Low-temperature green house

Abstract

The invention relates to the field of design of green houses, and particularly to a low-temperature green house which is established by an internal green house frame and an external green house frame. The outer edges of the external green house frame are coated with a film layer, and the film layer is coated with a sunshade layer. A spray channel is disposed in the intermediate layer between the internal green house frame and the external green house frame, and the inlet of the spray channel is in communication with deep phreatic water. The outer edges of the internal green house frame are coated with a water proof film layer. A heat exchanger is disposed in the intermediate layer between the internal green house frame and the external green house frame, one end of the heat exchanger is connected to the interior of the green house via pipes, and the other end is connected to a blower fan via a fresh air pipe. The low-temperature green house is further provided with an exhaust gas outlet. Illumination devices are disposed in the green house. The low-temperature green house is simple in structure, easy to demount and mount, low in cost and high in utilization rate of material.

Description

technical field [0001] The invention relates to the field of greenhouse design, in particular to a low-temperature greenhouse. Background technique [0002] At present, greenhouses are widely used in the fields of vegetables, flowers, melons and fruits, and animal breeding. Greenhouses with different structures play different roles. The current greenhouses mainly rely on the heat absorption and heat preservation effect of the greenhouse itself. When the temperature is low, it is planted out of season. Temperature-loving crops; or covered with sunshade nets for shading and planting shade-loving crops; or both are constructed at the same time, adjusted according to seasons and weather, to control the temperature in the greenhouse, and to plant in batches all year round. [0003] However, some crops require lower temperatures. For example, some cold-loving crops such as Tianshan snow lotus need to control the temperature below 10 degrees. The current greenhouse structure cannot...

[0003] However, some crops require lower temperatures. For example, some cold-loving crops such as Tianshan snow lotus need to control the temperature below 10 degrees. The current greenhouse structure cannot guarantee the effect of maintaining low temperature in the shed, thus limiting such cold-loving crops. Where the crops are grown

If planted in cold storage, the cost is too high, and it is impossible to maintain sufficient fresh air to ensure the growth of crops
