The article analyzes the shortcomings of the climate information presentation form, which is currently used for the designing air conditioning systems.An analysis of these shortcomings is made. It is shown that the regulatory climate information provided in SNiP 23-01-99 (Construction climatology in the form of design parameters A and B for the warm and cold period of the year) is not suitable for these purposes. The requirements for the form of information presentation and its content are formulated. Analyzing the presentation of climate information is close to the proposed use of the form. This information is in the form of tables: temperature–relative humidity; temperature–enthalpy; temperature by dry and wet thermometers. It is shown that information in the form of the specified tables can be used to solve the tasks outlined in this article, which are solved at the initial design stage. The results of approbation for the considered form of climate information in solving practical problems are demonstrated. Among these results, special attention is paid to the dependence of the installation capacity of the subsystems on the time of lack of standardized parameters of the air environment in the room. The example also shows that information on the consumption of cold, heat, air, and water during heat and moisture treatment of air in air conditioning systems can be determined for different estimated periods of time: for the year as a whole, for the seasons of the year, by months, and also for shifts (eight hours) of periods specified. These results were obtained using a computer program that implements the recommended form of presenting information about climate for designing air conditioning systems.

Keywords: air conditioning system, climate information, subsystem installation performance, operating costs, t-d-table, elementary climate platforms, energy-saving modes, estimated time period, I-d-diagram of humid air.
