She planned to have children once she had achieved career success so she could provide a stable environment for her baby. After 10 years, Xiao felt the time was right, and she tried to conceive for about six months, but was unable to bee pregnant. I conducted prehensive physical checkups. The results suggested that Xiao39。 menu some culinary touches from other countries, such as China and Mexico, and customers love such innovation, he says. He started his career as an apprentice in a Chinese kitchen in 1993. By chance he learned from a French chef in 1994, and soon became enamored with the world of Western food. During the next couple of years, he received strict training in Western culinary art from French, Chinese and German chefs. That was rare for a Chinese chef in the 1990s, he says－and so was being a Chinese chef who spoke fluent English. When an American entrepreneur invited him to join in his startup Blue Frog in 2000, Lin didn39。s work can be a way to unwind. It is true for He Wenjun, whose workplace is right near the forest park. She discovered her athletic aptitude at the age of seven, when she began playing tennis. Then she turned to jogging, and she has persevered with it for 10 years. I e to jog almost every day after work, whenever I have time. I think jogging is good for my health. And for me, a girl, it helps me to achieve to eternal goal, to keep slim, He said. He says she prefers jogging alone, so she can focus better. She loves jogging, even during Beijing39。Changshaserieschildren39。willgreattophoursisprevalence450forcanthingswilltobasedsurveymedicaljointlyannouncedEyeevaluate在蔡志敏老師的指導(dǎo)下，一步步解決相關(guān)問題，致使畢業(yè)設(shè)計(jì)能夠如期完成。（2）.功率消耗：14VA。選用霍尼韋爾系列的P7620C0040A壓差傳感器，其主要特性如下：（1）.精度 ≤ 177。因此選用霍尼韋爾3臺(tái)Excel50設(shè)備。圖332變頻控制回路方案 CARE軟件編程（1）.通過DDC變頻進(jìn)行CARE軟件編程，主要對(duì)中央空調(diào)變頻改造部件進(jìn)行編寫。節(jié)能效果顯著。（3） 冷凍水供水水流量控制：通過供水總管上的流量閥門FV104控制供水水流量，送入DDC（DI、DO)中。而節(jié)能是一項(xiàng)基本國(guó)策，也是河源職業(yè)技術(shù)學(xué)院達(dá)成省內(nèi)高校先進(jìn)校園的重量考核標(biāo)準(zhǔn)。 設(shè)計(jì)（論文）題目河職院報(bào)告廳中央空調(diào)節(jié)能改造學(xué) 院： 電子與信息工程學(xué)院 學(xué)生姓名： 不再是好學(xué)生 專業(yè)班級(jí)： 樓宇智能化工程技術(shù)一班 學(xué) 號(hào)： 指導(dǎo)教師： 蔡老師 年 月 日目錄 1 1 1 2 3 3三. 系統(tǒng)設(shè)計(jì) 3 4 4 4 5 5 6 CARE軟件編程 7 10 10 10 11 11 CARE軟件編程 12 16 17 17 18 19 19 20 21 21六．施工進(jìn)度表 22 22 231河源職業(yè)技術(shù)學(xué)院報(bào)告廳屬于河源職業(yè)技術(shù)學(xué)院圖書館第三期工程；建筑面積為600平方米，整體建筑為三層；樓高12米；中央空調(diào)機(jī)房設(shè)置在三樓處，冷卻塔則設(shè)置在樓頂處。河源職業(yè)技術(shù)學(xué)院報(bào)告廳是河源職業(yè)技術(shù)學(xué)院校園文化以及學(xué)生才藝表演、展現(xiàn)之地，人員密集、流動(dòng)大，對(duì)環(huán)境的要求也是要求相當(dāng)高的；尤其是環(huán)境的濕度、溫度和空氣質(zhì)量。（2） 冷凍水供/回水溫監(jiān)測(cè)：供水總管上的溫度傳感器TE201經(jīng)監(jiān)測(cè)冷凍水供水溫度后；將檢測(cè)信號(hào)送入DDC(AI)中；回水總管上的溫度傳感器TE102檢測(cè)冷凍水回水溫度，檢測(cè)信號(hào)也送入DDC（AI)中。A、 調(diào)節(jié)效率高，可以實(shí)現(xiàn)從0～50 Hz范圍內(nèi)的無級(jí)調(diào)速。B、變頻器主路和旁通各設(shè)一只主斷路器，同時(shí)兩者之間進(jìn)行電氣連鎖，防止主路和旁通同時(shí)投入工作。
