The heating task begins with the purpose of cultivation
A greenhouse heating demand cannot be established merely from its base area. First, it is necessary to determine the period during which the crop uses space and the internal state to be maintained. The issue of winter production, the extension of the season and the protection of the installed stock in an extraordinary cooling process is different. The investment programme should therefore include a special description of the day and night objectives and the temporary derogation at which stage it is possible to take place. These are cultivation decisions; the mechanical designer can establish a consistent system from these and on-site data.
Cover and weather are system data
The same size of greenhouses can also cause differences in cover, geometry, air lock and asterisk operation. The local external climate is not replaced by another gardener's previous account. For technical coordination, identify the design, weather conditions and operational conditions of the equipment. If a closed position of the power screen is assumed, the required air exchange and mating arrangements shall be clarified for the same calculation. M WUR a location-dependent design approach and Dalsem its integrated climate systems point out that the building and technology can be assessed together.
Peak performance and annual consumption specific issue
The performance required in the coldest test situation and the energy use of the whole year support two different decisions. The former helps control capacity and heat distribution, the latter being necessary for the operational plan. A large nominal heat producer alone does not tell us how much energy the garden will consume. The customer should also ask for an explanation of how the system handles the part load, the different needs of several zones and the loss of heat sources. The reserve shall be assigned to a specific position: which part of operation remains operational, which target condition and what available energy source.
The basis of the offer should be verifiable
A suitable offer not only lists the name of the equipment but also sets the basis for the calculation and the commitment limit. The task of heat generation, distribution network, heat output, regulation, electricity supply and testing must be seen separately. The actual available capacity shall be checked at the planned heat source and the assumed proximity is insufficient. When preparing the transfer, the measuring sites should also be defined: later, the thermal source failure can be separated from the internal distribution or control problem. If the production programme changes, the previous scale should also be reassessed.
What will change if the production season is longer?
If the investor only plans to operate from spring to autumn, and then wants winter operations later, the change does not just mean more hours. The intended target condition and the weather conditions under consideration may also change. In such cases, it is appropriate to require a specific comparative version of the heat source, heat output and supply conditions. The original offer shall remain valid if it clearly shows which production programme it is intended for and which subsequent claim was not included. The new system boundary should be confirmed on both sides before the order is modified.
Questions to reconcile the project
- For which period of production and internal destination is the heat demand tested?
- What is the coverage, umbrella, and airchange condition assumed by the calculation?
- Which heat source capacity has been verified and which condition is maintained by the reserve?
