Description

Technical Field

[0001] The utility model relates to the technical field of greenhouses, and in particular to a heat-collecting air pipe for a temperature-regulating water wall and a heat-storing temperature-regulating greenhouse. Background Art

[0002] Greenhouses are generally composed of enclosing walls on both sides, a rear wall at the back, a supporting frame and covering materials covering the supporting frame. They are important agricultural facilities in the northern region. The covering materials covering the supporting frame are often made of transparent plastic film, which mainly provides a suitable temperature and humidity environment for crops in the autumn and winter seasons, increases the yield of crops, and enables the northern region to obtain fresh fruits and vegetables in the autumn and winter seasons.

[0003] When the temperature in the greenhouse is low at night or in severe cold weather, heating furnaces or electric heating are often used to increase the temperature inside the greenhouse; when the temperature in the greenhouse is high during the day, in order to prevent crops from wilting and drying up, the greenhouse is often required to be ventilated and cooled. Ventilation and cooling during the day causes the heat collected in the greenhouse to be dissipated, and using heating equipment to heat the greenhouse at night or in severe cold weather consumes a lot of energy.

[0004] Some greenhouses are equipped with gas pipelines on the top to discharge the hot air from the top of the greenhouse out of the greenhouse, providing circulation power for the air circulation inside the greenhouse. As the hot air is discharged, the moisture in the interior of the greenhouse is also discharged, which reduces the humidity of the air and soil in the greenhouse, which is not conducive to the growth of crops.

[0005] In addition, crops in greenhouses also need irrigation in winter. Irrigating crops with cold water may also cause the roots of crops to freeze, which is not conducive to the growth of crops. Some crops in greenhouses are often irrigated with warm water. Heating cold water in winter often requires more energy consumption, and using conventional sunlight to heat cold water takes a long time. Therefore, there is an urgent need for a heat-collecting air pipe for a thermostatic water wall that can assist in regulating the temperature in the greenhouse and has a moisturizing property, and a heat-storage thermostatic greenhouse that can increase the temperature in the greenhouse when the temperature is low to save energy. The warm water in the thermostatic water wall can be used at any time to irrigate seedlings without heating. This is a technical problem that technicians in this field urgently need to solve.
