摘要:隨著我國經(jīng)濟的高速發(fā)展，微電子技術，計算機技術，自動化控制技術都得到了迅速發(fā)展，交流變頻調(diào)速技術也已經(jīng)進入了一個嶄新的時代，其應用越來越光。而風機作為礦山企業(yè)必不可少的設備與企業(yè)的生產(chǎn)效率緊密相關，隨著能源的日益緊缺，企業(yè)中的設備節(jié)能問題就顯得尤為重要。 本文將以一個商務酒店風機系統(tǒng)節(jié)能的實例來對此風機系統(tǒng)展開描述。此風機系統(tǒng)由冷凍、冷卻泵電機組成。主機可以根據(jù)載量變化增加和減少，冷凍和冷卻系統(tǒng)卻不能隨負載變化作出相應的反應，故存在很大的鋪張。本次設計結合后臺風機系統(tǒng)的工作，利用電機、PLC、數(shù)據(jù)轉換模塊、溫度感應等組成溫差閉環(huán)手動自動結合控制，對風機系統(tǒng)進行改造，從而達到節(jié)能效果。 關鍵詞 PLC；變頻器；風機節(jié)能；溫差控制
Abstract:With China's rapid economic development, micro-electronics technology, computer technology, automation and control technology has been developed rapidly, AC variable speed technology has entered a new era, more and more light. Fan as a mining enterprise essential equipment and the production efficiency is closely related with the increasing scarcity of energy, enterprise equipment, energy saving is particularly important. The design an energy-efficient fan system instance. The article will be a business hotel fan system energy-saving programs to an unfolding narrative. This fan system from freezing, cooling pump, frozen host, cooling towers and compressors. Frozen host can be loaded along with changes in the load or load shedding, the chilled water pump and cooling water pump can not make the necessary adjustments with the load change, so there is a lot of waste. The design combines the operating characteristics of the hotel fan system, energy-saving fan water circulation system, so as to achieve the energy saving effect. Keywords PLC inverter fan energy temperature control |
