In the production process of winter glass greenhouses, heating machinery and equipment cannot be lacking. Glass greenhouse manufacturers recommend multiple heating methods. What are the heating methods for glass greenhouses?
1. Gas boiler heating
Coal, oil, and natural gas can be used as natural raw materials for gas boilers, and boiling water can be used to heat glass greenhouses. According to the ignition of natural materials, water is heated, and boiling water is heated through the heating pipes and mechanical equipment at the end of the greenhouse. The more concentrated the pipeline layout, the more uniform the temperature inside the greenhouse, and the longer the boiling water heat storage time.
2. Hot blast stove
According to the different materials, the hot air stoves used in Dongfang Glass Greenhouse can be divided into raw coal, gasoline and diesel, and natural gas hot air stoves. Due to the fact that the hot air stove belongs to the instant heating method, without the operation of the heating stove, there is a loss of heat, so the heat of the hot air stove is basically used for greenhouse heating. It can be closed and opened at many times and locations to regulate the temperature inside the greenhouse. The disadvantage is that the temperature inside the glass greenhouse is uneven and fluctuates greatly. Short thermal continuity, can start and stop anywhere, so that the temperature inside the temperature box does not exceed the specified temperature.
3. Electric heating
The heating method of electric heating needs to be based on the conversion of secondary energy. The quality of kinetic energy is high, the cost is high, and the utilization rate of thermal power plants is about 30%. Therefore, although electric heating has a high effect, from the perspective of electricity utilization, the efficiency of electric heating is actually very low. However, in order to maintain the germination rate and germination rate of greenhouse seeds, it is feasible to use electric heating for heating.
4. Heat pump unit heating
A heat pump unit is a mechanical device that collects heat from lower temperature areas and delivers it to higher temperature areas. According to the different heat sources, heat pump units can be divided into air energy heat pumps, ground source heat pumps, etc. Surface water and its underground energy remain stable for a long time. Based on the winter heat, electricity consumption can be greatly reduced, resulting in low daily usage costs.
The above is an introduction to the heating methods of glass greenhouses, hoping to be helpful to you.
