冰蓄冷中央空調(diào)及其相關(guān)系 統(tǒng) I 摘 要 冰蓄冷中央空調(diào)系統(tǒng)是現(xiàn)代化大型建筑物不可缺少的配套設(shè)施之一,冰蓄冷空調(diào)主要在夜間低谷電力時(shí)段將建筑物所需空調(diào)冷量部分或全部制備好,并以冰的形式儲存起來,在非電力低谷時(shí)段融冰供冷的一種空調(diào)系統(tǒng)。由于低谷電力時(shí)段電價(jià)較低,用戶得以大幅度降低空調(diào)使用費(fèi)。由于冰蓄冷中央空調(diào)行業(yè)是一個(gè)剛剛形成的行業(yè),冰蓄冷中央空調(diào)在我國具有很好的發(fā)展前景。本文的意義在于以便使冰蓄冷中央空調(diào)行業(yè)能迅速發(fā)展,同時(shí)宏觀上起到移峰填谷的作用,平衡電網(wǎng)需求側(cè)的運(yùn)行。 隨著科學(xué)技術(shù)的日益成熟,利用變頻器、 PLC、數(shù)模轉(zhuǎn)換模塊、溫度傳感 器、溫度模塊等器件的有機(jī)結(jié)合,構(gòu)成溫差閉環(huán)自動(dòng)控制系統(tǒng),自動(dòng)調(diào)節(jié)水泵的輸出流量,達(dá)到節(jié)能目的的提供了可靠的技術(shù)條件。 關(guān)鍵詞: PLC,冰蓄冷技術(shù),中央空調(diào),控制功能 冰蓄冷中央空調(diào)及其相關(guān)系 統(tǒng) II ABSTRACT IceThermalStorage Center Air Conditioning System is one of modern largescale building essential supporting facilities, IceThermalStorage Center Air Conditioning System is a machine system that can turn electricity into cold energy at night when the need for electricity is low and store the cold energy in the state of ice. In the daytime that the need of electricity is high the system provides cold air for the building by melting the ice. In this way the user can save a lot of money on account that the electricity fee is high in daytime than at night. So the writer draws the conclusion that IceThermalStorage Center Air Conditioning System, as new product, has a bright business future in China. The conclusion drawn by the writer in this thesis can be used as reference for the IceThermalStorage Center Air Conditioning System business。 the government officer can balance the need of electricity between daytime and night theoretically using the principles announced by the writer. Along with the science and technology matures, using anic bination of inverter, PLC, digital analog conversion module, temperature sensor and temperature module to thermoelectric closedloop automatic control technology which can adjust output flow rate automatically to save energy.
