Automated individual heat point with secondary heat energy recovery system

Abstract

Objective. An urgent problem of modernizing engineering systems of buildings to ensure energy efficiency and consumer comfort. It is proposed to introduce a waste heat energy recovery system. The result will be a reduction in climate impact and benefits for consumers.Method. A method of heating water for a hot water supply system by partial heat energy recovery using high-potential energy of a gaseous refrigerant superheated after compression by a compressor of a refrigerating machine with a temperature of up to 100°C. is proposed. Automation of an individual heating point is carried out by a controller programmed with the logical Aries SPK 107[M01]; control of water heating in the circuits is carried out according to the proportional-integral-differential law by influencing the control valves and controlling the operation of circulation pumps.Result. An automation and dispatch system has been developed for a double-circuit individual heating point with weather-dependent regulation of the heating system. A diagram of the design of the recovery system and the organization of technical automation equipment is outlined.Conclusion. An automation scheme for an individual heating point has been proposed, ensuring autonomous operation of a source of secondary thermal energy.
