Greenhouse (greenhouse), also known as greenhouse. A facility that can transmit light, keep heat (or heat), and cultivate plants. In the seasons that are not suitable for plant growth, it can provide greenhouse 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.
The types of greenhouses include planting greenhouses, breeding greenhouses, exhibition greenhouses, experimental greenhouses, catering greenhouses, entertainment greenhouses, etc.; greenhouse system design includes heating system, heat preservation system, cooling system, ventilation system, control system, irrigation system, etc.; greenhouses are just Simple plastic film and skeletal structure have few internal facilities and are not as demanding as greenhouses. Therefore, strictly speaking, the equipment requirements of greenhouses are higher than that of greenhouses, and more advanced instruments may be used to strictly control the temperature.
But broadly speaking, the greenhouse is a kind of greenhouse. Its purpose is also to maintain a certain temperature.
Heating and energy consumption are the main obstacles to the operation of greenhouses in winter. Improving the thermal insulation performance of the greenhouse and reducing the energy consumption are the most direct means to improve the efficiency of greenhouse production. The thermal insulation ratio of the greenhouse is a basic index to measure the thermal insulation performance of the greenhouse. The greenhouse thermal insulation ratio refers to the ratio of the area covered by the light-transmitting material of the greenhouse with lower thermal resistance to the area covered by the greenhouse envelope with the larger thermal resistance on the same ground. The greater the heat preservation ratio, the better the heat preservation performance of the greenhouse.
The thermal insulation performance of the greenhouse is very good. Heating energy consumption is the main obstacle to the operation of the greenhouse in winter. Improving the thermal insulation performance of the greenhouse and reducing the energy consumption are the best ways to improve the efficiency of greenhouse production.
