Description

Technical Field

[0001] The utility model relates to the technical field of indoor ventilation effect detection, in particular to a portable indoor ventilation effect detection device. Background Art

[0002] During the indoor ventilation effect detection process, the wind speed sensor can measure the speed of air flow in real time, thereby calculating the air flow rate. These data can be further used to calculate parameters such as ventilation volume and static pressure loss. By comparing the wind speed and air volume at two cross-sections of the duct, the duct pressure loss can be calculated more accurately, and the performance of the system in actual operation can be understood. The wind speed sensor is small and light, easy to carry and assemble.

[0003] During the wind speed measurement process, the multiple wind cups on the wind speed sensor are exposed to the external environment and are easily affected by external factors. For example, dust and particles adhere to the surface of the wind cups, increasing the friction resistance of the wind cups. At the same time, excessive wind speed and temperature will cause excessive impact on the wind cups, causing wear and damage to the wind cups. The wind speed sensor is designed with an integral structure. If one of the multiple wind cups is damaged, it needs to be replaced as a whole, which causes a waste of resources and reduces the utilization rate of the wind speed sensor.

[0004] Therefore, a portable indoor ventilation effect detection device is urgently needed to solve the above problems. Utility Model Content
