Small birds and mammals commonly minimize respiratory heat loss with reciprocating counterflow exchangers in their nasal passageways. These animals extract heat from the air in an exhalation to warm those passageways and then use that heat to warm the subsequent inhalation. Although the near-constant volume of buildings precludes direct application of the device, a pair of such exchangers located remotely from each other circumvents that problem. A very simple and crudely constructed small-scale physical model of the device worked well enough as a heat conserver to suggest utility as a ventilator for buildings.
小型鸟类和哺乳动物通常在鼻腔通道中使用往复逆流交换器来最小化呼吸热损失。这些动物在呼气时从空气中提取热量，以温暖这些通道，然后利用这些热量来温暖随后的吸入空气。尽管建筑物的容积几乎保持不变，使得该设备无法直接应用，但在彼此远离的位置上设置一对这样的交换器可以解决这个问题。该设备的一个非常简单和粗糙的小规模物理模型作为热储存器的效果非常好，这表明它可以作为建筑物的通风设备使用。
