Problems solved by technology
The current status of regulating the temperature in the greenhouse: 1. If the greenhouse is maintained at a certain temperature in winter, a boiler must be used. This method is not suitable for controlling the temperature in the greenhouse
In summer, the temperature can only be lowered by ventilation. The ventilation effect of the greenhouse is poor, the ventilation is inconvenient, and the temperature in the greenhouse is difficult to control.
2. Most greenhouses can only adjust the room temperature in the greenhouse but cannot adjust the temperature of the soil, especially in winter, the lowest temperature for the normal water absorption and fertilizer absorption of crop roots cannot be reached.
[0003] Boilers are mostly used for heating in existing greenhouses. Coal-fired boilers will cause environmental pollution, and the cost of oil-fired boilers is too high
There are also some greenhouses that use heat-absorbing pipes installed underground to form a water cycle to obtain heat. This method obtains less heat, and the supply of temperature in the greenhouse is insufficient, so it is difficult to maintain a certain constant temperature.

Abstract
The invention belongs to the technical field of greenhouses and relates to a greenhouse utilizing heat of underwater to achieve heat preservation, in particular to a geothermal greenhouse. The geothermal greenhouse comprises a closed heat-preservation greenhouse body which adopts a combined frame structure. A wall body on one side of the greenhouse is a water curtain radiation wall which comprises a wall foundation and geothermal water curtain radiators, a wall body opposite to the water curtain radiation wall is a fan wall where a plurality of fans are arranged side by side, and the ground of the greenhouse adopts a floor heating system with built-in radiation pipes. The geothermal greenhouse fully utilizes heat of the underwater, is high in heat exchange efficiency, achieves environment-friendly and pollution-free heating, and has excellent environment-friendly effect.
Description
technical field [0001] The invention belongs to the technical field of greenhouses, in particular to a greenhouse using groundwater heat for heat preservation, in particular to a geothermal greenhouse. Background technique [0002] Greenhouse is an essential basic facility for planting and breeding. The current status of regulating the temperature in the greenhouse: 1. If the greenhouse is kept at a certain temperature in winter, a boiler must be used. This method is not suitable for controlling the temperature in the greenhouse. In summer, the temperature can only be lowered by ventilation. The ventilation effect of the greenhouse is poor, the ventilation is inconvenient, and the temperature in the greenhouse is difficult to control. 2. Most greenhouses can only adjust the room temperature in the greenhouse but cannot adjust the temperature of the soil, especially in winter, it is impossible to reach the minimum temperature for the crop roots to absorb water and fertilize...
