Abstract

The invention belongs to the technical field of heating, ventilating and air-conditioning, and in particular relates to a medium and low temperature thermal energy heating system based on heating-up absorption-compression heat exchange, which includes sequentially connected: medium and low temperature heat source, heat source station, primary network, heat power station and secondary Secondary network; the heat source station is the first water-to-water heat exchanger, and the heat station is a compression heat exchange unit or the second water-to-water heat exchanger; the medium and low temperature heat source is medium and low temperature industrial waste heat, or medium and deep geothermal heat , or medium and low temperature circulating water from solar collectors. According to the characteristics of the medium and low temperature heat energy carrier, the present invention rationally configures the heat exchanger in the medium and low temperature heat source station, and rationally configures the compression heat exchange unit in the heat power station according to the characteristics of the heat user, which can greatly reduce the return water temperature of the primary heating network and increase the primary water supply temperature , greatly increase the economical heat transfer distance of industrial waste heat; it helps to efficiently use medium and low temperature heat energy to provide heating source support for surrounding towns, and reduce the consumption of fossil energy and the emission of pollutants in the heating system.

Description

technical field [0001] The invention belongs to the technical field of heating, ventilating and air conditioning, and in particular relates to a medium and low temperature thermal energy heating system based on a temperature-rising absorption-compression heat exchange. Background technique [0002] Low-temperature industrial waste heat, deep geothermal heat and solar energy can be used as heating sources, which can greatly reduce the fossil energy consumption of central heating in northern cities and towns, and significantly reduce the emission of air pollutants. Currently. Due to the spatial inconsistency of heat source distribution and heat load distribution, especially the heat source and heat users with large spatial distribution distances, the medium and low temperature heat energy results in a relatively small temperature difference in heat energy transmission, resulting in high cost of long-distance transmission, and it is difficult to be centrally supplied by cities ...
