What are the heating methods in the greenhouse?

Fire heating is a traditional heating method with a long history and the most common use. You can use a fixed stove or a temporary stove for heating. Fire heating was mainly used in greenhouses, and later with the development of plastic greenhouses, it was also applied to greenhouse production in early spring.

2. Hot water heating

Heat with heating tubes and fins. The use of hot water heating is not very common in China, only used in large glass greenhouses and contiguous greenhouses. The advantages are: it is beneficial to the heating of large-area greenhouse groups; When heating, the indoor temperature can be kept uniform, which is convenient to promote the rise of ground temperature; The residual heat lasts for a long time, and there is still a period of heat preservation after the heat is stopped; No harmful gas and smoke.

3. Steam heating

It is rarely used in China, and its heating method has the same advantages and disadvantages as hot water heating, except that hot water is changed into hot gas, which is also convenient for soil disinfection. Waste heat and waste gas from power plants can be combined with agriculture.

Precautions for greenhouse heating:

1, heating energy consumption in winter is the main obstacle to greenhouse operation. Improving the thermal insulation performance of greenhouse and reducing energy consumption are the most direct means to improve the production efficiency of greenhouse. The heat preservation rate of greenhouse is a basic index to measure the heat preservation performance of greenhouse.

2. The heat preservation performance of the greenhouse is very good, and the heating energy consumption is the main obstacle to the operation of the greenhouse in winter. Improving the thermal insulation performance of greenhouse and reducing energy consumption is the best way to improve the production efficiency of greenhouse.
