Active heat accumulating type greenhouse

Abstract

The invention provides an active heat accumulating type greenhouse. The active heat accumulating type greenhouse comprises a greenhouse framework, a heat preservation film covered on the greenhouse framework and an active heat accumulating back wall connected with the greenhouse framework, wherein the active heat accumulating back wall comprises a heat preservation wall, a heat accumulating device and a draught fan, wherein the heat accumulating device and the draught fan are arranged in the active heat accumulating type greenhouse, the heat accumulating device comprises a heat accumulating wall body and heat transmitting pipes arranged in the heat accumulating wall body, one end of each heat transmitting pipe is connected with an air exhaust port of the draught fan, the other end of each heat transmitting pipe is communicated with the active heat accumulating type greenhouse, the air inlet of the draught fan absorbs hot air in the active heat accumulating type greenhouse and continuously conveys the hot air into the heat transmitting pipes through the air exhaust port of the draught fan, heat of the hot air is transmitted to the heat accumulating wall body by the heat transmitting pipes, and therefore the heat accumulation is achieved.

Description

Technical field [0001] The invention relates to the technical field of agricultural planting equipment, in particular to an active heat storage type greenhouse. Background technique [0002] Greenhouse, also known as greenhouse, can transmit light and keep warm, and is a facility used to cultivate plants. In the seasons that are not suitable for plant growth, it can provide growth period and increase yield. It is mostly used for plant cultivation or seedling cultivation of temperature-loving vegetables, flowers, forests and so on in low temperature season. There are many types of greenhouses, which can be divided into many types according to different roof truss materials, lighting materials, shapes and heating conditions, such as glass greenhouses, plastic greenhouses; single-span greenhouses, multi-span greenhouses; single-roof greenhouses, double-roof greenhouses; Heated greenhouse, non-heated greenhouse. The greenhouse structure should be sealed and insulated, but it should...

AI Technical Summary

Problems solved by technology

[0005] However, the above-mentioned prior art has the following problems: the heat transfer medium in the liquid storage tank is used to passively absorb the heat transferred from the light-transmitting layer, and the heat obtained in the limited illumination time is small, resulting in an inconspicuous heat storage effect; in addition, the above-mentioned With heat absorption, heat storage, heat release and heat preservation system, the structure is complex and difficult to construct. For example, the liquid storage tank needs to have high sealing performance and pressure bearing performance, the size of the liquid storage tank is limited, and pipelines need to be buried on the ground in the greenhouse Wait
