System for switching from non-negative pressure space to negative pressure space

摘要

The present invention relates to a system capable of quickly converting a non-negative pressure space into a negative pressure space when a large number of negative pressure spaces are required due to the outbreak of a large-scale infectious disease. A window system 20 with a standardized hole is installed on the window of the non-negative pressure space, and then closed with a cover in normal times. In case of emergency, the hole is opened and a negative pressure generator is installed to discharge the air from which the pollutant has been removed to the outside, thereby urgently releasing the negative pressure in the space. can be converted into space. The present invention has the effect of quickly securing a large number of sound pressure spaces at a low cost.
