A vehicle cabin negative pressure isolation system comprises a high-pressure air curtain air supply subsystem and a negative pressure air collection and exhaust subsystem. The high-pressure air curtain air supply subsystem can be arranged in a cabin ceiling and comprises a high-pressure air curtain air supply pipeline, a high-pressure air curtain air supply port and a booster fan. One side of the high-pressure air curtain air supply pipeline is connected to a main air supply pipeline of the vehicle air distribution system, the high-pressure air curtain air supply port is formed in the other side of the high-pressure air curtain air supply pipeline, and air flow sent out forms an air curtain from top to bottom so as to form an isolation area; the negative-pressure air collection and exhaust subsystem can be arranged below a cabin floor and comprises a negative-pressure air collection tank, an exhaust pipeline, an exhaust port and an exhaust valve, one side of the exhaust pipeline is connected to the negative-pressure air collection tank, and the other side of the exhaust pipeline is connected to the exhaust valve; the exhaust outlet is formed in the top of the negative-pressure gas collection tank; and the negative pressure gas collection tank is arranged on a region corresponding to the gas curtain isolation region. By means of the system, an air curtain isolation area can be formed to reduce the infection risk, and the system can be connected with an original ventilation system to achieve conversion under different conditions of epidemic prevention.
一种交通工具座舱负压隔离系统,包括高压气幕送风子系统和负压集气排风子系统;高压气幕送风子系统可设于座舱天花板中,包括高压气幕送风管路、高压气幕供气口以及增压风机;高压气幕送风管路一侧连接于交通工具空气分配系统的主送风管路,高压气幕供气口设于高压气幕送风管路的另一侧,所送出的气流形成自上而下的气幕以形成一隔离区;负压集气排风子系统可设于座舱地板下方,包括负压集气箱、排风管路、排风口、排气门,排风管路一侧连接于负压集气箱,另一侧连接于排气门;排风口设于负压集气箱的顶部;负压集气箱设于气幕隔离区对应的区域上。藉由该系统,可形成气幕隔离区以降低传染风险,且可与原有通风系统连接,实现在平疫不同情况下的转换。
