The main reason is that many high-grade office space is equipped with all-air central air conditioning, is to first deal with air, reducing temperature and humidity, the air sent through the pipeline to the room through the return air, pipeline to return to the central processing system, central processing system for cooling air return after降湿part of the new wind coupled with the second round after the blast, and so the cycle, while the central air-conditioning system for energy conservation, often adding a little fresh air, return air devices in the recovery rate of 80%, resulting in cross-infection the opportunity to increase significantly.

主要的原因是，许多高品位的办公空间配备了全空气中央空调，是先处理空气，降低温度和湿度，空气通过管道传送到房间通过回风管道返回中央处理系统，中央处理系统，冷却空气降湿后返回的一部分，新风，加上第二轮爆炸后，所以周期，而中央空调系统节能，往往增加了小新鲜空气，回风装置，回收率为80 ％，导致交叉感染的机会大大增加。

The cooling system is made up of the passages inside the engine block and heads, a water pump to circulate the coolant, a thermostat to control the temperature of the coolant, a radiator to cool the coolant, a radiator cap to control the pressure in the system, and some plumbing consisting of interconnecting hoses to transfer the coolant from the engine to radiator and also to the car's heater system where hot coolant is used to warm up the vehicle's interior on a cold day.
