Description

A kind of ventilation vent device for building equipment room

technical field

The utility model belongs to the technical field of ventilation and air conditioning, relates to the improvement of air vents in ventilation and air conditioning rooms, and in particular relates to a ventilation vent device used in a building equipment room.

Background technique

With the development of economy, the construction industry is still in the stage of rapid development. With the improvement of people's living standards, more and more equipment is equipped in buildings, including generator rooms, air-conditioning equipment rooms, and network rooms. Due to the needs of people's lives, these equipment rooms are basically operated all year round, which leads to an increase in the ambient temperature in the rooms. The main reason for the increase in the ambient temperature around the device is the accumulation of a large amount of heat in the room. However, there is no equipment for rapid heat extraction in the equipment room, resulting in the heat generated by the air constantly gathering and heating up in the environment. If the ventilation and ventilation of the building equipment room cannot be solved properly and the air flow inside and outside the room can be accelerated, the service life and work efficiency of the equipment will be greatly reduced, the wear and tear of the equipment will be accelerated, and even equipment failures will be frequently caused. Therefore, among the factors that affect the operation effect of equipment in the equipment room in the short or long term, the research on the ventilation and ventilation openings in the equipment room of construction equipment is particularly worthy of attention.

By rationally arranging ventilation openings in the building equipment room, the air jets of the ventilation openings are used to realize the mixing of supply air and indoor air, so as to achieve the purpose of ventilation and adjustment of indoor air temperature and humidity. As one of the most widely used tuyere forms, the diffuser has uniform dispersion characteristics and a simple and beautiful appearance. In the current engineering practice, the common diffuser has only one set of ordinary air outlets, and the air outlet direction is single. In order to achieve the air supply effect in the equipment room of the construction equipment, multiple air supply ports are usually arranged symmetrically in the equipment room to improve the accessibility and uniformity of the air supply of the air conditioner in the equipment room. However, arranging multiple air outlets will make the layout of air ducts in the building complicated, the initial investment of the project will increase, and the energy consumption will increase. Therefore, if the structure of the diffuser can be optimized, so that one air outlet can be used instead of multiple air outlets in the construction equipment room, which can not only reduce energy waste, but also significantly improve the ventilation in the construction equipment room.

It can be seen that the study of a ventilation vent device for the building equipment room plays an important role in improving the airflow organization and energy saving in the building equipment room.
