  The alarm protection device unit 130 is configured to turn off the power by operating the protection device when the various abnormality sensors 158 detect abnormality of various devices.

  The time setting unit 132 enables the start and stop of spraying at a specific time by setting the current time.

  FIG. 9 shows an operation flowchart of such a barn temperature and humidity control system 114.

  First, when power is supplied (S1), the operation of the barn temperature and humidity control system 114 is started (S2), and an initialization process is performed (S3).

  In the initialization process, time setting, 24-hour timer setting, spraying time setting, and spray stop time setting are performed.

  Next, it is selected whether spraying is performed automatically or manually (S4).

  When spraying by automatic setting is selected (S5), the temperature / humidity sensor is adjusted, and when the temperature exceeds the set temperature, automatic spraying is started, and when the temperature falls to the set temperature, it automatically stops.

  For example, in the summer, spraying is started when the detected temperature of each barn becomes a predetermined temperature or higher and a predetermined humidity or lower, and the spraying is stopped when the predetermined temperature and humidity are reached.

However, in summer, priority is given to temperature.
When the detected humidity falls below the set humidity, the spray is automatically sprayed, and when the set humidity is restored, the automatic stop is performed.

For example, spraying starts when the detected temperature of each barn falls below a predetermined temperature and below a predetermined humidity in winter, and stops spraying when the temperature reaches a predetermined temperature and humidity.
However, prioritize humidity in winter.

  When spraying by manual setting is selected (S6), a set spray time and a set stop time are designated, and a 24-hour timer is set.

  In this state, the spray device has the 24-hour timer turned on, and sprays and stops according to the spray time and stop time within the set period.

  If the 24-hour timer is turned off, it will stop.

  In both automatic and manual cases, if the sensor detects a failure (S7), for example, an abnormality in the system pressure, piping system, filter, water tank, slowing device, etc., a signal is sent to the controller to supply power Stop supplying and stop spraying.

When the failure disappears, if power is supplied again (S1), re-spraying becomes possible.
When such a barn temperature and humidity control system is used, the temperature, humidity adjustment effect, deodorization effect, air purification effect and the like in the barn can be achieved at low cost.

  In particular, the barn temperature in summer could be lowered from 36 ° C to 38 ° C to 30 ° C to 32 ° C.

  Moreover, the humidity in the dry barn in winter could be humidified from 25% to 30% to 50% to 80%.

  As a result, the germs and dust floating in the air due to drying in the barn are greatly reduced, and the respiratory infection rate of the ground can be greatly reduced.

  The present invention is not limited to the above-described embodiment, and can be modified into various forms within the scope of the gist of the present invention.

  For example, the nozzle device and the spray device of the present invention can be used not only for spraying in a barn, but also on roads, parks and other various places.
