小百兔,看看這個

別去折騰那個壞的.不容易找到控製線,FREON進出口徑都MATCH的室內機. 室內機的EVAPORATOR容量也必須MATCH.

室內機一拆,FREON全跑了,還得重灌. the hassle/time/money is more than buying a new one.

consider buying a "PORTABLE" AC. it sits on the floor inside the room. It has a hose that goes through window (or a hole in the wall) to exhaust hot air. very easy to install - you do it yourself. slide the window for a crack. get a piece of foam plastic to fit the hose in the crack. works instantly. only downside is that the water pan needs to be emptied every day or two.
