Air port；When cooling mechanism work according to the indoor temperature value of temperature, the input wind regime of air hose is controlled in the first wind regime, the second wind regime
Between switch；The air that the wet curtain lets out air port output to air hose carries out cooling and forms cold air to reduce greenhouse temperature.
First wind regime is air blower；Second wind regime is refrigeration machine.
When cooling mechanism work, the air hose is first input wind regime with air blower, when cooling mechanism work, if greenhouse
Temperature more than threshold value, then the input wind regime of air hose be air blower, if greenhouse temperature in threshold value hereinafter, if air hose input wind regime
For refrigeration machine.
The air hose endcapped；The air port of letting out extends along air hose；It is described let out at air port be equipped with for adjust let out air port
The shutter of air output.
The shutter along air hose be divided into it is multiple can separately adjustable openings of sizes tune wind section；Tune wind close to air hose beginning
Section opening is big；Tune wind section opening far from air hose beginning is small；It is each that wind section is adjusted to let out air port to letting out air port air output and be adjusted such that
Each section of air output tends to be uniform.
The shutter is located at wet curtain and lets out between air port；The wet curtain is adjacent with the output end of water pump；Work as cooling mechanism
When work, the water pump draws water from pond and water is sprayed at wet curtain.
The control module includes programmable controller；The temperature measurement module is connected with control module；The temperature measurement module
Including being set to the indoor multiple temperature sensors of temperature；When greenhouse temperature drops to the attainable refrigeration of air blower and warm curtain cooperation institute
When lower limit, if you need to further cool down, then the input wind regime of air hose is switched to refrigeration machine by control module.
Compared with prior art, the invention has the following advantages: simultaneously using refrigeration machine-wet curtain integrated device structure
Can there are wet curtain fan mode and refrigeration machine-wet curtain fan to work at the same time mode two in greenhouse in conjunction with the use of programmable controller
Kind cooling method carries out setting application according to practical cooling demand, and comprehensive two kinds of equipment advantages solve wet curtain fan refrigeration effect
Excessive problem that fruit is undesirable and refrigeration machine cooling consumes energy；Refrigeration machine-wet curtain fan works at the same time under mode, and dry air is logical
Wet curtain is crossed, its humidity can be improved after moisture evaporation, the problem for avoiding refrigeration machine cooling temperature indoor humidity too low；It is sent using ventilation duct
Wind, each section air circulation and cooling extent are more uniform in greenhouse.
Detailed description of the invention
The present invention is described in more detail with reference to the accompanying drawings and detailed description:
Attached drawing 1 is schematic diagram of the invention；
In figure: 1- temperature measurement module；2- control module；The first wind regime of 3-；4- air hose beginning；The second wind regime of 5-；6- water pump；7- water
Pond；8- air hose；9- shutter；10- wet curtain；11- control module；The greenhouse 12-.
Specific embodiment
As shown in Figure 1, refrigeration machine-controllable cooling system of wet curtain integrated greenhouse, the drop of the controllable cooling system in greenhouse
Warm mechanism includes control module 11, temperature measurement module 1, the first wind regime 3, the second wind regime 5, air hose 8 and wet curtain 10；First wind regime
3, the outlet air end of the second wind regime 5 is communicated with air hose beginning 4；The wet curtain is set in greenhouse 12 and is arranged along air hose 8；The air hose
Side-walls let out air port equipped with direction wet curtain；When cooling mechanism work according to the indoor temperature value of temperature, the input of air hose is controlled
Wind regime switches between the first wind regime, the second wind regime；The wet curtain to air hose let out air port output air carry out cooling formed it is cold
Air is to reduce greenhouse temperature.
First wind regime 3 is air blower；Second wind regime 5 is refrigeration machine.
When cooling mechanism work, the air hose is first input wind regime with air blower, when cooling mechanism work, if greenhouse
Temperature more than threshold value, then the input wind regime of air hose be air blower, if greenhouse temperature in threshold value hereinafter, if air hose input wind regime
For refrigeration machine.
The air hose endcapped；The air port of letting out extends along air hose；It is described let out at air port be equipped with for adjust let out air port
The shutter of air output.
The shutter along air hose be divided into it is multiple can separately adjustable openings of sizes tune wind section；Tune wind close to air hose beginning
Section opening is big；Tune wind section opening far from air hose beginning is small；It is each that wind section is adjusted to let out air port to letting out air port air output and be adjusted such that
Each section of air output tends to be uniform.
The shutter is located at wet curtain and lets out between air port；The wet curtain is adjacent with the output end of water pump；Work as cooling mechanism
When work, the water pump draws water from pond and water is sprayed at wet curtain.
The control module includes programmable controller；The temperature measurement module is connected with control module；The temperature measurement module
Including being set to the indoor multiple temperature sensors of temperature；When greenhouse temperature drops to the attainable refrigeration of air blower and warm curtain cooperation institute
When lower limit, if you need to further cool down, then the input wind regime of air hose is switched to refrigeration machine by control module.
In this example, the programmable controller carrys out real-time detection with being installed on the indoor multiple temperature sensors of temperature and connect
Room temperature, while its work for also controlling air blower, water pump, refrigeration machine.When the temperature is excessively high, programmable controller first starts
Air blower and water pump are cooled down with wet curtain fan mode；Temperature drop to wet curtain fan can freeze minimum temperature when (pass through reality
Detection is usually at 26 DEG C), starting refrigeration machine, which is worked at the same time, is reduced to required temperature value for warm room temperature.
Pond is set in this example, in greenhouse can be used ice water or underground water to further decrease wet curtain temperature, can not only be quick
When reducing gas flow temperature when air blower air-supply, and refrigeration machine institute's air output can be made by wet curtain, the wet curtain of low-temperature condition
It can cold wind fast cooling to refrigeration machine, moreover it is possible to enhance refrigeration machine and send out moisture content in air-flow.
