“…The design parameters of the outdoor air are important for determining the maximum capacity of air conditioning systems, as well as the volume in the building that will be occupied by the utilities and air ducts of these systems [1][2][3][4][5][6]. In addition, the design parameters significantly affect the economic characteristics of the building, both during its construction and operation [7][8][9][10][11][12].…”

The temperature and the enthalpy of the outdoor air are the main parameters of the outdoor environment, the design values of which must be assigned with a sufficient accuracy. Therefore, normalization of the design enthalpy using maps is unacceptable. The design outdoor air parameters for the warm period of the year for air conditioning in different countries are determined from the average multiyear data. However, most countries have adopted much shorter periods of exceeding the actual values of the outdoor air temperature and enthalpy than in Russia. In addition, the coasts of the most developed countries are washed by the waters of the seas and the oceans, which stabilize the weather in these countries, as a result of which the spread of parameter values from year to year in these countries is much less than in Russia having a continental climate. It is proposed to take into account the long-term excess of the calculated parameters in individual years when choosing the design temperature and enthalpy of the outdoor air for the warm period in Russia. The estimated increase in the calculated enthalpy by 4-5 kJ / kg showed that a significant increase in the size of air conditioning units will not be required.
