<title>You are RIGHT!</title>
<content:encoded><![CDATA[<p><em>Reply by 匿名, Tuesday, February 02, 2016, 19:59:</em></p><p><p>The energy cost of exhaust-only or natural ventilation versus energy recovery ventilation can be easily demonstrated. Take a 2,500-square-foot house with indoor conditions of 70°F and 40% relative humidity, and outside air conditions of 30°F and 50% relative humidity. If we ventilate the house with 120 cubic feet per minute (prevailing wisdom of 0.35 air changes per hour) of outside air (as compared to no fresh air at all), here is how much the ventilation will cost us per month. This is due to the additional heating energy required because of the ventilation.</p>
<p>120 ft.3/min. × 60 min./hr. × (25.3 Btu/lb. – 9.06 Btu/lb.)* × 0.074 lbs./ft.3 × 1.25 efficiency × 24 hrs./day × 30 days/mo. × (1 × 105 therms/Btu) × $1.50/therm = $116/mo.<br />
*Enthalpy of indoor vs. outdoor air (see psychrometric chart)</p>

<title>这个能耗不算电加热的，那是个option. 加热交给furnace，但有了热交换，可以回收一部分热量，所以可以减轻furnace负担．其实它的原理就是这么简单．</title>

<title>如果你的baseline是冬天室内不需要新鲜空气，那当然没有必要装。还是那句话，生活品质不同。</title>

<title>怎么能节省能源？尤其在冬天。这个热交换还要加热冷空气。不是白白浪费能源么。难道装了这个系统反而省？</title>

<title>冬天冷空气进来，怎么加热？这个能耗是算在这个系统中还是加重Furnace的负担？</title>

<title>撇开energy saving和cost不说，其实就是一个提高生活质量的问题。每天开窗可以，但需要开多长时间？室内空气也不均匀？如果开窗时，开furnace的循环，一样耗电。</title>

<title>HRV system 74% energy savings of the ventilation loss, amounted about 30 kWh.m-2 per year. Investment would payback during 12 years.</title>
