Evaluation of the Accuracy and Completeness of the Climate Model for Calculating the Power Consumption by Air Conditioning Units

The accuracy of estimating seasonal power consumption by air conditioning units in rooms depends on the accepted climate model as the initial climate information. The estimation of the accuracy of determining the power consumption by the air conditioning system in Moscow was carried out by calculation. Three variants of the probabilistic-statistical model were considered: two models obtained from data of different weather stations according to different weather stations: VDNKh (Exhibition of Achievements of National Economy) and Moscow State University for the time period 1966–1980, and the third according to MSU data for years 1980–2010. The results of calculating the power consumption of the air conditioning unit according to the data of various weather stations in the same locality, relating to the same period, practically coincide. The results of calculating the power consumption by the air conditioning unit, according to the data obtained at one weather station during different periods, reflect the weather features of each segment. Moreover, various details of the probabilistic-statistical climate model were considered, so the models consisted of cells of combinations for temperature and relative humidity with different steps: temperature from 2^оC to 1^оC, relative humidity from 5% to 2.5%. The probabilistic-statistical climate model is the most acceptable for calculating the inertia-free process of air treatment in air conditioning units.
