According to embodiments of the invention, above-mentioned three kinds of different heat supply modes can be arranged has different priority, different from heat condition to adapt to.Such as, the cycle subsystem under first mode can be set to high priority, and the cycle subsystem under the second pattern can be set to medium priority, and the cycle subsystem under the 3rd pattern can be set to low priority; Or the cycle subsystem under the second pattern can be set to high priority, the cycle subsystem under first mode can be set to medium priority, and the cycle subsystem under the 3rd pattern can be set to low priority.By the setting of priority, can intelligent setting be carried out according to the building heat energy utilization state of reality and regulate different heat supply modes, to realize the most reasonably heat energy utilization.
According to the flow chart of the heating system operation method of seasonal storage of the present invention as shown in Figure 3.
In step 301, carry out operational mode judgement.Area residing for the building of current required heat supply and running time decision-making system belong to which kind of operational mode.Particularly, such as, when this system cloud gray model is when the winter of Temperate Region in China building, be building Winter heat supply pattern by default; When this system cloud gray model is when the summer of Temperate Region in China building, be building accumulation of heat in summer pattern by default; When this system cloud gray model in torrid areas building spring/autumn time, be building accumulation of heat/heat supply mode by default.
Then enter step 302, carry out the timetable setting of operation season according to selected system running pattern.If current season is non-heating season, be then set to non-heating season timetable; If current season is heating season, be then set to heating season timetable.Such as, when Temperate Region in China summer, can set 10:00-15:00 is thermal storage time, and 18:00-23:00 is heating time.When Temperate Region in China winter, can set 17:00-second day 9:00 is heating time.
Operational mode enters step 303 after judging and carries out pattern switching.The current time that acquisition system is run, selects corresponding pattern according to selected operation season timetable.If under current system operates in accumulation of heat pattern (such as the noon of non-heating season), enter step 304 and start accumulation of heat pattern, under if current system operates in heat supply mode (such as, the night of heating season) then enter step 312 and start heat supply mode.
Under accumulation of heat pattern, first enter step 305, judge that the heat-collecting temperature of solar thermal collector 101 is whether higher than the temperature of short-term layer-stepping hot water storage tank 103, and detect in step 306 pair cross-season heat-storage body 104 temperature simultaneously.If the heat-collecting temperature of solar thermal collector 101, higher than short-term layer-stepping hot water storage tank 103 temperature, enters step 307, start collecting system, by solar thermal collector 101, heat is delivered to short-term layer-stepping hot water storage tank 103 by the first plate type heat exchanger 102 by heat, then enters step 308.If the heat-collecting temperature of solar thermal collector 101, lower than short-term layer-stepping hot water storage tank 103 temperature, does not start collecting system and directly enters step 308.Carry out short-term layer-stepping hot water storage tank 103 load leaving water temperature in step 308 to detect, then step 309 is entered, judge short-term layer-stepping hot water storage tank 103 load leaving water temperature whether higher than the temperature of the cross-season heat-storage body 104 detected in step 306: if short-term layer-stepping hot water storage tank 103 load leaving water temperature is higher than the temperature of cross-season heat-storage body 104, enters step 311 and start accumulation of heat, namely after the thermal stratification process of short-term layer-stepping hot water storage tank 103 inside, the high-temperature water being positioned at short-term layer-stepping hot water storage tank 103 top is sent to cross-season heat-storage body 104 by water pump.After carrying out heat exchange cooling by the inner coil pipe of cross-season heat-storage body 104, cooled current get back to the bottom low temperature side of short-term layer-stepping hot water storage tank 103, then are provided by the first plate type heat exchanger 102 and get back to solar thermal collector 101 and heat.If short-term layer-stepping hot water storage tank 103 load leaving water temperature, lower than the temperature of cross-season heat-storage body 104, enters step 310 and stops accumulation of heat, and return step 309, regularly judgement is compared to the temperature level of short-term layer-stepping hot water storage tank 103 load leaving water temperature and cross-season heat-storage body 104.
Under the heat supply mode of step 312, first enter step 313, judge that the heat-collecting temperature of solar thermal collector 101 is whether higher than the temperature of short-term layer-stepping hot water storage tank 103.If the heat-collecting temperature of solar thermal collector 101, higher than short-term layer-stepping hot water storage tank 103 temperature, enters step 315, start collecting system: heat is delivered to short-term layer-stepping hot water storage tank 103 by plate type heat exchanger 102 by heat by solar thermal collector 101, then enters step 316.If the heat-collecting temperature of solar thermal collector 101, lower than short-term layer-stepping hot water storage tank 103 temperature, does not start collecting system and directly enters step 316.Carry out short-term layer-stepping hot water storage tank 103 load leaving water temperature in step 316 to detect, then enter step 317, judge that whether short-term layer-stepping hot water storage tank 103 load leaving water temperature is higher than the heat supply temperature set.In the present invention, heat supply temperature such as can be set to 50 DEG C.If short-term layer-stepping hot water storage tank 103 load leaving water temperature is higher than setting heat supply temperature, then enter step 318, start the first heat supply mode, the direct heat energy collected by solar thermal collector 101 carries out heat supply in the first mode.Particularly, heat, after the first plate type heat exchanger 102 heat exchange, is delivered to short-term layer-stepping hot water storage tank 103 by the hot water after being heated by solar thermal collector 101.The high-temperature water being positioned at short-term layer-stepping hot water storage tank 103 top is sent to the second plate type heat exchanger 105 by water pump.By the second plate type heat exchanger 105, heat is delivered to heat supply building 107, after carrying out heat exchange cooling, cooled current get back to the bottom low temperature side of short-term layer-stepping hot water storage tank 103 by the second plate type heat exchanger 105, complete the process of the heat supply to building.
If judge the heat supply temperature of short-term layer-stepping hot water storage tank 103 load leaving water temperature lower than setting in step 317, then enter step 314, cross-season heat-storage body 104 temperature is detected.Then enter step 319, judge that whether the temperature of cross-season heat-storage body 104 is higher than the heat supply temperature set, if higher than, enter step 320 and start the second heat supply mode.In this mode, heat supply is carried out by cross-season heat-storage body 104 pairs of buildings.Particularly, the cold water bottom short-term layer-stepping hot water storage tank 103, flows through and is heated after the cross-season heat-storage body 104 storing heat energy, then flow back into the top of short-term layer-stepping hot water storage tank 103, completes to the process of short-term layer-stepping hot water storage tank 103 heat supply.Then the hot water of short-term layer-stepping hot water storage tank 103 is heat supply building 107 heat supply through the heat exchange of the second plate type heat exchanger 201 again, and cooled current get back to the bottom low temperature side of short-term layer-stepping hot water storage tank 103 by the second plate type heat exchanger 105.
