1.Phytotron Profile：
Artificial climate chamber is in a closed environment for plant and animal production and create a bad environment, it can simulate various weather conditions in nature, in accordance with the requirements of the experimental precision control of temperature, humidity, light, wind direction, wind speed and CO2 gas concentration in the room, etc. a variety of indicators, to reproduce a variety of complex climate. For environmental testing, ecological research, agricultural research (such as crop breeding, tissue culture, cultivation experiment, plant protection, animal breeding), and other fields. Phytotron appears to shorten the period of study, has become an important part of the research, teaching and production.
2.Type：
Phytotron according to the different type of structures can be divided into sunlight, high illuminance, training aircraftthree kinds
Phytotron to be in a different, can be divided into animal and plant artificial climate chamber Artificial climate chamber, biological (microbial) phytotron experiments objects。
Phytotron according to the different experimental purposes, can be divided into Arabidopsis phytotron, controlled ecological life artificial climate chamber, artificial climate chamber and other adversities。
3.Fill light system
Overhead light - sodium or metal halide light sources, these two light sources which can be used alone or in combination with use. Numerous light sources can be mounted in a rack combination, coupled with manual transmission and can be equipped by the controller laboratory manual and automatic control methods to achieve classification regulation.
Light training aircraft-Light training aircraft for the import of plant growth lamps apparel LED light source, training aircraft materials are stainless steel, universal angle steel, aluminum and other materials. Users can ensure maximum light intensity in the light 100-150mm at the bottom (in the standard case), and through control laboratory manual and automatic control methods can achieve grade-control.
CO2 regulation and control system ：
The gas source is bottled liquid CO2, when the concentration is below the set, open the CO2 cylinder valve opening by CO2 pipeline to the fan, fan Hair colleagues start making CO2 evenly distributed throughout the artificial climate chamber through the ceiling to the secondary CO2 concentration stops when reaches the set value; when the concentration is higher than the setting, start the whole heat exchanger into the fresh air to discharge the polluted air of the indoor CO2 concentration reached within a set range, then the new fan stops working。
AIR conditioner for conditioning system：
Artificial climate chamber unit consists of a flexible hermetic scroll compressor refrigeration units imported brand, outlet, and the return air duct composition, the cooling or heating medium through the air into the room thermostat, return air in through the back into the unit, so that repeated cycles of temperature of the indoor complaining standards. Is then controlled by the unified control system, in accordance with the parameters required in air conditioning units after conditioning system has been adjusted, delivered in a uniform indoor climate, which can minimize the volatility of regulation and control to ensure the accuracy of the parameters of indoor air regulation and control, and shape nice.
All of these controls are controlled by Siemens industrial PLC controllers, written according to all the necessary control logic within the controller, and after using the process requires new control can change control procedures to meet the new control requirements, to meet customer demand for a variety of experiments。
Envelope structure：
Usually there will be room tempered glass Envelope structure, color plate cut off and other materials. Climate room floor material having fire waterproof, heat insulation, anti-static characteristics to the construction.
