Accumulation of heat heat release principle explanation of the present invention：During Heating Season：1. low-temperature receiver 14, cold-storage cold water draw-off pump P3, cold-storage hot water is taken out
Take pump P4 to be stopped, the 4th electric control valve D, the 5th electric control valve E are closed.2. during accumulation of heat：Heat accumulation hot water draw-off pump P2
It is stopped, high-temperature water (heat supply network water supply) is by the second stop valve V2, the 3rd electric control valve C and by the second electric control valve B
Water at low temperature (heat supply network backwater) mixing for coming, control Shui Wen≤98 DEG C after mixing, are entered in tank by the top of energy storage tank 13 and (work as water supply
When temperature is less than 98 DEG C, water supply can be directly entered in tank), meanwhile, tank inner bottom part water at low temperature is by by accumulation of heat cold water draw-off pump P1
Heat supply network backwater is squeezed into, accumulation of heat is completed.3. during heat release：3rd electric control valve C is closed, and high-temperature water is flowed out by tank body top, is passed through
Heat accumulation hot water draw-off pump P2, the first stop valve V1 or the second stop valve V2 (control of valve 1 and valve 2, be described below) squeeze into confession
Hot systems, water at low temperature (heat supply network backwater) enters tank base by the first electric control valve A, completes heat release.4. connected mode is true
It is fixed：In heat supply first latter stage, when the water temperature of energy storage tank 13 (98 DEG C) disclosure satisfy that user's use requirement, the first stop valve V1 is closed, the
Two stop valve V2 are opened, using being directly connected to form；When outdoor temperature is further reduced, and reaches a certain value, the water of energy storage tank 13
Warm (98 DEG C) can not meet user's use requirement, now need to open the first stop valve V1, close the second stop valve V2, accumulation of energy hydro-thermal
Water after the heating temperature raising of thermal source 1 by supplying user.
Cold-storage of the present invention lets cool and is illustrated with case：During non-heating season：1. the pump of accumulation of heat side, electric control valve etc. are closed.2.
During cold-storage：Cold-storage cold water draw-off pump P3, the 5th electric control valve E are closed.Water at low temperature (cold net water supply) passes through the 4th motorized adjustment
Valve D enters tank base, and high-temperature water (tank body top) squeezes into cold net water return pipeline 15, completes to store by cold-storage hot water extraction pump P4
It is cold.3. when letting cool：Cold-storage hot water extraction pump P4, the 4th electric control valve D are closed.Water at low temperature (tank base) passes through cold-storage cold water
Draw-off pump P3 squeezes into cold net supply channel 17, and high-temperature water (cold net backwater) enters tank body top by the 5th electric control valve E, complete
Into letting cool.
It is hereby stated that, it is described above to contribute to skilled artisan understands that the invention, but not limit the present invention
The protection domain of creation.It is any equivalent described above, modification are improved without departing from the invention substance
