The heat recovery ventilator (HRV) is the proper choice in colder climates where there is excess humidity during the heating season, since it can eliminate it.# z* w" V y5 S$ w( K$ C. D3 ^
The HRV keeps the home supplied with a steady flow of fresh outdoor air. As stale, warm air is expelled, the heat recovery core warms the incoming fresh, colder air before it is distributed throughout the home. % H; T0 A$ G4 }4 H; C; q( j* f1 D$ kThe result is a constant supply of fresh air, no unpleasant drafts and greater home comfort. 2 x- m; t# |9 e1 ]9 n- r; k
其实这里房子冬天室内湿度都很低,一般在30左右,不存在湿度过高的问题。主要问题是窗户保温不好。外面温度很低时,室内窗户还会结冰。我的解决办法是:remove inside sidings for all windows and doors, redo undulations and seals; in summer time re seal out side frames for all windows and doors. Then increase the temperature inside. It helps a lot. But the best way is to replace with new windows and doors with good insulation. Add more insulation for the house if necessary.
