摘要:本文基于變頻器設計并實現(xiàn)了一套能有效實現(xiàn)中央空調節(jié)能的系統(tǒng)。簡述了中央空調系統(tǒng)的工作原理.詳細介紹了該節(jié)能系統(tǒng)的結構、主要功能、性能特點及實現(xiàn)方案。本系統(tǒng)是在時現(xiàn)有中央空調工作原理及現(xiàn)有的各種中央空調節(jié)能控制系統(tǒng)進行詳細研究和分析基礎上,設計并實現(xiàn)的,其性能可靠,節(jié)電效果顯著,還可大大延長電機、接觸器及機械散件、軸承、閥門、管道、制冷主機、熱交換器的使用壽命,避免水泵瞬間起動和瞬間停止時產(chǎn)生的水錘現(xiàn)象。
關鍵詞:變頻器;中央空調;節(jié)能系統(tǒng)
Abstract:A set of system which can efectively realizes tlle energy—saving function of the central air—conditioner based on tlle trails.ducer Was developed in tllis paper.The working principle of tlle central air—conditioner system Was simply introduced.And tlle stmc.ture. t}le main function. the performance characteristics and t}le realization method of the energy—saving system were introd uced in detail. Th is system Was designed and realized on tlle basis of detailed research and analysis of tlle working principle of the existing central air-conditioner and of all the existing kinds of energy—saving systems of tlle central air—conditioners. It has reliable perfornlaflee,obvious electricity-saving efect,and Can greatly lengthens the using time of the electromotor,the contact machine,the meehan ical elements。t}le bearing。t}le valve。t}le pipe refrigeration mainframe an d t}le heat exchanger.And it can also avoid the water ham mer phenomena produced during sudden starting and sudden stop of tlle pump.

一方面隨著全球各個經(jīng)濟領域對能源的需求不斷增長,另一方面隨著自然界能源日益減少,節(jié)約能源、追求綠色經(jīng)濟已經(jīng)成為世界上很多個國家的焦點。而中國作為一個人口如此龐大的發(fā)展中國家,在新的五年計劃中更是將這個問題擺在經(jīng)濟健康發(fā)展的首位。中央空調是能源消耗的一個很重要的方面。當前,隨著經(jīng)濟發(fā)展的13新月異,城市建設的步伐不斷加快,中央空調成為關系到人們生活和工作的重要工具之一。它作為現(xiàn)代建筑里的能耗大戶,據(jù)調查,每年的電費中中央空調耗電占整棟大樓耗電的60%左右.面對其如此高的耗電量,盡快對現(xiàn)有的各種節(jié)能控制系統(tǒng)進行深入研究并改造、開發(fā)出更加合理的節(jié)能系統(tǒng)顯得尤為重要。
