Embodiment Construction
[0017] The photovoltaic power generation system uses concave solar panels. Due to the rise of the surface temperature of the solar panels and the characteristics of selective utilization of light, 80% of the solar energy is not converted into electrical energy. This system uses water pipes to cool the solar panels to reduce the surface temperature of the solar cells and improve its power generation efficiency to a certain extent; the concave reflective surface recycles the sunlight reflected by the solar panels through the heat collecting tubes to heat and cool the water, further Increase the temperature of the cooling water; the heated hot water is sent to the user for daily needs. The electricity generated by the solar panel is supplied to the dual-working condition refrigeration unit through the energy storage device, and the refrigeration work generated by the refrigeration unit is stored through the ice bucket water storage technology, so as to cool the room when cooling i...

The invention relates to a solar cogeneration cold-accumulation-type central air conditioning system for a villa. A concave reflecting suface collects sunlight reflected back by a solar cell panel through a heat collection tube so as to heat cooling water, thus the temperature of the cooling water is further improved; heated hot water is sent to a user so as to meet the demands of daily life; the energy collected by the solar cell panel is supplied to a double-working-condition refrigerating unit through an energy storage device, and the refrigeration power generated by the refrigerating unit is stored through a ice bucket water cold accumulation technology so as to conveniently supply cold to a room when refrigeration is needed in the day; and under the condition that the solar produced electricity is not sufficient, the double-working-condition refrigerating unit can operate normally depending on the power grid electricity, can utilize the solar produced electricity to refrigerate and accumulate cold in the day, and also can utilize the low-price power grid electricity to accumulate cold at night so as to meet the refrigeration demands in the day. The system is obvious in energy-saving effect and good in economic benefit, can utilize the solar produced electricity and the electricity for a nighttime power grid to refrigerate and accumulate cold, and simultaneously can recover solar energy waste heat.
Description
technical field [0001] The invention relates to the field of central air-conditioning and refrigeration, in particular to a central air-conditioning system of a villa central air-conditioning system of a solar heat and power cogeneration cold storage type. Background technique [0002] Solar photovoltaic power generation technology has been commercially produced decades ago and combined with power storage technology and solar power generation. However, the power generation efficiency of solar panels has always been low, and the power generation efficiency of ordinary panels is mostly below 16%. Improved power generation efficiency has been improved, but due to its high price, there is still a long distance from popularization and application. At present, in the practical application of solar cells on the market, 80% of solar energy is not converted into electrical energy, but converted into thermal energy. When the solar radiation is strong, the photoelectric conversion effi...
