Abstract
The experience of application of self-conditioning systems in modern multistory buildings is described. The layout of provision of unit blocks of central air conditioners with self- contained sources of refrigeration is presented. Characteristics of compressor units added to standard central air conditioners are given. The calculation of operating conditions of the air conditioner in the warm time period in Moscow is presented.
