Description
技术领域technical field
本发明属于太阳能技术领域，尤其涉及一种太阳能管道防冻装置及方法。The invention belongs to the technical field of solar energy, and in particular relates to a solar pipeline antifreeze device and method.
背景技术Background technique
传统的太阳能热水器进出水管道，虽然在其外侧壁设有保护材料，但由于严冬温度过度低，往往还会发生冻结甚至引起水管爆裂，使得热水不能正常使用。Although there are protective materials on the outer wall of the traditional solar water heater inlet and outlet pipes, due to the excessively low temperature in severe winter, it often freezes or even causes the water pipes to burst, making the hot water unable to be used normally.
现有技术中，部分使用者为了在严冬也能正常使用太阳能热水器，只能对太阳能热水器重新改造，安装太阳能管道防冻装置。In the prior art, in order to normally use the solar water heater in severe winter, some users have to remodel the solar water heater and install a solar pipeline antifreeze device.
常见的太阳能管道防冻装置有以下三种：双管虹吸防冻循环装置、伴热带装置和排空阀装置。上述三种装置均存在诸多不足：一、在太阳能热水器管道上安装双管虹吸式防冻循环装置，虽然在冬天可以解决太阳能管道防冻的问题，但是在虹吸过程中会消耗太阳能热水器白天吸收的部分热能，使得太阳能储水箱水温下降。如果碰到阴天连续的情况，该管道仍可能会发生冻结。而且对于老式的太阳能热水器改造，不仅需要重新铺管，损坏装修好的房子，而且效果不好。二、在太阳能热水器管道上安装在电热丝(伴热带)装置，在冬天通过加热来防止冻结，但是在实际过程中消耗了大量的电能。而且对于老式单管太阳能，需要拆管布线，甚至损坏装修好的房子。三、在太阳能热水器管道上安装排空阀装置，通过在管道中加管道排空阀，将管道的水抽去。该方案既能解决结冰问题，也能解决出水即热问题，但是需要进行重新布线，安装很不方便，且安装成本较高。There are three common antifreeze devices for solar pipelines: double-pipe siphon antifreeze circulation device, heating belt device and emptying valve device. All there are many deficiencies in the above-mentioned three kinds of devices: one, double-pipe siphon type antifreezing circulation device is installed on the solar water heater pipeline, although the problem of antifreezing of solar pipeline can be solved in winter, but can consume the part heat energy that solar water heater absorbs during the day in the siphon process , making the water temperature of the solar water storage tank drop. In the event of continuous cloudy weather, the pipeline may still freeze. Moreover, for the retrofit of old-fashioned solar water heaters, not only does it need to re-lay pipes, but it will damage the renovated house, and the effect is not good. Two, the heating wire (heating cable) device is installed on the solar water heater pipeline, and prevents freezing by heating in winter, but consumes a large amount of electric energy in the actual process. And for the old-fashioned single-tube solar energy, it is necessary to dismantle the tube and wiring, and even damage the renovated house. 3. Install an emptying valve device on the pipeline of the solar water heater, and pump out the water in the pipeline by adding a pipeline emptying valve in the pipeline. This solution can not only solve the problem of icing, but also solve the problem of hot water when it comes out, but it needs to be rewired, and the installation is very inconvenient and the installation cost is relatively high.
再者，上述三种方法均为利用了手动进行管道排空装置的方法，假如用户忘记排空管道，该太阳能热水器管道仍会结冰。Moreover, above-mentioned three kinds of methods all are to have utilized the method for manually carrying out pipeline emptying device, if user forgets to empty pipeline, this solar water heater pipeline still can freeze.

用于采集水流计信号，与第二信号控制箱协商排空需要，并控制三通阀开启或闭合的第一信号控制箱；The first signal control box is used to collect the water flow meter signal, negotiate with the second signal control box on the need for emptying, and control the opening or closing of the three-way valve;
用于采集水压计信号，与第一信号控制箱协商排空需要，并控制二通阀开启或闭合的第二信号控制箱；The second signal control box is used to collect the water pressure gauge signal, negotiate with the first signal control box on the need for emptying, and control the opening or closing of the two-way valve;
进一步地，所述三通阀一端与储水箱连接，一端与空气连接，另一端与输水管道连接。三通阀的任意两端可配合使用，达到为储水箱进水或使输水管道内水流回流的作用。Further, one end of the three-way valve is connected to the water storage tank, one end is connected to the air, and the other end is connected to the water pipeline.
