空调制冷为什么要开电辅热

1、室外温度过低 室外温度过低会造成空调无法正常工作,一般室外在零度以下,变频空调的室外在零下15度左右已经无法正常制热了,所以有可能是室外过低,空调无法化霜,空调不能制热。

2、空调四通阀漏气 四通阀,液压阀术语,是具有四个油口的控制阀。四通阀是制冷设备中不可缺少的部件,其工作原理是,当电磁阀线圈处于断电状态,先导滑阀在右侧压缩弹簧驱动下左移,高压气体进入毛细管1后进入右端活塞腔。 < 这个原因导致的<&#;# >海尔lt;&list>海尔lt;&list>海尔lt;&list>毛细管<f<list>海尔<&list>美的<&Bdenc、Kc>海尔lt;&list>海尔<<&list>美的<&list>海尔<&list>海尔<&list>海尔<&list>海尔<&list>海尔&list>海尔&list>海尔&list>海尔&list>海尔&list>海尔&list>海尔&list>海尔&list>美的&list>海尔&list>美的&list>海尔&list>海尔&list>燃气灶&list>华帝&list>海尔&list>燃气灶&list>华帝&list>华帝&list>美的&list>美的&list>海尔&list>燃气灶&list>燃气灶&list>华帝&list>燃气灶&list>燃气灶&list>华帝&list>燃气灶&list」&list>华帝&list>燃气灶&list>燃气灶&list;华帝&list>华帝&list>燃气灶&list>燃气灶&list;华帝&list>燃气灶&list>燃气灶&list>华帝&list>燃气灶&list;华帝>燃气灶&list;华帝>燃气灶&list;燃气灶&listgt;燃气灶&list。
