摘要:該試驗(yàn)系統(tǒng)的設(shè)計(jì)是為了研究風(fēng)冷壓縮冷凝機(jī)組性能，檢測(cè)制冷系統(tǒng)的性能，并提出針對(duì)性的改善措施，最終使系統(tǒng)的性能得到優(yōu)化。 試驗(yàn)方法采用“第二制冷劑量熱器法”，其原理是制冷系統(tǒng)產(chǎn)生的制冷量與電加熱器產(chǎn)生的熱量相交換，達(dá)到平衡時(shí)，通過(guò)測(cè)量電加熱器而得出的制冷量的一種間接試驗(yàn)方法。試驗(yàn)系統(tǒng)設(shè)置有數(shù)據(jù)自動(dòng)采集系統(tǒng)。 本次設(shè)計(jì)的主要任務(wù)是對(duì)試驗(yàn)室負(fù)荷進(jìn)行計(jì)算，設(shè)計(jì)房間尺寸，進(jìn)行總體布置。并且試驗(yàn)臺(tái)的主要部件——量熱器進(jìn)行計(jì)算。通過(guò)熱力計(jì)算，得出制冷量等性能指標(biāo)。再根據(jù)傳熱學(xué)和換熱器設(shè)計(jì)等有關(guān)文獻(xiàn)，計(jì)算出蒸發(fā)盤(pán)管的傳熱系數(shù)，從而得出蒸發(fā)盤(pán)管面積，并對(duì)其結(jié)構(gòu)設(shè)計(jì)。接下來(lái)，進(jìn)行了制冷系統(tǒng)節(jié)流機(jī)構(gòu)和附屬設(shè)備的選型。 關(guān)鍵詞：風(fēng)冷壓縮冷凝機(jī)組，試驗(yàn)系統(tǒng)，量熱器，第二制冷劑
Abstract:The test system is designed to study the performance of condensing units, air-cooled compression test the performance of the refrigeration system, and puts forward specific improvement measures, eventually make the system performance was optimized. Test method adopts "the second refrigerants calorimeter method", its principle is the refrigerating capacity and refrigeration system produce electric heaters are exchanged heat generation, balance, measured by the electric heater and the refrigerating capacity that an indirect test method. Test system Settings are automatically data acquisition system. The design of the main task is to load calculation, laboratory design room size, in overall layout. And the main part -- calorimeter test is calculated. Through the thermodynamic calculation indicates that such performance index refrigeration. And then based on heat transfer and heat exchanger design and other relevant documents, calculated evaporation coil, so as to obtain the heat transfer coefficient evaporation coil area, and its structure design. Next, the refrigeration system the throttle body and accessory equipment selection. Key words: Air-cooled compression ，testing system，calorimeter, refrigeration system |
