热回收通风（HRV）技术用于满足室内空气质量要求，同时降低建筑能耗。在典型的安装中，HRV系统预计将减少能源需求;然而，实际效益取决于机械系统，气候条件和建筑设计。在这里，我们评估的能源节约显热回收在加拿大各地的住宅公寓建筑物的建筑热需求和暖通空调系统的能源使用建模。我们比较了一个商业的空气-空气热泵耦合到一个平衡的通风系统，有和没有HRV的年度性能。一个假设的住宅套房是根据加拿大十五个城市的八个不同的建筑方向建模的。结果表明，HRV的使用总是减少全年的供暖能耗，但在冷却季节，能源消耗可能会增加。
Heat recovery ventilation (HRV) technologies are used to satisfy indoor air quality requirements while reducing building energy consumption. In a typical installation, an HRV system is expected to decrease energy demand; however, the actual benefit depends on the mechanical system, climate conditions, and building design. Here, we assess the energy savings from sensible heat recovery in residential apartment buildings across Canada by modeling the building thermal demands and the HVAC systems energy use. We compare the annual performance of a commercial air-to-air heat pump coupled to a balanced ventilation system with and without the HRV. A hypothetical residential suite is modeled under eight different building orientations for fifteen Canadian cities. Results show that HRV use always reduces the annual heating energy consumption; however, energy consumption may increase in cooling seasons.
