_ Greenhouse accessories greenhouse accessories wholesale in order to ensure high quality and yield of crops, greenhouse ideal temperature conditions are necessary to maintain the proper temperature, and the temperature distribution again. Greenhouse temperature control is determined by the heating and cooling procedures greenhouse. Some greenhouse accessories greenhouse heat from solar radiation, which is part of the thermal energy through the transparent glass or other covering material [such as plastic film, strengthen the corrugated fiberglass panels, etc.) for which it is in contact with heated objects. The object then warmed longer wave radiating portion of the energy will be absorbed. This part of the heat can not be transmitted through the glass outside the greenhouse, the greenhouse is absorbed by carbon dioxide and water vapor. This is known as the greenhouse effect. Strengthened glass fiber plastic can also produce higher greenhouse effect. The effect of poly (atmosphere) greenhouse effect vinyl film to be worse. But if poly (chlorine) water films on vinyl film can produce the desired greenhouse effect. Absorbed by greenhouse hotbox decision greenhouse air convection and heat distribution condition of the fan in. However, on cloudy days and in winter, the heat generated by solar radiation is not sufficient to maintain the desired indoor temperature, which requires heat energy supplementary part artificially generated. This heat source should be able to produce stable and high heat output, and evenly distributed to all directions. Because in the greenhouse by covering material, thermal and thermal losses through the gap and roof trusses by conduction loss is very fast, it is necessary to continually replenish the heat most. Walls will increase because of the cold wind and heat loss in the parts of a "cold spots."; And the unequal distribution of earnings due to the heat, and some locations will have a "hot spot", low or high temperatures are likely to produce harm to crops. Properly configured heat and heat transfer equipment is the key measures to ensure the ideal indoor temperature.
