A kind of transformer oil that this utility model design provides is as the control recovery system of PV/T system circulatory mediator, it is characterized in that this control recovery system includes 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 controlling recovery system and also include fluid sensor and oil liquid alarming device, fluid sensor is arranged in fuel tank, and oil liquid alarming device is arranged on outside fuel tank, and fluid sensor 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.
This utility model has the advantages that
1, owing to this utility model have employed, to have freezing point low, the transformer oil of the features such as not-easy-to-freeze and specific heat is big is as circulatory mediator, thus can while ensureing that PV/T system has excellent heat dispersion performance, preventing the problem that heat collector and pipeline internal recycle medium freeze, the area being in less than 0 DEG C for the temperature throughout the year such as high latitude, High aititude uses PV/T system to provide possibility.
2, owing to this utility model not use only in PV/T system, to have freezing point low, the transformer oil of the features such as not-easy-to-freeze and specific heat is big is as circulatory mediator, and design provides a kind of control recovery system matched for it especially, thus can really realize the normal use in high latitude, the relatively low area of High aititude equitemperature of the PV/T system, the heat energy of the sun can be utilized, also can utilize the luminous energy of the sun, improve the utilization rate of its energy.
3, fluid sensor and oil liquid alarming device it are also provided with due to this utility model, when transformer oil is in use depleted to a certain degree, programmable logic controller (PLC) can receive the signal that fluid sensor transmits, alarm 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, owing to three-way magnetic valve, oil pump and oil liquid alarming device can be controlled by this utility model by the programmable logic controller (PLC) in control recovery system, thus control and the adjustment of on-line automaticization circulatory mediator can be achieved, improve the work operational efficiency of PV/T system.
