Each cabin consists of: 1. Each cabin is located two floors, two light fixed, easy disassembly, easy to replace the lamp (LED light panels can be replaced; lower fluorescent lighthouse removable). Upper sodium lamp as the light source to the planting area, planting late in the growing plants; lower planting area to fluorescent light as the light source, planting plants in the early growth stage. The range of light intensity in the case :( normal growth of plants, each plant at the plant leaves Peng) 200 micromoles / m / sec to 2500 micromoles / m / sec (sodium 40000LUX) Cultivation compartment supporting layer height can be easily adjusted. 2, two independent incubator side are flange sealing plate, sealing plates are provided between the material exchange; 3, and after each of the two chambers in the same height to the planting units operating gloves (inner gloves have sealed cover, sealing methods and principles Shellab on similar anaerobic incubator); 4, two cabins front set with a valve threaded hole (the hole is threaded, diameter 2cm); set glass observation hole, the hole is not outside translucent steel door (its color and consistency cabinet, wall polished); 5, due to the condensation of water in each cabin cooling and dehumidifying produce condensate tank back, and then was assigned to the humidifier tank and nutrition through the pump in the tank , the flow path has two valves; 6, front and rear are located at the same height observation window, an observation window for the upper and lower layers; frost glass, and observation window are fitted with a small door, small door to be reflective inner wall stainless steel mirror reflective material; and July, two independent housing may be gas exchange, ie left and right sides, respectively, of the entire apparatus is provided with a vent valve (pore size with the pump according to the required size), between the two by the fan vent and trachea (placed in the test chamber is connected to the uppermost; two independent rear vent with a valve set top box connected to the chamber by placing the uppermost centrifugal fans and vent pipe between the two; 8, two independent cabinet front tees are located with a sealable outlet, three-port can be connected adjustable tube (outside diameter of 2 cm, with a male thread); 9, all incoming and outgoing pipe tee are set aside for the band valve; 10, in the box on the left and right sides by position, respectively, with two-way valve with pores (outer diameter of 2 cm, with a male thread, the specific location see figure); both sides of the 11, two independent incubator flange outer diameter surface portions arranged two 2cm, adjustable head with external thread (specific location see figure) cold-rolled steel shell material, surface electric spray; inner wall mirror stainless steel material imports (SUS304 #); insulation material Polyurethane foam, thickness 50mm; training aircraft and room × 2 2 sets of light training aircraft, each bearing ≤50Kg, position adjustable height; top light for the US GE sodium is 2 × 2; the lower part of the light source for the PHILIPS T5 lamp × 2 ; quantum sensor: 2 sets of wiring 2 meters, removable air conditioning systems use a combination of balanced thermostat humidity (BTHC) method refers to a method for controlling adjustment .BTHC continuous operation in cooling system based on different control points and different control factor automatic control actuator response time, the output response process actuator and actuator and other factors, so that the system to achieve a dynamic equilibrium. The system response time adjustment method using PID mode, that is, the controller transmitted by the sensor Comparison of signal analysis and controller set value, through a series of operations, in certain circumstances under the control of the cycle, adjusting the duty cycle within a cycle way air circulation device: built air-conditioned rooms, circulation air duct and the long axis of the centrifugal fan using energy efficient refrigerators and conditioning systems working indoor air sucked through the air board, and the evaporator heater energy exchanged, inhaled by the fan after mixing, the uniform wind deflector shunt into the studio. The system of nutrient solution, nutrient solution tank placed under each culture tank, through valve, the pump tank of the culture solution periodically or continuously supplying nutrient solution tank cultivation, nutrient solution tank is equipped with dust, the openable lid and set I have read sight gauges; 2, each culture placed high indoor cultivation box 10cm (length and width determined by the size of each work) on each cultivation layer, there is a water inlet and outlet boxes, inlet duct connected to the nutrient solution ; connected to the water mains, ensure nutrient solution can be delivered to the cultivation of the box after a period of time between the outlet of the tank back into the nutrient solution and nutrient solution pool; 3, the bottom surface of the cultivation box with a certain slope, aspect outlet boxes, each cultivation Place the bottom surface of the groove holes for planting small plants cultivation box; 4, nutrient solution delivery frequency and duration can be set; the use of submerged irrigation methods that periodically nutrient solution is delivered to the cultivation tank plant matrix in nutrition liquid immersion period of time (immersion length adjustable), nutrient flow back after the nutrient solution tanks; 5, the condensed water generated in the device to flow back into the condensate tank, then under the action of the pump can be connected to the nutrient solution through the tank or ( and) the humidifier water flows into the nutrient solution tanks or (and) inside the humidifier. Carbon dioxide systems on two separate culture chambers were set sealable CO2 intake pipe valve and seal the intake manifold valve (CO2 intake port located on the back of the incubator, the air outlet located on the front and the specific location see figure) . CO2 control system controls the culture chamber supplement frequency and velocity of CO2.
