Stratificated air conditioning system design for a large space workshop;

Analyses heat source characteristics and air d istribution design in the large space workshop and presents design of the strati fied air conditioning system.

Presents a stratificated air conditioning system with single duct and low velocity air supply in the large workshop of an 18 m span, gives its main design indices, air distribution, temperature and humidity control, air treatment and exhaustion, etc.

Thermal environment and air quality in workplacein cigarette factory;

Strong odor is produced in the process of cutting,making and packaging cigarettes as well as in the flavors kitchen at a cigarette factory in Yunnan,which contains a great deal of organic high molecule hydrocarbon,little organic low molecule hydrocarbon,and trace ammonia.

The paper introduces the security and protection sys- tem of a cigarette factory briefly, and gives the particular appli- cation method of video monitor system, inbreak alarming system, access control system, parking management system and electro- guard tour system in the cigarette industry.

Fire alarming system design in tobacco factory;

With a huge supply air and long running time, the energy consumption of central air-conditioning system of tobacco factory is much more than other central air-conditioning system.

With more sixty years development,It is necessary to improve performance evaluation system of the HY cigarette factory according to environment greatly changing.
