An energy-saving ventilation device for architectural engineering structure design

Abstract

The invention discloses an energy-saving ventilation device for architectural engineering structure design, which comprises a ventilation main body, and a displacement device and a strain device are arranged inside the ventilation body; through a locking device, a displacement device, a driving device, a clamping device, a strain device, The cooperation of the trigger device enables the energy-saving ventilation device to provide power for the shut-off device in the cold winter environment, prompting the shut-off device to produce corresponding actions, so that the ventilation main body and the shut-off device cannot form a Joule-Thomson effect system, avoiding the energy-saving The ventilation device continuously cools down the ventilation airflow in the cold winter environment, resulting in an increase in the heat load of the central air conditioner, which significantly reduces the energy consumption of the central air conditioner throughout the year, thereby significantly increasing the energy-saving effect of the energy-saving ventilation device and improving Practicality of energy-saving ventilation devices for structural design of the building project.

[0002] Building ventilation is divided into natural ventilation and mechanical ventilation. It means that the dirty air in the building is directly or purified and discharged to the outside, and then fresh air is added in, so as to keep the indoor air environment in line with hygienic standards. pollutants, ensure the thermal comfort of indoor personnel, and meet the needs of indoor personnel for fresh air. Natural ventilation is the ventilation that realizes indoor ventilation under the influence of indoor and outdoor temperature differences, density differences, and wind pressure differences. Mechanical ventilation uses ventilation machinery to achieve ventilation. In order to ensure the thermal comfort of indoor personnel, it is usually necessary to use a central air conditioner to assist heating or cooling, which consumes a lot of energy. The existing patent application number CN201920159633.5 discloses a building ventilation device, including A ventilation box outside the object, the front surface of the ventilation box is provided with an air inlet, the rear surface of the ventilation box is provided with an air outlet connected to the building room, and the ventilation box is provided with an air inlet located at the air inlet. The following mounting plate, the mounting plate and the inner wall of the ventilation box are sealed and connected, and fine holes are evenly distributed on the mounting plate, and the front side surface of the mounting plate is provided with an inlet corresponding to each of the fine holes. The air cylinder, the diameter of the air inlet cylinder is larger than the diameter of the fine hole, the rear side surface of the mounting plate is provided with a mounting ring communicating with the fine hole, and the mounting ring is provided with a plurality of intervals. The inner adjustment plate, the outer adjustment plate is arranged between the adjacent inner adjustment plates, the inner surface of the outer adjustment plate is pressed against the outer surface of the inner adjustment plate, and the adjacent outer adjustment plates are also spaced from each other , between the inner adjustment plate and the installation ring, there is an elastic connection mechanism that enables the inner adjustment plate to swing inside and outside, and between the outer adjustment plate and the installation ring, there is also an elastic connection mechanism that enables the outer adjustment plate to swing inside and outside. The elastic connection mechanism also includes a swing drive mechanism that makes the outer adjustment plate and the inner adjustment plate swing; the diameter of the air inlet tube is larger than the diameter of the fine hole, and the Joule-Thomson effect can be used to reduce the airflow of the air outlet. temperature, thereby regulating the temperature in the building

[0003] The technical scheme of the above-mentioned existing building ventilation device can only reduce the working cooling load of the central air conditioner in the hot summer environment, thereby achieving the purpose of energy saving, but has poor applicability and is not suitable for cold winter. When working in the environment, the ventilation airflow will still be cooled, which will make the indoor temperature lower than the outdoor temperature. The central air conditioner needs to generate more heat to control the indoor temperature in a comfortable atmosphere, resulting in central air conditioner failure. The heat load of the work increases significantly, and the energy consumption will also increase accordingly. Based on the use of the whole year, the energy-saving effect of the existing building ventilation device is extremely poor. Therefore, it is urgent to design an energy-saving ventilation device for structural design of construction engineering.
