Description

Two-way ventilation energy-saving window

technical field

The invention relates to a ventilation energy-saving window.

Background technique

The construction industry consumes huge natural resources and social wealth. The total energy consumption of buildings in China is increasing year by year, and its proportion in the total energy consumption has risen from 10% in the late 1970s to 27.45% in recent years. Heating and air conditioning energy consumption accounts for 55% of the total building energy consumption. The indoor environment is one of the most frequent and intimate external environments that people come into contact with. People spend more than 80% of their time indoors. Therefore, the quality of indoor air has an extremely important impact on human health. However, improving indoor air quality often requires a lot of energy consumption.

Under the current background of advocating energy saving and improving indoor air quality, many related technologies have emerged in the construction industry, but these technologies have different limitations and problems that need to be solved urgently. For example, the window type with good thermal insulation performance must be opened for ventilation, and natural ventilation consumes a lot of energy, which weakens its own advantages of strong airtightness and low heat transfer coefficient; the double-layer heat channel glass curtain wall is expensive and requires the building to be multi-storey Or high-rise buildings, which cannot be widely used in residential buildings; airflow window technology, which can improve indoor air quality or realize heat recovery to reduce energy consumption, or have the advantages of ventilation and heat exchange. However, this technology has limitations. Some are single-channel airflow windows, which only have a single function of sending outdoor fresh air into the room or exhausting indoor air to the outside, and the energy-saving effect is not ideal; some are dual-channel airflow windows. The dual functions of fresh air and indoor dirty air removal, air supply and exhaust can be exchanged through the middle layer, which has a good energy-saving effect, but this airflow window technology has the following problems: the use of electric fans, namely axial flow fans, to provide ventilation The power is limited by the performance of the axial flow fan. If the axial flow fan sucks or blows air axially, the tuyere cannot be directly aligned with the airflow cavity, and the size of the fan cannot match the size of the ventilation cavity, which will affect the uniformity of the airflow organization during the air supply and exhaust process; after installing the axial flow aircraft, The cross-counterflow heat exchange is formed in the window, the heat exchange area is small, and it is easy to form a dead angle in the air duct, the heat exchange is not sufficient, and the heat exchange efficiency is low; the axial flow fan is noisy, which weakens the sound insulation and noise reduction performance of the airflow window ; The flow rate of the axial flow fan is not easy to adjust, the working pressure head changes drastically with the flow rate, and the starting power is large, so a motor with a larger power is required.
