制冷原理和機構

制(zhi)冷(leng)循(xun)環(huan)均采用逆(ni)卡若循(xun)環(huan)，該(gai)循(xun)環(huan)由兩個等(deng)溫(wen)過(guo)程(cheng)(cheng)和(he)兩個絕(jue)(jue)熱(re)過(guo)程(cheng)(cheng)組成，其過(guo)程(cheng)(cheng)如下：制(zhi)冷(leng)劑(ji)(ji)經壓(ya)縮(suo)機絕(jue)(jue)熱(re)壓(ya)縮(suo)到(dao)較高(gao)(gao)的壓(ya)力，消耗了功(gong)(gong)使排(pai)氣溫(wen)度升高(gao)(gao)，之(zhi)后制(zhi)冷(leng)劑(ji)(ji)經冷(leng)凝器等(deng)溫(wen)地(di)和(he)四周(zhou)介質進行熱(re)交(jiao)換將熱(re)量傳給四周(zhou)介質。后制(zhi)冷(leng)劑(ji)(ji)經截(jie)流閥(fa)絕(jue)(jue)熱(re)膨(peng)脹(zhang)做(zuo)功(gong)(gong)，這時制(zhi)冷(leng)劑(ji)(ji)溫(wen)度降低(di)。最后制(zhi)冷(leng)劑(ji)(ji)通過(guo)蒸發器等(deng)溫(wen)地(di)從(cong)溫(wen)度較高(gao)(gao)的物體吸熱(re)，使被冷(leng)卻物體溫(wen)度降低(di)。此循(xun)環(huan)周(zhou)而復(fu)始從(cong)而達到(dao)降溫(wen)之(zhi)目(mu)的。

產(chan)品簡介：

可程(cheng)式恒溫(wen)恒濕(shi)試(shi)(shi)(shi)驗(yan)箱適(shi)用(yong)(yong)于(yu)電(dian)(dian)(dian)工、電(dian)(dian)(dian)子、儀器(qi)(qi)儀表及其它產品、零部件(jian)及材(cai)料(liao)在(zai)高(gao)低(di)(di)溫(wen)交變濕(shi)熱環(huan)境下貯(zhu)存、運輸、使用(yong)(yong)時(shi)的(de)(de)適(shi)應性(xing)試(shi)(shi)(shi)驗(yan)；是各類(lei)電(dian)(dian)(dian)子、電(dian)(dian)(dian)工、電(dian)(dian)(dian)器(qi)(qi)、塑膠等原材(cai)料(liao)和器(qi)(qi)件(jian)進行耐寒、耐熱、耐濕(shi)、耐干性(xing)試(shi)(shi)(shi)驗(yan)及品管工程(cheng)的(de)(de)可靠性(xing)測試(shi)(shi)(shi)設備；特別適(shi)用(yong)(yong)于(yu)光纖、LCD、晶體、電(dian)(dian)(dian)感、PCB、電(dian)(dian)(dian)池、電(dian)(dian)(dian)腦、手機等產品的(de)(de)耐高(gao)溫(wen)、耐低(di)(di)溫(wen)、耐潮濕(shi)循(xun)環(huan)試(shi)(shi)(shi)驗(yan)。

節能設計

除了(le)(le)充(chong)分考(kao)慮制冷(leng)機組的安全保護、高效率(lv)運(yun)用各(ge)環節(jie)(jie)外，同時采取了(le)(le)多重節(jie)(jie)能措施(shi)：如：制冷(leng)系(xi)統(tong)的制冷(leng)量調節(jie)(jie)、氣(qi)液旁(pang)路調節(jie)(jie)、蒸發溫度調節(jie)(jie)等(deng)，在(zai)任(ren)何(he)低(di)(di)溫溫度點(dian)恒溫時，無需加熱平衡，運(yun)行功率(lv)可降(jiang)(jiang)低(di)(di)至一半，使(shi)制冷(leng)系(xi)統(tong)的運(yun)行費用和故障率(lv)下降(jiang)(jiang)到較(jiao)為經濟(ji)的狀(zhuang)態。

采用(yong)智能型自(zi)動轉換(huan)膨脹系統(tong),根據(ju)(ju)負載自(zi)動調整冷媒流量+智能型電(dian)熱功率數據(ju)(ju)值(%)匹配升降溫(負載)自(zi)動模(mo)擬輸(shu)出功率數據(ju)(ju)輸(shu)出值.此設計(ji)(ji)比傳統(tong)設計(ji)(ji)可省(sheng)電(dian)30%以(yi)上(shang).
