Study On The Scheme Select On Method Of Theair-Conditioner Heat And Cool Souroes

The scheme selection method for the air-conditioner heat and cool source is animportant decision-making stage during the designing of air-conditioning systemwhich relates to important problems about investment project, fee of operation,affection of environment, consumption of energy, which is also an important factoraffecting the general society energy consumption and project investment. How tosuccessfully and rationally select the optimized model scheme for the air-conditionerheat and cool source based on the practical conditions of projects has become thefocus of the project designers and users.This thesis tries to study option methods of air-conditioner heat and cool sourceand finds a scientific, rational and simple decisive way in order to raise the decisivelevel, improve the quality of designs and reach the best effect of the scheme optionfor the theoretical instruction supplied for project technicians to select air-conditionerheat and cool source.Based on the detailed analysis of the various air-conditioner heat and cool sourceequipments, twenty-three methods of the selection schemes are presented byweighing the equipments'advantages & disadvantage, energy consumption and realconditions. After the unfeasible schemes being wiped out, the candidate schemesfitting for the building are selected combined with a practical case. Through theoption of the selection method for the schemes of the air-conditioner heat and coolsource, the analytical hierarchy process(AHP)method is the decisive one for itssimple and practical merit.The schemes are selected by using AHP to the practical cases and thecomparison between the AHP decisive result and real project is very closed byestablishing the evaluation index for fitting scheme selections of the air-conditionerheat and cool source, using the huge capacity of calculating by Excel and turningmatrix into table form , which indicates AHP & Excel calculating is the simple andpractical decisive method for fitting scheme selection of heat and cool sources.
