Abstract

Issues of microclimate mitigation in Uzbekistan during the summer period require urgent resolution. It should be noted that currently, there is very little research and practical recommendations related to the formation of a favorable microclimatic environment in cities with a hot climate. The simplest and most economical way of cooling in dry and hot climates is the evaporative cooling of a dry air stream. One of the possible ways to increase the system's efficiency is the use of night evaporative cooling of water, followed by its accumulation for daytime cooling in heat-insulated batteries. The conducted experiments testify that rather simple and cheap natural sources of cold can be used along with cold machine sources for air conditioning residential buildings in Uzbekistan.
