Description

Technical field

The technical solution relates to a phytotron chamber to ensure a homogeneous environment, in particular heat and humidity parameters.

Background Art

Within the existing ytototron chambers, the distribution of temperature-treated air is done in the form of wall exchangers without the possibility of regulating the flow velocity, the cooling system is provided by a separate cooling unit located under the ceiling. The wall-outlet system is not operationally capable of providing a homogeneous distribution of defined temperature and humidity within the large-scale flue gas chamber. The different air velocity at different locations in the chamber causes a different mixing ratio of the cooler supply air and the warmer air in the chamber (which is heated by the temperature gains mainly from the light). There are then significantly different temperatures in the various compartments, although the average temperature in the box remains within ± 1 ° C. Different air velocity at different locations of the chamber has the same impact on moisture. The humidity of the various compartments varies considerably.

Known systems are therefore complemented by an additional fan for air mixing in the room. This solution can only partially eliminate the above problems. In addition, additional fans and vapors eliminate the possibility of full use of the phytotron chamber.

The essence of the technical solution

The drawbacks of the known thyrotron chambers are largely eliminated by the phytotron chamber according to the invention, consisting of a heat-insulating panel, inside which the venting systems of the chamber space are housed. The essence of the technical solution is that an inner structure is formed on at least one side of the heat-insulating panel, forming an air gap between the heat-insulating panel and said inner structure. In order to supply the air and heat-treated air from the air gap space to the chamber space, at least one distribution element fitted with slats is provided at the chamber floor.

The advantage of the technical solution is that the air temperature and humidity are supplied to the chamber space from the double wall area by distribution elements fitted with lamellae, which ensures a homogeneous distribution of temperature and humidity treated air in the whole chamber within ± 1 ° C.

BRIEF DESCRIPTION OF THE DRAWINGS

The technical solution is explained in more detail in the attached drawings, which show:

FIG. 1 is a plan view of a phytotron chamber FIG. 2 is a cross-sectional view of FIG

An exemplary embodiment is described on the applied phytotron chamber 10 shown in Fig. 1, where a double wall system with distribution elements is applied. The phytotron chamber 10 is formed by a multilayer peripheral thermal insulation panel 1. Inside the thermal insulation panel 1, air discharge systems 5 are provided within the ceiling soffit 10 for venting the space of the phytotron chamber 10. An internal boundary structure 2 is formed along the two inner longitudinal sides 10.1 of the chamber W. for example, zinc-plated sheet metal, which forms an air gap 3 (double wall) between the thermally insulating panel 1 and said inner structure 2. This inner structure 2 is fitted with distribution elements 4 fitted with lamellae 4.1 at the floor of the chamber 10. The shape of the slats 4.1 is designed according to the requirement for the velocity and direction of flow of the temperature and humidity of the conditioned air supplied through the gap 3 to the slats 4.1. The air temperature and humidity are fed to the space 3 via an inlet (not shown). An example of the shape of the slats 4.1 in the distribution element 4 is shown in Fig. 4 with the design parameters X, Y and the angle of rotation of the vane in the distribution element 4 - tab. 1. The current characteristics of the distribution elements 4 are shown in FIG. 5.

Industrial use

The phytotron chamber with a double wall is usable in stable boxes, in thermal chambers, or in special operations for the electrical industry, the medical industry and elsewhere where temperature and humidity requirements are required.
