Description
Technical field
The invention belongs to building and heating facilities, particularly relate to a kind of high-temperature phase change heat accumulation energy storage heat-exchange system.
Background technique
The areas such as many surrounding cities in the winter north, rural area do not have central heating, and a large amount of use disperses coal-fired arcola etc.
Mode is warmed oneself, and pollutant discharge amount is very big.In addition to needing more efficient heating system, coal substitution is to control for winter cleaning heating
Manage the main aspect of haze, including " coal changes electricity ", " coal changes gas ", distribution type renewable energy etc..Promote northern area winter clear
Clean heating, relationship north broad masses are warm to pass the winter and haze is administered, according to based on government driving, enterprise, resident can bear
Principle, suitable gas then gas, preferably electricity is then electric, utilizes clean energy resource as far as possible, accelerates to improve cleaning heating specific gravity.
Other clean energy resourcies such as wind-powered electricity generation, solar energy actually enter warming (such as solar energy power-up auxiliary, earth source heat pump
Heating system), it should be the medium-term and long-term selection slowly developed relatively.It is short-term it is more feasible, can be that " coal changes with extensive development
Gas " and " coal changes electricity ".The constraint of " coal changes gas " by the endowment of resources and energy security (external dependence degree) of China's " few gas ",
Main development bottleneck is the supply problem of natural gas.The cost of " coal changes electricity " is also more much higher than the heating of direct coal, but electric power
In addition to coal generates electricity, it can also be generated electricity using clean energy resource, Chinese Energy Safety be had no substantial effect on, so " coal changes electricity " is short
Phase is effectively and the heating mode that can promote on a large scale.
The clean energy resourcies such as electric power are widely used in order to mitigate winter city environmental pollution as caused by fire coal to adopt in various regions
It is warm.Implement " coal changes electricity " heating technology, replaces coal-burning boiler central heating, especially popularization power grid peak valley electric heating using electric power
Mode is an important channel of effective control Heating Period air quality.Electric heating implementation initial stage progress is slower, studies carefully its original
Because being that operating cost is excessively high, user is difficult to receive.And regenerative electrochemical heat supply heating uses phase-change material to utilize as accumulation of heat working medium
Low price valley power heats energy storage, electric heating is no longer consumed daytime, has apparent advantage in terms of power grid peak load shifting, can
Greatly to reduce user heating expense, the effective preferential policy for promoting time-of-use tariffs, to achieve energy-saving and emission reduction purposes.
