Indoor secondary gas flow equipment used for large-space large-span building

Abstract

The invention discloses an indoor secondary airflow device used in large-space and large-span buildings and is characterized in that an air inlet is arranged on one lateral wall or the bottom of a case, an air outlet is arranged on the other lateral wall of the case, the air inlet is communicated with an air inlet chamber that is communicated with a fan entrance, and a fan air outlet is sequentially connected with a guide chamber, an air outlet section and the air outlet; a guide plate 1 is connected on an inner wall under the fan air outlet and divides the guide chamber into an upper cavity and a lower cavity that are communicated, a guide plate 2 is arranged between the lower cavity and the air outlet section, and the lower cavity is communicated with the air outlet section and the air outlet. A flashboard is arranged on the lateral wall of the air outlet and connected with a guide plate 3 by two arc skid shoes. An advertising lamp box is arranged on the lateral wall of the case. The secondary airflow device of the invention has the effects of transferring primary air feeding energy and separating upper and lower regions with and without an air conditioner, thus leading the environment of the lower air conditioner region to be uniform and comfortable.

Description

technical field [0001] The invention relates to an indoor secondary airflow device used in large-space and long-span buildings. It is used in the air-conditioning area where the air-conditioning air supply is difficult to reach, and improves the thermal environment of the air-conditioning area. Background technique [0002] At present, the indoor environment design of large-space buildings is mostly used as the goal of comfort, such as exhibition hall buildings, gymnasiums, theaters, atriums, etc. In such large-space buildings, the indoor personnel activity area is low, and the energy consumption of air-conditioning in winter and summer is high. Therefore, this type of large-space buildings Spatial buildings usually adopt layered air-conditioning, and some air-flow organizations such as bag air supply and down-flow air supply are used to form air conditioning within a limited height and reduce air conditioning energy consumption. [0003] When the indoor span of a large spa...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a secondary airflow device for large-space and long-span buildings. The device can be installed within the range of the indoor nozzle air supply range, and can also be installed in places where the air supply is difficult to reach. Its purpose is to overcome the existing nozzle air supply technology It cannot meet the needs of large-span buildings for ambient temperature and wind, and avoid human discomfort caused by uneven indoor temperature and wind speed
