This is known to be a structure with good walls made from carefully chosen materials and roof top also made from special materials. The house is created in a way that it provides an environment where temperature can be influenced or controlled. The house roof top is made or constructed using transparent materials for example glass panes and also polythene materials. Dutch greenhouse fans provide airflow in all seasons.
The top part of the roof is constructed using transparent materials. The transparent materials can be polythene papers or glass panes. Some plants may require more than twelve hours of light while others may need less than twelve hours of light.
There can be small sheds or big shed used for industrial purpose. Miniature structures are sometimes referred to as cold frame. The external part of this structure is basically exposed to a lot of sunlight. This exposure to sunlight warms the plants grown inside the structure during winter seasons or cold days.
The advantages of lean to structure include being very close to your home and also it allows for close monitoring of plants. The disadvantages if lean are there limitation of sunlight entrance. The other kind of greenhouse is even span. It has pitched sides which are even and similar to house sides.
The advantage of this kind of structure is they are common and with even spacing. The disadvantage is that they contain overlapping panes. These overlapping panes increase chances of the structure leaking. The advantage of owning a greenhouse includes the following. One can probably starts some seeds earlier, the winter will over tender your plants and an individual can grow several exotic plants.
The use of these devices is advantageous to these structures because they cool the place to temperatures that are recommended for plants. The fans operate on a principle where heat is eliminated by using pressure difference. The pressure difference is generally created by temperature and wind gradients. Wind produced by such devices plays the key role.
But currently a smaller design of pane is used requiring more framework for supporting for some houses but depending on size. There are many forms of ventilation that can be used in such structures but the most common one is fan ventilation. Warehouse fans are faster in cooling than natural ventilation.
Fan ventilation provides a balanced and free flow of air through the houses in any kind of weather condition. The fan basically works in the following manner. The fan will exhaust heated air, slight vacuum will be created in that room that automatically draws cooler air from outside to the room through air louvers.
Air from outside can come in to the house through air louvers, open doors and also cracks. This system of ventilation has many benefits over the natural ventilation system. The key benefit being fans have the capacity to provide accurate and precise flow of air at a speed which is controlled by the computer regardless of outdoor wind speed.
