Technical field
The present invention relates to greenhouse facilities technical fields, and in particular to a kind of greenhouse and its internal cool-down method.
Background technology
With being constantly progressive for society, traditional Agriculture Production Modes cannot meet the needs of modern civilization development,
Novel agricultural planting equipment is widely used.Greenhouse facilities is because it can not be limited by natural environment, in various regions
Highly important status is occupied in agricultural production.
High temperature, high humidity, intense light irradiation area, when inside greenhouse when the temperature is excessively high, be unfavorable for the growth of plant, usually need
Cooling processing is carried out to the inside in greenhouse, traditional greenhouse needs to expend a large amount of energy, cause to produce when being cooled down
Cost increases.
Invention content
Based on this, it is necessary to provide a kind of greenhouse and its internal cool-down method, cooling energy consumption can be reduced, to reduce
Production cost.
Its technical solution is as follows：
A kind of internal cooling method in greenhouse, includes the following steps：The Inside Air Temperature in greenhouse is detected；If warm

As shown in Figures 1 and 2, one embodiment of the present of invention discloses a kind of internal cooling method in greenhouse, including with
Lower step：The Inside Air Temperature in greenhouse is detected；If the Inside Air Temperature in greenhouse is greater than or equal to the first default temperature
Angle value then opens ventilation device, increases the inner air in greenhouse and the air-flow exchange area of outdoor air；Ventilation device is opened to arrive
Up to the first preset time, if the Inside Air Temperature in greenhouse still above or be equal to the first preset temperature value, make shading piece 310
Cover the sunlight face in greenhouse；The sunlight face that shading piece 310 covers greenhouse is set to reach the second preset time, if greenhouse
Inside Air Temperature still above or be equal to the first preset temperature value, then open forced cooling system；Wherein, the first preset temperature
Value is less than outside air temperature.
The internal cooling method in the greenhouse of above-described embodiment carries out the Inside Air Temperature in greenhouse using temperature sensor
It detects and testing result is transmitted to control device and handle, if the Inside Air Temperature in the greenhouse detected is pre- less than first
If when temperature value, then being not required to cool down to greenhouse, if the Inside Air Temperature in greenhouse is greater than or equal to the first preset temperature value
When, then ventilation device is opened, i.e., is opened the skylight structure 210 on the top structure 120 for being set to greenhouse ontology 100, greenhouse
The hot-air of interior floating is discharged outside to through the first ventilation opening 121, will be set in the side wall construction 110 of greenhouse ontology 100
Side window structure 220 is opened, and extraneous wind enters inside greenhouse through the second ventilation opening 221 and forms convection current, so that in greenhouse
The hot-air in portion can be swapped quickly with extraneous air, thereby reduce the temperature of inside greenhouse；Open ventilation dress
It postpones, by the first preset time, being detected to the air themperature of inside greenhouse and testing result being transmitted to control dress
It sets and is handled, if detecting, the Inside Air Temperature in greenhouse decreases below the first preset temperature value, closes ventilation device,
If in the first preset time period, detect that the Inside Air Temperature in greenhouse is still greater than or equal to the first preset temperature value, then
The shading piece 310 that will be close to the setting of top structure 120 is unfolded along the horizontal direction or longitudinal direction of greenhouse ontology 100, to right
The sunlight face in greenhouse is covered, and stops or reduce light exposing to inside greenhouse, so that the temperature of inside greenhouse
It reduces；After being covered to the sunlight face in greenhouse using shading piece 310, by the second preset time, to the inside in greenhouse
Air themperature is detected and testing result is transmitted to control device and handles, if detecting the Inside Air Temperature in greenhouse
The first preset temperature value is decreased below, then closes internal sunshade device and ventilation device, if detecting the inner air temperature in greenhouse
Degree is still greater than or equal to the first preset temperature value, then opens forced cooling system, quickly will be warm using forced cooling system
The internal temperature of room decreases below the first preset temperature value.The cool-down method of the internal temperature in the greenhouse of the present embodiment, temperature
Sensor is detected the temperature of the inner air in greenhouse, opens different devices in the different stages, takes segmented
The cooling-down effect to the inside in greenhouse is gradually increased in cooling mode, need to only open an energy in ventilation device or shading piece 310
The cooling demand for enough reaching greenhouse is just not required to open forced cooling system, reduces the energy loss needed for cooling, reduce life
Produce cost.
It needs to illustrate, the first preset temperature value can be adjusted according to actual demand, such as according to season
Difference and the differences of morning and evening be adjusted, can be 35 DEG C, can also be 20 DEG C, need to only meet the inner air temperature when greenhouse
When degree is more than the first preset temperature, it can be cooled down to the inside in greenhouse by opening corresponding cooling system, meanwhile,
First preset temperature need to meet the growth demand of plant；First preset time and the second preset time can according to actual demand into
Row adjustment, such as can be 5min, can also be 10min.
Optionally, after the step of making shading piece 310 cover the sunlight face in greenhouse, further include：To the inside in greenhouse
Intensity of illumination is detected, if the interior illumination intensity in greenhouse is less than or equal to the first default illumination intensity value, opens light filling
Device.After shading piece 310 covers the sunlight face in greenhouse, the light for exposing to inside greenhouse tails off, to protect
Card plant can be detected the intensity of illumination of inside greenhouse by sufficient illumination, optical sensor, when intensity of illumination is low
When the first default illumination intensity value, light compensating apparatus is opened, using light compensating apparatus supplementary light, ensures that plant can
By sufficient illumination.
Optionally, it includes step to open forced cooling system：Spraying device (not shown) is opened, nozzle is made to spray fog,
Accelerate the evaporation of the inside in greenhouse.When opening forced cooling system, it is first turned on the first switch part of spraying device so that
Nozzle sprays fog, for example, nozzle water spray, water mist is spread in inside greenhouse, is constantly evaporated during diffusion, from
And a large amount of thermal energy is absorbed, and then achieve the purpose that cooling.
Further, spraying device is opened, so that nozzle is sprayed fog, after the evaporation step for accelerating the inside in greenhouse
Further include：It opens spraying device and reaches third preset time, if the Inside Air Temperature in greenhouse is in advance still above or equal to first
If temperature value, then spraying device is closed, opens heat sink.It opens spraying device and reaches third preset time, in greenhouse
Portion's air themperature is detected, if detecting, the Inside Air Temperature in greenhouse decreases below the first preset temperature value, indicates drop
Temperature success, then close spraying device, if detecting, the Inside Air Temperature in greenhouse is still greater than or equal to the first preset temperature value,
Spraying device is then closed, heat sink is opened, fast cooling further is carried out to inside greenhouse using heat sink.Third is default
Time can be adjusted according to actual demand, such as can be 5min, can also be 10min.
Specifically, it includes the water pump for starting wet curtain 520 to open heat sink, under gravity so that water is in wet curtain
