Electric Heating Method Of Intelligent Greenhouse
Nov 01, 2017

The purpose of greenhouse ventilation is to eliminate the heat and moisture in greenhouse, adjust the indoor air composition, eliminate harmful gases, and make the environment temperature, humidity and air in greenhouse suitable for plant growth. When the roof wind window is open, the sash should be better than the horizontal tilt, the full opening and the horizontal surface to form 100 angle, you can get good ventilation effect.Intelligent Greenhouse

The ventilation capacity of natural ventilation is related to wind speed, wind direction, ventilation window location, ventilation window area and temperature difference inside and outside greenhouse. When the total area of the ventilation window is 27% of the indoor area, if only the roof ventilation, even if the outdoor wind speed reached 10 km/h, also up to 0 per minute. 75 times ideal ventilation rate; When the roof ventilation window and the side wall ventilation window are fully open, the ventilation rate can reach 0.68 times/min in the case of almost no wind, close to the normal recommended 0.75/min ventilation rate.Intelligent Greenhouse

Hot water heating system by hot water boiler, heating pipe and cooling equipment three basic components, its work process is to use the boiler to heat water, and then by the pump pressure, hot water through the heating pipeline to supply the radiator in the greenhouse, through the radiator to heat, improve the temperature of the greenhouse, cooling hot water back to the boiler reheat repetitive cycle. The hot water heating system is stable and reliable, and it is the most commonly used heating mode in glass greenhouse at present.Intelligent Greenhouse

Hot air Heating system is composed of heat source, air heat exchanger, blower and air supply duct. Its working process is: heat-supply heating air ventilator by heat source, forcing some air in the greenhouse to flow through the air heat exchanger, so as to continuously circulate the greenhouse heating. Hot air heating system can be a heat source of fuel, gas, coal-fired device or electric heater, can also be hot water or steam.Intelligent Greenhouse

The more common method of electric heating is to bury the ground line underground, to improve the geothermal, mainly used in greenhouse nursery. Electricity is the cleanest and most convenient energy, but the electricity is two times the energy, itself is more expensive, so can only be used as a temporary heating measures for short-term use.Intelligent Greenhouse
