speed, thereby improving the load of external air conditioning energy consumption and non-working hours to reduce energy consumption and adjust the amount of air conditioning load motor operation comparison.
This study compares dual control modes: Mode 1, a conventional manual control outdoor air damper opening is fixed to 100%, modified to detect indoor than outdoor CO2 value and automatically adjusts the outdoor air enthalpy throttle opening 10% to 100% of the pattern, and the second control mode, an additional part of the zone VAV systems and the installation of the fan motor to improve the energy dissipation of the inverter air conditioner blower motor caused by the box.Via monitor computer records indoor CO2 value, value outdoor air damper opening, the outdoor air enthalpy with windmill operation frequency of the motor, After statistical analysis showed that the seasons have a direct impact on the seasonal variation of the building air conditioning load, a control mode for individual improvement than the outdoor air demand control gas load consumption energy saving rate of 78% of airside its total energy saving amounted to 21.2%, mainly saving for the summer season followed by spring and autumn, while the second control mode for an additional external gas demand control and the blower motor variable frequency energy saving rates were as follows: First, the outdoor air demand control gas load energy saving 82.1% in the second, energy saving fan motor frequency of 42.2%, the actual total energy savings of up to 51.2%,mainly energy-saving effect for the whole year are thus seen to improved control of the air box outside air demand of the inverter control system with VAV air-conditioning system of the box saving a great help.
