Description

Technical Field

[0001] This utility model relates to the field of greenhouse cultivation technology, specifically a crop root heating system. Background Technology

[0002] With societal development, traditional energy sources have increasingly been applied to greenhouse heating. Fossil fuels such as coal have become the primary energy source, leading to the invention of various coal-fired heating devices, such as coal-fired boilers. These boilers generate heat by burning coal, heating water into hot water or steam, which is then piped to radiators in the greenhouse to raise the temperature. This method significantly improves the heating capacity of greenhouses, reducing reliance on natural sunlight to some extent and allowing greenhouses to operate normally in colder regions and seasons. However, coal-fired heating equipment has many drawbacks, such as generating large amounts of pollutants that cause serious environmental pollution. Furthermore, the transportation and storage of coal are cumbersome, requiring frequent manual refueling and resulting in high labor intensity.

[0003] Existing greenhouse crop heating systems are crucial facilities for ensuring the normal growth of greenhouse crops in low-temperature environments. These systems use hot water boilers to heat water, which is then circulated through heat dissipation pipes within the greenhouse by a circulating pump, raising the greenhouse temperature through heat radiation. However, this type of heating system requires a large initial investment, necessitates the laying of pipes, is complex to install, and has high maintenance costs. Utility Model Content
