Description
Technical field
The utility model relates to agricultural facility field, is specifically related to a kind of greenhouse by solar heat thin solum hold over system.
Background technology
Greenhouse by solar heat is the main horticultural greenhouse types that the supply of vegetables anti-season is carried out in the northern area of China.The key problem in technology of greenhouse production is environmental Kuznets Curves, and the temperature condition environmental condition that to be crop vital movement the most basic.Solar Greenhouse in Winter day temperature is higher, and nighttime temperature and ground temperature are all on the low side, very large on the impact of crop growth, usually occurs damaging to plants caused by sudden drop in temperature or freeze injury phenomenon, causes the growth of crop and the decline of yield and quality thereof.In numerous greenhouse heating modes, utilize the soil heating system of solar heat-preservation directly effectively can improve ground temperature, effectively can reduce energy consumption, reduce and pollute, improve the slow problem such as bad of crop growth, realize cost-saving synergistic.
Utility model content
In order to improve solar energy utilization ratio, strengthen sunlight indoor air temperature and ground temperature ability of regulation and control, the problem of the aspects such as simultaneously solution greenhouse low temperature season in the winter accumulation of heat of low cost and insulation, the utility model provides a kind of greenhouse by solar heat thin solum hold over system.
For achieving the above object, the technical scheme that the utility model is taked is:
Greenhouse by solar heat thin solum hold over system, comprises greenhouse by solar heat, also comprises ajutage, buffering air channel, radiating tube, centrifugal blower and air outlet, buries a radiating tube in the underground of greenhouse by solar heat underground every 0.5-2m, dark apart from ground 40-50cm; Centrifugal blower is positioned near top, the north side ridge height of greenhouse by solar heat, air outlet is positioned at base angle, greenhouse by solar heat south, ajutage is arranged on inside greenhouse by solar heat adverse grade and north wall, ajutage one end is connected with radiating tube by buffering air channel, the other end is connected with centrifugal blower, and described radiating tube one end is connected with air outlet.
The diameter in described buffering air channel is greater than ajutage and radiating tube.
As preferably, the supply air system be made up of centrifugal blower and ajutage is multiple.
As preferably, described air outlet is multiple.
The utility model has following beneficial effect:
1), arrange and multiplely get air port and air outlet, use multiple stage Small Centrifugal Fan, improve ventilation and heat exchanger effectiveness.
2), tuyere position is got: the installation site of centrifugal blower is near top of greenhouse ridge height, and temperature is here the highest, can reach 40 DEG C.Compared to getting tuyere position on ground, a large amount of subaerial heat is inhaled into underground, and subaerial air themperature reduces successful, but is unfavorable for plant growth, and does not make full use of top of greenhouse waste heat.For the Shenyang of north latitude 42 °, in the winter time sunny daytime, when outside air temperature is-15 DEG C, at the greenhouse by solar heat of span 10m, ridge height 5.5m, in noon greenhouse by solar heat, 1.5m eminence temperature can reach about 30 DEG C, and the temperature of 5.5m eminence can reach about 43 DEG C, and its temperature is the highest, heat is maximum.
3), air outlet position: the installation site of air outlet is positioned at base angle, south, greenhouse, and air outlet temperature about 20 DEG C, in the temperature range of warm season vegetable suitable growth.
4), arrange buffering air channel, make the allocation of the amount of air in different hot channel balanced, whole temperature of green house soil increases evenly.
5), radiating tube is arranged: radiating tube adopts that thermal conductivity factor is large, cost is low, the pipe of cement of easy construction or cement smoke pipe.Radiating tube setting direction is North and South direction, and length is less than greenhouse span, general 8-15m; Distance between radiating tube is 0.5-2.0m, is good, effectively can improves the heat storage efficiency of soil in whole greenhouse with about 1m.Radiating tube digs and buries depth as shallow simultaneously, is generally 40-50cm, not only can significantly improves the temperature about 3 DEG C of thin solum, promotes the growth of plant root, and reduces costs, and strengthens Solar Greenhouse in Winter productivity.
6), thin solum hold over system is when running, and can reduce the air humidity about 5% in greenhouse, contribute to reducing greenhouse disease and occur.
Accompanying drawing explanation
Fig. 1 is the top cross-sectional view of the utility model embodiment greenhouse by solar heat thin solum hold over system.
Fig. 2 is the north-south profile of the utility model embodiment greenhouse by solar heat thin solum hold over system.
Embodiment
In order to make the purpose of this utility model and advantage clearly understand, below in conjunction with embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1-2, the utility model embodiment provides a kind of greenhouse by solar heat thin solum hold over system, comprise greenhouse by solar heat 1, also comprise ajutage 2, buffering air channel 3, radiating tube 4, centrifugal blower 5 and air outlet 6, a radiating tube 4 is buried underground every 0.5-2m in the underground of greenhouse by solar heat 1, dark apart from ground 40-50cm; Centrifugal blower 5 is positioned near top, the north side ridge height of greenhouse by solar heat 1, air outlet 6 is positioned at the southern base angle of greenhouse by solar heat 1, ajutage 2 is arranged on side in greenhouse by solar heat 1, ajutage 2 one end is connected with radiating tube 4 by buffering air channel 3, the other end is connected with centrifugal blower 5, and described radiating tube 4 one end is connected with air outlet 6.
The diameter in described buffering air channel 3 is greater than ajutage 2 and radiating tube 4.
The supply air system be made up of centrifugal blower 5 and ajutage 2 is multiple.
Described centrifugal blower 5 is multiple.
This is concrete implements, by air circulating in the duct, can improve about 3 DEG C apart from 20cm depths, ground soil temperature.By drawing the test analysis of greenhouse internal and external environment temperature, greenhouse by solar heat thin solum hold over system can improve greenhouse temperature 1-2 DEG C.And in the winter time in Vegetable Production in Solar Greenhouse, higher soil temperature is often greater than temperature in guarantee vegetable growth, therefore, the utility model can significantly improve the winter production ability of vegetables, and average rate of growth reaches 13%-17%.From the accumulation of heat angle of system, centrifugal blower runs 5h daytime, calculate according to equation of heat balance, the amount of stored heat in unit are greenhouse accounts for about 15% of the total amount of stored heat in greenhouse, illustrates that the heat storage efficiency of this system is higher, has obvious effect to the warm indoor air temperature of raising and ground temperature, enhance the heat storing and heat preserving performance of greenhouse by solar heat, and improve the environment conditioning ability of greenhouse by solar heat, utilize solar heat-preservation to reduce energy resource consumption simultaneously, achieve low-carbon agriculture.This is concrete implements daytime greenhouse by solar heat thin solum hold over system and the waste heat of top of greenhouse can be entered by blower fan circulation and get air port, then by underground piping, by heat transmission be accumulated in thin solum.Night by air circulation flow by the thermal release of accumulation out, had both reduced the temperature of Greenhouse day again, also effectively raised temperature and the ground temperature at greenhouse night.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
