Abstract
The invention relates to an emergency cooling protection system of a solar thermal collector. The emergency cooling protection system of the solar thermal collector comprises the solar thermal collector; a heating medium circulation pipeline between the inlet and the outlet of the solar thermal collector is provided with a heat exchanger; the heat exchanger is connected to domestic hot water supply circulation pipeline; the outlet end, close to the solar thermal collector, of the heating medium circulation pipeline is provided with a heating medium circulation pump; the emergency cooling protection system of the solar thermal collector further comprises an emergency cooling device; the emergency cooling device uses the air as a refrigeration source; and the inlet pipeline of the emergency cooling device communicates with the heating medium circulation pipeline between the heating medium circulation pump and the solar thermal collector. The emergency cooling device is used for releasing the excessively absorbed solar energy to the air. The excess heating medium temperature in the solar thermal collector is prevented to cause the crack, so that the heating medium temperature is kept within certain range.
Description
Technical field
The present invention relates to a kind of solar thermal collector, particularly relate to the urgent cooling protection system of a kind of solar thermal collector.
Background technology
Utilizing in solar energy production hot water process, because solar energy is uncontrolled, traditional design be heating agent through solar thermal collector, absorb solar energy and heating after be sent to heat exchanger heat exchange, such as water is heated, after heat exchange cooling, be back to solar thermal collector again.Wherein, after being reached design temperature by heat hot water, heating agent does not recycle, and because solar energy is uncontrolled, continue heating solar heat-collector, the heat medium temperature in heat collector is too high, easily causes the drawbacks such as heat collector explosion and heating agent pipeline cracking.
Summary of the invention
In order to solve the drawback such as heat collector explosion and heating agent pipeline cracking in traditional design, the invention provides following technical scheme:
The urgent cooling protection system of a kind of solar thermal collector, it comprises solar thermal collector, the heating agent circulation line exporting between import of described solar thermal collector is provided with heat exchanger, described heat exchanger connects domestic hot-water's watering cycle pipeline, described heating agent circulation line is provided with heat medium circulation pump at the port of export near described solar thermal collector, it is characterized in that, also comprise an emergency cooling device, described emergency cooling device is using air as refrigeration source, the inlet ductwork of described emergency cooling device is communicated with the heating agent circulation line between described heat exchanger and described solar thermal collector, the inlet ductwork of described emergency cooling device is communicated with the heating agent circulation line between described heat medium circulation pump and described solar thermal collector.
Preferably, the import of described emergency cooling device and the connecting pipeline of described heating agent circulation line are provided with the first magnetic valve, the outlet of described emergency cooling device and the connecting pipeline of described heating agent circulation line are disposed with coolant circulation pump, check-valves and the second magnetic valve.
Preferably, described heating agent circulation line upper pipeline is communicated with an expansion drum.
Preferably, described expansion drum is arranged between described heat medium circulation pump and described solar thermal collector.
The beneficial effect that the present invention reaches: the present invention increases by one group of emergency cooling device in the system utilizing solar energy production hot water---the heat pump of certain special shape, urgent refrigerating plant is used in enclosed pressure bearing system, only be connected with heating agent confession, return pipe road, directly do not contact with domestic hot-water, preventing pollution domestic hot-water.After being reached design temperature by heat hot water, solar thermal collector still absorbs solar energy, now emergency cooling device starts, heating agent pipeline is no longer through over-heat-exchanger, but directly by urgent refrigerating plant, the solar energy of excessive consumption is released in air by emergency cooling device, to prevent the too high initiation explosion of the heat medium temperature in heat collector, thus heat medium temperature is remained in certain scope.Refrigerating plant does not participate in cooling and the heat supply of system at ordinary times, energy-conservation and make full use of solar energy with maximum possible.
Accompanying drawing explanation
Fig. 1 is the structural representation of the urgent cooling protection system of solar thermal collector of an embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, introduction detailed is further done to the present invention.
As shown in Figure 1, the urgent cooling protection system of a kind of solar thermal collector of the present invention comprises solar thermal collector 1.The heating agent circulation line 2 exporting between import of solar thermal collector 1 is provided with heat exchanger 3, and heat exchanger 3 connects domestic hot-water's watering cycle pipeline 4, and heating agent circulation line 2 is provided with heat medium circulation pump 6 at the port of export near solar thermal collector 1.In order to avoid after hot water heating to assigned temperature, the out-of-work problem of hot recycle pump, invention increases an emergency cooling device 7, emergency cooling device 7 is using air as refrigeration source, the dissipate heat now solar thermal collector 1 produced in air, thus effectively avoids the situations such as solar thermal collector 1 explosion to occur.In order to the circulation of reasonable arrangement fluid, the inlet ductwork of emergency cooling device 7 is communicated with the heating agent circulation line 2 between heat exchanger 3 and solar thermal collector 1, and the inlet ductwork of emergency cooling device 7 is communicated with the heating agent circulation line 2 between heat medium circulation pump 6 and solar thermal collector 1.The import of emergency cooling device 7 and the connecting pipeline of heating agent circulation line 2 are provided with the first magnetic valve 8, the outlet of emergency cooling device 7 and the connecting pipeline of heating agent circulation line 2 are disposed with coolant circulation pump 9, check-valves 10 and the second magnetic valve 11.First magnetic valve 8 and the second magnetic valve 11 at heat exchanger 3 still operationally, are in closed condition; When heat exchanger 3 quits work, then the first magnetic valve 8 and the second magnetic valve 11, coolant circulation pump 9 is also opened simultaneously, is formed by the closed circuit between solar thermal collector 1 and emergency cooling device 7, is distributed in time by the heat that solar thermal collector 1 produces.
Further, heating agent circulation line 2 upper pipeline is communicated with an expansion drum 12.
Further, expansion drum 12 is arranged between heat medium circulation pump 6 and solar thermal collector 1.
Above-described embodiment does not limit the present invention in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection scope of the present invention.
