style="font-size:14px;">熱是由于溫度差而傳遞的能量的一種形式。熱量或多或少存在于各處。作為能量的一種形式，它既不能產(chǎn)生也不能銷毀，盡管其他形式的能量也可以轉(zhuǎn)化為熱量，反之亦然。重要的是要記住，熱能只能在一個方向上傳播。從較熱的物體到較冷的物體，物質(zhì)或區(qū)域。寒冷是一個相對術(shù)語，指的是物體，物質(zhì)或區(qū)域中沒有熱量。另一個定義將其描述為不存在熱量，尚未設(shè)計出實現(xiàn)“零”（從所有物體，物質(zhì)或區(qū)域中清理干凈所有熱量的狀態(tài)）的過程。從理論上講，該零點在華氏溫度計刻度上比零下低459.69度，在攝氏溫度計刻度上比零下低273.16度。制冷或冷卻過程是從選定的物體，物質(zhì)或空間中去除多余的熱量，并將其傳遞到另一物體，物質(zhì)或空間中。排熱會降低溫度，可以通過使用冰，雪，冷凍水或機械制冷來實現(xiàn)。機械制冷，是指為了</span><span style="font-size:14px;">傳遞熱量而利用布置在“制冷系統(tǒng)”中的機械組件。制冷劑是交替壓縮和冷凝為液體，然后在泵送通過機械制冷系統(tǒng)循環(huán)時使其膨脹為蒸氣或氣體的化學(xué)化合物。</span> 制冷機組哪家經(jīng)銷商比較好？云南冰水機組批發(fā)公司</p><p
