Abstract
The invention discloses a flat-panel solar heat collector. The flat-panel solar heat collector is characterized in that the heat collector is provided with a gas-liquid separator and an electromagnetic valve, the temperature and pressure of outputted medium gas can be controlled, and steam-spraying cooling efficiency is guaranteed to be maintained at an optimal state.
Description
One, technical field
The present invention relates to solar energy heat utilization field, refer in particular to a kind of flat-plate solar collector, this solar thermal collector has gas-liquid separator and magnetic valve, can control the pressure and temperature of output medium, is suitable as the thermal source of steam-jet refrigerating system.
Two, background technology
Solar water heater is that a kind of solar energy that utilizes is as the helioplant of energy sources for heating water or heat transfer medium.The most representative with vacuum tube type solar energy water heater and plate solar water heater in existing solar water heater product.Vacuum tube collector heat sink is vacuum tube, and heat loss is little.Compare with vacuum tube type solar energy water heater, that plate type solar water heater has is simple in structure, sunlight footprint is large, seal request is low, it is antifreeze not need, working medium is cheap, respond the advantages such as fast.But also there is the shortcomings such as heat loss is large, collecting efficiency is low.
The freeze temperature and pressure of required thermal source of simultaneous steam injection formula is all lower, by rational selection working medium and design runner, can use solar thermal collector as thermal source.For reaching this purpose, traditional flat-plate solar collector can be improved, design and a kind ofly can control the gas medium temperature of output and the solar thermal collector of pressure.
Three, summary of the invention
The object that the present invention proposes is to design a kind of flat-plate solar collector, the gas medium temperature of its output and pressure can be controlled, to adapt to the needs of steam-sprayed refrigeration.
For achieving the above object, the present invention adopts following technical scheme:
A kind of flat-plate solar collector, its structure is comprised of housing, transparent cover plate, snake bend, absorber plate, ascending tube, up magnetic valve, gas-liquid separator, outlet, return duct, down pipe, downlink electrical magnet valve, wherein absorber plate is welded on snake bend near a side of transparent cover plate, form absorber, the upper end of snake bend is connected with ascending tube, and lower end is connected with down pipe.Up magnetic valve is arranged on ascending tube, controls the outflow of the rear gas of heat absorption, after opening, can only upwards pass through, and downlink electrical magnet valve is arranged on down pipe, after opening, can only pass through downwards, and the backflow of liquid after control condensation.Ascending tube connects gas-liquid separator, and the mouth of pipe is positioned at below the metal line of gas-liquid separator, and gas-liquid separator top is provided with outlet, and bottom is provided with return duct, and return duct connects down pipe, and its coupling part, according to gas flow, before downlink electrical magnet valve.In absorber, be full of boiling point at the low-boiling point liquid of 30 to 50 degrees Celsius as working media.
By adopting temperature and pressure transmitter to control the switching of magnetic valve, can control gas temperature and the pressure of flat-plate solar collector output, guarantee that the efficiency of steam-sprayed refrigeration is always in optimum state.
Four, accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is the schematic appearance of this device.
Fig. 2 is this device absorber back view.
In figure, the position of marking is respectively: 1, housing; 2, transparent cover plate; 3, snake bend; 4, absorber plate; 5, ascending tube; 6, up magnetic valve; 7, gas-liquid separator; 8, outlet; 9, return duct; 10, down pipe; 11, downlink electrical magnet valve.
Five, the specific embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention are explained.
