With the development of economy, the construction industry is still in a rapid development stage. Along with the improvement of the living standard of people, more and more equipment are equipped in the building, and common equipment comprises a generator room, an air conditioning equipment room, a network room and the like. Due to the living needs of people, these equipment rooms run essentially throughout the year, thereby causing an increase in the ambient temperature in the room. The main reason for the increased temperature of the environment surrounding the device is that a large amount of heat is accumulated in the room. And the heat air generated by the fact that no equipment for rapidly pumping and exhausting the heat is arranged in the machine room is continuously accumulated and heated in the environment. If the ventilation of the building equipment room can not be well solved, the indoor and outdoor air flow is quickened, the service life and the working efficiency of equipment are greatly reduced, the abrasion of the equipment is quickened, and even the equipment is frequently caused to be failed. Thus, the study of ventilation opening devices in a building equipment room is particularly interesting among the factors that affect the operation of the equipment in the room in short or long term.
Through reasonable arrangement of ventilation ports in a building equipment room, air jet flow of the ventilation ports is utilized to realize the mixing of air supply and indoor air, so that the purposes of ventilation and indoor air temperature and humidity regulation are achieved. The diffuser is one of the most widely used tuyere types, and has uniform diffusing characteristics and a compact and attractive appearance. In the current engineering practice, the common air diffuser has only one group of common air outlets, and the air outlet direction is single. In order to realize the air supply effect in the machine room of the building equipment, a plurality of air supply openings are symmetrically arranged in the machine room, so that the air supply accessibility and uniformity of air supply of the air conditioner in the machine room are improved. However, arranging a plurality of tuyeres can complicate the arrangement of air pipes in a building, increase the initial investment of engineering and increase the energy consumption. Therefore, if the structure of the diffuser can be optimized, one air port is used for replacing a plurality of air ports in the building equipment room, so that the energy waste can be reduced, and the ventilation in the building equipment room can be obviously improved.
It is seen that the ventilation and ventilation port device for the building equipment room has important effects on improving the airflow organization and saving energy in the building equipment room.
