What is the energy saving capacity of Korean greenhouse screens?

Screen thermophysical, radiometric and aerodynamic properties were employed. TRNSYS model was used to estimate energy saved capacity of Korean greenhouse screens. Screen thermal performance and energy cost was evaluated by TRNSYS. Multilayer aluminized surface screen shows about 60 % energy saved.

What are energy screens in a greenhouse?

2.4. Energy saved and energy cost Energy screens are opaque or transparent construction materials of the greenhouse that serve as main barriers within the indoor microclimate (more than a single zone; therefore, they are responsible for thermal gain or loss, which directly influences energy consumption and crop thermal comforts.

What is the IEA photovoltaic power systems programme?

The IEA Photovoltaic Power Systems Programme (IEA PVPS) is one of the TCP’s within the IEA and was established in 1993. The mission of the programme is to “enhance the international collaborative efforts which facilitate the role of photovoltaic solar energy as a cornerstone in the transition to sustainable energy systems.”

What are the radiometric properties of greenhouse energy screens?

The radiometric properties of greenhouse energy screens are influenced based on the following screen features, which include surface symmetry and asymmetric, screen layer structures, material thickness, presence of aluminized strips or aluminized surface, and homogeneity.

Do greenhouse climate screens have energy retention capacity?

This process enables the evaluation of the energy retention capacity of various greenhouse climate screens within the TRNSYS model, by considering the screens’ thermophysical, radiometric, and aerodynamic properties. These screens properties play a crucial role in examining the annual energy demand and energy-savings.
