正在犹豫是否装 Heat Recovery Ventilator (HRV) ？新房子。

请给点建议 。 谢谢！

那东西当然好，不光是节能，更能改善室内空气质量。

现在的房子讲究Air Tight。这样是节能了，但冬天屋里换气很差。记得有文章说过，七十年代的房每天的换气量是房子容积的三倍以上，现在的房子只有不到一倍。

除换气量小以外，室内负压也对空气质量有影响。装了大号抽油烟机的房子，更容易出现负压。有了ＨＲＶ以后，室内会稍稍有些正压力，建筑材料挥发出的气体和地下的气体都不会往屋里走。

只是不知道在盖新房的时候装ＨＲＶ要多加多少钱？

Yes you can. You may want to check with local HVAC contractors before making final decision.

Home Depot's installation fee is $800

The total cost will be more than $1500.

I think HRV is included in all the Energy Star package, and my builder Tartan charges me $1,500 for that HRV as well..

Dumb question, too lazy to google: is an HRV same as a hot air exchanger?

Yes 渐渐. "Heat Recovery Ventilation System" is A.K.A. "Air to Air Heat Exchangers"
