The dry data sheet is not all operating conditions
When assessing the cover material, a lot of attention is given to the light characteristics given in the dry state. However, a wet surface may be formed in the operation of the greenhouse. M WUR its material testing approach therefore also presents the separation of dry and wet conditions as an important issue. For the investor, this means that when comparing the material, the test condition must be added to the actual use.
The moisture on the surface is not to be called a material defect or a lack of a single device. To understand the situation, the relationship between the internal climate and the cover system is necessary. In preparation, the useful question that can be expected in the state of operation is how to track the phenomenon, and what is the subject of a technical examination. A single dry data or display photograph does not tell you that.
Light and moisture are two related issues
The light transmission of the cover and the behaviour of surface water may be specific, but it is attached to the same material in use. The comparison therefore requires clear concepts. What is the quality and condition? For technical decisions, you can then test your own application. The interested party shall not automatically treat all the light data contained in the description as valid for the same operating conditions.
If the project receives other climate action or use of umbrellas, an assessment of the coverage may also give rise to a new question. Systems should not be treated only as separate procurement items. The investor shall request an explanation of the relationship between the chosen cover and the internal climate management. The aim is not a general promise of complete elimination of the phenomenon, but an understanding of the state of inquiry, the task dealt with in the plan and the need for maintenance.
The path of moisture and the use of it are also relevant.
In assessing the design of the system, it is also a question of where the surface moisture is going and what conditions of use it concerns. The growing space and the service parts may give different tasks. The specific detail should be known from its own cover and branch plan. A general article cannot determine an appropriate node for all materials and designs, but it may make the link necessary for consultation visible.
The monitoring of the daily operator may be useful information in the subsequent assessment. When does the condition appear, in which area it is visible, and what other operational events have occurred? Data and technical monitoring for the observation shall be required if a technical decision is taken. Thus, local experience is not a general, unproven explanation, but a well-described information provided for the examination of the specific system.
For comparison, keep the conditions
When assessing two cover materials or two cover versions, the dry and wet test data should be provided separately where available. We're going to give you the missing information. In addition to the same cultivation purpose, the associated climate management or maintenance system may differ. The comparative sheet is designed to understand this, it does not create a complete greenhouse range from a single material quality, behind which the usage condition is not visible.
In the documentation of the accepted cover, remain the basis of the choice and the status of the test. The later operational evaluation can be linked back to this. If the planned and experienced situation differs, it will be known which conditions should be re-checked. The negotiation of condensation thus leads to a common understanding of the details of light, climate and system, based on the data of its own establishment, with no numerical result or general financial guarantee.
Questions to reconcile the project
- Does the data relate to dry or wet conditions?
- What surface and operating position are we looking at?
- How is the coverage connected to climate action?
