Description
Technical field
The utility model relates to a kind of solar water heater defroster.
Background technology
Prior solar water heater, standing in its water tank have an electric heater, except when overcast and rainy water temperature is low, starting electric heater, guarantee outside the hot water supply, but this electric heater also the antifreeze electric heater of double as use; And for split type solar water heaters such as balcony formulas, because heat collector and water tank are placed apart, so the electric heater in the water tank can not guarantee that heat collector can be not freezing.
In the patent No. is disclosed a kind of solar water heater and solar thermal collector of vacuum heat collection tube built-in metal heat-conducting pipe in 200910304345.5 thermal-collecting tube, solar thermal collector and the solar water heater, promptly has the problems referred to above; During winter easily because of the water freezing in the metal heat-conducting pipe, freezing metal heat-conducting pipe.
Summary of the invention
The technical problems to be solved in the utility model is that prior solar water heater can not guarantee the problem that heat collector can be not freezing.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of solar water heater defroster comprises heat collector, heat storage water tank, control system and circulating line; Heat storage water tank is positioned at the top of heat collector, is provided with runner in the heat collector, and circulating line is between heat storage water tank and heat collector, and two ends are connected with heat storage water tank and runner respectively; Also be provided with temperature measuring equipment in the heat collector, control system links to each other with temperature measuring equipment, also is provided with heater in the heat collector, and heater links to each other with control system, and the conducting temperature that control system is set is greater than 0 ℃.
Heat collector is collected solar radiant energy and is translated into heat energy, is used to heat the water in the heat collector; Water in the heat collector stores delivery by free convection in the heat storage water tank with heat insulation function, cover cold water simultaneously automatically; When the water temperature that records when temperature measuring equipment is colder, the heating of control system control heater, thus keep water temperature greater than 0 ℃, reach the purpose that prevents that heat collector is freezing.Described control system adopts existing control appliance in the prior art.
For further strengthening the antifreezing effect of solar water heater, heater and temperature measuring equipment all are positioned at the runner bottom, and the conducting temperature that control system is set is 4-6 ℃.Because the density maximum of water in the time of 4 ℃, when water temperature was greater than or less than 4 ℃, the density of water all can diminish, therefore, after 4 ℃ water were by the heating of the heater of bottom, hot water promptly can float because of density diminishes, and the cold water that is positioned at about 4 ℃ on top is bigger because of density, meeting automatic stream bottom; Simultaneously, for preventing that measured deviation from causing that actual conducting water temperature is lower than 4 ℃, therefore conducting temperature operated by rotary motion value is a little more than 4 ℃, thereby guaranteed that effectively the interior water temperature of heat collector is greater than 4 ℃, prevented the local temperature height of close heater in the runner, the phenomenon still icing away from the place of heater occurs.
Be the power consumption, the saving use cost that reduce heater, described control system also is set with break-off signal, and break-off signal is between 6-15 ℃.When the water temperature in the heat collector all reaches outage temperature that controller sets when above, can guarantee that heat collector can be not freezing, at this moment, electric heater cuts off the power supply automatically, can effectively avoid unnecessary power consumption, saves user's use cost.
As a kind of improvement project of the present utility model, be provided with secondary heater in the heat storage water tank, secondary heater links to each other with control system.When extraneous sunlight is not enough to support water heater water is heated to when needing temperature, secondary heater can play the effect that guarantees the hot water supply, but the antifreeze electric heater of double as is used in addition.
The utility model has the advantages that: simple in structure; Resistance to frost is good, has promptly overcome can not guarantee the shortcoming that heat collector is freezing in the prior art; Power consumption is few.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, heat storage water tank 1 is positioned at the top of heat collector 8, is provided with runner 3 in the heat collector 8, and circulating line 2 is between heat storage water tank 1 and heat collector 8, and two ends are connected with heat storage water tank 1 and runner 3 respectively; Also be provided with temperature measuring equipment 4 in the heat collector 8, control system 7 links to each other with temperature measuring equipment 4, also is provided with heater 5 in the heat collector 8, and heater 5 links to each other with control system 7; Heater 5 and temperature measuring equipment 4 all are positioned at runner 3 bottoms, and the conducting temperature that control system 7 is set is 5 ℃, and break-off signal is 15 ℃.
Existing heat collector divides two parts: a part is a thermal-collecting tube, promptly is used to absorb solar radiation; A part is a runner 3; Connect by heat pipe 6 between the two, make the solar radiant energy that absorbs in the thermal-collecting tube be converted into heat energy in the water; Runner is divided into upper runner 3-1 and lower flow channel 3-2, and upper runner 3-1 stores the delivery that heats by the top of circulating line 2 connection heat storage water tanks 1 in heat storage water tank 1; Lower flow channel 3-2 is used for replenishing the cold water of runner 3 by the bottom of circulating line 2 connection heat storage water tanks 1.When being not enough to add water temperature that water in the hot flow path 3 and temperature measuring equipment 4 record and being lower than 5 ℃ by heat collector 8, heater 5 is the conducting heating, prevents the frostbite heat collector when overcast and rainy; When water temperature rose to 15 ℃, heater 5 disconnected, and stops heating, reaches the purpose of energy efficient.
