INCREASING THE HYDRAULIC STABILITY AND ENERGY EFFICIENCY OF HEATING NETWORKS IN URBANIZED AREAS (CASE STUDY OF BISHKEK)
Keywords:
heat supply, water-jet elevator, individual heat substation (IHS), PID control, energy efficiency, 4GDHAbstract
The article examines the operational problems of district heating systems (DHS) under conditions of complex terrain and thermal power shortages. The inefficiency of using traditional water-jet elevators in modern hydraulic regimes is justified. A transition to independent individual heat substations (IHS) with weather-compensated PID control is proposed, which allows for reducing unproductive heat energy losses by 15–18% and improving the hydraulic regime of heating networks.
