System sostarivaniya greenhouses automatic

Innovative sostarivaniya greenhouses for overheating protection of air and reduce heat loss inside the greenhouse.

 

 

System sostarivaniya is intended to prevent overheating of the air inside the greenhouse during periods with excess solar radiation by shading, and to reduce heat loss in the greenhouse during the cold periods of the year, creating a more uniform and favorable for the plants of the temperature field. Provides savings of thermal energy up to 40% by reducing heat transfer through the roof of the greenhouse.

Description:

System sostarivaniya is an important component of modern greenhouses, influencing the microclimate, and ensure its efficiency. Using sostarivaniya you can adjust the lighting, temperature, humidity, and also considerably to save heat.

System sostarivaniya is intended to prevent overheating of the air inside the greenhouse during periods with excess solar radiation by shading, and to reduce heat loss in the greenhouse during the cold periods of the year, creating a more uniform and favorable for the plants of the temperature field. Provides savings of thermal energy up to 40% by reducing heat transfer through the roof of the greenhouse.

The material of the screen (curtains) often is a polyester fabric with interwoven strips of aluminum foil. The material is very durable, allows no damage to repeatedly pull and push the screen at the same shifted screen has a minimum size, giving the minimum of shading.

  

The screens are horizontal (upper) and vertical (lateral). Horizontal zashtorivayte is located at the top of the greenhouse, under the roof, is installed in all branches of greenhouses in each span, between sections, between the upper chord, allowing a complete cut-off of the ridge of the greenhouse from the rest of the volume.

The screen is driven by a mechanism sostarivaniya, and it can be opened and closed, stopping at any end or intermediate position, depending on external weather conditions and the needs of crops. The mechanism design sostarivaniya moves all sections of the screen simultaneously or partially in all the spans of the Department greenhouses.

 


Types of screens (curtains):

– energy-saving. Screen gives maximum heat retention with minimal loss of light. Used in greenhouses located in cold climates. Among the advantages of energy-saving screen, saving financial costs and reducing the harmful effects of heating on the environment;

– shade. Aluminum strips to screen fabric provide the desired level of reflection of sunlight. When this hot air passes from below through the fabric. Used in a hot climate, to enhance the effect, use a combination of multiple screens;

combined energy saving and shading. In bright sunlight the screen reflects excess heat. When cold the screen keeps the heat, reduces the risk of moisture condensation on the plants and energy saving;

– obscure. Used in the cultivation of plantsrequiring additional periods of rest. Two-layer structure of the screen can give more than 99.9% blackout, there are the kinds with aluminum or white top layer to reflect sunlight and a white inner layer;

– retro-reflective. Is used to keep artificial light inside the greenhouse space, which increases the efficiency of assimilation lighting and protects the environment from stray light. Special fire-resistant fabric structure allows moisture and heat to pass, but detains the light.

 

The advantages of using curtain screen:

– expanded inside greenhouses, the screen reduces heat loss by 43-75% (depending on the type of tissue) and as a result achieved savings of thermal energy by more than 20%,

enables the shading in the range from 15% to 85% and even the creation of “artificial night”

– curtain screen gives you the ability to control humidity in the volume of the greenhouse. At night curtains provide heat retention, thereby preventing condensation on the plants

– fully automatic operation. Screen opens (closes) as needed from the switch on the control Cabinet or in the automatic mode of the control system of the microclimate of the greenhouse. Most often used centralized management system sostarivaniya from the unified system of automatic control of the greenhouse. To maintain the required light levels, temperature and humidity, conserve heat, the computer, based on a given strategy and external factors, calculates the required position of the screens separately in each compartment and gives commands to respective gearmotors.
