The environmental performance of air conditioning cooling source comparison

Shape,[link widoczny dla zalogowanych], the triangle is the dividing line between two colors of two comprehensive environmental impact of ICP contours (Figure 2), weight taken in this line,[link widoczny dla zalogowanych], the comprehensive evaluation of the two programs are equal (contour can not), deviation from this will be beneficial to the contour of the comprehensive evaluation of the results of a particular program. Since the contour of the ICP by two indicators determine the classification of environmental impact, and therefore the size and contours on both sides of the program can determine the merits of the probability weights can also be used to determine the rationality of choice. Figure 2 shows: the power structure in the CH1999, the environmental impact of the centrifuge group small size of the area is less than the weight of natural gas direct-fired machine, so in our current power structure, the natural gas directly integrated environmental performance of gas turbine is superior to centrifugal unit, should be further developed. When the Three Gorges hydropower fully operational, that is, the power structure in the CH2010, the life cycle of the centrifuge group and environmental performance will be quite direct burning of natural gas (shown in black and white are almost equal.) However, the power structure in the US1999, the life cycle of the centrifuge group integrated environmental performance is better than natural gas direct-fired machine. Table 6 Air Conditioning comprehensive evaluation of the results of the cold source . wnnmel scraping ∞ o 'hearing -0 ;;;;;;;;; Figure 2 scenarios with different power groups, and natural gas direct-fired machine centrifuge comprehensive evaluation of the weight of the triangle (1) to establish a list of models to analyze the source of cold air life cycle energy efficiency, life cycle greenhouse gas emissions and life cycle SO and other major pollutants. (2) The air conditioning cold source of life cycle assessment method, and use the weight triangle explain the evaluation results to improve the evaluation of the transparency. ( 3) direct burning significantly lower life cycle energy efficiency electric drive unit, but the life-cycle gas turbine direct discharge of major pollutants was significantly lower than the electric drive unit,[link widoczny dla zalogowanych], in addition, direct gas turbine life cycle greenhouse gas emissions than electric drive is not How much of the superiority of the unit. (4) all of the Three Gorges hydropower production, the electric drive unit will enable the life cycle of energy efficiency compared to 1999 increased 15.4%, c02 emissions by 13.3%, SO, and other major pollutants emission reduction 13.2%,[link widoczny dla zalogowanych], the U.S. electric drive unit 1999, the life cycle of energy efficiency than the 1999 high of 24.8%, c02 emissions than 25.3%, SOx and other major pollutants by 32.7% less. namely: the Three Gorges hydropower will the cold source of air-conditioned environment for the life cycle of a greater degree of performance improvement, and the United States compared to the 1999 level is still a big gap. (5) in China under the current power structure, the source of the life cycle of air conditioning cooling sort of integrated environmental performance of high to low is: screw unit, natural gas direct-fired machine, centrifuge group, diesel direct gas turbine, air-cooled double-effect heat pump and steam smell lithium unit. (6) the power structure of the centrifuge environment group performance impact, but little effect on the natural gas direct-fired machine. So natural gas direct-fired machine and compare the environmental performance of the centrifuge group should consider the impact of power structure in the power structure of 1999,[link widoczny dla zalogowanych], natural gas direct superior environmental performance of gas turbine centrifuge group, the power structure of 2010, both environmental performance equivalent to the power structure in the United States in 1999 under the direct burning of natural gas centrifuge group than the poor environmental performance.
