What is a solar greenhouse?
Although all greenhouses are "solar" in that they use the sun to provide a growing environment for plants, the term "solar greenhouse" usually concerns a passive solar greenhouse. Passive solar greenhouses differ from traditional greenhouses in several important ways. Passive solar greenhouse uses only heat and light from the sun, and traditional greenhouse uses gas, propane or electric heat at night or during winter to provide plants with sufficient heat. Passive solar greenhouses must be oriented to the equator. They also use stone or large water containers to absorb solar heat during the day and distraction at night and use some type of insulation and double glass glass.
Traditional greenhouses use electric thermal lamps, floor heaters, propane heaters or other types of heating equipment during winter, and Nanoc to ensure sufficient greenhouse heatH plants, but a real passive solar greenhouse relies on the sun and natural components. Many solar greenhouses are constructed with a wall -oriented wall made of masonry to absorb daylight heat and release it all night; The remaining two walls are usually partially or completely masonry. Each square foot (929 square cm) a glass -oriented glass requires £ 150 (68 kg) of stone or brick material. Placing buckets, bathtubs or puddles strategically in the greenhouse allows water to absorb and release the heat of the sun in the same way. Each square foot (929 square cm) a glass -oriented glass requires 4 gallons (15.1 liters) of water; Containers should be dark colors and strategically placed throughout the greenhouse.
In order to be effective solar greenhouse, some kind of insulation is required in most environments. The east part of the roof and all walls should be a covered substance or other material with the thermal resistance value or hOutnut r to 19. If a passive solar greenhouse sits on the base, it must also be very well isolated. When the greenhouse is on the board, the board should be isolated both the greenhouse and anywhere where there is a crack or opening.
Passive sun greenhouse requires dual glazing with night insulation. One glazed glass will not be able to maintain enough heat for other passive elements-the water and stone-hungry elements to do their work. The only part of the glass part of the greenhouse, which should not be glazed, is two -thirds of the roof to allow full effects of the sun during the winter months. During the summer months, protection may be necessary in the form of discharging or fabric.
