门(men)窗(chuang)附框高低(di)(di)温(wen)(wen)(wen)反复尺寸(cun)变化率(lv)(lv)试(shi)(shi)(shi)验(yan)箱(xiang)(xiang)(xiang)在设定(ding)温(wen)(wen)(wen)度(du)(du)(du)(du)时(shi)需(xu)要(yao)(yao)考虑多个因(yin)素。首先(xian)，要(yao)(yao)确定(ding)试(shi)(shi)(shi)验(yan)箱(xiang)(xiang)(xiang)的(de)(de)(de)(de)工作(zuo)温(wen)(wen)(wen)度(du)(du)(du)(du)范围。根据试(shi)(shi)(shi)验(yan)的(de)(de)(de)(de)需(xu)求(qiu)和(he)标准要(yao)(yao)求(qiu)，可以(yi)(yi)(yi)确定(ding)试(shi)(shi)(shi)验(yan)箱(xiang)(xiang)(xiang)所需(xu)的(de)(de)(de)(de)温(wen)(wen)(wen)度(du)(du)(du)(du)和(he)温(wen)(wen)(wen)度(du)(du)(du)(du)。其(qi)次，要(yao)(yao)选择(ze)合适(shi)的(de)(de)(de)(de)加(jia)(jia)热(re)和(he)制(zhi)(zhi)冷方(fang)(fang)式。常用的(de)(de)(de)(de)加(jia)(jia)热(re)方(fang)(fang)式有电加(jia)(jia)热(re)和(he)蒸发器(qi)加(jia)(jia)热(re)，而制(zhi)(zhi)冷则通常采(cai)(cai)用制(zhi)(zhi)冷剂循环或者压缩机制(zhi)(zhi)冷。根据试(shi)(shi)(shi)验(yan)箱(xiang)(xiang)(xiang)的(de)(de)(de)(de)大小和(he)试(shi)(shi)(shi)验(yan)箱(xiang)(xiang)(xiang)结构(gou)的(de)(de)(de)(de)特点，选择(ze)适(shi)合的(de)(de)(de)(de)加(jia)(jia)热(re)和(he)制(zhi)(zhi)冷方(fang)(fang)式。在设定(ding)温(wen)(wen)(wen)度(du)(du)(du)(du)时(shi)，可以(yi)(yi)(yi)使用温(wen)(wen)(wen)度(du)(du)(du)(du)控(kong)制(zhi)(zhi)仪来(lai)实现自动控(kong)制(zhi)(zhi)，保持(chi)(chi)温(wen)(wen)(wen)度(du)(du)(du)(du)稳(wen)定(ding)。在设定(ding)温(wen)(wen)(wen)度(du)(du)(du)(du)时(shi)，需(xu)要(yao)(yao)考虑试(shi)(shi)(shi)验(yan)箱(xiang)(xiang)(xiang)内(nei)部(bu)的(de)(de)(de)(de)温(wen)(wen)(wen)度(du)(du)(du)(du)均(jun)匀(yun)性(xing)(xing)，因(yin)此可以(yi)(yi)(yi)在试(shi)(shi)(shi)验(yan)箱(xiang)(xiang)(xiang)内(nei)部(bu)采(cai)(cai)用通风(feng)方(fang)(fang)式，通过强制(zhi)(zhi)对流来(lai)增强温(wen)(wen)(wen)度(du)(du)(du)(du)均(jun)匀(yun)性(xing)(xing)。同时(shi)，试(shi)(shi)(shi)验(yan)箱(xiang)(xiang)(xiang)内(nei)部(bu)还(hai)可以(yi)(yi)(yi)设置温(wen)(wen)(wen)度(du)(du)(du)(du)传感器(qi)，实时(shi)监测温(wen)(wen)(wen)度(du)(du)(du)(du)变化，并及时(shi)调整温(wen)(wen)(wen)度(du)(du)(du)(du)控(kong)制(zhi)(zhi)器(qi)的(de)(de)(de)(de)输出(chu)以(yi)(yi)(yi)维持(chi)(chi)设定(ding)温(wen)(wen)(wen)度(du)(du)(du)(du)。另(ling)外，还(hai)要(yao)(yao)考虑试(shi)(shi)(shi)验(yan)箱(xiang)(xiang)(xiang)的(de)(de)(de)(de)绝(jue)缘(yuan)性(xing)(xing)能，以(yi)(yi)(yi)避免热(re)量的(de)(de)(de)(de)外泄(xie)和(he)影响温(wen)(wen)(wen)度(du)(du)(du)(du)稳(wen)定(ding)性(xing)(xing)。通过合理(li)设置温(wen)(wen)(wen)度(du)(du)(du)(du)，可以(yi)(yi)(yi)使门(men)窗(chuang)附框高低(di)(di)温(wen)(wen)(wen)反复尺寸(cun)变化率(lv)(lv)试(shi)(shi)(shi)验(yan)箱(xiang)(xiang)(xiang)达到预期的(de)(de)(de)(de)测试(shi)(shi)(shi)效果(guo)。
