Abstract

Housing and communal services in Kyiv have more than 10,000 multi-storey houses, and in Ky-iv region, there are more than 5,000. Reducing energy consumption for housing, heat and water supply, and lighting services should be considered as reducing energy costs. The trouble-free operation of the equipment is of the utmost importance. Its resource on many utilities has a minimum margin of safety. Centralized analysis of the equipment control, accounting of motor resources and, accordingly, timely preventive work allow extending the service life of many components of engineering systems in the utility sector, transport, and industry. These problems are solved by distributed systems of automated control of engineering equipment, including control systems of the hot water supply scheme for modern new buildings. In modern new buildings, there is used a scheme of hot water supply (HWS) with two circulating pumps and the HWS regulator. The control cabinet, developed in the IMMSP of the NAS of Ukraine, is made on the basis of the MRTP-7 controller with the corresponding software consisting of gen-eral and special purpose programs. The article considers the principles of building a control sys-tem for hot water supply, considers the software functions of the system, presents a mathemati-cal model of the HWS system, describes a laboratory test site for testing algorithms for HWP control and modeling the HWS control process. The scientific and technical solutions provided in the article can be used in the development of automated control systems for engineering equipment in the utility sector.
