style="text-indent:25px">螺桿式冷凍壓縮機是一種回轉式容積式壓縮機。它利用螺桿的齒槽容積和位置的變化來完成蒸氣的吸入、壓縮和排氣過程。無油螺桿壓縮機在本世紀三十年代問世，主要用于壓縮空氣。后來汽缸內噴油的螺桿式壓縮機出現(xiàn)，性能得到提高，噴油式螺桿壓縮機已是冷凍壓縮機中主要機種之一。螺桿式壓縮機分為雙螺桿和單螺桿兩大類，雙螺桿壓縮機習慣上稱為螺桿式壓縮機。變排量壓縮機可以根據(jù)設定的溫度自動調節(jié)功率輸出。空調控制系統(tǒng)不采集蒸發(fā)器m風口的溫度信號，而是根據(jù)空調管路內壓力變化信號來控制壓縮機的壓縮比從而自動調節(jié)m風口溫度。在制冷的全過程中，壓縮機始終是工作的，制冷強度的調節(jié)完全依賴裝在壓縮機內部的壓力調節(jié)閥來控制。當空調管路內高壓端壓力過高時，壓力調節(jié)閥縮短壓縮機內活塞行程以減小壓縮比，這樣就會降**冷強度。當高壓端壓力下降到一定程度，低壓端壓力上升到一定程度時，壓力調節(jié)閥則增大活塞行程以提高制冷強度。氟機冷凍機一般體積小、噪音小、較可靠、自動化程度高、適用范圍廣，適于鄉(xiāng)村小型冷庫用冷凍機。</p><div
