風冷冷水機組制冷系統設計常見問題分析

  一、風冷冷水機組(熱泵)主要由壓縮機、風冷冷凝器、電磁四通換向閥、節流膨脹機構、板式換熱器及附屬部件氣液分離器、油分離器、過濾器以及單向閥等各部件所組成。夏季制冷循環，系統內制冷劑按實線箭頭所標的方向流動；冬季制熱循環，系統內制冷劑按虛線的箭頭所標方向流動。制冷劑方向的改變是由四通換向閥控制的。風冷冷凝器由軸流式風扇進行冷卻，夏季為放熱，冬季則相反。板式換熱器夏季由制冷劑蒸發而變冷,其冷凍水由水泵抽送至室內的風機盤管，由風機盤管內的離心式風扇向室內吹冷風。冬季則相反，板式換熱器變為加熱器，熱水由水泵抽送至室內的風機盤管，由風機盤管內的離心式風扇向室內吹熱風。系統中的高低壓開關起到壓力保護作用，當壓力過高或過低時，壓力開關動作，將壓縮機電路斷開保護壓縮機不致損壞。氣液分離器的作用是使液態制冷劑和氣態制冷劑分離以避免壓縮機發生液擊（濕沖程）。 

  二、對於風冷冷水機安全使用(yong)的(de)(de)致冷(leng)劑問題，有一件(jian)時盡很有可能用(yong)對條件(jian)的(de)(de)影響小的(de)(de)致冷(leng)劑，如R134a、R407C等，里面(mian)應甄選R407C，再(zai)就是是R134a；從致冷(leng)劑價充分(fen)考慮，近(jin)些年最(zui)價格低的(de)(de)是R22.
