Energy storage field cooling

Do radiative cooling membranes work in grain storage warehouses?

The field test to warehouses confirmed the excellent cooling performance of the radiative cooling membranes when applied to the grain storage warehouses, achieving significant temperature reduction and energy savings. However, the membrane's performance under different climatic conditions (i.e., grain storage ecological zones) remains unknown.

How does a radiative cooling membrane reduce mechanical cooling requirements in summer?

In simulation model, the radiative cooling membrane starts operating from the beginning of the year and the thermal capacity of grains generates a large “cold” energy storage which reduces mechanical cooling requirements in summer. Fig. 11.

Why is radiative cooling important for grain storage?

This tendency is highly beneficial for grain storage because radiative cooling exhibits its optimum cooling effect when the grain is most susceptible to deterioration and requires the highest level of cooling.

What is radiative cooling technology?

Radiative cooling technology dissipates heat to outer space through the atmospheric window. A radiative cooling membrane possessing spectrum-selective optical properties has been installed on the grain storage warehouses in Hangzhou, China for a field testing.

How much energy can a radiative cooling membrane save?

Results indicated that more than 68% of the energy can be saved by applying the radiative cooling membrane. Most of the energy is consumed during summer (from June to September).

How to evaluate the energy saving of air conditioning systems?

To evaluate the energy saving of air conditioning systems, the cooling set point of the model is 25 °C, equivalent to the required grain value of QLTS. The monthly air conditioning electricity consumption of the warehouses in each representative city of each ecological zone is shown in Fig. 11.
