specific Embodiment approach

[0027] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] like figure 1 As shown, a comprehensive energy utilization system in a greenhouse of the present invention includes a soil cooling device 5, which is located under the land of the greenhouse 10; a first water pump 4; a heat storage device 2, the heat storage device Including water heat storage system and soil heat storage system; solar heat collection device 1, the solar heat collection device is a solar heat utilization technology that uses functional fluid to improve solar heat collection efficiency, and has technical characteristics such as high thermal efficiency and high water temperature. The heat exchange pipe 3 of the heat storage device; the automatic liquid replenishment water tank 6; The heat energy is released to the soil heat exchange device 5 through the first circuit; as shown in t...

Embodiment 2

[0030] Example two as figure 2 Shown is the system diagram of Embodiment 2 of the present invention. The difference from Embodiment 1 is that the system also includes an air heat exchanger 8 and the pipelines connected thereto in the greenhouse 10. The air heat exchanger The device 8 includes a fan, which exchanges heat by circulating the air in the greenhouse and the water in the heat exchange pipeline 3 of the heat storage device 2 . In this embodiment, the heat storage device 2 can transmit heat energy to the air in the greenhouse through the air heat exchanger 8. Specifically, the regulating valve four 14 and the regulating valve six 16 are opened, and the other valves are closed. The water in the heat pipe 3 becomes water with thermal energy after being heat-exchanged by the heat-storage medium, and enters the air heat exchanger 8 after being pressurized by the first water pump 4. The temperature of the air rises, and the cooled water enters the heat exchange pipe 3 to...

Embodiment 3

[0032] Embodiment three as image 3As shown, the difference between the third embodiment and the second embodiment is that after passing through the confluence point A after the air heat exchanger 8 and the soil cooling device 5, there is a pipe connected between the regulating valve 2 and the heat storage device Road bypass regulating valve 17. In this way, open the regulating valve six 16, the bypass regulating valve 17 and the regulating valve three 13, and close the other regulating valves, so that the direct heat exchange between the air heat exchanger 8 and the heat storage medium in the heat storage device 2 can be realized, which is better The efficiency of heat exchange is improved. That is, the heat storage device 2 is connected to form a fourth circuit through the first water pump or / and the second water pump and the air heat exchanger 8 .

[0033] Similarly, the soil cooling device 5 can also conduct direct heat exchange from the heat storage device 2 directly th...

Description

technical field [0001] The invention relates to a greenhouse energy comprehensive utilization system. Background technique [0002] As we all know, room temperature and soil temperature not only have a great impact on the growth, development, and reproduction of plants, but also have an impact on the conditions of water, air, and nutrients in the soil. Therefore, temperature conditions are the basic conditions that should be paid attention to in greenhouse production. [0003] A greenhouse is a kind of animal husbandry and gardening facility that humans control and simulate the natural climate in a building site for plant cultivation, mainly to provide suitable climatic conditions for plant growth, development, and reproduction. At present, my country has promoted solar greenhouses of more than 40×104 ha (hectares), and the greenhouse cultivation area in the suburbs of some large and medium-sized cities has increased rapidly, exceeding more than 10% of the local vegetable f...
