Description
Technical field
The invention belongs to technical field of facility agriculture, are related to a kind of sunlight greenhouse structure, and in particular to a kind of active daylighting
Heat accumulating type heliogreenhouse.
Background technique
In recent years, with the continuous improvement of people's living standard and material requisite, people realize food security and to foods
Great variety has occurred in object structure, and market is growing day by day to the demand of greengrocery.Industrialized agriculture has become flourishing local warp
The big pillar industry of one for helping and increasing farmers' income.And as vegetables off-season cultivation heliogreenhouse, also obtain considerable hair
Exhibition and raising, heliogreenhouse is the subenvironment of vegetable cultivation, and heliogreenhouse only accomplishes scientific and reasonable construction, environment conditioning ability
It is good, it is just able to satisfy demand of the vegetable growth to photo-thermal reaction condition, is improved labor efficiency, avoids freezing cold disaster accident generation, reach
To the reasonable growth conditions of vegetables.
For a long time, scientific and technical personnel have carried out unremitting research and exploration, various novel daylight to heliogreenhouse modernization
Greenhouse development and greenhouse lighting, heat preservation and the application of accumulation of heat new technology are made that sunlight greenhouse structure optimization and performance boost
Major contribution.But using for the improvement of heliogreenhouse, the regulation of active light temperature and modernization design theory is insufficient, heliogreenhouse is still
So there are abilities of regulation and control it is weak, illumination patterns are uneven and whole year production is uneven the problems such as, seriously affected the anniversary of chamber crop
Efficiently production, tracing it to its cause mainly has following three aspects: the contradiction of the design of 1. heliogreenhouse thermal isolation and heat storages and optical uniformity is not
Easily solve.The design concept of heliogreenhouse need to construct heat-preserving wall and rear roofing to improve based on winter daylighting and thermal insulation property,
The design of the roofing elevation angle is using winter solstice solar elevation as design considerations afterwards.These designs are conducive to the daylighting of greenhouse severe winter and night protects
Temperature, but most season since rear roofing and insulation quilt are to the shield of warm indoor illumination, uneven illumination the problem of ratio in heliogreenhouse
It is more serious, especially rear portion crop daylighting is influenced bigger.In cold district, greenhouse azimuth uses azimuth design to the west, spring
After, due to the shading of rear roofing and insulation quilt, influence photosynthetic on chamber crop morning is very big at this azimuth, causes
Greenhouse whole year production ability is difficult to improve.2. existing sunlight greenhouse structure is unfavorable for greenhouse active accumulation of heat.At present after heliogreenhouse
Roofing mostly uses lightweight thermal insulation material, and rear roofing outer slope is larger, and insulation quilt can only be rolls-up onto front roof ridge position,
Very big shading region is formed on rear wall, when afternoon wall and thermal storage equipment need a large amount of accumulation of heats in the middle, shading causes amount of stored heat
It reduces.And greenhouse wall body and ground are blocked in plant growth, further weaken the heat storage capacity in greenhouse.3. pair heliogreenhouse
Structure innovation and the comprehensive application ability of regulation new technology be not strong.Greenhouse structure, the environment conditioning technology and equipment of heliogreenhouse
Efficient mated application technology shortcoming, lacks the research to the regulation of heliogreenhouse whole year production environment comprehensive, each new technology is caused to answer
Disconnection cannot give full play to due effect.And existing heliogreenhouse environment high efficiency regulatory mechanism and intelligent facility are owed
Lack, still fully effective progresss heliogreenhouse light, temperature coupling regulation and cannot efficiently produce, limit heliogreenhouse technology into one
Walk innovation and development.
In conclusion ability of regulation and control existing for heliogreenhouse is weak, environment temperature light distribution is uneven, and whole year production imbalance etc. is asked
Topic, is caused mainly due to existing sunlight greenhouse structure defect and Effective Regulation technical research deficiency.In order to solve to hinder sunlight
The technical bottleneck of room daylighting and accumulation of heat constructs mode by innovating heliogreenhouse, with active lighting technique, improves heliogreenhouse
Anniversary daylighting uniformity improves heliogreenhouse and actively stores emission capacity, to from now on using high-performance solar active collecting system
Heliogreenhouse has very important significance to modernization and intelligent direction development.
The information for being disclosed in background of invention part is merely intended to deepen the reason to general background technique of the invention
Solution, and it is known to those skilled in the art existing to be not construed as recognizing or imply that the information is constituted in any form
Technology.
