The specific embodiment
Enumerate following preferred embodiment and conjunction with figs. below, structure of the present invention and effect are elaborated.
As Fig. 2, shown in Figure 3, for using the storage-type heating system 10 of a preferred embodiment of the present invention, in configuration aspects, storage-type heating system 10 includes the water heater 30 that a water butt 20 and is fixedly arranged on water butt 20 1 sides, wherein water butt 20 has a water space that is used for the splendid attire water storage, one is positioned at water butt 20 bottoms and is communicated with the cold water inlet 22 of water space, one is positioned at water butt 20 tops and is communicated with the hot water outlet 24 of water space, one circulating water outlet 26 and that is positioned at water butt 20 bottoms and is communicated with water space is positioned at water butt 20 bottoms and is communicated with the recirculated water inlet 28 of water space, in addition, water butt 20 also has a temperature and pressure relief valve 29 and a temperature sensor 80a (as shown in Figure 1), temperature and pressure relief valve 29 is used to prevent that the water storage hydraulic pressure in the water butt 20 is too high and cause the damage of water butt 20, and temperature sensor 80a is used to then prevent that the too high water butt 20 that causes of water butt 20 temperature inside from damaging.Water heater 30 is connected with a gas inlet pipe 32, and gas can enter in the water heater 30 by gas inlet pipe 32, hot water supply device 30 burnings.
Storage-type heating system 10 also includes a heat pump 40, one first circulating water line 50, one second circulating water line 60, a controller 70 and a temperature sensor 80b.Heat pump 40 is fixedly arranged on water butt 20, and is connected with recirculated water inlet 28.First circulating water line, 50 1 ends connect water heater 30, and the other end connects an end communication loop water out 26 of heat pump 40, the second circulating water lines 60, and the other end connects water heater 30.Controller 70 electrically connects with water heater 30 and heat pump 40 respectively; Temperature sensor 80b is fixedly arranged on water butt 20, and electrically connects with controller 70, is used to monitor the water storage water temperature in the water butt 20.In addition, storage-type heating system 10 also includes a temperature switch 90, temperature switch 90 electrically connects with temperature sensor 80b with controller 70 respectively, supply the user to set the upper limit and the lower limit of water storage water temperature, 90 energy range of set temperature of temperature switch are between 30 degree are spent to 100, in the present embodiment, the ceiling temperature of setting the water storage water temperature is 60 ℃, lower limit temperature is 45 ℃, but the design temperature scope can be adjusted the bound temperature of water storage water temperature according to actual state not as limit.
Again as shown in Figure 1, temperature control method of water of the present invention includes the following step:
Step 1: make extraneous cold water W1 flow through cold water inlet 22 to the water space of water butt 20, form water storage W2, the water temperature of water storage W2 has a rough initial temperature that equals room temperature, in the present embodiment, it is 25 ℃, utilize heat pump 40 to extract water storage W2, water storage W2 recirculated water inlet 28 and first circulating water line 50 of flowing through is heated to water heater 30, water storage W2 after will heating again is back to via second circulating water line 60 and circulating water outlet 26 in the water space of water butt 20 and stores, sense after water storage W2 water temperature in the water butt 20 arrives 60 ℃ up to temperature sensor 80b, driving governor 70 control heat pumps 40 stop to extract.
Step 2: when many people use water storage W2 in the water butt 20 simultaneously, make water storage W2 flow to the washroom that it connects via hot water outlet 24 in large quantities, extraneous cold water W1 can flow to water butt 20 via cold water inlet 22, with amount of makeup water constantly, when the water yield of cold water W1 more and more, when making water storage W2 water temperature in the water butt 20 be lower than 45 ℃ of lower limits (lower limit temperature is not as limit), temperature sensor 80b can start heat pump 40 by controller 70, heat pump 40 will begin to extract the water storage W2 in the water butt 20, water storage W2 is reheated to lower limit more than 45 ℃ via recirculated water inlet 28 and first circulating water line 50 to water heater 30, be back in the water butt 20 with circulating water outlet 28 via second circulating water line 60 again, use to the user so that hot water to be provided constantly.
Learn via said method, the present invention is the high temperature that utilizes in the water butt 20, make the firing rate of water storage water temperature accelerate 2～3 times, reach energy-conservation effect in order to the ability that promotes water butt 20, and, traditional water heater can't reach high water yield, also sometimes hot and sometimes cold problem can take place, the ability that makes conventional water heaters make hot water can only be used for shower or small bath-tub and bath, when sharing as need 3～5 people, its ability is not applied and is used, but when the capacity of water butt 20 of the present invention is 170 liters, its hot water ability of making more than 50 degree is 3～4 times of conventional water heaters, general about 550 liters water yield (these data can change because of going into coolant-temperature gage) converts, no matter what (1～5 people) will use for a long time or use continuously user's number, water butt 20 all can provide stable hot water temperature, can not cause the problem that water temperature is sometimes hot and sometimes cold or hot water is under-supply.
Thus, temperature control method of water of the present invention is to utilize temperature sensor 80b to monitor water storage water temperature in the water butt 20 at any time, make the water storage water temperature remain on a predetermined temperature range, when the water storage water temperature is lower than the lower limit temperature that the user sets, can water storage be extracted to water heater 30 by heat pump 40 and reheat and since this moment water storage water temperature do not descend too much, therefore, water storage can be heated in the temperature range that the user sets apace, is used for providing constantly hot water.And, when the water storage in the water butt 20 by when heating circulation constantly, can be as the heat flow field effect, make water storage after the heating toward rising, allow water butt 20 tops all keep the state of sustainable hot-water supply.In addition, in step 1, if change the stronger water heater 30 of heating efficiency, more can promote the efficient of heating water storage, make hydronic speed faster, and in step 2, the ability of the storage capacity of water butt 20 and heat pump 40 circulation extraction water storages more can increase the efficient of storage-type heating system 10 hot-water supplies.
