二、工作原理：

工作原理：由加熱(re)系統和制冷系統產生升溫(wen)(wen)和降溫(wen)(wen)、用溫(wen)(wen)控儀進(jin)行調控.

1.當(dang)溫(wen)(wen)度低于下(xia)限溫(wen)(wen)度20℃時(shi)溫(wen)(wen)控儀繼(ji)電(dian)(dian)器(qi)(qi)(qi)開始工(gong)(gong)(gong)作箱內溫(wen)(wen)度高于20℃繼(ji)電(dian)(dian)器(qi)(qi)(qi)斷電(dian)(dian)電(dian)(dian)熱(re)器(qi)(qi)(qi)停(ting)止加熱(re)。保(bao)(bao)持箱內20℃恒溫(wen)(wen)當(dang)箱內溫(wen)(wen)度高于20℃時(shi)制(zhi)冷系統(tong)開始工(gong)(gong)(gong)作箱內溫(wen)(wen)度低于20攝氏度時(shi)制(zhi)冷系統(tong)停(ting)止工(gong)(gong)(gong)作保(bao)(bao)持箱內20±1℃這樣連續(xu)反復工(gong)(gong)(gong)作。達到水泥式樣養護工(gong)(gong)(gong)作。   

2.溫度(du)(du)(du)控(kong)制(zhi)器采用超聲波加(jia)(jia)速(su)加(jia)(jia)濕(shi)(shi)(shi)器加(jia)(jia)濕(shi)(shi)(shi)當箱(xiang)內(nei)(nei)溫度(du)(du)(du)達不到(dao)所需控(kong)制(zhi)濕(shi)(shi)(shi)度(du)(du)(du)時。加(jia)(jia)濕(shi)(shi)(shi)器西東(dong)向(xiang)箱(xiang)內(nei)(nei)加(jia)(jia)濕(shi)(shi)(shi)達到(dao)自(zi)動停止以(yi)保箱(xiang)內(nei)(nei)濕(shi)(shi)(shi)度(du)(du)(du)≥95%以(yi)上。
