style="text-indent:25px">冷凍機(jī)產(chǎn)冷量多少，與系統(tǒng)運轉(zhuǎn)工況有直接關(guān)系，對于同一臺結(jié)構(gòu)，轉(zhuǎn)速，制冷劑種類均已確定的壓縮機(jī)，由于運轉(zhuǎn)工況改變，操作管理不同，其產(chǎn)冷量和耗能也隨著變化。 1、隨著蒸發(fā)溫度的降低，壓縮機(jī)的壓縮比增大，單位產(chǎn)冷量耗能增加。當(dāng)蒸發(fā)溫度每降低1℃，則要多耗電3%-4%。因此盡可能縮小蒸發(fā)溫差，提高蒸發(fā)溫度，不但節(jié)約電耗，還可以提高冷間的相對濕度。 2、隨著冷凝溫度的升高，壓縮機(jī)的壓縮比增大，單位產(chǎn)冷量的耗能增加。冷凝溫度在25℃-40℃之間，每升高1℃，增加耗電量3.2%左右。??? 3、冷凝器和蒸發(fā)器的換熱表面覆有油層時，會引起冷凝溫度升高，蒸發(fā)溫度降低，導(dǎo)致產(chǎn)冷量減少和耗電量增加。冷凝器內(nèi)表面上積有0.1mm厚油層時，將使壓縮機(jī)產(chǎn)冷量下降16.6，耗電量增加12.4；蒸發(fā)器內(nèi)表面上積油0.1mm厚油層時，為了保持已定的低溫要求，蒸發(fā)溫度就下降2.5℃，耗電量增加9.7%。??? 4、當(dāng)空氣聚集在冷凝器內(nèi)時，會引起冷凝壓力升高，不凝結(jié)氣體分壓力達(dá)到1.96105Pa時，壓縮機(jī)耗電量要增加18%。江蘇專業(yè)冷凍機(jī)價位匹配合理、性能可靠的冷凍機(jī)機(jī)組，能滿足產(chǎn)品所要求的冷庫制冷量和冷庫貯藏工藝要求。</p><div style="width:100%;text-align:

style="text-indent:25px">冷凍壓縮機(jī)吸入的氣體允許一定的過熱度，但過熱度太大，吸入氣體的比容增加，其產(chǎn)冷量降低，相對耗電量增加。蒸發(fā)器表面覆蓋一層霜層，使其傳熱系數(shù)減小，尤其是翅片管外表面結(jié)霜時，不但增加了傳熱熱阻，而且使翅片間的空氣流動困難，減少外表的傳熱系數(shù)和散熱面積。當(dāng)室內(nèi)溫度低于0℃時，蒸發(fā)器管組兩側(cè)溫差為10℃時，蒸發(fā)器工作一個月后，其傳熱系數(shù)大約是結(jié)霜前70左右。如果壓縮機(jī)來霜，迅速關(guān)小吸氣閥，急劇地降低產(chǎn)冷量，相對增加耗電量。</p><p style="text-indent:25px">冷凍機(jī)的特性：來自蒸發(fā)器的制冷劑蒸汽先進(jìn)入低壓級汽缸壓縮到中間壓力，經(jīng)過中間冷卻后再進(jìn)入高壓級汽缸，壓縮到冷凝壓力進(jìn)入冷凝器中。一般蒸發(fā)溫度在-25℃~-50℃時，應(yīng)采用雙級壓縮機(jī)進(jìn)行制冷。制冷系統(tǒng)由蒸發(fā)器、雙級壓縮機(jī)、油分離器、冷凝器、中間冷卻器、貯氨器、氨液分離器、節(jié)流閥及其它附屬設(shè)備等組成，相互間通過管子聯(lián)接成一個封閉系統(tǒng)。其中，中間冷卻器利用少量液態(tài)制冷工質(zhì)在中間壓力下汽化吸熱，使低壓級排出的過熱蒸汽得到冷卻，降低高壓級的吸氣溫度，同時還使高壓液態(tài)制冷工質(zhì)得到冷卻。冷凍機(jī)企業(yè)想要抓住這個機(jī)遇實現(xiàn)大發(fā)展的話，必須在科技研發(fā)上面下功夫。</p><div
