Detailed description of the invention
Embodiment 1, fluid heat transfer accumulation of heat control system
Fluid heat transfer system shown in Fig. 1, is filled thermal regenerator device 8 and three heat release thermophores 10 groups by threeBecome, and a fluid pool 13 form, three that fill thermal regenerator device 8 with fill hot channel 7 and be attached, andFluid is unloaded to fluid accumulation of heat pond by filling hot channel 7 or is directly filled into the thermophore of heat release pipelineIn, being attached with heat release pipeline 9 of three heat release thermophores 10, three heat release thermophores 19 and heat releasePipeline 9 is attached, and fills hot channel 7 simultaneously and is attached with heat release pipeline 9.
Described thermophore 8,10 is as in figure 2 it is shown, contained import 1 and 3 groups of the container exporting 2 by oneBecome, be provided with fluid 4 therein；
Fill thermal regenerator device 8 and fill after hot channel is connected, open and fill thermal regenerator device 8 and import and export 1 valve 11, willFluid is filled on hot channel 7, fluid by under going to drive at circulating pump by fluid transport to fluid poolOr be directly transported on heat release pipeline 9, fluid 4 directly carries heat release thermophore quilt by heat release pipelineUsing, after heat release thermophore is used, its fluid is again transported to heating region and heats, heatedFluid be placed in thermophore, be transported to fill hot channel region, fluid download to fill hot channel, realThe transmission of heat energy and large-scale thermal energy exchange and use are showed.
Being it desired to obtain three is all the regenerator temperature that temperature is the same, can fill thermal regenerator device and three by threeIndividual heat release thermophore is opened simultaneously and is carried out fluid circulation.
If fill thermal regenerator device by three to open simultaneously, start to open at a heat release thermophore, first is putAfter heat energy piled by thermal regenerator device, then carrying out heat release, then the 3rd to second, such order makes threeThe temperature of the individual thermophore being issued by difference, first the highest, second secondly, the 3rd is minimum, soSufficiently the heat energy of thermophore can be discharged.
Respectively or carrying object can also be jointly descended, it is also possible to download respectively, for putting by filling thermal regenerator deviceThermal regenerator device, the loading that the loading that can distinguish can also be distinguished, fills thermal regenerator device or heat release thermophore is permissibleUnlimited increase as required, until meeting needs.
In system carries out charge and discharge thermal process, central control system, by computer, software, sensor, electricitySub-valve, electrical switch etc. form, to arrange in each seam and each fluid tank sensor,Electronic valve, electrical switch, for realizing the control to whole system, it is achieved the charge and discharge heat of intelligence.
