Technical field
The invention belongs to Heat Supply Engineering technical fields, and in particular to superposing type energy storage heat heat pump heating system.
Background technology
City size rapid development at present, while heating area expands year by year.Country is empty caused by heat supply to reduce
Gas is polluted in the implementation for actively pushing forward " coal changes electricity " policy.Heat pump techniques reduce primary energy as the representative of clean energy resource in heat supply
Source has leading position for the heat-supplying mode of thermogenetic environmental pollution.In current town region heat pump heat distribution system design
" paddy electricity accumulation of energy clean energy resource " is utilized to run electric energy storage system for thermal regenerator in the power supply valley period.For level peak, peak etc.
Period heat release, which advantageously reduces operating cost and distribution capacity, has a positive effect, and energy-storage heat pump system is current main heat supply
Pattern.
In the air source heat pump system of current accumulating type, system design usually independently sets storage pump with releasing to pump
It sets, storage pump connects heat resource equipment and energy storage tank, and connection energy storage tank and user terminal can be pumped by releasing.The storing energy and supplying hot system of conventional system
In be generally divided into the operational modes such as paddy valence electricity, peak valence electricity, par electricity：
(1) heat supply is in " the paddy valence electricity " period, and system enters accumulation of heat pattern, opens heat resource equipment and energy storage tank communicating valve is same
When close heat resource equipment and user terminal communicating valve, pass through storage pump carry out heat resource equipment, energy storage tank hot water circuit, complete one
A accumulation of energy process
(2) heat supply is in " par electricity " period, and system enters direct heating pattern, opens heat resource equipment and is connected to user terminal
Valve simultaneously closes off the communicating valve of heat resource equipment and energy storage tank, by release can pump carry out heat resource equipment, user terminal carry out hot water follow
Ring completes a direct heating process.
(3) heat supply is in " the peak valence electricity " period, and system enters Heat release mode, opens energy storage tank and user terminal communicating valve, together
When close heat resource equipment and energy storage tank communicating valve, by release can pump carry out heat resource equipment, energy storage tank progress hot water circuit, completion
One heat release heat supplying process.
