Embodiment Construction

[0014] The active solar greenhouse heat collection-heat storage system of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] see figure 1 with figure 2 , the solar air collector 1 faces south and is placed side by side on one side (east or west) of the greenhouse 2; the underground parallel buried pipes are divided into deep and shallow rows (3 and 4), and are connected in parallel under the greenhouse Greenhouse soil; the two ends of the parallel buried pipes 3 and 4 communicate with two longitudinal buried pipes 5 and 6 of the same depth respectively; The outlet of the heater 1 is connected, and the ends of the longitudinal pipes 5 and 6 are connected with the ground blower 8 through a three-way valve 7 . The longitudinal pipe diagonally opposite to the ground fan 8 bends up to the ground, and is a freely openable and closed end 9; during the daytime, the freely openable and closed end 9 is closed, and the fan 8 d...

Abstract

The invention relates to an agricultural greenhouse utilizing solar energy, in particular to a greenhouse heating system integrating active solar air heat collection and soil heat storage. The system consists of a solar air heat collector, a fan, an underground buried pipe and soil, wherein the solar air heat collector is fixed outside of the greenhouse and is communicated with the underground buried pipe; and the underground buried pipe is arranged in the soil under the greenhouse, and provided with two ports extending out of the ground, and one end of the underground buried pipe is connected with the fan while the other end is freely opened and closed. Compared with the prior art, the active solar greenhouse heat collecting and heat storing system has the advantages of environmental protection, energy conservation, high heat efficiency and so on.

Description

technical field [0001] The invention relates to an agricultural greenhouse utilizing solar energy, in particular to a greenhouse heating system integrating active solar air heat collection and soil heat storage. Background technique [0002] The promotion and application of solar greenhouses is an important symbol of modern agriculture. It gets rid of the constraints of traditional agriculture by natural climate conditions, greatly increases the output per unit area, and also ensures a balanced supply of vegetables and fruits throughout the year. However, in winter and at the turn of autumn and winter and winter and spring in most parts of our country, the climate is cold and the temperature difference between day and night is large. In order to meet the requirements of crop growth, in addition to relying on solar radiation during the day, solar greenhouses must also be artificially heated at night, such as flue heating, hot stove heating, etc. These traditional heating met...
