Today, we’ll be discussing Solar Heating For Greenhouse. Basically, a greenhouse is a process of producing vegetables or ornamental plants within tunnels or houses (plastic). The house or tunnels are lit by sunlight or electricity. They are heated or cooled by electric heating or cooling devices to be produced in non-normal seasons.
Vegetables in these greenhouses have environmental conditions that are suitable for vegetative growth, rich in temperature and intensity of light.
Inside the protected house, all environmental factors are controlled and adjusted to suit the growth of the plant in order to achieve the best productivity of the crop.
Well, they are the rays emitted by the nuclear reactions within the sun, which is energy and heat. Then, they reach the solar energy to the Earth through space in the form of bundles called a photon.
Generally, the photon is the primary particle, the quantum of light and all other forms of electromagnetic radiation and the holder of magnetic force
Uses Of Solar Heating For Greenhouse:
The role of solar energy in greenhouses depends not only on heating but also on the benefits of solar energy within the greenhouse, including heating.
As for the other benefits of solar energy inside the agricultural greenhouse are as follows:
All seasonal crops can be planted throughout the year in closed environments where greenhouses convert sunlight into heat, giving the ability of plants that need heat to grow in the winter.
Heating of greenhouses:
Solar energy is usually used to produce electricity to illuminate greenhouses but does not use solar energy for heating. It relies on gas or oil to maintain the necessary temperatures for plant growth.
In the cold winter months, solar greenhouses are designed to take advantage of solar energy for both heating and lighting.
The use of solar energy in drying grain and crops is one of the oldest and most widespread solar applications. The simplest and least expensive method is to spread grains and crops in the sun to dry after harvest.
But, the risk here is that crops and grains are damaged by birds, rodents, pollution. However, with the development of solar drying technology, there are advanced solar dryers that protect grains and fruits and reduce losses.
Moreover, they help accelerate the drying process and produce a better-quality product.
