Description
Technical field
The invention belongs to the control recovery system technical field of circulatory mediator in helioplant, particularly a kind of transformer oil is as the control recovery system of PV/T systemic circulation medium.
Background technology
General solar photoelectric light-heat (PV/T) system is all adopt water to dispel the heat to solar panel as circulatory mediator, but the solidifying point of water is 0 DEG C at normal atmospheric pressure, thus the area of less than 0 DEG C is all in the long-term temperature such as high latitude, High aititude, the circulatory mediator used water as PV/T system easily freezes in heat collector and pipeline, thus can cause certain influence to the normal use of system.Thus lower ground now mostly vacuum tube collector is used in district at high latitude, High aititude equitemperature, but vacuum tube collector is not easy to PV/T system to be combined completely, cause the heat energy that can only utilize solar energy, and the luminous energy of the sun can not be utilized, reduce the utilance of the energy.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of transformer oil as the controlling and regulating system of PV/T systemic circulation medium, to improve the intensification efficiency of photovoltaic panel in PV/T system.
The present invention adopts water can not in the normal use problem in high latitude, High aititude equitemperature district lower as the PV/T system of circulatory mediator to solve, first consideration transformer oil substitutes the circulatory mediator that water is used as in PV/T system, because the solidifying point <-45 DEG C of transformer oil, not-easy-to-freeze, specific heat is large, while guarantee great heat radiation effect, also can solve PV/T systemic circulation medium in cold district---water can be frozen in the problem in heat collector and pipeline.But, because existing PV/T system is when ensureing photoelectric conversion efficiency and stable output, the optimum temperature of its work is about 25 DEG C, when lowering at night or cloudy temperature, lower (feature that the daily difference as Tibet temperature is large is obvious especially, noon daytime June can up to 27-29 DEG C, and midnight, temperature can be down to 5 degrees Celsius) and after PV/T system do not work, the words of transformer oil are also had in heat collector, when will make that second day daytime, PV/T system was just started working, the temperature of photovoltaic panel is not only lower and intensification is very slow (heating because also needing the transformer oil that will have in heat collector simultaneously), the photoelectric conversion efficiency of photovoltaic panel work will be caused in this case low, and export also unstable.In order to solve the problem because producing after substituting water with transformer oil simultaneously, just need the control recovery system designing a kind of transformer oil, to enable system the automatic recovery transformer oil under idle cryogenic conditions, and when making second day PV/T system starts, temperature can be risen to optimum temperature by heat collector as soon as possible.
The present invention designs a kind of transformer oil of providing control recovery system as PV/T systemic circulation medium, it is characterized in that this control recovery system comprises temperature sensor, programmable logic controller (PLC), three-way magnetic valve, oil circuit arm, oil pump and fuel tank, temperature sensor, three-way magnetic valve are connected with programmable logic controller (PLC) respectively with oil pump, oil circuit arm one end is connected with three-way magnetic valve, and the other end is communicated with fuel tank by oil pump.
More than control recovery system and also comprise fluid transducer and oil liquid alarming device, fluid sensor setting is in fuel tank, and oil liquid alarming device is arranged on outside fuel tank, and fluid transducer is connected with programmable logic controller (PLC) respectively with oil liquid alarming device.
During use, temperature sensor is arranged in the photovoltaic panel in PV/T system, and three-way magnetic valve is arranged in the circulatory mediator path of PV/T system.
The present invention has following beneficial effect:
1, owing to present invention employs, to have solidifying point low, the transformer oil of the features such as not-easy-to-freeze and specific heat is large is as circulatory mediator, thus can while guarantee PV/T system has excellent heat dispersion performance, prevent the problem that heat collector and pipeline Inner eycle medium freeze, the area being in less than 0 DEG C for the long-term temperature such as high latitude, High aititude uses PV/T system to provide possibility.
2, because the present invention not use only in PV/T system, to have solidifying point low, the transformer oil of the features such as not-easy-to-freeze and specific heat is large is as circulatory mediator, and special design for it provides a kind of control recovery system matched, thus the normal use of PV/T system in high latitude, High aititude equitemperature district lower can really be realized, the heat energy of the sun can be utilized, also can utilize the luminous energy of the sun, improve the utilance of its energy.
3, because the present invention is also provided with fluid transducer and oil liquid alarming device, when transformer oil is in use depleted to a certain degree, programmable logic controller (PLC) can receive the signal that fluid transducer transmits, warning device can be controlled by analysis and send alarm signal, thus transformer oil can be increased in time, to guarantee the normal operation of PV/T system.
4, because the present invention controls three-way magnetic valve, oil pump and oil liquid alarming device by the programmable logic controller (PLC) controlled in recovery system, thus can achieve control and the adjustment of on-line automaticization circulatory mediator, improve the work operational efficiency of PV/T system.
