Self-temperature-adjusting greenhouse

Abstract

The invention discloses a self-temperature-adjusting greenhouse which comprises a south wall, a north wall, a sunshade, a light transmitting shed and a temperature adjusting water tank, wherein the sunshade and the light transmitting shed tilt toward the south; the temperature adjusting water tank is placed on the ground inside the greenhouse and leans against the north wall; wet curtains are embedded into the north wall; fans are embedded into the south wall; the upper surface of the sunshade is covered by a photovoltaic panel; the photovoltaic panel is connected with the fans through circuits; the south surface of the temperature adjusting water tank is coated by a solar heat-absorption coating; the temperature adjusting water tank is connected with the wet curtains through pipelines. As the greenhouse is supplied with solar energy, and the water temperature is adjusted through the sunshade, an effect of greenhouse temperature adjustment can be achieved under the condition that no additional energy is available, and the self-temperature-adjusting greenhouse is simple in structure, low in cost and large in popularization potential.

Description

technical field [0001] The invention relates to a greenhouse, in particular to a self-regulating temperature greenhouse, which belongs to the technical field of solar energy utilization. Background technique [0002] As a clean, non-polluting renewable energy source, solar energy is considered an important part of the world's energy strategy for its development and utilization. Solar water heaters have been successfully commercialized, and how to use solar energy more effectively has become the content of research by scientists from all over the world. [0003] Greenhouses can transmit light and keep warm, and are widely used to grow plants. In seasons that are not suitable for plant growth, the greenhouse can provide a growth period and increase production, and is mostly used for planting or raising seedlings of temperature-loving vegetables, flowers, forest trees and other plants in low temperature seasons. [0004] The solar greenhouse is one of the important forms of t...

Problems solved by technology

[0005] The current solar greenhouse is mainly used to increase the temperature in the greenhouse during the day in winter. Although the greenhouse has a certain heat preservation effect, the temperature in the greenhouse at night is low, especially in winter, which is not conducive to the production of plants in the greenhouse. In other seasons, due to the temperature of the greenhouse Influence, under the sunlight during the day, it will cause the temperature in the greenhouse to be too high, which is also not conducive to the growth of plants

Therefore, some greenhouses are equipped with heating devices and cooling facilities. These devices not only significantly increase the initial investment of the greenhouse, but also bring higher operating costs. While wasting energy, it also reduces the profit of crop cultivation.
