客户解释给我听的，不懂也！Heat recovery ventilation, also known as HRV, mechanical ventilation heat recovery, or MVHR, is an energy recovery ventilation system using equipment known as a heat recovery ventilator, heat exchanger, air exchanger, or air-to-air heat exchanger which employs a counter-flow heat exchanger (countercurrent heat exchange) between the inbound and outbound air flow.[1] HRV provides fresh air and improved climate control, while also saving energy by reducing heating (and cooling) requirements.Energy recovery ventilators (ERVs) are closely related, however ERVs also transfer the humidity level of the exhaust air to the intake air.

热回收通风-即HRV,又指机械通风热回收-即MVHR, 是一种利用热回收装置，热交换器，空气交换器，或空对空热交换器来把进出空气进行逆流交换的热能回收通风系统。
HRV提供更新鲜的空气也提高了温度控制的便利，同时更能减少因制热制冷需求所需消耗的能量。
全热回收通风器（ERV），和HRV差不多原理，但ERV可转化排出和吸入空气的湿度。
