Description

Water evaporative cold fan

The present invention relates to a water evaporative cold fan, and more particularly, to improve evaporation of water by forming a vaporization structure through which passage air is easily passed through a porous shell and several porous discs through a passage secured inside the vaporizer case. It relates to a water evaporative cold fan that allows.

Typical air conditioners include fans and air conditioners. Fans, however, simply circulate the hot air around them and do not provide coolness.

In addition, the air conditioner has a superior cooling power compared to the fan, but is expensive and consumes a lot of power during operation, causing long-term side effects such as cooling bottles.

Accordingly, a cold fan that can play an intermediate role between an electric fan and an air conditioner and has a low maintenance cost has been proposed.

The cold air blower uses the temperature difference between water and air and the heat of vaporization, and takes into account that the temperature difference between water and air is about 3 ℃ to 5 ℃ even at the same room temperature. After flowing down from the upper part of the absorbent pad to the lower part and then blowing the blown air through the water film of the absorbent pad, cold air is generated by evaporation of water. That is, the cold air fan uses the principle that the temperature of the air is lowered by the heat of vaporization of the water and the temperature difference between the water and the air.

While the general air conditioner operates by a compressor to consume about 1500 Watts of current, the cold air blower has a large power saving effect because only about 60 to 80 Watts are required for fan operation and water pump operation.

In the past, to take advantage of these coolers, coolers use ice, coolant, or cooling packs in water to cool the air when the water cools, and allow the air to pass through the wet water. However, if the ice or coolant or the cooling pack runs out of cold air, there is a problem that no longer generates a cool wind.

In order to solve this problem, the water evaporative cooler proposed to blow the cold air formed by the evaporation of water generated when the blowing air passes through the wet pad that is wet with water, as shown in FIG. There is a problem that the amount of blowing of cold air is less as the air passes.

The water evaporative cold fan has a problem in that the cold air is insufficient due to the slow evaporation rate of the water and the evaporation amount of the water because the blowing air is not smoothly flowed due to the obstruction of the wet pad.

In addition, the water evaporative cooler illustrated in FIG. 2 is configured to allow water to evaporate by blowing air passing through an evaporation filter when the water dispensed from the top wets the mesh type evaporation filter. Formed to secure the passage of the blowing air, but the flow path is short there is a problem that the evaporation of water is not made smoothly.

In addition, the water evaporative cold fan shown in Figure 3, after removing the moisture contained in the cold wind by using the dew condensation caused by the temperature difference between the temperature of the cold air discharged through the cold air discharge pipe and the temperature of the outside air is a pleasant air in the room. Although it is intended to be blown, there is a problem that the cold air of the cold air is weakened because the cold air discharge pipe is installed in an exposed state to the outside.

The outdoor air blower fan 24 operates when the power switch (not shown) installed in the cold air blower 2 is operated. The outside air blowing fan 24 allows the outside air to flow through the outside air pipe P2 and supplies the introduced outside air into the vaporizer case 41.

The purifier 12 is provided with a well-known filter (not shown) and a UV lamp (not shown) and the like to be able to filter and sterilize the inside of the bet pipe (P1). The purifier 12 filters the bet introduced through the bet pipe P1 by the operation of the bet blower fan 14 with a filter and purifies the bet by the UV lamp sterilizing the filtered bet again.

The bet blower fan 14 is installed in the bet pipe P1 between the purifier 12 and the vaporizer 40 so as to blow the bet passed through the purifier 12 and pass the vaporizer case 41. The bet blowing fan 14 allows the bet to flow along the bet pipe P1 and to be supplied to the room through the bet pipe P1.

And the condensate recovery unit 50 is connected to the water tank 32 by a recovery pipe (L2) connected to the recovery case (53).

The recovery case 53 is formed larger than the diameter of the bet pipe P1 so that the condensed water hit by the recovery network 52 can fall. The condensed water collected in the recovery case 53 is stored in the water tank 32 through the drain port 54 to which the recovery pipe L2 is connected.

Hereinafter, the effect | action of this invention made as mentioned above is demonstrated.

First, power is applied to the cold air blower 2 so that the internal and external

air blowing fans

14 and 24, the purifier 12, and the water pump 34 of the cold air blower 2 operate.

Accordingly, the internal and external air flows into the vaporizer 40 of the cold air blower 2 through the internal and external air pipes P1 and P2 by the operation of the internal and external

air blowing fans

14 and 24.

The internal and external air introduced through the internal and external air pipes P1 and P2 moves inside the carburetor case 41 along the internal air pipe P1 and is discharged into the room, and the outdoor air is supplied to the carburetor case 41. And then discharged back to the outside.

The inside and outside air flowing into the inside and outside air pipes P1 and P2 by the operation of the inside and outside

air blowing fans

14 and 24 is filtered by the filter in the purifier 12 and sterilized by a sterilizer such as a UV lamp. After the bet is moved along the bet pipe P1.

The outside air is filtered by the outside air filter 22 and then supplied to the vaporizer case 41 and guided by the conical body 48 so that the flow rate is increased. Accordingly, the outside air is quickly discharged to the outside through the carburetor case 41 and the outside air pipe (P2).

At this time, the water stored in the water tank 32 is supplied to the branch portion 36 through the water pipe (L1) by the operation of the water pump 34. Water is uniformly distributed to both sides at the branch 36 of the water pipe L1 and then sprayed through the spray pipe LS installed inside the vaporizer case 41.

Several spray nozzles 42 installed in the spray pipe LS spray water like mist. The water to be sprayed is absorbed by the porous disc 44 and the porous shell 46 forming the vaporization portion 47 of the bet pipe P1 passing through the vaporizer case 41.

Accordingly, the bet pipe P1 covered by the porous disc 44 and the porous sheath 46 is always kept wet with water.

The porous disc 44 and the porous sheath 46 allowing the bet pipe P1 to be wetted are subjected to negative pressure by outside air passing through the vaporizer case 41 at a constant flow rate.

Water subjected to negative pressure by the high flow rate of the outside air is evaporated from the porous disk 44 and the porous shell 46.

That is, Bernoulli's principle works when the negative pressure due to the flow rate of the outside air is formed in the porous disk 44 and the porous shell 46. In other words, Bernoulli's principle is applied to the carburetor when the flow velocity increases, the dynamic pressure increases in proportion to the square of the speed and the static pressure decreases as the dynamic pressure increases.

In addition, the porous disk 44 and the porous shell 46 not only increase the heat transfer area, but also facilitate the maintenance and transmission of the negative pressure formed on the Bernoulli principle.

Accordingly, the bet pipe P1 cooled while the water absorbed in the porous disc 44 and the porous shell 46 evaporates lowers the temperature of the bet moving inside.

Accordingly, the bet whose temperature is lowered by the evaporation of the water absorbed in the porous disc 44 and the porous shell 46 while passing through the bet pipe P1 passes through the condensate return unit 50. At this time, the condensed water contained in the bet falls while hitting the recovery network 52 inside the recovery case 53 to form water droplets.

When the condensed water formed in the recovery network 52 falls, the condensed water is discharged through the drain port 54 and then stored in the water tank 32 by the recovery pipe L2.

Since the bet passing through the condensate recovery unit 50 is supplied to the room in a state where moisture is removed, indoor humidity can be kept comfortable.
