Abstract


Outdoor air parameters HVAC industry load calculation, equipment selection, basic design parameters. Due to the heating, ventilation and air conditioning design \According to specification provisions statistics, this parameter is used from 1951 to 1980, the basis of meteorological data. The latter part of the last century, the trend of global warming enhanced ambient temperature changes will inevitably lead to corresponding changes of the outdoor air parameters, therefore, the design parameters of the update is an essential and must work. However, the update of the design parameters should not only value updates for the status quo of China's determination method and does not guarantee international rate differences, the design parameters of the update should also include a discussion of the method for determining. This article from the outdoor air parameters determine the starting two methods and data update, mainly to complete the following contents: 1. GBJ three versions of the HVAC industry in China, the National Design Specification-TJ 19-75 19-87 GB50019- parameter part of the 2003 outdoor air calculated contrast, analysis of their similarities and differences, and explain its meaning. Parameter determines the method described in detail. ASHRAE, Japan, the United Kingdom, the outdoor air, and compare our method to compare domestic and foreign calculated parameters without guaranteed rate, different amount of information, the accuracy of the raw data, statistical year Office. Different statistical methods winter ventilation outdoor temperature organize calculated by comparison with the results with the specification of the 1951 to 1980 data calculated GBJ19-87 to determine the the winter outdoor ventilation temperature data statistical methods. 4 to 29 cities including Beijing, Guangzhou, Harbin, January 1, 1978 to 31 December 2007, the purpose of each mesh 4 timing temperature value and relative humidity data by our method and abroad is not guaranteed rate finishing the last 10 years, 15 years, 20 years and 30 years of outdoor air parameters, and by comparison of the results obtained are more suitable for our current statistical life and determine. 5. GBJ19-87 data with the results of this paper is based, to calculate the temperature of the heat load of the winter heating and summer cooling load calculation of the amount of change.
