The fresh air system is a common air treatment equipment in modern homes and commercial buildings, which can provide a continuous supply of fresh air and discharge indoor polluted air. In the fresh air system, heat recovery efficiency is a key indicator, and high heat recovery efficiency means that the system can more effectively recover energy during the ventilation process, thereby reducing energy consumption. Total heat exchange technology can recover heat and humidity while ventilating, reducing energy loss caused by ventilation and achieving energy conservation and consumption reduction.

Total heat recovery refers to the process in which a fresh air system, while introducing fresh outdoor air, recovers the heat and humidity from the discharged indoor air through a heat exchanger for heating or cooling the incoming fresh air. A total heat exchanger is an energy-saving device in a fresh air system that can exchange heat and humidity without mixing fresh air and exhaust air.
The application of total heat exchange technology not only reduces reliance on air conditioning and heating equipment, but also lowers overall energy consumption, in line with the concept of sustainable development. Choosing a suitable fresh air system can not only improve living comfort, but also achieve the goals of energy conservation, emission reduction, and carbon neutrality.
