Analysis of annual energy consumption of air conditioning systems, calculated on the basis of probabilistic-statistical climate model

[摘要] The calculations of energy consumption of heat, water and electricity by air conditioning systems, which provide the outdoor air processing according to different schemes, can be made only on the basis of data on the frequency of combinations of the outdoor air temperature and its relative humidity. The probabilistic-statistical climate model has been chosen as the basis for the calculation results. On the basis of climatic models for Moscow, the outdoor air treatment in the air conditioning units, which operate according to the schemes of the direct flow with the first and second heating, as well as the adiabatic process in the humidifier unit in the cold period of the year and cooling in the surface air cooler in the warm period of the year with the subsequent second heating; with the first heating and the adiabatic process in the humidifier unit, equipped with an air bypass in the cold period of the year, as well as the controlled cooling process in the surface air cooler in the warm period of the year. As a result of the calculations it was found that all the components of energy costs are quite significant and cannot be neglected when comparing the options.
