Description

A kind of greenhouse by solar heat that the heat accumulation function is arranged
Background technology:
We mainly call greenhouse by solar heat to the origin of heat in the greenhouse (comprising night) from the greenhouse of solar radiation usually.Energy saving sunlight greenhouse is China's original creation, and its energy-conservation culture technique occupies the first place in the world.As far back as phase early 1980s, energy-saving heliogreenhouse has been created in Haicheng City, China Liaoning Province and Wafangdian, and in the severe cold winter in 35 ° of north latitude~43 ° of areas, has successfully carried out not heating producing the production of thermophily gardening plants such as cucumber.Nineteen ninety, high-efficiency and energy-saving type vegetables in day-light greenhouse culture technique is put into the great agrotechnique exploration project of country " eight or five ", has further promoted the development of high-efficiency and energy-saving type greenhouse by solar heat, and area is by the 6667hm at the beginning of nineteen ninety 2, develop into 200,000 hm in 1998 2, the cultivation kind also by vegetables extend to flowers, view and admire woody plant and strawberry, gardening plants such as grape, peach.
(1) fundamental type of energy saving sunlight greenhouse
Energy saving sunlight greenhouse has polytype because of differences such as construction timber, bow member structure, roofing shapes.But can be divided into two classes substantially with regard to the roofing shape, first arch-shaped roofing is distributed in Beijing, Hebei, the Inner Mongol, the central and north, Liaoning Province etc. more; It two is a slope one upright shape roofings, is distributed in South Liaoning, Shandong, Henan one band more.Wherein more representational have following several structure type.
1. roofing arch form greenhouse, the long back of wall, short back: this greenhouse is the cob wall bamboo-wood structure, the high 0.8~1.0m of back wall, thick 0.6~0.8m; Backhouse face length 2.0~2.5m, thick 0.6~0.7m; Front roof is the semiarch type, on cover plastic film, cover paper night by cold-proof heat insulations such as, thin seat, straw mats.When general outside air temperature is reduced to-20~-15 ℃, indoorly still can maintain about 10 ℃.Have winter room light shine, characteristics that heat retention is strong, but after March, back roofing easily forms shade low light level district, influences illumination condition.
2. roofing arch form greenhouse, the short back of high back wall: the greenhouse is a bamboo-wood structure, span 6~7m, the high 1.5~1.8m of back wall, backhouse face length 1.0~1.5m, in high 2.4~2.6m.Because the back wall improves, the backhouse reduction of area is short, illumination in winter abundance not only, and also roofing shades after having reduced spring and autumn, has improved the room light photograph.But short because of the backhouse reduction of area, heat insulating ability reduces, and needs to strengthen the insulation measure.
3. steel bamboo mixed structure arch form greenhouse: greenhouse basic structure is similar with roofing arch form greenhouse, the short back of wall, high back.But the front roof bow member is steel pipe or reinforcing bar, no column.Steel bow member spacing is 60~90cm, and every 3m establishes a steel bar girder.This greenhouse structure is firm, the illumination abundance, and operation is convenient, and insulation daylighting is good, but cost is high slightly.
4. the steel bow member encircles round greenhouse: wall is the double-layer hollow brick wall behind this greenhouse, high 1.6~1.8m.Span 6~7m, in high 2.4~2.7m, backhouse face length 1.2~1.6m mostly is hollow pre-fabricated panels, the thick slag of upper berth 15~20cm.Bow member is welded with steel pipe and round steel.Bow member spacing 80cm fixes with longitudinal tie between bow member.This greenhouse room light heats soon according to evenly, and good heat insulating is easy to operate, can carry out various gardening plants winter and grow seedlings and High-efficient Production.
5. do not have adverse grade and encircle round greenhouse: no adverse grade greenhouse structure is simple, and cost is low.Back wall is brick wall or cob wall, and bow member fixes on column and the back wall with bamboo chip or bamboo pole.Room light shines, and heat soon, but heat-insulating property is poor.The suitable thermophilous spring in advance, delayed culture in autumn and cold-resistant gardening plant production in winter.
6. string formula greenhouse by solar heat: string formula greenhouse by solar heat claims a slope one vertical greenhouse again.About the high 2m of back wall, backhouse face length 1.5~2.0m, in high 3.0~3.3m.70 ° of the upright window angles of front roof, the high 0.6~0.8m of window, domatic angle is 21 °~23 °.Front roof is established a steel pipe truss every 3m, vertically draws No. 8 iron wires in 1 road every 0.4m, and two ends are fixed on the outer basis of gable.Behind the epiphragma, press the interior paired colligation of bamboo pole bow member of thin bamboo and film firm on the film.The general span in this greenhouse is 7.5~8.0m, and greenhouse space is big, the illumination abundance, and good heat insulating, and small investment, operation is convenient, high efficiency.
Summary of the invention
We develop a kind of greenhouse by solar heat that the heat accumulation function is arranged, and use warming plate; Three face wall bodies are built in the heat storing plate combination, preferably resolve the transformation of energy of the greenhouse by solar heat sun, storage problem.The projection angle and the canopy film fixing means of sunshine have been improved, for the construction of greenhouse by solar heat provides a kind of new pattern.
