Embodiment
[0033] Please refer to the attached figure 1 As shown, the present invention is a time-sharing ratio heating system for urban heating with a fixed phase change heat storage module, including the direct heating electric boiler 1, a fixed phase change heat storage module 2, a frequency conversion water pump 3, and a frequency conversion water pump 3', plate heat exchanger 4, heat user 5, valve.
[0034] The direct-heating electric boiler 1 of the time-sharing ratio heating system of the fixed phase change heat storage module used for urban heating is connected to the plate heat exchanger 4 through pipelines.
[0035] The fixed phase change heat storage module for urban heating The fixed phase change heat storage module 2 of the time-sharing ratio heat supply system is connected to the plate heat exchanger 4 through pipelines.
[0036] The plate heat exchanger 4 of the time-sharing ratio heat supply system of the fixed phase change heat storage module used for urban heating is r...

The invention discloses a time-sharing matching heat supply system of a shaping phase change heat storage module for urban heat supply, and relates to the field of urban heat supply. The system comprises a directly-heated electric boiler, a shaping phase change heat storage module, a variable frequency water pump, a plate heat exchanger, a heat user and a valve. In the low-price electricity period at night, the shaping phase change heat storage module stores heat through electric energy, and meanwhile, the shaping phase change heat storage module and the directly-heated electric boiler supply heat together; and in other time periods in the daytime, only the shaping phase change heat storage module is used for heating. The time-sharing matching heat supply system of the shaped phase change heat storage module for urban heat supply is small in occupied space, effectively reduces operation cost, realizes zero emission of carbon dioxide at the same time, responds to the national claim of carbon reaching peak and carbon neutralization, and plays a positive role in peak clipping and valley filling of a power grid.
Description
technical field [0001] The invention relates to the field of urban heat supply, in particular to a time-sharing ratio heat supply system of a fixed phase change heat storage module for urban heating. [0002] technical background [0003] Carbon dioxide emissions are an important indicator for judging the quality of the ecological environment. Therefore, my country has put forward the important proposition of "carbon peaking and carbon neutrality", which is used to improve my country's ecological environment and strengthen the overall construction of ecological civilization. [0004] In 2020, the installed capacity of power generation in my country will continue to increase, of which the new installed capacity of renewable energy power generation and nuclear power will account for more than 70% of the total increase, indicating that my country's power supply will become more and more sufficient. At the same time, based on my country's special power system, with the reform of ...
