Load Adaptive Combined Heating System and Heating Method

Abstract

The invention discloses a load adaptive combined heating system, which comprises a controller, a main heating device and a plurality of auxiliary heating devices, and further comprises a temperature sensor arranged in a main pipeline; a heat energy output pipe of the main heating device serves as the main pipeline, and heat energy output pipes of all the auxiliary heating devices serve as sub pipelines to be connected to the main pipeline; the temperature sensor and the controller are in communication connection; the controller is in double-direction communication connection with the main heating device and all the auxiliary heating devices; and a load adaptive heating control program is further configured in the controller and used for coordinately configuring all the auxiliary heating devices according to temperature data collected by the temperature sensor and operating parameters of the auxiliary heating devices. The invention further provides a heating method adopting the load adaptive combined heating system. Coordinate heating can be conducted according to the load change, the economical efficiency is improved, and the loss difference between all heat source devices can be reduced.

Description

technical field [0001] The invention belongs to the field of energy technology, and in particular relates to a heating system and a heating method. Background technique [0002] At present, the existing multi-heat source joint control methods in China are all designed for large-scale central heating systems. The system structure is huge and the pipeline is complicated, which is not suitable for small or building-level heating systems. Small-scale or building-level heating systems generally use boilers as heat sources. Different boilers supply heat to different areas. Cascade control cannot be formed between boilers, and heat sources cannot be coordinated and distributed. Excess heat and insufficient heat supply in areas with large heat load restrict the improvement of energy utilization. Contents of the invention [0003] Aiming at the deficiencies of the above-mentioned prior art, the present invention provides a load-adaptive combined heating system, which solves the te...
