Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning parts, in particular to a wind pressure regulating device for a ship air-conditioning pipeline. Background Art

[0002] Wind pressure (wind pressure) Due to the obstruction of buildings, the surrounding air is blocked, the dynamic pressure decreases, and the static pressure increases. Local vortices are generated on the sides and back, the static pressure decreases, and the dynamic pressure increases. Compared with the undisturbed airflow in the distance, this increase and decrease in static pressure is collectively referred to as wind pressure. The concept of wind pressure Wind pressure refers to the pressure generated by the resistance of airflow during gas transportation. It is usually used to describe the working performance of gas transportation machinery (such as fans) during operation. Wind pressure can be divided into dynamic wind pressure and static wind pressure. Dynamic wind pressure is the pressure generated by the movement of airflow, which is mainly related to the flow rate and air density of the air flow. The calculation formula of dynamic wind pressure is: wp = 0.5*ρ*v^2, where wp represents dynamic wind pressure, ρ represents air density, and v represents airflow velocity. Static wind pressure is the pressure generated by the gas under the action of gravity, which is mainly related to air density and height. The calculation formula of static wind pressure is: gh = ρ*g*h, where gh represents static wind pressure, ρ represents air density, g represents gravity acceleration, and h represents height. In practical applications, wind pressure is usually used to measure the performance of gas conveying equipment such as fans. The greater the wind pressure, the stronger the air flow conveying capacity. However, in actual projects, other factors such as air volume, noise, energy consumption, etc. need to be considered to comprehensively evaluate the effect of gas conveying equipment.

[0003] The application number is CN202321902121.6, which discloses a wind tunnel wind pressure regulating device, including a boosting section, a rectifying section, a heating section and a frame arranged at the bottom of the shell, which are connected in sequence. The boosting section is composed of an active air inlet, a passive air inlet, a sealing spacer and a transition piece. The active air inlet is arranged at one side of the bottom of the shell, and the active air inlet is used to provide gaseous fluid (wind) power. The passive air inlet is arranged on one side of the shell adjacent to the active air inlet. The sealing spacer is connected to the active air inlet, and the sealing spacer is used to seal between the two parts to prevent leakage to the outside. The transition piece connects the sealing spacer, the passive air inlet and the active air inlet, and the transition piece is used to transmit the gaseous fluid (wind) to the subsequent transmission. A driven pressure diffuser ring is arranged at the passive air inlet, and an upturned trumpet is formed between the driven pressure diffuser ring and the transition piece. The utility model belongs to the technical field of wind tunnel test supporting equipment, and specifically provides a wind tunnel wind pressure regulating device with the function of enhancing wind pressure.
