Description

Technical Field

[0001] The present invention relates to the technical field of building ventilation, and particularly to an intelligent temperature-controlled building exterior wall ventilation device. Background Art

[0002] Building ventilation is divided into natural ventilation and mechanical ventilation, which means that the polluted air indoors in a building is directly or purified and then discharged outdoors, and then fresh air is supplemented to keep the indoor air environment meet the hygiene standards. Its purposes are: ① to ensure the removal of indoor pollutants; ② to ensure the thermal comfort of indoor personnel; ③ to meet the need of indoor personnel for fresh air.

[0003] First, use the fresh air outdoors to update the air polluted indoors due to residence and life processes to keep the cleanliness of the indoor air reach a certain minimum standard level. Such requirements can be called healthy ventilation, which should be ensured under any climate conditions. Secondly, increase heat dissipation in the body to prevent discomfort caused by skin moisture to improve comfort conditions. Such ventilation can be called comfort ventilation. Thirdly, when the indoor temperature is higher than the outdoor temperature, cool down the building. Such is called the cooling ventilation of the building.

[0004] Provide the necessary amount of oxygen for the main living activities of residents, such as breathing and cooking, and prevent excessive carbon dioxide and unpleasant odors. Due to people's breathing, the indoor air will be polluted anyway. Therefore, ventilation is needed to replace fresh air. It is estimated that an adult needs about 30 cubic meters of fresh air per hour. Therefore, the number of people indoors is particularly important. Yagro et al. gave the ventilation efficiency, that is, the ratio of the effective air flow in the entire usable area to the entire air supply volume.

[0005] There is a great relationship between temperature and indoor odor. When the indoor temperature is 18°C, people have no uncomfortable feeling about the odor. Then, each person in the room needs 30 cubic meters of fresh air per hour. When the indoor temperature rises to 30°C, if people are to have no uncomfortable feeling about the odor, each person in the room needs 50 cubic meters of fresh air per hour. For kitchen ventilation, there is a heat balance method, which determines the ventilation rate according to the cold loads of kitchen utensils, people, lamps and building envelopes and the indoor and outdoor temperatures, and determines the ventilation rate according to the size of the kitchen and the size of the exhaust air volume.

[0006] The exhaust air volume of natural ventilation is affected by factors such as indoor and outdoor temperature, humidity, atmospheric pressure, wind direction and wind speed. The exhaust air capacity is small and the exhaust air volume is very unstable. Sometimes the exhaust air outlet is in a positive pressure state and backflow occurs. However, it is currently impossible in China to achieve mechanical exhaust for all covers. For living rooms and offices, natural ventilation is advisable, and outdoor cold air infiltration is used in cold regions to compensate for fresh air.

[0007] Traditional building exterior wall ventilation devices usually adopt fixed ventilation openings or manually adjustable louvers, which cannot automatically adjust the ventilation volume according to the changes in indoor and outdoor temperatures and air quality. This not only causes energy waste but also may lead to a decline in the indoor environmental quality. However, in this solution, xx. Therefore, an intelligent temperature-controlled building exterior wall ventilation device is needed to improve the above problems. Summary of the Invention
