Analysis of annual power consumption by central air conditioning systems using the climatic data stochastic statistics model

Abstract

The purpose of the offered research is creation of a method to estimate annual power consumption by central air conditioning systems (ACS), using modern computer possibilities. The developed method is aimed at determining thermal, electric power and water consumption during a year by ACS taking into account their operation in different hours of the day and optimization of the inflow air treatment pattern on the basis of power input minimization. The MGSU Heating and Ventilation Chair has worked out a universal program for computer calculation of ACS power and water consumption. The analysis algorithm is made on the basis of search of the air temperature and relative humidity combinations from minimum to maximum values, which lead to determination of a zone having these combinations. To solve the above tasks provision has been made of a climatic data base to analyze operating modes and calculation of power consumption by ACS operating in various periods during 24 hours. The program computer performance enables multiple variant calculations of power consumption by direct-flow ACS for different purpose premises: a dining room, billiards, sports hall and office.
