Abstract

The article discusses the methodology for calculating the annual, seasonal and monthly consumption of heat, cold, electricity and water for air conditioning systems based on the temperatures and enthalpies of outdoor air averaged for each weather zone during the working day according to a probabilistic-statistical climate model. The article contains a brief description of the engineering methodology for quick manual calculation of resource consumption with a comparison of the results when using simplified tables of climatic information about weather zones of various external air purification in devices of the central air conditioning system. An example of calculating the annual costs for a system controlled by the "optimal modes" method according to the direct flow scheme with a bypass of the humidification chamber and the controlled process in the air cooler is studied. The advantages of the proposed engineering method lie not only in accuracy, but also in that it allows you to consider the operation of the installation during the year with greater detail for each air purifier. It is shown that the simplified procedure is suitable for use, since it gives discrepancies with machine calculation, which is no more than 10%, which is acceptable for engineering practice.
