摘 要:本文對風機盤管性能試驗系統(tǒng)進行了設計，由于風機盤管機組作為集中式空調(diào)系統(tǒng)的一種末端裝置，具有施工安裝方便，能量調(diào)節(jié)靈活等特點，被廣泛適用于賓館、飯店等多房間的空調(diào)系統(tǒng)中。近年來隨著風機盤管機組型式的多樣化，其使用場合更加廣泛。自19世紀70年代初我國開始生產(chǎn)風機盤管機組以來，無論數(shù)量還是質(zhì)量都有了很大的提高，其主要性能指標與國外產(chǎn)品已無差距。但是，風機盤管機組產(chǎn)品存在著性能規(guī)格差異較大，產(chǎn)品質(zhì)量良莠不齊等諸多問題。一些設備達不到設計和使用要求，行業(yè)管理部門很難對風機盤管機組質(zhì)量作出定量判斷，社會反響強烈。為此，我們進行了風機盤管性能試驗系統(tǒng)設計。 由于風機盤管試驗室的研究涉及知識產(chǎn)權及其它眾多因素，國內(nèi)外公開發(fā)表的相關資料較少。國外研究機構雖具有較先進的測試技術，但涉及費用較高；國內(nèi)研究所在工況穩(wěn)定時間、精度及可靠性方面與國外尚有一定差距。在市場競爭激烈、經(jīng)濟全球化的今天，試驗室評定與表示方法的統(tǒng)一已經(jīng)成為科技交流和國際貿(mào)易的迫切要求，它使各國進行的測量及其所得到的結果可以進行互相比對，取得互相承認和共識。 依據(jù)國內(nèi)外相關標準，對風機盤管性能試驗系統(tǒng)的進行了深入探索。該系統(tǒng)的建設涉及工藝、自控和計算機自動測試等專業(yè)。技術難度大, 控制參數(shù)多, 測量范圍大, 精度要求極高, 試驗工況復雜。 關鍵詞： 風機盤管，性能試驗，空氣焓差法，試驗室
ABSTRACT:This paper fan-coil performance tests on the design, because system fan-coil unit as a central air-conditioning system with end equipment, installation is convenient, flexible, and other characteristics, energy regulation is widely suitable for hotels, restaurants, etc. In the room of air-conditioning systems In recent years, with fan coil units types of diversification, its use occasions more extensive. Since the 19th century in China in the early 70s begin production since fan coil units, whether quantity or the quality had the very big enhancement, its main performance index has no gap with foreign products. But, fan coil units product performance specification differences exist, product quality problems such as the good and bad are intermingled. Some equipment can not meet the design and application requirements, industry management department is difficult to fan coil units to make quantitative judgment, quality of social repercussions strongly. Therefore, we conducted fan-coil performance test system design. Because of the fan-coil laboratory studies involving intellectual property and many other factors, and open the relevant data published less. Although foreign research institutions with relatively advanced testing techniques involved, but the cost is higher; Domestic researches in working stability time, accuracy and reliability and there are certain foreign gap. In intense market competition, economic globalization today, laboratory evaluation and said the unity of science and technology method has become the urgent demand of the exchange and international trade, it makes the measurement and various countries in the results obtained than each other, can recognize each other and consensus. According to the domestic and foreign relevant standards, fan-coil performance testing system has carried on the thorough exploration. The construction of this system involving process, control and computer automatic test, and other professionals. Technical difficulties, and control parameters measurement range, high accuracy requirements, test condition complex. Keyword: Fan coil, performance testing, air enthalpy difference method, lab |
