| Summary: | A method for calculating refrigerating machines with a condensation unit implementing water and air
cooling methods is proposed taking into account the economic and climatic features of the calculated
region. Since economic and climatic factors have different degrees of influence on the energy efficiency
and efficiency of refrigerating machines over the entire range of changing temperatures of cooling
media, the results of calculating refrigerating machines according to the proposed methodology allow
making informed decisions about the layout of the condensation unit both at the design stage and at the
stage of developing a program for managing the refrigeration unit throughout the year. A comparative
analysis of refrigerating machines with combined cooling of condensers for the regions of Omsk and
Berlin is carried out. The most significant influence of the climatic factor at low temperatures of the
cooling air and the influence of the cost of cooling water at high air temperatures were revealed. |
