Ecological Systems and Devices Annotation << Back IMPROVEMENT OF ECOLOGICAL AND POWER CHARACTERISTICS OF AIR HEAT EXCHANGERS O.V. Kryukov Ways of improvement of processes of cooling of gaseous products in air coolers by optimization of mechanical, aerodynamic and heat technical constructs are considered and also new structures and control algorithms of electric drives of fans methods of decrease in operational expenses, due to reduction of a power component by optimization of distribution of loading of several heat exchangers are offered. Need of use of the frequency and adjustable electric drive of fans at change of parameters of air is proved. Keywords: air coolers; optimization; ecological and power characteristics; fan; electric drive. DOI: 10.25791/esip.11.2018.252 Contacts: E-mail: o.kryukov@ggc.nnov.ru Pp. 14-22.
