How it works

The concept of energy recovery (ERV) can be traced back to the 20th century. A Britain, Alston Ceeyee used the method exhausting indoor air and introduce fresh air to the room to form an orthogonal cross ventilation. This method can

retain the temperature and humidity lost due to ventilation, while still able to supplement fresh air with nearest indoor temperature through this device under a confined room.

Therefore, it can reduce the load of air conditioning and achieve the purpose of ventilation and electricity saving.

ERV mainly consists of five components, which are the duct interface, multi-wing turbine blades, filters, motor, and heat exchange. The heat exchanger is responsible for exchanging temperature and humidity between indoor polluted air and outdoor fresh air.

Heat exchanger is composed of multi-layer films. The films completely separate the supply air and exhaust air space. When the air passes through the film, due to the temperature difference and steam pressure difference on both sides, heat transfer occurs between the two airflows, to exchange temperature and humidity.
