Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to an air dehumidifier for producing low-humidity air, for increasing the energy efficiency of the apparatus and for saving the space of the entire apparatus.

2. Description of the Related Art As a conventional device of this type, an evaporator of a refrigerating cycle is arranged in a heat exchanger, and a chamber separated from the evaporator is provided in the heat exchanger, and heat passing through cooling air is provided in the chamber. There is known a type in which an exchange pipe is installed, air to be cooled is caused to flow around the heat exchange pipe, and heat is exchanged between the cooling air and the air to be cooled in a heat exchanger.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the case of such a conventional device, a chamber for exchanging heat between the cooled air and the cooling air is installed in the heat exchanger, or a heat exchange pipe is installed in the chamber. As a result, the heat exchanger itself becomes large, and there are the disadvantages that the number of steps is large and the work takes time when creating the heat exchanger.

Therefore, the present invention has an object to provide an air dehumidifier in which a heat exchanger can be easily manufactured in consideration of the drawbacks of the prior art and the size of the entire apparatus is not increased.

Means for Solving the Problems That is, according to the present invention, an air introduction pipe and an exhaust pipe are connected to a heat exchanger in which a compressor, a condenser, an expansion valve, and an evaporator of a refrigerating cycle that is cyclically connected to an evaporator are installed. In the air dehumidifying device configured to discharge the air introduced through the introduction pipe through the discharge pipe after dehumidifying the refrigerant pipe, the condenser meanders in the cylindrical container and the refrigerant pipe. And a blower fan installed below the exhaust pipe, a part of the periphery of the exhaust pipe is covered with an air introducing pipe, and the double pipe structure is formed on a side plate forming a container of the condenser. This object is achieved by a bonded air dehumidifier.

Action Compressed heated air is blown through the air introduction pipe. Since the air introduction pipe covers the circumference of the discharge pipe on the way, it exchanges heat with the cooling air flowing in the discharge pipe, and the air introduction pipe is pre-cooled by the influence of the ventilation fan installed in the condenser. It

The air precooled via the air introduction pipe is cooled and dehumidified in the heat exchanger in which the evaporator of the refrigeration cycle is arranged, and becomes air having a low absolute humidity and is discharged from the discharge pipe.

The air flowing through the discharge pipe is warmed by heat exchange with the introduced air flowing around it due to the double pipe structure on the way, and is supplied to a predetermined place as air having a lower relative humidity.

Embodiment Hereinafter, the present invention will be described in detail according to an embodiment shown in the drawings.

FIG. 1 is a schematic view showing an embodiment according to the present invention.
Is a heat exchanger in which a compressor 2, a condenser 3, an expansion valve 4, and an evaporator 5 of a refrigerating cycle that is cyclically connected to an evaporator 5 are installed,
A condenser 3 is arranged above the heat exchanger 1.

The condenser 3 includes a refrigerant pipe 7 arranged in a meandering manner in a cylindrical container 6.
And a fan 15 for blowing air arranged below the refrigerant pipe 7, and the container 6 constituting the condenser 3 has the refrigerant pipe 7
A condenser 8 for precooling the compressed air is installed in parallel with the condenser 8 and the condenser 8 is connected to an air introduction pipe 9 that guides the air to the heat exchanger 1.

An air introduction pipe 9 and a discharge pipe 10 for guiding the dehumidified air discharged from the heat exchanger 1 to the outside are installed below the container 6, but a part of the discharge pipe 10 is the introduction pipe 9
Has a double structure, and the double pipe portion is joined to the side plate constituting the container 6.

Specifically, as shown in FIG. 2 to FIG. 4, the double pipe portion is provided with an exhaust pipe 10 communicating with an external means (not shown) and an air outlet of the heat exchanger 1 via adapters 11 and 12. The structure is such that the air introduction pipe 9 having a larger outer diameter than the discharge pipe 10 covers and seals it.
Connection ports 13 and 14 are provided at 11 and 12, the connection port 13 and the air inlet of the heat exchanger 1 are connected, and the connection port 14 and the outlet of the condenser 8 are connected.

Further, this double piping structure is installed so that the air inlet side of the air introducing pipe 9 is higher than the air outlet side thereof, as shown in FIG.

This is so that the water that has been precooled and condensed from the air can flow to the heat exchanger 1 along the air introduction pipe 9.

Further, FIG. 7 shows a second embodiment according to the present invention, in which a double pipe consisting of a discharge pipe 10 and an air introduction pipe 9 is joined to four side plates of a container constituting the condenser 3. It is a thing.

In the air dehumidifying device according to the present embodiment having the above-described configuration, the air supplied from the air compressor or the like once enters the condenser 8 where it is primarily precooled by the ventilation effect of the blower fan.

The air that has been primarily pre-cooled is guided to the air introducing pipe 9, but is cooled by heat exchange with the air flowing in the exhaust pipe 10 because the air introducing pipe 9 and the exhaust pipe 10 have a double piping structure. The secondary cooling is performed by cooling the air around the air introduction pipe 9 by the heat exchange action with the air flowing by the blowing action of the blowing fan.

The secondary-cooled air flows into the heat exchanger 1 through the air inlet of the heat exchanger 1, where it is rapidly cooled (tertiary cooling) by the evaporator 5 of the refrigeration cycle to be dehumidified and has a low absolute humidity. Become.

The dehumidified air exits the air outlet of the heat exchanger 1 and is exhausted through the exhaust pipe 10.

Since a part of the exhaust pipe 10 is covered with the air introduction pipe 9, it is reheated by exchanging heat with the warm air flowing in the air introduction pipe 9.

When moisture in the air flowing through the air introducing pipe 9 is condensed due to heat exchange action, it flows into the heat exchanger 1 due to the height difference in the air introducing pipe 9, and there the drain trap 16 Emitted from.

Further, the heat exchange rate of the second embodiment is higher than that of the first embodiment due to the fact that the double piping structure is connected to the four side plates of the container.

Effects As described above, in the air dehumidifying device according to the present invention, since the precooling chamber is not provided in the heat exchanger and the outer pipe has a double piping structure, the device can be easily manufactured.

Further, since the double piping structure is arranged in the condenser, the device can be downsized.
