Hair heat absorption reduces the indoor temperature of temperature；Present apparatus design is simple, and of low cost, energy consumption is relatively low, and automation is efficient, is applicable in
In general greenhouse, it is particularly wall-mounted on the greenhouse of hot windy area.
Greenhouse spray cooling system of the utility model based on Bernoulli effect includes spraying system and ventilating system, spraying
System includes water tank, compression pump, controller, more than one atomizer, temperature inductor, and compression pump passes through pipeline and storage
Water tank is connected to, and compression pump and the water-supply-pipe for being arranged in greenhouse internal upper part are connected to, and more than one atomizer setting is in water-supply-pipe
It goes up and communicates therewith, controller is connect with compression pump, temperature inductor respectively by conducting wire；Ventilating system includes air inlet, sky
4 or more air inlets are arranged in greenhouse bottom in air filter, wind deflector, air outlet, weather shield, and air filter setting exists
In air inlet, wind deflector is inclined at the wind outlet in greenhouse and positioned at air inlet, and air outlet is opened in top of greenhouse center, gear
Rain plate is arranged above air outlet.
Described wind deflector one end is connect by spud pile with land operations in greenhouse, and elevating lever one end fixes on the ground,
The other end is arranged on wind deflector for adjusting wind deflector angle of inclination, to control the wind direction of air inlet.
The weather shield is fixed on by supporting rod above air outlet.
The air outlet is hollow round table shape, and protrudes greenhouse top.
The weather shield is transparent material, keeps tilting with horizontal line.
When the present apparatus works, high temperature signal is sent to controller by temperature inductor, and controller starts compression pump simultaneously automatically
Make compression pump continue working 2 minutes, controller monitors the opening and closing of temperature and control pressure pump according to a conventional method；Compression pump is from water storage
It draws water, is pumped to after water is pressurizeed in several atomizers in case, atomizer manufactures water mist in greenhouse, and water mist is full of temperature
It is throughout the room；Water mist is quickly evaporated by the indoor gentle breeze that Bernoulli effect generates, and reduces indoor temperature.
The utility model has the beneficial effects that：
The utility model design is simple, easy to use, using Bernoulli effect and evaporation endothermic principle by the indoor temperature of temperature
Degree reduces, and whole process energy consumption is relatively low, rational utilization of water resources, and the spraying system and ventilating system of automation greatly improve

Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and examples, but scope of protection of the utility model
It is not limited to the content.
Embodiment 1：As shown in Figure 1, including spraying system based on the greenhouse spray cooling system of Bernoulli effect and logical
Wind system, spraying system include water tank 1, compression pump 2, controller 3,10 atomizers 6, temperature inductors 7, compression pump 2
It is connected to water tank 1 by pipeline, compression pump 2 is connected to the water-supply-pipe 4 for being arranged in greenhouse internal upper part, and 10 atomizers 6 are set
It sets on water-supply-pipe 4 and communicates therewith, controller 3 is connect with compression pump 2, temperature inductor 7 respectively by conducting wire 5；Ventage
System includes air inlet 8, air filter 9, wind deflector 10, air outlet 13, weather shield 14, and 4 air inlets 8 are arranged in greenhouse bottom
