【正文】 設(shè)計(jì)要求進(jìn)行風(fēng)冷熱泵系統(tǒng)流程的設(shè)計(jì),并在此基礎(chǔ)上畫(huà)出系統(tǒng)流程圖,進(jìn)行循環(huán)的熱力計(jì)算。 設(shè)計(jì)任務(wù): 工質(zhì)為R410a額定工況制冷量: KW;額定工況制熱量:15 KW;額定工況: 制冷工況 室內(nèi)干球溫度27℃,濕球溫度19℃; 環(huán)境溫度Ta=35℃,濕球溫度24℃ 制熱工況 環(huán)境溫度Ta=7℃,濕球溫度6℃ 制冷劑:R410a;電源:50Hz,220V。 air。 關(guān)鍵詞:熱泵;風(fēng)冷;循環(huán)33致謝ABSTRACT Aircooled heat pump hot water unit developed rapidly in 1996 than in 1995, an increase of nearly tripled. China39。本設(shè)計(jì)為風(fēng)冷熱泵設(shè)計(jì),結(jié)合所學(xué)知識(shí)以及工程實(shí)際設(shè)計(jì)資料(經(jīng)濟(jì)效益、環(huán)境效益),要求優(yōu)化管路流程,充分發(fā)揮換熱能力。本 科 畢 業(yè) 設(shè) 計(jì) 計(jì) 算 說(shuō) 明 書(shū) 題 目 風(fēng)冷熱泵性能設(shè)計(jì)計(jì)算 系 別 機(jī) 械 工 程 系 專(zhuān) 業(yè) 熱能與動(dòng)力工程 班 級(jí) 能動(dòng)901 學(xué)號(hào) 學(xué)生姓名 指導(dǎo)老師 2013 年 06 月摘要摘 要風(fēng)冷熱泵型熱水機(jī)組發(fā)展迅速,1996年比1995年增長(zhǎng)近二倍。我國(guó)的能源政策和環(huán)境保護(hù)政策是促進(jìn)熱泵技術(shù)迅速發(fā)展的主要因素?zé)岜每照{(diào)系統(tǒng)在中國(guó)的應(yīng)用迅速增長(zhǎng),目前家用空調(diào)器總量60%為熱泵型甚至在較為寒冷的北京地區(qū),有許多用戶(hù)也喜歡在集中采暖期前后應(yīng)用熱泵型空調(diào)機(jī)組來(lái)采暖,冬季供應(yīng)熱水,夏季供應(yīng)冷水的電動(dòng)風(fēng)冷機(jī)組在集中式空調(diào)系統(tǒng)中得到了廣泛的應(yīng)用,今后的應(yīng)用將更為普及。該設(shè)計(jì)詳細(xì)介紹了系統(tǒng)方案的確定和該系統(tǒng)循環(huán)熱力計(jì)算、壓縮機(jī)的選型計(jì)算、冷凝器的選型校核、蒸發(fā)器的選型校核、節(jié)流機(jī)構(gòu)的選型、經(jīng)濟(jì)性分析。s energy policy and environmental policy is to promote the rapid development of heat pump technology is a major factor in heat pump air conditioning system in China is rapidly growing, currently 60% of total household airconditioner heat pump even in the colder regions of Beijing, there are many users Like the centralized heating period before and after the application of heat pump type air conditioning units for heating, hot water in winter, summer, supply of cold water in an electric aircooled central air conditioning system has been widely used, future applications will be more popular. air conditioning system has been widely used, future applications will be more popular. The design for the aircooled heat pump design, bined with the knowledge and practical engineering design information (economic and environmental benefits), requires optimization of process . The design details of the system and the system determines the program cycle thermodynamic calculation, sizing the pressor, condenser selection checking, evaporator selection, throttle bodies selection, economic analysis.KEY WORDS: heat pump。 circulation 目 錄摘 要 IABSTRACT II目 錄 III1緒論 1 設(shè)計(jì)目的 1 設(shè)計(jì)要求: 1 設(shè)計(jì)具體要求 12設(shè)計(jì)任務(wù)、依據(jù)及方案 3 流程設(shè)計(jì)及熱力計(jì)算 3 流程圖設(shè)計(jì) 3 循環(huán)熱力計(jì)算設(shè)計(jì)參數(shù) 3 4 7 10 16 26 27 28 293輔助設(shè)備選型和經(jīng)濟(jì)性分析 30 輔助設(shè)備選型 30 30 30 30 熱力經(jīng)濟(jì)性 30 30致 謝 32參考文獻(xiàn) 33 1緒 論 : 通過(guò)風(fēng)冷熱泵的設(shè)計(jì),綜合應(yīng)用所學(xué)的基礎(chǔ)理論和專(zhuān)業(yè)知識(shí),分析和解決問(wèn) 題,掌握設(shè)計(jì)和開(kāi)發(fā)的基本方法和技能,了解風(fēng)冷熱泵的發(fā)展趨勢(shì),為今后更好的從事相關(guān)工作和學(xué)習(xí)打下良好基礎(chǔ)。 設(shè)計(jì)要求: 系統(tǒng)流程的設(shè)計(jì)
