【正文】 s economic development and policies for a long period of time, the northern coalfired boilers generally solve the problem of heating in winter. Water source heat pump is running, just recharge through the extraction of groundwater extraction and energy, irrigation pumping in the whole process, the pipeline is closed, and will not cause pollution of groundwater. Comparison of CO2 emissions from coalfired boilers and electric drive with the same fuel amount of CO2 emissions can be reduced by 30% 50%, in environmental protection will play a significant role. 2, the promotion prospects of water source heat pump technology ① stresses energy saving, is the heating of structural adjustment in Shenyang City, and gradually replace coalfired boiler room in fact practical way. As for the new environmentally sustainable development and public awareness, the world and the structure of all energy use in China is changing, from the original coal, oil, heating the transition to clean energy such as natural gas and electricity. Shenyang is more for the serious air pollution as one of the cities, its air pollution control policy to include the adjustment of energy structure, mainly from coal to natural gas and electricity alternative energy sources. However, although alternative energy sources can be a partial solution to the problem of air pollution, but natural gas and oil and so on are nonrenewable energy sources, from the perspective of sustainable development, we must improve energy efficiency or renewable energy looking for, and water source heat pump unit is Ideally, a device. ② irrigation through the back reuse, residential and environmental water issues to resolve. With economic development, people39。s rapid growth rate of residential airconditioning installation. Shenyang has a residential rate of over 20% of airconditioning, home air conditioners and currently has a rapid growth rate is still very likely to be the refrigerator, color TV and after a rapid spread of home appliances. This environment is no longer just a residential heating problems, but to consider uniform heating and air conditioning needs. To this end, the use of deep well recharge water source heat pump method may be to meet this demand for residential heating, refrigeration and air conditioning mode. First, the concept of water source heat pump technology and principle Water source heat pump technology is the use of the Earth39。而水源熱泵抽取的水可以在回灌之前創(chuàng)造一個水文景觀后，通過處理技術(shù)達(dá)到回灌水標(biāo)準(zhǔn)后再灌入地下，就很好的解決了這一問題。比較燃煤鍋爐 CO2 排放量與用相同燃料產(chǎn)生電驅(qū)動所排放的 CO2 量，可減少 30%50%，在環(huán)保中將發(fā)揮很大的作用。利用這次機會，我們將進(jìn)一步研究這種濾管的熱 傳導(dǎo)性能及滲透能力，并申請專利，促進(jìn)這項技術(shù)在沈陽的推廣使用。 我公司根據(jù)沈陽地區(qū)的水文地質(zhì)條件，參考國內(nèi)外有關(guān)研究成果，通過具體工程實踐，認(rèn)為抽、灌井間距縮短到 60m 是完全可行的，如國府肥牛熱泵抽灌井間距為 50m，運行情況良好，未出現(xiàn)抽灌井 “ 熱貫通 ” 現(xiàn)象。沈陽 市自動化所也因回灌井無法布開，導(dǎo)致部分建筑無 131 法利用水源熱泵供暖。 四、水源熱泵技術(shù)在沈陽地區(qū)應(yīng)用及存在的問題 水源熱泵技術(shù)是從 1998 年引入沈陽地區(qū)的，比較早的有東電宿舍樓、沈 陽自動化所、遼寧科技大廈、醫(yī)大二院等，供暖制冷面積大的 10 萬 m2 以上，小的只有 2020m2。地源熱泵最大的優(yōu)勢是與常規(guī)供熱和制冷空調(diào)系統(tǒng)相比少消耗電能。其中清華大學(xué)經(jīng)過多年在多工況水源熱泵的研究已經(jīng)形成產(chǎn)業(yè)化的成果，已建成多個示范工程。由于地下水通過換熱器 3 換熱后排回地下，僅僅利用了地下水的冷量（熱量），而不消耗一滴水資源，地下水的整個流程都不與空氣接觸，因此也不會造成地下水資源的污染。地下水從深井 1 中抽出進(jìn)入板式熱交換器 3，與樓內(nèi)循環(huán)水系統(tǒng)的水換熱后，再通過深井 2 排到地下。另一方面，近年來我國住宅空調(diào)安裝率迅速增長。 127 附錄 F 水源熱泵中央空調(diào)回灌技術(shù)的推廣 簡介：在未來的幾年中，中國面臨著巨大的能源壓力。沈陽居民住宅空調(diào)擁有率已超過 20％，并且目前家用空調(diào)擁有率仍在飛速增長，很可能成為冰箱、彩電后迅速普及的又一種家電。循環(huán)水系統(tǒng)經(jīng)住宅樓內(nèi)管網(wǎng)送入各戶，經(jīng)各戶的水源熱泵產(chǎn)生熱水（冬季）或冷水（夏季）送入末端裝置，滿足供熱或空 調(diào)的要求。 129 二、水源熱泵中央空調(diào)技術(shù)在國內(nèi)外發(fā)展動態(tài) 水源熱泵技術(shù)（以下簡稱 GWHP）的提出始于英、美兩國，美國從 20 世紀(jì) 30 年代即開始應(yīng)用?？梢灶A(yù)計，該項技術(shù)將會成為 21 世紀(jì)最有效的供熱和供冷空調(diào)技術(shù)。在適宜的條件下比空氣熱泵系統(tǒng)節(jié)省能源 40%以上，比電采暖 節(jié)能 70%以上。比較典型的是沈陽自動化研究所，該所建筑面積 萬 m2， 1999 年引入水源熱泵中央空調(diào)系統(tǒng)用以替代原有的 2 臺燃煤鍋爐。還有部分用戶為解決回灌問題，直接將水排入下水管道，沒有回灌入地下，浪費了大量的地下水資源。地王國際花園抽、灌井群最小間距為 60m。 六、水源熱泵技術(shù)在沈陽的推廣應(yīng)用 水源熱泵技術(shù)在沈陽推廣的意義 ① 節(jié)能 、運行費用低 由于水源熱泵是以水作為熱源和供熱介質(zhì)的供熱制冷技術(shù)。 推廣水源熱泵技術(shù)的應(yīng)用前景 ① 強調(diào)節(jié)能環(huán)保，是沈陽市供暖 結(jié)構(gòu) 調(diào)整，逐步替代燃煤鍋爐房其實可行的方式。按目前的技術(shù)來看，這是切實可行的。s surface shallow water such as groundwater, rivers and lakes in the absorption of solar energy and geothermal energy and the formation of low temperature heat resources, and heat pump principle, by a small amount of high 135 energy input, low heat to achieve high heat transfer a technology. Earth39。s living standards improve, people yearn for a living environment surrounded by water. However, the current situation of China39。 ② Environmental In the traditional Chinese concept of airconditioning systems, due to the country39。s economy to maintain a high rate of growth, on the other hand, it must consider environmental protection and sustainable development issues. So for greater energy efficiency, requiring adjustment of energy structure. With the current housing marketoriented reforms in China, the rapid development of new mercial residential area, with increasing emphasis on urban environmental issues and energy structure adjustment, new district general in Shenyang will no longer run by coalfired boiler room heating, the manner in which can be economical and clean way to solve these problems the new district heating bee a major issue in residential constru
