Multi-heat source annular pipe network power transmission system, system configuration method and operation mode

Abstract

The invention discloses a power transmission system of a multi-heat source loop pipe network, a system configuration method and an operation mode. One or more sets of fixed speed circulation pumps which are same in rated flow and different in rated lift are respectively arranged at various types of heat sources. When more sets of fixed speed circulation pumps are arranged, a plurality of sets of circulation water pumps which are same in rated flow and different in rated lift are installed in parallel; corresponding sets of circulation water pumps are operated under various types of working conditions; the set number corresponds with the number of operation working conditions of the heat sources; and a flow control valve capable of quantitatively controlling flow is arranged at each user place. By means of the heat sources operating under various types of operation working conditions, the circulation water pumps corresponding to the operation working conditions are started respectively; the conveying capacity of the pipe network and the operation effect of the pipe network under various types of normal operation working conditions are ensured; and the electric energy consumption ofthe power transmission system is reduced.

Description

technical field [0001] The invention relates to a central heating system, especially a multi-heat source annular pipe network central heating system. Background technique [0002] In the central heating system, the power delivery system provides the delivery power for the circulating heat medium. The power transmission system mainly includes circulating water pumps, water pump inlet and outlet pipes, valves, accessories, and water pump control devices. Whether the configuration of the power transmission system is reasonable or not has an important impact on the operation economy, safety and reliability of the heating system. [0003] The pipe network structure and operation mode of the multi-heat source ring pipe network heating system have the following characteristics: (1) The main pipe network is composed of one or more ring pipe networks. (2) There are multiple heat sources, and each heat source is equipped with a corresponding power delivery system. (3) The power del...
