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.

Conventional cooling systems use refrigerators that use refrigerants to cool outside air and discharge it into the greenhouse. Although this cooling device is effective in shortening the strawberry cultivation period, it requires a compressor and a prime mover to drive it, making the device expensive. Also,
Although this cooling device is expensive to purchase, it can only be used for a short period of time, and the cost of producing strawberries on a small scale would be too high, so it could not be installed by ordinary strawberry farmers.

[Purpose of the invention] The present invention is a hot air/cold air generator that has a thermally efficient structure, is less expensive than conventional equipment with the same capacity, has lower running costs, and is comparable in cooling capacity to conventional cooling equipment. The purpose is to provide the following.

[Structure of the invention] The structure of the invention taken to solve the above problems and achieve the purpose is as follows. That is, the present invention includes: a housing; a heat exchange chamber and a drip removal chamber that are divided and formed by a partition provided in the housing and communicate with each other in part; an outside air inlet that communicates with the heat exchange chamber; ; A fan that introduces outside air into the heat exchange chamber from the outside air inlet; A water sprinkler and a heat exchange device provided in the heat exchange room; An air supply port provided in the drip removal chamber; A fan connected to the air supply port; This hot air/cold air generator is equipped with: a sending cylinder that sends the heat-exchanged air to the outside; a water circulation device; and a water temperature adjustment device that adjusts the temperature of the water sent to the sprinkler body.

The heat exchange chamber and the dripping chamber communicate 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 structure of the heat exchange device is not particularly limited as long as it can lengthen the contact time between water and air and widen 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.

The motor that drives the fan must have a certain amount of horsepower to be able to blow enough air, 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 will not be able to blow enough air. Therefore, it is preferable that the heat exchange device has a structure with good air permeability and water permeability within a range that does not hinder heat exchange.

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.

As the water temperature adjustment device, a refrigerator or a heater equipped with a heater may be used. If a water temperature adjustment device or a fan is controlled by a temperature sensor, it is also possible to adjust the temperature inside a vinyl house, etc.

[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.

(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 refrigerator 202 is driven to introduce the water in the water tank 201 into the refrigerator 202 and cool it, and the water pipe 203
from there to the water sprinkler 7. Cooling water is then sprayed in a shower form from the water sprinkling holes 74 provided in the water sprinkling body 7. The sprayed water enters the housing frame 91 of the heat exchange device 9, wets the steel wool 95, and falls downward.

At the same time, operate motor M to rotate fan 6,
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, then passes between wet steel wool 95, and is further blown against the cooling water accumulated on the bottom wall 11, where heat exchange is performed. The cool air is sent to the drip removal chambers 4, 4a, and is sent to the air diffuser 100 from the air inlets 41, 41a. At that time, the cold air containing a large amount of moisture is transferred to the side walls 40, 40a as shown by the arrows.

Note that the cooling water whose water temperature has slightly increased due to heat exchange is drained from the water level adjustment pot 13 to the water tank 201. Then, the refrigerator 202 is connected to the water supply pipe 204.
The water is cooled again to a predetermined temperature, sent into the housing 1, used as cooling water, and circulated in sequence.

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

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

(a) The hot air/cold air generator sprinkles water whose temperature has been adjusted by a water temperature adjustment device from a water sprinkler installed in a heat exchange room, and mixes outside air into the water being sprinkled and the water inside the heat exchange device. The structure is such that cold air or warm air is created by applying heat to the housing and exchanging heat, and then discharges the air from the air outlet to the outside of the housing. Therefore, unlike conventional devices that directly cool or heat outside air to create cold and hot air, this device has good thermal efficiency and can be manufactured at low cost because the refrigerator can be small. Additionally, running costs such as electricity bills can be reduced significantly, and its cooling capacity is comparable to conventional cooling devices.

(b) In structures where heat is exchanged by exposing outside air to water, the air that undergoes heat exchange contains a large amount of moisture. If this air is discharged as it is, there are inconveniences such as causing rust on other attached equipment and discharging water droplets into the house, but in this invention, the moisture in the discharged air is appropriately removed by the drip removal chamber, and water droplets are discharged. It is almost never discharged from the air supply port, and the above-mentioned inconvenience does not occur. Furthermore, unlike conventional devices, the discharged air always contains an appropriate amount of moisture, which is favorable for the growth of crops.

(c) The temperature of the discharged air can be adjusted by adjusting the temperature of water using a water temperature adjustment device.
Therefore, using a temperature sensor or the like, it is possible to control the temperature optimally for plant growth relatively easily.

(d) When generating hot or cold air using groundwater, a well must be dug, and the equipment can only be installed where there is a well. However, the present invention is equipped with a water circulation device and a water temperature adjustment device that adjusts the temperature of the water sent to the water sprinkler, so it can be used even in places where there is no well or underground water.
