Abstract
The utility model discloses an automatic emptying devices of flat plate solar collector, at row empty can of circulation fluid import series connection of coiled flat plate solar collector lower extreme two -way motorised valve of cold water end of lower extreme connection of row empty can two -way motorised valve of hot water end of outlet of circulation hydraulic series connection of coiled flat plate solar collector upper end. The utility model discloses an automatic emptying devices of flat plate solar collector makes dull and stereotyped solar energy can make things convenient for in winter, reliably, and water in the emptying heat collector prevents that the heat collector is by freezing. Convenient operation, it is with low costs.
Description
Technical field
The utility model relates to a kind of flat-plate solar collector automatic emptier, belongs to the manufacturing field of equipment of Solar use.
Background technology
Flat panel solar heat collecting system is when applying winter, antifreeze is a big difficult problem, if adopting deicing fluid as heat-conducting medium, so system is safe, but has two big shortcomings, the first increase cost, need heat exchanger and deicing fluid, once there is pipeline problem, deicing fluid just flows to end, and causes loss; Two-way over-heat-exchanger indirect heating, reduces system thermal efficiency. If employing direct heating, it does not have the problems referred to above, result is the emptying work being a trouble and endangering after adopting heat, just in case not to the utmost emptying, cause heat collector freezing, suffer heavy losses. If easy and emptying problem completely can be solved, so there is positive help to during the application of panel solar.
Practical novel content
The technical problems to be solved in the utility model overcomes existing defect, it provides a kind of flat-plate solar collector automatic emptier, make panel solar winter can facilitate, reliably, the water in emptying heat collector, prevents heat collector freezing.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of flat-plate solar collector automatic emptier, under coil tube type flat-plate solar collector, the circulation fluid import of end is connected a drain tank, lower end in described drain tank connects a cold water end bidirectional electric valve, the circulation fluid outlet series connection hot water end bidirectional electric valve in described coil tube type flat-plate solar collector upper end.
In such scheme preferably, the first state of described bidirectional electric valve is used for normally adopting heat, and two-state is used for emptying.
In above-mentioned either a program preferably, the A1 mouth of the described two-way valve of hot water end is connected on normal operation loop, and B1 mouth is that sky is open; The A2 mouth of the described two-way valve of cold water end is connected on normal operation loop, and B2 mouth is connected in the water at low temperature outlet of water tank.
In above-mentioned either a program preferably, the A2 mouth of the described two-way valve of cold water end is connected on circulation pump outlet, and B2 mouth is connected in the water at low temperature outlet of water tank, pipeline liquid when receiving emptying.
The beneficial effects of the utility model: flat-plate solar collector automatic emptier of the present utility model, make panel solar winter can facilitate, reliable, the water in emptying heat collector, prevents heat collector freezing.Easy to operate, cost is low.
Accompanying drawing explanation
Fig. 1 is the structural representation of a preferred embodiment of a kind of flat-plate solar collector automatic emptier of the utility model.
Embodiment
Hereinafter preferred embodiment of the present utility model is described, it will be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and is not used in restriction the utility model.
Embodiment 1:
