Description
Affiliated technical field
The utility model relates to the moisturizing of solar water heater automatic constant-pressure, double pipe evacuation and anti-freezing, and a kind of " constant voltage top ability of swimming double pipe evacuation and anti-freezing solar water heater " is provided.
Background technology
As everyone knows, solar energy is tellurian omnipotent mother, is inexhaustible, nexhaustible clear energy sources.Solar water heater is a kind of efficient apparatus that directly solar energy is converted to heat energy.At present, solar water heater has entered huge numbers of families, and domestic only solar water heater manufacturer just has more than thousands of families, but the solar water heater product that all producers produce, be the non-pressure-bearing of the opening formula product that falls into water more than 95%, a spot ofly be the pressure-bearing type product of remaining silent.The drowning formula product of the non-pressure-bearing of so-called opening, be to have the porting that communicates with atmosphere on the heat-preserving water tank for solar water heater, disposable attemperater filled with cold water, close water supply valve, after the solar irradiation heating, flow out use by the delivery port that is in the attemperater bottom.Because solar water heater generally all is installed in the top in house, and the long upper and lower waterpipe that is in the outdoor environment is in full water state all the time.When using hot water, after at first needing to drain cold water more in the sewer pipe, just can use hot water, this has not only wasted a lot of water resources, and brings inconvenience to use.Interim when winter of cold, because upper and lower waterpipe or do not have heat insulation function or heat insulation function is not good causes the water in the upper and lower waterpipe to be frozen to block fully, cause solar water heater normally to use.At present, the described in-problem technical scheme of existing solution is: 1, carry out the insulation of upper and lower waterpipe; But the cost of doing insulation is very high, and construction is difficult, and still need drain ducted cold water before using hot water; 2, at the electronic or electromagnetism exhaust-valve of warming solar energy water outlet of water tank place device; But this device not only involves great expense, and because the safety factor of the unstable and power supply that uses of each electronic component itself makes this scheme exist potential safety hazards such as malfunctioning; 3, adopt three to connect valve top ability of swimming double pipe evacuation; Though need drain the drawback of cold water when this scheme has solved with hot water earlier, but because the variation that the water drop does not wait under the continuous variation of tap water hydraulic and the story height during last water, cause upper and lower water discharge to be difficult to balance: when the discharge of last water during greater than the discharge of water outlet, the water in the heat-preserving water tank for solar water heater will overflow; When the discharge of last water during less than the discharge of water outlet, when using hot water the not smooth phenomenon of current will appear; And, though this technical scheme at that time can double pipe evacuation, but because the warming solar energy water tank is in full water state, next day, the water in the attemperater under solar irradiation after the solar thermal collector heating, the hydrone gap increases, volume constantly expand (according to 60 ℃ of calculating of full-time temperature rise, the volume of water increases 2-3% approximately, the water yield of the 2-3% that promptly will overflow), calculate by 100 liters attemperaters, slowly spill-over goes out the water of about 2-3 liter among upper and lower waterpipe.If in the winter of cold, the water yield that so slow spill-over goes out is enough to upper and lower water pipe is frozen stifled, thereby has lost the practical significance of emptying.
In sum, understand according to the inventor, " flat solar water heater " and " vacuum heat-collecting tubular type solar water heater " two generations product that China releases afterwards from " passive solarenergy water heater " is over nearly 50 years, but users are always at the solar water heater product of expecting technology maturation, dependable performance, stable permanent, easy to use, cheap two-tube emptying.The producer of numerous research and development solar energy, tissue and individual have also paid a large amount of hard-workings for this reason, and once release generation by generation panoramic double pipe evacuation technology and product, but all fail " breaking " this layer " window paper " because of the deviation of thinking.
