Solar cell receives the radiant energy of sunshine, is translated into direct current energy, the required electric energy of parts such as variable speed compressor, controller all thus solar cell provide.Master switch is used for cutting off the power supply of whole refrigerating plant when not using refrigerating plant of the present invention.
Under the situation of abundance at sunshine, connect master switch, if the temperature in the casing is higher than the temperature value that controller is set, refrigeration system will be started working.By the refrigerant gas of the HTHP after the variable speed compressor compression, in condenser, be condensed into liquid, flowing through then behind the device for drying and filtering in throttling arrangement by the throttling step-down is the liquid (generally being the gas-liquid two-phase cold-producing medium that has a small amount of flash steam) of low-pressure low-temperature, cold-producing medium evaporates in evaporimeter afterwards, cold-producing medium absorbs the heat in the casing, thereby the temperature of refrigerator is reduced to the temperature of setting, come out from evaporimeter, absorbed the low-temperature low-pressure refrigerant of heat in the casing, come back to variable speed compressor, be compressed into the gas of HTHP once more, like this reciprocation cycle.When the temperature in the casing has arrived the lowest temperature value of setting, controller will cut off the power supply of variable speed compressor, after a period of time, and when the temperature recovery in the casing during to the temperature upper limit set, controller is connected the power supply of variable speed compressor, and refrigeration system is task again.Be provided with blower fan in the outdoor version refrigerating plant of the present invention, its effect is the cold-producing medium of forcing in the cooler condenser.Pressure switch is work like this: when moving in the winter time, condensing pressure may be very low, at this moment pressure switch will be cut off the power supply of blower fan, when condensing pressure goes back up to certain value, pressure switch is connected blower fan, blower fan reruns, thereby guarantees the degree that condensing pressure is unlikely to be reduced to influences the refrigeration system operate as normal.
Tank wall and chamber door are the building enclosures of casing; the outer wall of tank wall plays supporting box and protection heat-insulation layer; the cold-storage inner bag is protected heat-insulation layer on the one hand; play the effect of cold-storage on the other hand; specifically: there is high latent heat of phase change cool storage material the inside of cold-storage inner bag; in the sunshine abundance; the superfluous relatively cold that refrigeration system produces is stored in the cool storage material in the cold-storage inner bag; then when night or rainy weather; cool storage material discharges the temperature that is used for keeping refrigerator with cold, so just can realize the continuous operation of refrigerator at night or rainy weather.Annex is the parts of establishing in order to put convenient grade of goods.
Photoelectric follow-up is work like this: the photoelectric tracking inductor that induction solar radiation direction is housed on solar cell, and the signal that the photoelectric tracking inductor is sensed passes to controller, controller drives photoelectric tracking executing agency according to this signal, with the angle of the horizontal direction of regulating solar cell and the inclination angle of vertical direction, thereby the surface that guarantees solar cell absorption sunshine is perpendicular with the radiation direction of sunshine all the time, to absorb solar radiant energy to greatest extent.
The direct current compressor governing system is work like this: controller is according to the signal of solar cell electric energy power sensor, regulate the rotating speed of variable speed compressor, thereby the electric energy power that produces at solar cell hour, such as morning and dusk, refrigeration system can be worked equally, so just can make full use of solar energy.
The present invention adopts cold-storage technology, photoelectric tracking technology and refrigeration compressor speed adjusting technique, can make full use of clean renewable energy solar energy, but be compared to existing photovoltaic and drive refrigerating plant expectation energy savings 30%, in addition, owing to do not have battery in the refrigerating plant of the present invention, the weight of equipment significantly reduces, and drive refrigerating plant weight than the present photovoltaic of being furnished with battery and reduce about 50%, and the pollution to environment that is brought when not having battery to scrap.The present invention utilizes blower fan, guarantees the degree that condensing pressure is unlikely to be reduced to influences the refrigeration system operate as normal.The present invention applies to photoelectric tracking technology, dc speed-changing compressor speed adjusting technique and cold-storage technology in the refrigeration systems such as refrigerator, air-conditioning, freezer.Refrigeration of medical articles such as this refrigerating plant can be widely used in not having electrical network, the food fresh keeping of power-shortage area (as remote mountain area, nomadic area etc.) and vaccine blood plasma etc.
