Problems solved by technology

[0002] In the central heating system, due to the change of ambient temperature and the heat consumption behavior of a large number of heat users, there is always a huge difference between the peak and the trough of the heat source load, that is to say, a certain installed capacity of the heat source is always facing the load. Demand exceeds supply during peak hours, resulting in a decline in service quality or user experience, and oversupply in the face of low loads, resulting in energy waste or reduced operating efficiency
Therefore, the determination of the installed capacity of concentrated heat sources has always been a thorny issue

Embodiment Construction

[0019] Below with the accompanying drawings ( figure 1 ) to illustrate the present invention.

[0020] figure 1 It is a structural schematic diagram of a central heating and cooling combined system with an energy storage tank for implementing the present invention. Such as figure 1 As shown, the combined central heating and cooling system with an energy storage tank is characterized in that it includes an energy storage tank 13, and the energy storage tank 13 is connected to the heat source heat network heating system (including heat source 1 and heating network water supply pipeline 2, etc.), the energy storage tank is also connected to the cold source cold network cooling system (including cold source 14 and cold network water supply pipeline 17, etc.) through the second pump valve pipeline. The inner cavity of the energy storage tank 13 includes three space layers from bottom to top, namely, a cold medium layer, a transition medium layer and a heat medium layer. The inn...

Abstract

The invention discloses a centralized heating and cooling combined system with an energy storage tank. The centralized heating and cooling combined system can be used for stabilizing energy load, reducing installed capacity, lowering great regulation needed by reduction of load changes, improving economical efficiency and improving the reserve capacity of the centralized heating or cooling system by virtue of energy storage action of the large energy storage tank under low load, and energy release action of the large energy storage tank under high load. The centralized heating and cooling combined system with the energy storage tank is characterized by comprising an energy storage tank which is connected to a heat source heating network heat supply system through a first pump valve pipeline, wherein the energy storage tank is further connected to a cold source cooling network cold supply system through a second pump valve pipeline.

Description

technical field [0001] The invention relates to central heating and cooling technology, in particular to a combined central heating and cooling system with energy storage tanks, which can store energy at low loads and release energy at high loads through large energy storage tanks. It can be used to stabilize energy load, reduce installed capacity, reduce large adjustments required due to load changes, improve economy, and increase reserve capacity of central heating or cooling systems. Background technique [0002] In the central heating system, due to the change of ambient temperature and the heat consumption behavior of a large number of heat users, there is always a huge difference between the peak and the trough of the heat source load, that is to say, a certain installed capacity of the heat source is always facing the load. Demand exceeds supply during peak hours, leading to a decline in service quality or user experience, and oversupply in the face of low loads, resu...
