Calculation Parameters for Cooling Period in Ukraine

Abstract. To ensure the completeness of the original data when designing ventilation systems, air conditioning systems and surface cooling in buildings with minor (up to 10 w/m2) heat gains, air moisture content was determined in July for regional cities of Ukraine based on analytical processing the existing regulatory data of climatic parameters. Moisture values, characteristic temperatures start and finish dates for cooling period in conjunction with other climate parameters, according to DSTU-N B V.1.1-27:2010, can be used to design and assess monthly, seasonal and annual heat consumption for microclimate providing systems in rooms, simplify the calculation methods of energy consumption for cooling and air-conditioning systems according to DSTU B A.2.2-12:2015. The proposed dates for the beginning and the end of cooling period, like dates of heating period, will ensure on time preparation of engineering systems of buildings to their seasonal operation etc. Based on the proposed temperature-time characteristics of cooling period, there is a corresponding rating of Ukrainian regional cities, which can describe the amount of expenses on the cooling system of the premises and buildings. Obtained table data is recommended for wide use in practice of design and maintenance of microclimate providing systems.

Key words: external air parameters, cooling period, representative date, average temperature, average moisture content
