Description
Technical field
The utility model belongs to hot water facility technical field, is specifically related to a kind of heat storage water tank for solar water heating system.
Background technology
In current solar water heating system, the hot water that user needs output temperature stable usually.In the prior art, normally utilize, on output pipe, mechanical type or electronic heat control valve are installed, achieve the goal.But it is higher that this mode exists cost, and fault rate is higher, and in different flow situation, output temperature is the shortcomings such as non-directional systematic error.Be badly in need of the temperature adjustment technology of a kind of stable output, life-span permanent, reliable operation to promote the quality of water supply of solar water heating system, the present invention proposes to overcome the above problems.
Utility model content
The purpose of this utility model is to provide a kind of heat storage water tank for solar water heating system, solves the technical problem of the hot water temperature's instability exported in existing solar water heating system.
The technical solution of the utility model is achieved in that a kind of heat storage water tank for solar water heating system, comprising: heat storage water tank outer wall, heat storage water tank inwall, be provided with heat-insulation layer between heat storage water tank outer wall and heat storage water tank inwall; Hot water inlet, is arranged on 10cm place bottom heat storage water tank; Cooling water inlet, is arranged on 60cm place above hot water inlet; Thermometric blind pipe, is arranged between hot water inlet and cooling water inlet; Temperature sensor, is arranged in thermometric blind pipe; Level measuring pipe, is arranged in heat storage water tank; Level sensor is arranged in level measuring pipe; Controller, is electrically connected with temperature sensor and level sensor, and wherein, hot water inlet and cooling water inlet are in " L " type.
Preferably, described controller is microprocessor.
Preferably, described controller is Programmable Logic Controller.
The beneficial effects of the utility model are, cold water outlet and hot water mouth lay respectively at the upper and lower of temperature sensor, and the district that so just formation one is very large in heat accumulation, reaches the technique effect of the constant hot water of output temperature.
Accompanying drawing explanation
Fig. 1 is the structural representation of the heat storage water tank for solar water heating system of the present utility model;
Fig. 2 is the schematic diagram that the heat storage water tank for solar water heating system of the present utility model is arranged in solar water heating system.
In figure: 1. hot water inlet, 2. thermometric blind pipe, 3. cooling water inlet, 4. heat storage water tank outer wall, 5. heat storage water tank inwall, 6. overflow pipe, 7. tank entry, 8. tank lid, 9. water level signal line, 10. level measuring pipe, 11. level sensors, 12. heat-insulation layers, 13. water outlet of water tank, 14. sewage draining exits, 15. temperature sensors, 16. controllers, 17. moisturizing magnetic valves, 18. solar thermal collectors, 19. supplementary energies, 20. user sides, 21 water circulating pumps.
Detailed description of the invention
Below in conjunction with the accompanying drawing 1 in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of heat storage water tank for solar water heating system as shown in Figure 1, comprising:
Heat storage water tank outer wall 4, heat storage water tank inwall 5, be provided with heat-insulation layer 12 between heat storage water tank outer wall 4 and heat storage water tank inwall 5; Hot water inlet 1, is arranged on 10cm place bottom heat storage water tank; Cooling water inlet 3, is arranged on 60cm place above hot water inlet 1; Thermometric blind pipe 2, is arranged between hot water inlet 1 and cooling water inlet 3; Temperature sensor 15, is arranged in thermometric blind pipe 2; Level measuring pipe 10, is arranged in heat storage water tank; Level sensor 11, level sensor 11 is arranged in level measuring pipe 10; Controller, is electrically connected with temperature sensor and level sensor, and wherein, hot water inlet and cooling water inlet are in " L " type.
The operation principle of this heat storage water tank is, hot water density is utilized to be less than the characteristic of cold water density, creationary cooling water inlet is arranged on hot water inlet, hot water inlet and cooling water inlet, in " L " type, are oppositely arranged, the district that so just formation one is very large in water tank, district's volume is large, leaving water temperature fluctuation is little, and temperature adjustment is more accurate, and antijamming capability is strong.
Fig. 2 shows the structure chart this heat storage water tank being arranged on solar water heating system, and the solar water heating system course of work is as follows:
The temperature sensor be placed in thermometric blind pipe 2 detects water tank water temperature.And water temperature signal is transferred in controller 16, and compare with the temperature value that controller 16 is arranged, and start different ancillary equipment carry out temperature adjustment according to the water level signal that level sensor 11 gathers.When heat storage water tank water temperature is lower than design temperature, controller 16 controlled circulation water pump 21 from pump outlet absorb water and pass through supplementary energy 19(electricity or other conventional energy resources) heating after, get back to heat storage water tank by hot water inlet 1, when temperature arrives design temperature, stop heat cycles.When heat storage water tank water temperature is higher than set water temperature, controller 16 is opened moisturizing magnetic valve 17 and is mended cold water to heat storage water tank, time equal with design temperature, moisturizing stop, or level sensor 11 detect heat storage water tank arrive full-water level close moisturizing magnetic valve by controller 16.
In sum, the utility model has the advantage of and be arranged on hot water inlet by cooling water inlet, hot water inlet and cooling water inlet are in " L " type, be oppositely arranged, the district that so just formation one is very large in water tank, district's volume is large, leaving water temperature fluctuation is little, and its structure is simple.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
