Problems solved by technology

[0008] In the prior art solutions, this part of the heat cannot be utilized
Of course, there are also some workarounds, such as reducing heat supply or interrupting heat supply for a period of time before a sudden change in demand, but there are also some problems in this approach: on the one hand, it is troublesome to set the operation, on the other hand, it will cause heat supply The quality has declined, and there will still be some heat loss

Embodiment 1

[0042] In the following, the technical solution of the present invention will be described in detail in conjunction with a public building heating system case. In this embodiment, the energy storage module 3 is a phase-change energy storage module. The characteristics of the requirements corresponding to this embodiment are:

[0043] Working hours (between 8:00 am and 18:00 pm) are normal loads;

[0044] The rest time (between 18:00 pm and 8:00 am the next day) is low-load operation, the main purpose is to prevent the pipes from freezing, and can be used to properly maintain the indoor temperature.

[0045] Such as figure 2 As shown, under normal load conditions during working hours, the heat source side system 1 is connected to the end system 2, and the heat source side system 1 provides heat for the end system 2. The supply and return water parameters of heat source side system 1 and terminal system 2 are both 60 / 50°C;

[0046] Such as image 3 As shown, at the intersec...

Abstract

A heat recovery and sustained release device used for a heat supply system includes a heat source side system (1) and an end system (2), and also includes an energy storage module (3) and an internalcirculation pump (4); and through adoption of an energy storage technology, when a load of the end system produces a sudden change from large to small, heat is quickly extracted and stored from the end system and is used for eliminating thermal inertia of the heat supply system.

Description

technical field [0001] The invention relates to a heat recovery and slow-release device and method for a heating system. Using energy storage technology, when the load of the end system changes suddenly from large to small, the heat is quickly extracted from the end system and stored, and stored. The utilized device and method belong to the technical field of heating systems. Background technique [0002] The thermal inertia of the heating system is an important factor restricting on-demand heating, especially for the most important intermittent heating demand in on-demand heating, the existing technical solutions are difficult to meet the requirements of energy-saving operation. specific: [0003] For public buildings, normal heating is usually required during working hours, and no heating at night or maintenance of anti-freezing operation is sufficient; [0004] For residential buildings, if the user goes to work during the day and there is no one at home, the heating ca...
