METHOD OF MAINTENANCE OF RATED FLOW RATES OF WATER BY USERS OF CLOSED TWO-PIPE CENTRALIZED HEAT SUPPLY SYSTEM AT CHANGE OF FLOW RATES OF WATER Russian patent published in 1997 - IPC

FIELD: centralized heat supply systems. SUBSTANCE: pressure differential between inner chambers of delivery and suction manifolds of heat supply source is maintained. Pressure differential is maintained at points where all users are connected to. In case of change in flow rate of water through consumers, part of flow is bypassed from supply pipe line to return pipe line. Rate of bypass is increased or reduced proportionally to increased or reduced rate through consumer. EFFECT: enhanced efficiency. 1 dwg
