The pressure can be automatically boosted during the bathing.
Description
Technical field
The utility model relates to solar water heater, refers to that specifically a kind of heat collector is higher than water tank partial installation, the non-formula solar water heater that holds
Background technology
Solar water heater just more and more is subjected to liking of people as a kind of clean pollution-free green environmental protecting device.At present, popular on the market solar water heater mostly is combined or pressure wall-mounted.The main composition form of combined is that water tank is associated in vacuum tube; The metal tube by a sealing is associated between the vacuum tube of heat collector and the water tank though pressure wall-mounted formation water tank separates with heat collector.The operation principle of combined is: glass tube with vacuum is accepted the irradiation of sunlight, the interior water of pipe is heated heats up and buoyance lift, and the water circulation heat-shift with in the attemperater reaches the intensification of whole water.Exist following defective from structure and this solar water heater of heat exchange pattern:
One, glass tube with vacuum and attemperater are integrated, shared space is very big, the live load of water inlet back water heater is also very big, significant limitation is arranged laying on the place like this, thereby form and often to have only attic resident family just can install and use solar water heater, all the other users think that dress all can't install or use.
Since the limitation of the daylighting of combined solar water heater, the limitation of the big installation of volume, thus cause the installation of solar water heater often to influence the attractive in appearance and integrated of urban architecture, and meanwhile, non-top layer user's installation is with
One, the social concern of initiations such as the safety of coming, percolating water is led and has been made the restriction to solar water heater of local administration departments and departments of government.
Two, the heat exchange of water is the exchange of carrying out in single body pipe naturally in the glass tube with vacuum, and under the not high situation of temperature, the speed that this heat exchange is transmitted is very slow, and heat exchanger effectiveness is very low.
Three, because water tank is associated in vacuum tube, and water tank is above vacuum tube, thus the water in the vacuum tube be forever can't reflow tank for use.
Four, solar water heater is placed on outdoor, and the heat dissipation capacity of water tank is very big, and under severe winter, the low temperature low light shone (as evening), the water in the vacuum tube easily build-ups ice, thereby with the vacuum tube bursting by freezing.
Five, there is hydropexis the glass tube with vacuum midium or long term, it is again the nature exchange, therefore the trash in the water is very easy to precipitation, time has a lot of BSWs dirts once length and produces, unless vacuum tube is disassembled just can finish and remove these sediments or incrustation scale, this has hindered the absorption of solar energy to a great extent.
The operation principle of pressure wall-mounted solar water heater is: glass tube with vacuum is accepted the irradiation of sunlight, metal tube in the radiant energy heating, vacuum pipe that is produced, heat-conducting medium in the metal tube is heated up or vaporization, thereby shift to water tank, in water tank, thermal energy transfer is fed water, sink to flowing back to vacuum tube after the medium cooling and be heated again, so continuous reciprocation cycle, the water in the heating water tank.Exist a very big problem from structure and this solar water heater of heat exchange pattern: owing to need to increase the metal tube of a closed circulation, and water tank needs pressure-bearing type, on the water heater material cost, increase 3-5 training so at least, also can correspondingly increase to consumer's retail price.
Summary of the invention
The purpose of this utility model will solve above-mentioned the deficiencies in the prior art exactly, provide a kind of install freely limit less, compulsory type thermal efficiency of cycle height, water tank and install heat collector split indoor and outdoor, be difficult for the bursting by freezing vacuum tube winter, hot water reflux tank in the vacuum tube, moderate solar water heater.
For realizing this purpose, the non-pressure-bearing separated type solar water heater that the utility model is designed comprises attemperater arranged apart, heat collector, circulating pump, control valve, reflux etc.This attemperater is the non-bearing type water tank, and the water level temperature sensor is installed in the water tank.Heat collector is made up of many glass tube with vacuum lateral arrangement; In the coupling device that connects the subtend vacuum tube, be furnished with a female pipe; Be provided with arm in the vacuum tube.Solar thermal collector is by water tank, circulating pump, shared pipe and magnetic valve, uniguide and check-valves, female aqueduct form circulation, return-flow system up and down.
The invention has the advantages that:
One, heat collector and water tank partial installation, heat collector can be incorporated into one with building such as awning, and free, autonomous multifunction not only is installed, and both can shelter from sunshine as awning and keep off the rain, but be again the water heater of heat supply water.
Two, because solar water heater and traditional buildings such as awning are incorporated into one, solar water heater can combine as a whole with building, therefore do not influence the attractive in appearance and integrated of building, because solar water heater is installed on oneself balcony, can avoid thus producing the social concern that causes such as problems such as safety, percolating waters simultaneously because of solar water heater is installed;
Three, the formation of female pipe arm can allow up cold water begin to carry out hot water or cold water's exchange from the cecum bottom of vacuum tube, and the circulation of each compulsory type is very thorough thus, and its thermal efficiency is greatly improved;
Four, water tank and heat collector partial installation, and the heat collector position is higher than water tank, therefore by reflux, fully can with the water in the heat collector by the drop natural back flow to water tank for use, the thermal efficiency of solar water heater directly can improve about 30% like this;
Five, under normal circumstances water tank all is placed on indoor, indoor air themperature generally all remains under the basic weighing apparatus temperature state about 20 degrees centigrade, therefore the heat waste of water tank is much smaller a lot of with respect to outdoor, fail to reach under certain value light intensity (as the evening) situation owing to having arrived illumination simultaneously, the water reflux tank in the vacuum tube, therefore, no matter how how low temperature is, also can the bursting by freezing vacuum tube;
Water in six vacuum tubes is in the exchange of often flowing, so the difficult precipitation of the trash in the water, also is difficult for influencing the absorption of solar energy;
Seven owing to need not increase sealing precious metal circulation line, thus its price and conventional desktop almost, the consumer easily accepts;
