“…Much attention is paid to the calculation of energy costs for processing the supply air when designing buildings in different countries [1][2][3][4][5][6]. In the Russian Federation, the energy consumption by air conditioning systems is considered as a significant one, as well [7][8][9][10][11][12]. For Hanoi, where air conditioning systems operate in hot and humid climatic conditions of the Central part of North Vietnam, the assessment of energy consumption by these systems is not less important [13][14][15].…”

The repeatability of outdoor air temperature and enthalpy combinations in a construction area is a necessary initial information for calculating the energy consumption of air conditioning systems. The most convenient form of presenting climatic data in such calculations is the probabilistic-statistical model, which constitutes a Table, the cells of which show the probabilistic repeatability of the outdoor air temperature and relative humidity. The parameter values given on the vertical and horizontal scales, that form the cell boundaries, can be taken with larger or smaller increments. The paper that served as the basis for this article, provides verification of the initial climatic model detailing experimentally under full-scale conditions in the city of Hanoi (Vietnam). The criterion for the appropriate model detailing was the deviation of the energy consumption estimates of the room cooling system, got experimentally and by calculation. Moreover, the calculations were performed not only on two climate probabilistic and statistical models, but also on the data of direct measurements of the outdoor air temperature and relative humidity with an accuracy of 0.1 for temperature and up to 2 % for relative humidity.
