[#10] 中央冷氣系統會傳染武漢肺炎嗎?    
首先要搞清楚何謂"中央空調係統"先! 如果講容易播毒,中央系統未必會容易過獨立系統。

[#11] 中央冷氣系統會傳染武漢肺炎嗎?    
A central centrifugal plant (usually variable speed now) with chiller water(no longer AHU, air handling unit, only for small area) and fan coil to bring cool air to commercial building partitioned areas, the concern is mixing up of the return air(hence, breath) from many occupants. The "retired soldier syndrome" is spread by A/C except contaminated cooling tower using fresh water.(common for industrial building, a large conical tank hanging outside building) Bacteria gets into the cool air.(chance is via fresh air intake of the system since refrigerant side is a closed system)
