中央空調系統之最佳化卸載控制

本論文建構一套『負載管理系統』，達到即時遠端能源監控及降載等功能，並透過網際網路傳送電錶數據及卸載指令達到雙向溝通，因此本論文提出一套最佳化的中央空調系統降載策略，基於冰水主機與冷卻水塔對於冷凝器入水溫的影響，透過線性規劃演算法求出目標最低耗電量下之冰水主機耗電量以及冷卻水塔耗電量以及最佳化冷凝器入水溫度，並且依據外氣濕球溫度模擬計算整體中央空調系統整年之負載量，並配合微型電網緊急電力調度之降載措施達到雙向監控及下達卸載命令，此控制器具有RS-232及RS-485通訊埠，本實驗通訊方式採工業常用的Modbus通訊協定並透過RS-485傳輸資料，並將回傳於控制器的資料透過網際網路傳送至控制中心，控制中心內部撰寫人機介面接收負載資訊以及下達卸載命令，將負載資訊匯入SQL資料庫中，並以Asp.net撰寫能源監控網頁以便管理人員監看需量降載的效益。

This thesis constructed a set of "load management system" to achieve real-time remote energy monitoring and load shedding functions, and send over meter data and uninstall instruction through to achieve two-way communication, In order to achieve bi-directional control and the unload command, this thesis presents a set of best central air-conditioning system of load shedding strategy, basing on consumption and cooling tower consumption that are under effects of temperature. To calculate the chiller power consumption and cooling tower consumption that are under the target lowest power consumption and optimal water temperature, and based on outside air wet bulb temperature to calculate the simulation of central air-conditioning system load throughout whole year with emergency power micro-grid schedule of load shedding measures. This industrial controller has RS-232 and RS-485 communication port at experimental. Communication which is adopted in this experiment is the Modbus protocol commonly used in industry and transfer data through the RS-485 and returned the controller data via the Internet to the network control center, control center receives the internal load information to write human-machine interface to issue the uninstall command and load information into a SQL database, meanwhile to write the energy monitoring with Asp.net so that managers can monitor the amount of drop set of benefits.
