4 Frequently Asked Questions about "Greenhouse solar phase change energy storage"

How does a solar greenhouse work?

When the indoor air temperature of the solar greenhouse drops at nighttime, the proposed wall and the ordinary wall conduct stored energy back to the inner surface, which then transfers heat from the inner surface of the wall to the indoor environment through heat convection and heat radiation.

How does solar radiation affect heat storage in a greenhouse?

During the daytime, the heat preservation quilt is removed; thus, solar radiation energy can enter the greenhouse through polyethylene vinyl acetate film and irradiate the inner surface of north wall directly, causing a significant increase in north wall temperature, which can significantly increase the heat storage of north wall.

How does a solar greenhouse wall affect indoor air temperature?

The heat storage and release capacity of the wall directly affects the indoor air temperature of the greenhouse. Previous research on the heat storage of solar greenhouse walls has shown that encapsulating and pasting PCMs onto the walls of the greenhouse effectively transfers the solar energy absorbed during the day to the interior of the wall.

How does a greenhouse wall reduce heat release capacity?

Then, the temperature difference between the middle layer of the wall and the inner surface of the wall reduces, leading to less heat into the greenhouse, which reduces the heat release capacity of the wall. However, the proposed wall of the CSG is added with an active heat storage system incorporating PCMs.
