Greenhouse water energy storage

Does a greenhouse need thermal energy storage?

To provide climate stability inside a greenhouse (especially in terms of indoor temperature and humidity), Thermal Energy Storage (TES) systems are required. They both reduce the heat demand of the greenhouse and stabilize a desired indoor micro-climate for plants cultivated inside.

Why do greenhouses use water?

Water is the most commonly used thermal mass in greenhouses for two reasons: it has the highest heat capacity per volume of any of readily available material, and it is cheap. The only needed component is a storage container – abundant commodities in our plastic-laden society.

How much energy can a greenhouse system save?

The maximum COP was attained as 16. From TRANSYS simulation, it was found that the system can save thermal energy as 46.2 kWh/m 2 of the greenhouse area per year while maintaining the indoor temperature at 12 °C. Economic assessment approved the system’s profitability.

What is seawater greenhouse?

Envel Technol Build Energy Effic ( 2006;2.) C. Chen, H. Ling, Z. (. Zhai, Y. Li, F. Yang, F. Han, S. Wei Environ. Prog. Sustainable Energy, 38 ( 3) ( 2019), p. e13029, 10.1002/ep.13029 Seawater greenhouse is a structure that enables crop growth in arid regions using both seawater and solar energy.

How can thermal energy storage improve climate stability in a greenhouse?

The exploitation of renewable energy sources such as solar, biomass, and geothermal heat can improve the sustainability of greenhouse cultivation and decrease its reliance on fossil fuels. To provide climate stability inside a greenhouse (especially in terms of indoor temperature and humidity), Thermal Energy Storage (TES) systems are required.

How much energy does a greenhouse need?

They used an energy balance method considering the soil heat storage with a contribution share of 13–19% for heating load requirements. From the results, it was found that the air mass flux of 0.012 kg/s.m 2 can culminate in nearly 84% of the diurnal energy requirement of the greenhouse to maintain the indoor air temperature at 18 °C.
