2. Material structure

2.1 Case StudyArtificial Environment Change Simulation Room on the 5th Floor of National Heavy Industry University, Fujian Agriculture and Forestry UniversityConstruct 8 rooms with external dimensions (length * width * height): ≥ (2600 * 3500 * 2700) mm; Internal dimensions: ≥ (2450 * 3100 * 2150) mm

2.2 Equipped with flame resistant purification color steel plate airtight door, (W90 * H200cm) ± 2cm, with glass window, (W45cm * H45cm) ± 1cm, with regression device attached;

2.3. PVC flooring: thickness ≥ 1.6mm, wear-resistant layer thickness ≥ 0.18mm;

2.4. The artificial climate chamber adopts an embedded air treatment sandwich structure design, with a 75mm thick double-sided color steel 0.5mm polyurethane foam white color steel insulation board as the outer cover, with a density of 42 ± 2Kg/m ³ and a fire rating of B1. The indoor ceiling is 50mm thick polyurethane foam white color steel insulation board, and the ground is equipped with 50mm polyurethane white color steel insulation board. The air outlet is made of 1.5mm sprayed steel plate orifice plates on both sides, and efficient refrigeration and energy regulation systems are used. The indoor air is sucked in through the indoor top suction system, and after energy exchange with the evaporator heater, the fan sucks in and mixes it evenly. It is then diverted from the orifice plate into the working room, reducing the air velocity at the outlet, improving the uniformity of indoor temperature, and the air outlet is quiet. The board is treated with air tightness, and both the inside and outside are treated with anti-corrosion and rust prevention. The door frame is made of specialized purified aluminum, and at the corners of the interior and the connection between the top plate and the wall panel, a specialized purified arc aluminum rounded transition structure is used, with no sanitary dead corners.

3. Technical requirements:

3.1 Temperature control range: 0 ℃~50 ℃;

3.2 Adjustable range of temperature cruise tracking alarm: ± 1.0 ℃~10 ℃;

3.3 Temperature fluctuation: ≤± 1.0 ℃ (three-dimensional air supply mode)

3.4 Temperature uniformity: ≤± 1.0 ℃;

3.5 Humidity control range: 50% RH~95% RH;

3.6 Humidity fluctuation: ≤± 2% RH~5% RH (energy consumption); ≤± 5% RH~8% RH (energy-saving);

3.7 Cultivation rack:

One room is equipped with 6 cultivation racks: using L-shaped edge sealed European standard aluminum profiles as the main material for the overall frame, column specifications: 40 × 40 * 2mm, surface electrophoretic treatment, with a service life of over 20 years; The layer board is adjustable, with 3 practical layers and a layer height of ≥ 60cm. Technical parameters: 6 sets of cultivation racks. Size (length × width × height): ≥ (1200 × 600 × 2000) mm. LED plant specific growth light sources are equipped under each layer of storage board, with long service life, energy saving, and good light uniformity. The storage board is equipped with mirror stainless steel, which is corrosion-resistant. The height adjustment of each storage board is carried out by the four corner slider connectors for tightness adjustment. The front of the storage board is equipped with a shading system, which can effectively prevent the escape of light and cause glare and other injuries to the experimenters. Each cultivation rack is equipped with an independent switch. When the user cannot use it for as long, any one of the cultivation racks can be turned off at will, and the other cultivation racks can be used normally. Each layer of storage board is equipped with main and auxiliary light dimmers on the right side.

3.8 Air filter: fresh air control 0-200m3; filters dust particles with a particle size of ≥ 3 μ m; It can be configured with single-layer activated carbon, similar double-layer activated carbon, and a combination of activated carbon and HEPA filters.

3.11 Power supply: AC 380V50Hz ± 10%, three-phase five wire system;

3.12 The circulation system adopts a three-dimensional air supply circulation system to ensure that there are no temperature and humidity blind spots indoors; Requirements for fan and fan case: The fan requires UL certification, and the fan case is an independent individual that can be disassembled at any time. The disassembly time is ≤ 5 seconds, and it must be PP injection molded as a whole, which can effectively prevent corrosion, leakage, and reduce noise

4. Light source:

4. Light source:

4.1 Full spectrum: 380-800nm

4.2 Light intensity: 50000LX

4.4 Adjustment method: The light intensity can be continuously adjusted from 0-100%, with terminal control

4.5 With sterilization function, press one button to sterilize at any time.

5. Monitoring system:

5.1 Microcomputer: The 10 inch color LCD touch screen (embedded) serves as the human-machine interface, and all parameter displays and settings can be performed on the touch screen. Cooperate with the Max232 interface to connect the controller, equipped with a humidification/dehumidification control system (high-sensitivity humidity sensor and one set of controller/room), and a temperature control system (high-sensitivity temperature sensor and one set of controller/room);

5.2 The tissue culture room adopts an intelligent control system, which can set the time period, temperature, humidity, light, etc. for more than 20 hours. It has the function of setting parameters and recording data, and can also manually control the on or off of indoor light; The manual functions of the control system include: main power supply, operation, cooling, lighting, sterilization, ventilation, and lighting.

5.3 Adopt PID intelligent control mode to control the operation of equipment, achieve automatic detection and control of various parameters in the climate chamber, and enable unmanned operation of the climate chamber. All are automatic control operating systems, and the computer records the entire process in real-time online; It has data storage, memory, and online query functions, and can continue its original working state in case of temporary power outage, shutdown, or restart, thus ensuring that the equipment runs normally according to the program; The automatic protection function of over temperature alarm can prevent damage to the test and equipment due to overheating or overcooling; The electronic control device is equipped with overcurrent protection, short circuit protection, leakage protection, phase loss protection, and parameter abnormality alarm.

5.4 With password lock screen function (three-level password management), unauthorized personnel cannot enter the operation interface to prevent accidental operation.

5.5 Humidity control technology: By using indoor humidity sensors, the ultrasonic humidification system and dehumidifier dehumidification system are activated and adjusted to comprehensively regulate temperature and humidity. The temperature and humidity are mixed evenly inside the control box before entering the room through the air outlet.
