Description

A high-efficiency and energy-saving fresh air ventilator

Technical Field

The utility model relates to the field of fresh air ventilators, in particular to a high-efficiency and energy-saving fresh air ventilator.

Background Art

In modern human life, most air-conditioned rooms are closed. In a closed room, due to poor ventilation and insufficient fresh air, people in the room will feel sleepy, weak, and have reduced work efficiency.

The traditional ventilation method of opening windows and installing ventilation fans causes the fresh air to carry a lot of dust, affecting indoor hygiene. When using heat sources in winter and cold sources in summer, the traditional ventilation method will cause energy waste. The air conditioning devices currently used with partial fresh air have very little outdoor fresh air supplemented, and cannot fundamentally solve the ventilation problem. Small household central air conditioners have no exhaust structure, and the dirty air cannot be quickly discharged to the outside. It is difficult to send fresh air into the positive pressure area that has been formed. Although there is a return air vent, it cannot exchange with the outdoor air. A small amount of fresh air cannot completely improve the indoor air quality.

The fresh air ventilator currently used consists of a housing, a blower, an exhaust fan, a dirty air outlet, a dirty air inlet, a fresh air inlet, a fresh air outlet, etc. It uses a static heat exchanger to recover heat, and the heat exchange efficiency is generally less than 70%, which partially solves the problem of energy waste; the fresh air entering the room is filtered and sterilized, which improves the indoor air quality. However, the low heat recovery efficiency, high price and large size have affected the promotion and application of fresh air ventilators.
