Disclosed is an automatic constant-temperature system for a hydroponic nutrient solution with low energy consumption. The system is characterized in that a solar panel, a cool water tank, a backwater tank, a nutrient-solution heat-preservation box and a control box which are installed around a solar energy heater; a heating-medium spiral pipe is installed in the nutrient-solution heat-preservation box, and the nutrient-solution heat-preservation box is provided with a hydroponic pipe going to a hydroponic tank, one end of the heating-medium spiral pipe is provided with a water conveying pipe communicated with the backwater tank, and the other end of the heating-medium spiral pipe is provided with a three-way constant-temperature water-mixing valve and a water conveying pipe communicated with the solar energy heater and the cool water tank; the solar energy heater is communicated with the cool water tank through a conveying pipe, the solar energy heater is communicated with the backwater tank through a conveying pipe, and a backwater booster pump is assembled between the solar energy heater and the backwater tank; the solar panel is communicated with the control box through a wire. Through the adoption of the automatic constant-temperature system for the hydroponic nutrient solution with the low energy consumption, the problems are solved that the circulating hydroponic nutrient solution is directly heated, the energy consumption is high, and the nutrient elements are destroyed, and the system is widely suitable for the usage of hydroponic nutrient solutions in greenhouses and other places.
Description
technical field [0001] The invention relates to the field of planting equipment, in particular to a constant temperature circulation system for hydroponic nutrient solution in greenhouses. Background technique [0002] The hydroponic nutrient solutions currently used in greenhouses are all directly heated and circulated. The disadvantages are high energy consumption, and unstable temperature is easy to destroy nutrient elements. Contents of the invention [0003] In order to solve the problems of high energy consumption and destruction of nutrient elements by directly heating and circulating hydroponic nutrient solution in greenhouses, the present invention designs a constant-temperature hydroponic nutrient solution system heated by an indirect medium. [0004] The technical solution of the present invention is an automatic constant temperature system for hydroponic nutrient solution with low energy consumption. The special feature is that solar panels, cold water tanks, r...
