Description

Technical Field

[0001] This utility model relates to the technical field of equipment related to structural design, specifically to a heating and cooling circulation device. Background Technology

[0002] Waste heat recovery refers to the process of capturing and reusing heat generated during industrial production, power generation, or other energy consumption. This heat is usually lost to the environment as waste heat, but through waste heat recovery technology, it can be used to heat water, heat buildings, drive absorption chillers, etc. This technology helps reduce energy consumption, save costs, and reduce negative environmental impacts.

[0003] In traditional adsorption column cooling systems, the heat from the adsorption column is typically recovered to the chiller via low-temperature heat transfer oil, and then the chiller releases the heat from the heat transfer oil into the atmosphere to maintain the low-temperature environment of the adsorption column. However, the current adsorption column is designed to adsorb at a low temperature, and heating is a regeneration process. After regeneration, the residual heat from cooling down is transferred to the next set of adsorption columns that need to be heated and regenerated via heat transfer oil. This not only reuses the heat but also significantly reduces the energy consumption of the chiller.

[0004] Based on the aforementioned existing problems, after thorough comparison and demonstration, corresponding technical modifications were proposed, and a heating and cooling circulation device was developed and designed. Utility Model Content

[0010] Temperature sensors T1, T2, and T3 are installed in the first adsorption column A, the second adsorption column B, and the third adsorption column C;
