Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hot air/cold air generator used in a vinyl house or the like.

[Prior Art and Its Issues] For example, in strawberry cultivation, a method is used in which seedlings in a nursery are separated and transplanted onto a flat bed in a greenhouse.
In this case, if the seedlings in the nursery are cooled before being separated and transplanted, they will immediately grow larger when separated and transplanted, so the inside of the nursery house is cooled with a cooling device.

Conventionally, this type of cooling device has used a refrigerator using a refrigerant. Although this cooling device is effective in shortening the strawberry cultivation period, it is expensive because it requires a compressor and a motor to operate it. Furthermore, despite the high cost of purchasing this cooling device, its usage period is limited to a short period of time, and the cost of producing strawberries on a small scale would be too high, making it impossible for ordinary strawberry farmers to introduce it.

[Purpose of the invention] The purpose of the invention is to provide a hot air/cold air generating device that has a simple and inexpensive structure, low running costs, and is comparable in cooling capacity to a cooling device using a conventional refrigerator. It is something to do.

[Structure of the device] The present invention includes: a partition body provided in a housing; a heat exchange chamber and a drip removal chamber formed by the partition body and partially communicating with each other; and outside air communicating with the heat exchange chamber. An inlet; A fan that introduces outside air into the heat exchange chamber from the outside air inlet; A water sprinkler provided in the heat exchange chamber; A heat exchange device provided below the water sprinkler; A fan provided in the drip removal chamber This hot air/cold air generator is equipped with an air supply port; and a delivery cylinder that is connected to the air supply port and sends heat-exchanged air to the outside.

The partition body generally extends downward from the upper wall within the housing, and the communication portion between the heat exchange chamber and the drip removal chamber is provided at the lower part of the housing. Note that as long as a heat exchange chamber and a drip removal chamber can be formed and ventilation is good, there is no limitation to this structure, and other structures may be used.
The heat exchange chamber and the dripping chamber are communicated with each other directly or through a member such as a vent pipe.

Although the fan is generally provided at the outside air inlet, it can also be provided at the air inlet or on the way from the outside air inlet to the air inlet.

The water spray body generally has a structure in which a large number of water spray holes are provided in a water pipe and sprays water in a shower-like manner, but it may also have a structure in which water is sprayed in the form of a mist in order to further improve heat exchange efficiency.

The structure of the heat exchange device is not particularly limited as long as it can lengthen the contact time between water and air and make it larger than the contact area. For example, a structure in which a large number of nets are stacked in multiple stages at predetermined intervals, a structure in which a large number of irregularly shaped chips are housed in a container made of wire mesh, etc.
Or, instead of wood chips, a suitable amount of glass wool, steel wool, silica, etc. is used in the structure.
According to this method, it is not necessary to apply water pressure to the extent that it causes water smoke, and even if the water pressure is low, the contact area between water and air becomes large, so that sufficient heat exchange occurs.

Note that the motor that drives the fan must have a certain amount of horsepower to obtain sufficient air flow, but even if the horsepower is sufficient, if the ventilation resistance of the heat exchanger is too large, the air flow may not be sufficient or the fan motor may become overworked. Therefore, the heat exchange device should have a structure with good air permeability and water permeability to the extent that the residence time of water can be maintained for a long time.

The base end of the blow cylinder may protrude from the air feed port toward the dripping chamber. In this case, the air supply resistance increases and the amount of air supplied decreases slightly, but on the other hand, the residence time of the air in the drip removal chamber becomes longer, making it easier for water droplets to condense on the wall surface of the drip removal chamber, resulting in an excellent drip removal effect.

Note that in winter, the temperature of groundwater is higher than the outside air, so the above device can also be used as a hot air generator. It can also be used as a hot air generator by using hot water heated in a boiler.

Furthermore, it is also possible to provide a temperature sensor at a location inside the house where cold air or hot air is sent, and use this temperature sensor to operate and stop the fan to adjust the temperature inside the house.

[Example] The present invention will be explained in more detail based on an example shown in the drawings. FIG. 1 is a partially cutaway schematic perspective view of an embodiment, and FIG. 2 is a schematic sectional view of the heat exchange device.

On both sides of the interior of the housing 1, partition walls 2 and 2a are vertically disposed from a ceiling wall 10 of the housing 1. The lower ends of the partition walls 2, 2a are located slightly above the bottom 11. The inside of the housing 1 is partitioned by the partition walls 2, 2a, and a heat exchange chamber 3 is formed in the center, and dripping chambers 4, 4a are formed on both sides of the heat exchange chamber 3. The heat exchange chamber 3 and the drip removal chambers 4, 4a communicate with each other below the partition walls 2, 2a. A drain pot 12 is provided at the bottom 11 of the housing 1, and a water level adjustment pot 13 is provided at a position slightly above the drain pot 12 on the side wall 40b of the housing 1.

The ceiling wall 10 of the housing 1 has an outside air inlet 5.
is provided, and the outside air inlet 5 communicates with the heat exchange chamber 3. A heat exchange chamber 3 is located above the outside air inlet 5.
A fan 6 for introducing outside air is provided at the fan 6 and is driven by a motor M.

A water sprinkler 7 is installed in the center of the heat exchange chamber 3 in the height direction.
has been installed. The water spray body 7 uses pipes to form a rectangular frame, and an appropriate number of intermediate pipes 7 are installed between two opposing sides 71 and 72 at intervals that do not hinder ventilation.
3 is constructed, and an appropriate number of water sprinkling holes 74 are provided on the lower surface of the frame and the intermediate pipe 73. The pipes on the two opposite sides 71 and 72 have a larger diameter than the other pipes, and serve as a water tank. Each pipe is connected to each other, and air can easily pass through the sprinkler body 7, so there is no burden on the fan. Note that 101 is a water pipe that communicates with the water spray body 7.

A heat exchange device 9 is installed between the partition walls 2 and 2a below the water spray body 7. The heat exchange device 9 includes a cylindrical housing frame 91, and the upper and lower sides of the housing frame 91 are provided with sealing bodies 92 and 93 made of wire mesh.
Steel wool 9 is provided inside the housing frame 91.
5 is housed at a density that does not impede ventilation even when it contains water.

Air inlets 41, 41a are provided at two horizontal locations on the side walls 40, 40a of the drip removal chambers 4, 4a, respectively. The air supply cylinder 8 is inserted through and fixed to the air supply ports 41 and 41a.

(Function) FIG. 3 is a schematic diagram showing the state of use. The operation of this embodiment will be explained with reference to FIGS. 1 to 3.

A hot air/cold air generator is installed inside or outside the house, and an air diffuser 100 is installed inside the house. The air diffuser 100 is made of a flexible synthetic resin sheet, and expands into a cylindrical shape due to air pressure caused by air supply.

The pumped up groundwater is introduced from the water pipe 101 to the water sprinkler body 7, and is sprinkled in a shower-like manner from the water sprinkling holes 74 provided in the water sprinkler body 7. Sprinkled water enters the housing frame 91 of the heat exchanger 9 and passes through the steel wool 9.
5 gets wet and falls downward.

At the same time, the motor M is activated to rotate the fan 6, and outside air is introduced into the heat exchange chamber 3 from the outside air introduction port 5. The introduced outside air passes through a shower of cooling water,
Next, it passes between the steel wool 95 wetted with water and is further blown against the cooling water collected in the bottom 11 to perform heat exchange and become cold air into the drip removal chambers 4, 4a.
is introduced into the air diffuser pipe 10 from the air supply ports 41, 41a.
Air is supplied to 0. At that time, the cold air containing a large amount of moisture condenses on the side walls 40, 40a and the partition walls 2, 2a as shown by the arrows, the amount of moisture contained in the cold air decreases, and water droplets exit outside. do not have.

The air diffuser 100 is provided with a large number of exhaust ports 102, and cold air is discharged into the house from the exhaust ports 102. Note that if the water level adjustment pot 13 is opened, the water level in the housing 1 will not exceed a certain level, and overflow of water can be prevented.

The present invention is not limited to the illustrated embodiment, but can be modified in many ways within the scope of the claims.

[Effect of the idea] The present invention has the above configuration and produces the following effects.

(a) A hot air/cold air generator is a device that generates cold air or warm air by applying outside air from a water sprinkler installed in a heat exchange room to the water being sprinkled and the water in the heat exchange device to exchange heat. It has a structure that allows the air to be discharged from the housing from the mouth, and does not require a compressor or associated equipment to produce cold air or hot air, and can be manufactured at low cost. Additionally, running costs such as electricity bills can be reduced significantly, and its cooling capacity is comparable to conventional cooling devices.

(b) In a structure in which heat is exchanged by exposing outside air to water, the air that undergoes heat exchange contains a large amount of moisture. If this is discharged as is, it may cause rust on other attached equipment or cause water droplets to be discharged into the house. However, in the present invention, since a drip removal chamber is formed, most of the moisture condenses inside the drip removal chamber, the amount of moisture in the discharged air decreases, and almost no water droplets are discharged from the air outlet. The above-mentioned inconvenience does not occur.

(c) Water is sprayed toward the heat exchange device, and most of the heat exchange is done by the heat exchange device, so sufficient cooling capacity can be obtained regardless of the water pressure of the water spray.
