Greenhouse energy-saving auxiliary temperature control system

Abstract

The invention discloses a greenhouse energy-saving auxiliary temperature control system, which comprises a water supply well, a main water supply pipe, heat exchange pipes, a main water return pipe and a water return well and is characterized in that the main water supply pipe and the main water return pipe are in parallel arrangement, the heat exchange pipes are vertically and uniformly connected with the main water supply pipe and the main water return pipe, the two ends of each heat exchange pipe are respectively connected with the main water return pipe and the main water supply pipe, the main water supply pipe is connected to a submersible pump positioned in the water supply well, and the main water return pipe is connected to the water return well. When the greenhouse energy-saving auxiliary temperature control system is adopted, the temperature in a greenhouse can be more efficiently and accurately regulated, the system utilizes the temperature differences between the underground water and the natural temperature for raising or lowering the temperature in the greenhouse, the great nonregenerative resource waste can be prevented, and the effect of protecting the environment can also be reached, so the temperature regulating cost of the greenhouse is further reduced, good economic benefits can be generated, in addition, the structure is simple, and the popularization and the use are convenient.

Description

technical field [0001] The invention relates to a system for auxiliary temperature rise and fall in a greenhouse, in particular to a greenhouse energy-saving auxiliary temperature control system. Background technique [0002] With the development of the economy and society, people's growing living needs, the greenhouse used to provide various off-season plants or animals has become an infrastructure that needs to be developed urgently. Due to the relatively large natural temperature changes in spring, summer, autumn and winter, using various methods to keep the temperature in the greenhouse constant has become a new technical field, and it is constantly developing. [0003] The current status of temperature regulation in greenhouses: [0004] 1. If the greenhouse in winter (especially in the northern region) maintains a certain temperature, a boiler must be used to heat it. This method consumes a lot of energy; in summer, the temperature can only be lowered by ventilation o...

AI Technical Summary

Problems solved by technology

[0004] 1. If the greenhouse in winter (especially in the northern region) maintains a certain temperature, a boiler must be used to heat it. This method consumes a lot of energy; in summer, the temperature can only be lowered by ventilation or water curtain wall, but the effect is not good. very ideal

[0005] 2. Most greenhouses can only adjust the temperature in the greenhouse but not the soil temperature, especially in winter, the lowest temperature (12 degrees) that the crop root system can absorb water and fertilizer normally cannot be reached

[0006] 3. Boilers are mostly used for heating in existing greenhouses. Both coal-fired boilers and oil-fired boilers will not only cause environmental pollution, but also cost a lot
