Energy-saving control method and system for heat exchange station

Abstract

The present invention provides an energy-saving control method and system for a heat exchange station, including the following steps: respectively calculating the operating cost X of the heat exchange station 1 , economic benefit X, operational flow data; wherein, through the operating cost X 1 , the economic benefit X and the operating flow of the heat exchange station to control the operating parameters of the circulating pump unit. Using the above energy-saving control method and system, according to the thermodynamic parameters of the primary pipe network of the heating and heating system and the heating demand of the secondary pipe network, and considering the factors of peak and valley electricity prices, the heat exchange between the primary pipe network and the secondary pipe network is controlled by controlling the heat exchange. The flow rate of heat exchange at the station and the operating parameters of the circulating pump unit are used to achieve the best energy-saving effect of saving heat and electricity.

Description

technical field [0001] The invention relates to the technical field of heating engineering, and more particularly, to a heat exchange station energy saving control method and a heat exchange station energy saving control system for executing the heat exchange station energy saving control method. Background technique [0002] The heat exchange station is the key unit for heat exchange and liquid pressurization in the heating or heating pipe network system. Its operation quality not only determines the heating quality of the user end, but also relates to the energy saving and emission reduction of the whole society and the cost saving of heating enterprises. Synergistic. [0003] At present, in most heating systems, traditional methods are often used to estimate the heat exchange volume of the heat exchange station, and measures such as throttle valves are used to control the operating conditions of the circulating pump unit of the heat exchange station, which will inevitably...

Problems solved by technology

[0005] Therefore, the energy saving and emission reduction of the heat exchange station involves two levels: one is whether the heat exchanged between the primary pipe network and the secondary pipe network is reasonable, that is, insufficient heat exchange will lead to failure to meet the needs of heating users, while the heat exchange If it is too large, it will cause waste of heat; the second is how to save energy under the premise of ensuring the needs of heating users, especially how to make the circulating pump unit operate in the highest efficiency area, which can not only ensure energy saving effect but also keep the pump unit in a good operating state, prolong equipment lifespan

[0006] However, in the existing technologies related to energy saving of heat exchange stations, few people fully consider the optimization and control of these two levels of energy conservation. The heat demand is the largest at night, and the different electricity prices in peak and valley also have a major impact on the operating efficiency of the heat exchange station
