Evaluation of technical-economic parameters of the design decision of conditioning system

Annotation

The purpose of the article is to analyze the selections of criteria allowing evaluating options for design solutions of air conditioning and ventilation of air.In connection with a spread practice the adoption of basic technical solutions occur on based on subjective assessments, it is becoming urgent to optimize the selection of criteria , taken into account the different multi directional characteristics and features designed systems. The article provides a review of additive and multiplicative criteria.The example of specific design solutions of air conditioning the authors aim to analyze the preference use of one or another criterion. Evaluation of the considered design decisions (4 options) conducted on the basis of two parameters: the capital costs on climate equipment and electric power which consumption occur on the equipment during the year.These parameters are considered likea equally significant. Based on this analysis are compared the effectiveness and economy of selected air conditioning systems. In conclusion in the article draws conclusions and gives recommendations on the feasibility of using multiplicative or additive criteria depending on the significance of the parameters taken into account.
