The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
The non-pressure-bearing solar water heater of a kind of split as shown in Figure 1 comprises: solar vacuum tube collector 1, horizontal storage tank 22, circulation line 15, inlet pipeline 17, outlet pipeline 16, water return pipeline 14 and temperature controller 3.Be provided with dividing plate 2.1 in the described horizontal storage tank 2 and described horizontal storage tank 2 is divided into cold water storage cistern 2.3 and about 2.2 two parts (referring to Fig. 2) of boiler.The temperature difference circulating pump 4 that described circulation line 15 is provided with.Described outlet pipeline 16 is provided with hot water booster pump 5.Be respectively equipped with water solenoid valve 6 and pipeline circulating electromagnetic valve 8 on described water inlet, the outlet pipeline 17,16.Reach on the water return pipeline 14 in the described solar vacuum tube collector 1 and be respectively equipped with heat collector sensor 10 and pipeline cycle sensor 11.Be respectively equipped with water-temperature water-level sensor 9 and water tank temperature sensor 12 in the cold water storage cistern 2.3 of described storage tank and the boiler 2.2.Described sensor and magnetic valve all link to each other with temperature controller 3 and by its control, therefore have the function of automatic loading water, circulation, heating.The position of described horizontal storage tank 2 is lower than described solar vacuum tube collector, and the difference in height between the thermal-arrest circulation is little, and pipeline is shorter, has guaranteed reliablely, and heat waste is little.In order to increase the convenience of use, be provided with the electrical auxiliary heater 7 that links to each other with temperature controller 3 in the boiler 2.2 of described storage tank.In order to increase reliability of products, described circulation line 15 is provided with antifreeze cycle sensor 13.
Solar vacuum tube collector described in the utility model 1 adopts the non-pressure-bearing union pipe of ridge type heat collector, installs simply, and can realize and the combining of roof, and does not influence the attractive in appearance of building; Storage tank adopts the horizontal storage tank 2 of the insulation of special no vacuum tube, is placed in the loft or top layer; Horizontal storage tank 2 is connected into an integral body with solar vacuum tube collector 1, adopts water pump forced circulation operation mode.Temperature controller 3 control whole system fully automatic operations.Temperature difference circulating pump 4 adopts canned motor pump, reliable in quality, and noise is little.Pipeline and accessory are original-pack integrated, guarantee the reliable of whole system.
Operation principle of the present utility model:
Under the fine situation of weather, as shown in Figure 1, vacuum tube solar heating element 1 absorbs solar energy raises the water temperature in the heat collector, satisfy to open and set when requiring when temperature controller 3 detects the temperature difference between the water-temperature water-level sensor 9 of heat collector sensor 10 and horizontal storage tank 2, control temperature difference circulating pump 4 starts, make vacuum tube solar heating element 1 and horizontal storage tank 2 carry out heat exchange, when satisfying to close, the temperature difference sets when requiring, controlling temperature difference circulating pump 4 again stops, thereby the water in the horizontal storage tank 2 is heated up, to reach the requirement of use.
Water solenoid valve 6 is gone up in temperature controller 3 control can realize the automatic loading water function: the water level when water-temperature water-level sensor 9 detects horizontal storage tank 2 in is lower than to be set when opening water level, and temperature controller 3 controls are gone up water solenoid valve 6 and opened, and closes water level and stops up to reaching setting; Water temperature is higher than and set opens temperature and water level and be lower than and set when opening water level in water-temperature water-level sensor 9 detects horizontal storage tank 2, and temperature controller 3 controls are gone up water solenoid valve 6 and opened, and closes water level or setting and closes water temperature and stop up to reaching to set.
Temperature controller 3 control electrical auxiliary heaters 7 are realized intelligent electric heating function: when the water temperature in water tank temperature sensor 12 detects horizontal storage tank 2 is lower than 5 ℃ of design temperatures, temperature controller 3 is opened auxiliary electrical heating 7, begin heating, when temperature reaches design temperature, stop.
When the temperature of thermal-arrest sensor 10 is higher than 95 ℃, and can not carry out temperature difference circulation time between vacuum tube solar heating element 1 and the horizontal storage tank 2, temperature controller 3 will be opened temperature difference circulating pump 4 and continue to stop 10 minutes again in 10 minutes, and circulation is carried out.When the temperature of antifreeze cycle sensor 13 is lower than in 5 ℃, temperature controller 3 will be opened temperature difference circulating pump 4 and stop when reaching 10 ℃.
When the temperature of pipeline cycle sensor 11 is lower than when setting 5 ℃ of pipeline circulating temperatures, temperature controller 3 control pipeline circulating electromagnetic valves 8 are opened, hot water booster pump 5 is opened automatically, begin to carry out the pipeline circulation, when reaching setting pipeline circulating temperature, pipeline circulating electromagnetic valve 8 is closed, and hot water booster pump 5 cuts out automatically.
Can realize full-automatic intelligent operation because of the utility model product, have the hot water amount of super large, can guarantee to use relieved, bathing is comfortable, and cost is lower simultaneously, and reliable in quality is convenient to marketing.
Above-described embodiment, the utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
