Analysis of the year power consumption by central air conditioning systems (Using the climatic data stochastic statistics model)

Abstract

The purpose of offered research is creation of a method of an estimation of annual power consumption by the central systems of air-conditioning (SAC), taking into account possibility of modern computers. The developed method is directed on definition of expenses of thermal and electric energy, and water during a year by the SAC taking into account their work at various period of day and optimization of the scheme of treatment of reveal air on the basis of minimization of power inputs. On chair Heating and Ventilation MSUCE the universal program for calculation on the computer of power and water consumption, spending by SAC, was worked out. The algorithm of calculation is made on the basis of search of combinations of temperature and relative humidity of air from minimum to the maximum values, in which process the zone including this combination is defined. For the decision of the put tasks the climatic base, intended for the analysis of operating modes and calculations of power consumption by SAC, working in various time of days, was created. Program realization on the computer allows to carry out multiple calculations of power consumption by direct-flow SAC for premises of different function: a premise of a dining room, billiard, sports hall and office premise.
