Production description

Glass greenhouse heating

Agriculture Multi-span Greenhouse in northern my country need to be heated in winter, otherwise they cannot be produced in winter. The length of the greenhouse heating time is different. The heating time in Northeast China takes about 5 to 6 months, and in North China it takes 3 to 5 months. Planting flowers or raising seedlings in the south also requires heating or temporary supplementary heating.

1. Hot water heating The hot water heating system consists of three basic parts: a hot water boiler, a heating pipe and a heat dissipation device. Its working process is to use the boiler to heat the water, and then pressurized by the water pump, and the hot water passes through the heating pipe. Supply the radiator in the greenhouse, and use the radiator to increase the temperature of the greenhouse. The cooled hot water returns to the boiler to reheat and repeat the cycle. The hot water heating system operates stably and reliably, and is the most commonly used heating method for glass greenhouses.

2. Hot air heating: The hot air heating system consists of a heat source, an air heat exchanger, a fan and an air supply duct. The working process is as follows: the heat provided by the heat source heats the air ventilator, and the fan is used to force part of the air in the greenhouse to flow through the air heat exchanger, so as to continuously circulate and heat the greenhouse. The heat source of the hot air heating system can be oil, gas, coal-burning device or electric heater, or it can be hot water or steam. Different heat sources have different installation forms of hot air heating equipment. The air heat exchanger of the steam, electric heating or hot water heating system is installed in the greenhouse and cooperates with the fan to directly provide hot air. Oil and gas heating devices are installed in the greenhouse, and the flue gas after combustion is discharged into the greenhouse. Coal-fired hot blast stoves are generally large in size and dirty in use, and are generally installed outside the greenhouse. In order to make the hot air evenly distributed in the greenhouse, a ventilator sends the hot air into the ventilation duct.

3. Electric heating 　The more common electric heating method is to bury the geothermal wire in the ground to increase the ground temperature, and it is mainly used in the greenhouse to raise seedlings. Electricity is the cleanest and most convenient energy source, but electric energy is a secondary energy source, which is relatively expensive, so it can only be used as a temporary heating measure for a short period of time.
