Precautions for the construction of solar panel greenhouse: for the natural ventilation of greenhouse, attention should be paid to: the density difference of surface and interior exchange gases changed from the temperature difference between the outside and interior of the room, which drives the surface and interior exchange of the atmosphere;
The outdoor natural wind becomes the pressure in the greenhouse, driving the rolling of the atmosphere The site selection of the greenhouse is very important. If the local ventilation premise of the greenhouse is good, the air flow in and out of the greenhouse can be exchanged simply, which plays an active role in the ventilation and cooling of the greenhouse.
Structural mode, windowing structure and windowing area of greenhouse: the greenhouse has stable structure, elegant and generous mode, smooth vision, excellent thermal insulation function, moderate light transmittance, rainy trough, large span, lattice frame structure and large drainage;
The greenhouse framework adopts rectangular tube, square tube and other profiles to weld greenhouse beams, columns, purlins and trusses PC board (carbonic acid polyester board) is often used to enclose the top and place, and the space in the greenhouse can be freely split and allocated, the water curtain of the cooling system is hung in the greenhouse.
When the indoor temperature is high, it will be filled with water through the water pump and gradually flow down through the curtain, which plays the role of indoor cooling. The fan diffused in the shed can also adjust the temperature at any time.
Sunshade system at the top of the greenhouse: it is divided into external sunshade, internal sunshade and internal thermal insulation system, all of which are controlled by computer. The weather station system outside the shed may wish to monitor the wind direction and temperature at any time.
The configuration of greenhouse shading system is conducive to reduce the accumulation of heat in the greenhouse. The comprehensive temperature of crops under the sunshade is actually lower than that under the direct mapping of open sun.
The cooling effect of external shading is better than that of internal shading. If the vegetation has special conditions or the greenhouse structure does not agree, the external shading system is usually configured.
Similarly, the different structural design of the external shading system has significantly different cooling effect on the greenhouse. Of course, the external shading system of the greenhouse is the weakest hub in the whole greenhouse, while South China is regarded as a high incidence area of high-temperature storms and typhoons, and the structural strength of the shading system is guaranteed in priority.
