Temperature and humidity control method of artificial climate box
The artificial climate box, like the light box, can provide a simulated natural environment, such as suitable temperature, humidity, light intensity, etc., to provide a necessary environment for plant growth. In addition, the various parameters of the artificial climate box can be freely set manually, eliminating the uncontrollable annoyance of the natural environment. Temperature and humidity control is the most favorable weapon for the artificial climate chamber system. At the same time of temperature and humidity control, we can use the temperature and humidity self-recording apparatus to measure and keep abreast of the temperature and humidity changes in the artificial climate chamber.
When the temperature is low and the water is heated, the moisture evaporates. The previously cooled or dehumidified condensed moisture in the climate chamber will evaporate and increase the internal humidity. When the temperature is high and the cooling is performed, the humidity of the airflow passing through the refrigerator will be reduced to make the whole box. Humidity of the body decreases; similarly when the humidity is low and the humidity is humid, external cold or hot moisture will change the internal temperature, and high humidity and dehumidification will inevitably lead to a drop in temperature. So the control of temperature and humidity is strongly coupled. In addition, the coupling degree of the temperature and humidity of the box of different specifications is different. In addition, climate chambers require temperature and humidity multi-stage circulation control. The temperature and humidity in the two stages are different. The mathematical model of temperature and humidity control in the climate chamber also indicates that they have large hysteresis characteristics and must achieve rapid rise and transition times. Short-term and over-adjusted purposes, the general control method is difficult to work.
From the above analysis, it can be seen that the control of the temperature and humidity of the climate chamber is coupled with each other. In this way, the control of temperature and humidity is essentially a control problem of a large lagging, strongly coupled system. These characteristics determine that it is difficult to obtain high accuracy in temperature and humidity control. General artificial climate chamber uses separate temperature controllers and humidity controllers to achieve temperature and humidity control, and most of their control methods are PID control methods. The effect of time-varying system control for purely lagging parameters is not ideal, and they are used. It is also inconvenient, and the fuzzy controller is independent of the system's mathematical model, eliminating the need to identify the system, has good robustness and adaptability, and is suitable for control occasions such as model uncertainties and parameter changes. It can just adapt to the temperature and humidity control of the artificial climate box, so the controller of the artificial climate box adopts a fuzzy control method to control the temperature and humidity of the box air flow, and also uses the fuzzy decoupling method to solve the problem of strong temperature and humidity coupling.

1.5 Ton Standing On Type Electric Stacker

Zowell Electric Stacker 1500kg is an industrial device for loading and lifting pallets on a shelf at high level. As an ideal choice to operate in narrow space of warehouse, it can be widely used in petroleum, chemical, pharmaceutical, textile, pigment, coal and other industries, as well as ports, railways, freight yards, warehouses.

Compared with the traditional manual stacking, Zowell full electric stacker maintains great advantages in safety, efficiency and cost. In addition to durability and accuracy both outside and inside, Zowell XE electric stackers are also equipped with mast with clear view, double speed and lateral vertical moving switch, which are valuable when working in limited space.

Detail features

1. Multifunctional handle
The multifunctional handle is imported from Germany. It has integrated control functions including a speed button, horn button, emergency reversing button and lifting button. The handle has an emergency reversing button which can effectively protect the operators from being hurt in accident involving falling items. The handle can realize braking both in vertical and horizontal position. The human-machine design is quite safe and the operation is more comfortable.

2. Strong power
This stacker adopts high efficiency motor which can be precisely controlled and the output power is strong. The turning control can be optionally equipped with EPS. It can help the driver with turning by using electronic control device to produce auxiliary power of relative level and direction according to the torque signal and speed signal. So the operation of the driver can be more convenient and precise and the movement can be more stable and reliable.

3.Superior gradeability
The powerful motor and 5 wheel stacker structure can provide superior stability and gradeability, so that the truck can have sufficient gradeability when it is fully loaded.

4. Buffered pedal
The foldable pedal can save space when the stacker is not in use. It can also effectively protect the drivers from being effected by the bumping and give feedback to the driver with the road condition.

5. Dual balance wheel device
This stacker is equipped with a dual balance wheel so that it can overcome roadblocks easier and the running can be more stable.

6. Emergency power-off switch
The power can be rapidly cut off in emergency to ensure safety.
