Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a water spray humidifier.

[Conventional technology]

2. Description of the Related Art Conventionally, in an air conditioning unit, a humidified space may be provided in the air conditioning unit to spray water by the purpose of supplying humidity to the conditioned air or reducing the temperature of the conditioned air due to sensible heat.

[Problems of conventional technology]

By the way, as spray nozzles of these water spray type humidifiers, generally, nozzles N ... N for spraying water in a conical cone shape are used as shown in FIG. Since it is divided into ducts, cone-shaped sprayed water droplets directly contact the humidification space inner wall surfaces A1, A
It is unavoidable that the water droplets W collide with 2 and become water droplets W and flow down along the inner wall. Further, when the nozzles are arranged in multiple stages as shown in the figure, the water droplets become bloated due to the collision of water droplets in the mutual spray interference portion. As a result, these drops also occur, and there is a drawback that efficient humidification cannot be performed.

[Problems to be solved by the device]

In view of the above drawbacks, the present invention has been made for the purpose of providing a water spray type humidifier in which sprayed water droplets are efficiently consumed for air humidification.

[Technology that has solved the problem]

That is, in the water spray type humidifier of the present invention, a spray nozzle for spraying water in a fan-shaped plane having a size that does not reach the inner wall of the humidification space of the air conditioning unit in the humidification space of the air conditioning unit is formed. The fan-shaped planes are arranged in multiple stages in parallel with the upper and lower walls of the humidification space and at intervals such that mutual water spray areas do not interfere with each other.

〔Example〕

 Next, an embodiment of this invention will be described.

1 is a side sectional view of an embodiment of the present invention, FIG. 2 is a sectional view taken along the line II-II of FIG. 1, and FIG. 3 is a plan view of the embodiment.

In the water spray type humidifier 1 of the present invention, as shown in FIGS. 1 to 3, spray nozzles 2 ... 2 for spraying water in a fan-shaped plane P are provided in a humidified space A of an air conditioning unit. P is arranged in multiple stages in parallel to the upper and lower walls A1 and A2 of the humidification space A, and at intervals so as not to interfere with each other's water spray area, facing the air flow (arrow X). .

In the above embodiment, the spread of the fan-shaped plane P of the spray nozzles 2 ... 2 is adjusted to an angle that does not directly reach the side walls A1, A2, A3, A4 of the humidification space A, including the sprayed water droplets that are pushed back by the air flow. Further, the spray pressure is set to a pressure that can oppose the air flow at the spray nozzle ejection port, although it depends on the air flow rate and the required humidification amount.
After the injection, the pressure is set to a windward direction to form a fan-shaped pattern.

[Operation] In this invention, the water droplets sprayed from the spray nozzles 2 ... 2 in the fan-shaped plane P shape against the air flow having a constant flow velocity (arrow X) are pushed by the air flow (arrow X) and eventually become the air flow. It is made to flow in the same direction (arrow X), and during this time, evaporation and humidification are performed by contact with conditioned air.

At this time, since the water spray has a fan-shaped planar shape, there is no mutual interference of spray water from the spray nozzles 2 arranged in multiple stages, and the water spray directly to the inner walls A1 to A4 of the humidification space A. Contact is also significantly reduced.

Therefore, most of the sprayed water droplets float in the air flow, and the enlargement of the water droplets is also prevented, so that efficient humidification can be performed.

By the way, when comparing the humidification efficiency with the cone-shaped spray nozzle shown in the conventional example, this one shows that
It was found that the conventional example is excellent in humidification efficiency of 25 to 30% and saturation efficiency of 40 to 50%, while the saturation efficiency was 30 to 40% and the saturation efficiency was about 50%.

〔effect〕

As described above, the present invention effectively prevents the spray water from flowing down due to the collision with the inner wall of the humidification space or from falling due to the enlargement of the water droplets, and it is possible to increase the drift time of the spray water droplets into the air flow, resulting in remarkable humidification efficiency. Can be increased.
