Prefab Greenhouse with Sandwich Panel & Steel Structure Lida Group

GREEN HOUSE PRODUCTS

Lida greenhouse is a kind of place which can change plant growth environment, create the best conditions for plant growth, and avoid the influence of seasonal changes and bad weather. It uses daylighting covering materials as whole or part of the structural materials, and can cultivate plants in winter or other seasons that are not suitable for open-field plant growth. The aim of greenhouse production is to regulate the production period, promote growth and development, control pests and diseases, and improve quality and yield.
The design concept of Lida greenhouse is "adhere to scientific and practical principles; adhere to the principles of improving the utilization rate of land resources, energy saving, water saving and high efficiency; adhere to the principle of advanced, reliable and appropriate selection of greenhouse structural materials and equipment; adhere to the principle of world leading".

Lida greenhouse mainly includes greenhouse foundation, main structure of greenhouse, covering materials, ventilation system, internal shading system, fan damp curtain cooling system, distribution electric control system, etc. The greenhouse designed by our company adopts hot-dip galvanized light steel structure, which has strong wind and snow resistance and long service life. We are devoted ourselves to building excellent greenhouse projects for our customers.

Greenhouse is suitable for planting flowers, vegetables, melons, fruit trees and so on. There are many kinds of greenhouse. According to different materials, greenhouse can be divided into the following four types:
Film greenhouse, glass greenhouse,solar panel greenhouse,solar photovoltaic greenhouse

1.1） Single-layer film greenhouse

1.2）Double-layer film greenhouse

Glass Greenhouse

Greenhouse structure

Greenhouse characteristics

◆ Solves the contradiction between heat preservation and light transmission in greenhouse. Good heat preservation in winter.  

◆  The unique glass sealing structure completely solves the problem of water leakage.

◆  Glass greenhouse has the advantages of beautiful appearance, good light transmission, good display effect and long service life.

◆  It has the function of preventing fogdrop, setting dew water collecting groove under the open gutter, which can collect the dew water and guide it to the end of the greenhouse, so as to reduce the occurrence of diseases and insect pests.

◆ This type of greenhouse can realize full automatic control. The corollary equipment can choose heating system (hot fan heating or water heating), sunshade curtain system, mist or water curtain cooling system, CO2 supplementary system, light supplement system and spraying, drip irrigation and fertilization system, computer integrated control system, top spraying system, etc.

Greenhouse structure

Greenhouse characteristics

◆ The greenhouse has the characteristics of multi-roof in one span, small roof, multi-gutter and large span, and the interior can be flexibly partitioned.

◆  Good lighting performance and Indoor lighting uniformity

◆  It has strong drainage capacity and can be used for large area multi-span.

◆  Aluminum alloy profiles or special link seals, link seals, beautiful appearance

◆  It has the function of preventing fogdrop, setting dew water collecting groove under the open gutter, which can collect the dew water and guide it to the end of the greenhouse, so as to reduce the occurrence of diseases and insect pests.

◆  The effect of heat preservation and energy saving is better than that of single-layer glass, which can save a lot of fuel in winter, but its transmittance is worse than that of single-layer glass.

◆The interior is spacious and bright, the operation space is large, and the utilization rate of greenhouse is high.

Arched Roof sunlight Board Greenhouse

Greenhouse structure

Design Load: Wind Load 0.30 kN/㎡

Snow load: 0.40 kN/㎡

Span: 6.4m/8.0m/9.6m

Eaves height: 2.5m-8.0m

Column Spacing: 4.0m

Greenhouse characteristics

◆ Curved roof is more conducive to the decline of rainwater and snow, reduce wind resistance, improve the load resistance of greenhouse, reduce dew drop, and reduce the incidence of pathogens caused by excessive humidity.

◆ The opening of skylight at the top of greenhouse conforms to the flow direction of hot air, is conducive to the flow of air and the loss of heat, and is conducive to cooling and dehumidification in summer.

◆ Gutter with large flow

◆ Large span, large column spacing, tall type can be widely used as ecological restaurants, leisure and sightseeing greenhouses and large flower markets.

◆ The top cover can be double-deck hollow board and double-deck gutter, which can effectively prevent dew and reduce energy consumption for heating in winter.

Solar photovoltaic greenhouse

◆ Solar photovoltaic greenhouse is a new kind of greenhouse. It is a greenhouse that lays solar photovoltaic power generation device on the sunny surface partially or totally. It not only has the power generation capacity, but also can provide suitable growth environment for some crops or edible fungi.

◆ Photovoltaic greenhouse project is the product of the organic combination of sightseeing agriculture and facility horticulture. It is an innovative agricultural industry that integrates photovoltaic power generation, agricultural sightseeing, agricultural crops, agricultural technology, landscape and cultural development.
At the same time, Lida greenhouse can supply external shading system, internal shading system, cooling system, heating system and supporting components according to the needs of customers.

External sun-shading system

◆ The main function of this system is to shade the sun and cool down in summer, so that the sunlight diffuses into the greenhouse, to ensure that crops are not burned by strong light. As a result of blocking the entry of a large number of light, the accumulation of heat in the greenhouse is effectively reduced.
◆ Anti-ultraviolet, anti-hail, reduce the damage to the top of greenhouse
◆ According to the different crops planted, the curtain with different shading rate is selected to meet the sunshine demand of different crops.
◆ Shading and cooling: Closing curtain can effectively reflect part of the sunlight in summer, which can make the temperature of greenhouse drop by 4-6 C.hella gastropub glossier man bun biodiesel offal shaman cleanse

Inner sun-shading system

◆ Fog and Drop Prevention: When the inner shading system is closed, two separate spaces are formed at top and bottom of the greenhouse, which can effectively prevent the formation of fog and dew in the greenhouse.
◆ Energy-saving and heat preservation: In winter and at night, it can effectively prevent heat spillover from greenhouse through radiation or heat exchange, so as to reduce energy consumption and operation cost of greenhouse.
◆ Water conservation: can reduce the evaporation of indoor crops and soil moisture, effectively maintain air humidity, reduce irrigation water
◆ Composite thermal insulation wall, internal wall thermal insulation and external wall heating, easy to form a good microclimate in the shed
◆ Using thermal insulation quilt, straw curtain thermal insulation, electric curtain rolling machine in the winter

Cooling System

◆ Cooling system is based on the principle that moisture and heat in air are transformed into latent heat when water evaporates. Wet curtain is installed on one side wall or side wall of closed greenhouse, and fan is installed on the other side wall or side wall. When fan exhausts, negative pressure is generated in the room, which forces the unsaturated outdoor air flow to pass through the porous wet surface of wet curtain, a large amount of humid heat in the air is transformed into latent heat, thus realizing the cooling of air.

Heating System

◆ The greenhouse uses hot water circulating heating system. Hot water heating uses hot water circulating at 60 - 85 C to exchange heat with air. The main equipment is heat source (geothermal well or boiler) and radiator in greenhouse.
◆ Greenhouse mainly uses low temperature hot water heating, the temperature of heat carrier water is not high, easy to operate, suitable for greenhouse heating_radiator layout has a great impact on the greenhouse temperature uniformity, design must be combined with the greenhouse air flow situation to consider carefully layout.
◆ Boiler heater heating, air conditioning heating and other modes can be selected according to the need.
