Description
Technical field
Field is efficiently utilized the invention belongs to greenhouse solar, is related to a kind of greenhouse collection hold over system and its operation method.
Background technology
To ensure the normal production of crop, cold snap need to be aided in greenhouse when wide geographic area carries out agricultural production
Heating, current coal-fired heating system (CFHs, coal fired heating system) and natural gas heating system (GFHs,
Gas fired heating system) be various countries greenhouse main heating system.Because space is big in chamber facility, heat insulating ability
The reason such as poor causes greenhouse heating huge energy consumption.For greenhouse winter nighttime temperature it is relatively low the problem of, for many years, numerous domestic
Scholar improves storage, emission capacity and has carried out numerous studies around how to improve utilization of the greenhouse to solar energy.In general, greatly
Part research is the thinking from enhancing soil or wall heat storage capacity.But this passive storage, exotherm, its storage are put
The lifting of heat energy power is than relatively limited, and Low Night Temperature especially time after midnight Low Temperature Problems are still without thorough solution.In recent years, by daytime
The solar energy of excess enthalpy stores the ground used in the new direction studied as Greenhouse System, such as vinyl house in a variety of ways
What is used in middle heat-exchange system, greenhouse can be stored in heat the polyene alkane resin material solar energy collection of water tank and thin solum
Solar water heating system of external used in hot device, small-sized greenhouse etc., these systems can be when nocturnal temperature be relatively low
Actively release energy into greenhouse, be increasingly becoming greenhouse area research focus.
For current research, Chinese patent CN106105905A discloses a kind of curved surface Nie Er lens light gatherings and facility agriculture
The solar thermal collection system that industry is combined.The system is combined using integral slip type concentrator with industrialized agriculture greenhouse, and energy will too
Sunlight high aggregation, realizes that solar energy and agricultural planting technique supply mutually utilization.But the system is excessively complicated, it is impossible to large area
Promote.Chinese patent CN104838924A discloses a kind of warmhouse booth solar air heat collection heat accumulation circulatory system.The system
Ground one layer of the lower berth heat insulating board in warmhouse booth, surrounding is turned up to ground, overall groove profile is formed, then in heat insulating board
Upper embedded heat collecting conducting pipe, underground thermal-arrest is sent to by the heat of solar energy air heat collector by blower fan, Fan pipeline, guide duct
Pipe is transmitted to soil horizon thermal-arrest, and the night solar air heat collection heat accumulation circulatory system is heated in the canopy of ground, and the system makes full use of
Solar energy, reduces thermal loss.
Present invention is generally directed to greenhouse in cold season fair weather, indoor temperature was usually above plant and suitably given birth to daytime
Long temperature, and the temperature at night often relatively low phenomenon, on the basis of forefathers study, it is proposed that a kind of greenhouse collection accumulation of heat
" surface cooler " is creatively changed into heat collector by system, the system, the heat storage in the high temperature air in daytime greenhouse
Into water, transfer of the heat in the time, spatially is realized, the utilization rate of solar energy is improved, solves night in winter greenhouse temperature
The problem of too low influence crop normal growth.
The content of the invention
A kind of greenhouse collection hold over system, including following part：As " surface cooler " 1 of heat collector, air circulation fans 2,
Water pump 3, pipeline 4, heat accumulation pond 5 and control system 6；
The heat accumulation pond 5 is located at below the ground level in greenhouse, and water pump 3 connects one end of supply channel 4, supply channel 4
The other end be connected with the water inlet end of surface cooler 1, water return pipeline 4 is connected with the water side of surface cooler 1, and the other end stretches into water storage
In pond 5, air circulation fans 2 are arranged on the side of surface cooler 1, are blown to surface cooler.
The control system 6 is mainly made up of air-temperature sensor, cooling-water temperature sensor and controller etc..
The surface cooler 1 is arranged on the eminence position of the greenhouse interior space, because the temperature of eminence air is higher, without prejudice to
The growth of warm indoor crops and the activity of staff.
The operation method of collection hold over system in greenhouse of the present invention is as follows：
(1) daytime, when the sensor in control system detects the temperature in greenhouse and the difference of heat accumulation pond reclaimed water temperature
During higher than setting value, water pump and air circulation fans are opened simultaneously, now, effect of the high temperature air in greenhouse in circulating fan
Under, the pipeline surface of " surface cooler " is transferred heat to, the temperature of " surface cooler " pipeline is raised；Water pump makes low temperature current simultaneously
Enter into " surface cooler " pipeline, heat is delivered in water rapidly by the specific surface area for utilizing " surface cooler " huge；So, just pass through
The circulation of water in the water in heat accumulation pond, realizes the thermal energy storage of warm room air redundancy on the locus of heat energy
Transfer；
(2) when the difference that the sensor in control system detects temperature in greenhouse and water temperature is less than setting value, close
Closed loop blower fan and water pump, collection heat-accumulating process stop.
Beneficial effects of the present invention are as follows compared with existing collection hold over system at present：
1. system architecture is simple, cost is low, easy for installation, reliable, can be in newly-built or original temperature indoor location.
2. by using the system, while solar energy is stored, inside greenhouse causes relatively wet because of the reduction of temperature
Degree is improved, and is more beneficial for the growth of plant.
