Description

Personal air conditioning unit {A personal air-conditioner}

The present invention relates to a heating and cooling device, and more particularly to a personal heating and cooling device that can be used exclusively by the individual by intensively heating and cooling the surrounding space of the user.

In general, the air conditioner is a device for cooling and heating an indoor space such as a residential space, a commercial space, or an office. The construction and operation of such an air conditioner will be described with reference to FIG. 1 of the accompanying drawings.

First, the refrigerant gas compressed at a high temperature and high pressure in the compressor 1 is sent to the condenser 2, and in this condenser 2, the refrigerant gas is condensed by the outside air blown by the blowing fan 3 installed at one side. Condensation occurs as it liquefies as it is released.

At this time, the hot air passing through the condenser 2 is discharged to the outside.

The refrigerant condensed in the condenser 2 in this way is passed through the expansion valve 4 to be reduced to a pressure that is easily condensed and evaporated, and is sent to the evaporator 5. In this evaporator 5, the blower fan 6 installed at one side is provided. The refrigerant liquid absorbs external heat while the refrigerant liquid evaporates by the external air blown by.

Accordingly, the cooling air deprived of heat while passing through the evaporator 5 is discharged into the room to cool the room. The evaporated refrigerant is a low-temperature low-pressure gas that is sent to the compressor 1 to perform the above process. Will repeat.

On the other hand, if you want to heat the room with the air-conditioning device as described above, the refrigerant may be circulated in reverse. In this case, the evaporator 5 acts as a condenser so that warm air flows into the room, and conversely, the condenser 2 ) Acts as an evaporator where cold air is discharged to the outside.

However, since the conventional conventional air conditioning and heating devices are designed to cool or heat the entire indoor space, the air conditioning effect is not transmitted well in an area far from the air conditioning system, and it is impossible to satisfy all the individual tendencies of everyone in the room. Not only that, there was also an inefficient problem of air conditioning required for heating and cooling.

In other words, physiologically, the human breathing rate is 0.133 ℓ / s per person, but the standard air conditioner supplied by general air-conditioning system is 10 ℓ / s per person, and the actual amount required by humans is about 1% of the total air conditioning amount. It is only known.

In addition, the conventional air-conditioning device as described above is bulky and heavy fixed type to be impossible to carry, in particular, a person must move to another place where the air-conditioning system is not installed outside the room where the air-conditioning system is installed. In this case, there was also a problem in that air conditioning could not be expected at all.

Accordingly, the present invention has been made to solve the above problems, the object of the present invention is to provide a personal air-conditioning device that can be used exclusively by the individual by intensively heating and cooling only around the individual is made portable.

As shown in Fig. 2 and Fig. 3, in the air-conditioning apparatus of the present invention, a lower heat exchanger 30 is mounted on a base plate 70 that supports each component of the apparatus on a bottom surface such as a table. A thermoelectric module 10 is attached to the upper part of the heat exchanger 30, and an upper heat exchanger 20 is installed on the upper part of the thermoelectric module 10, and an upper part of the upper heat exchanger 20 is blown therein. A blower case 40 having a fan 44 and a driving motor 43 is mounted, and an upper portion of the blower case 40 has an exhaust duct 50 through which the air blown by the blower fan 44 is discharged. It is a mounted structure.

In addition, a power source 60 for supplying power to the thermoelectric module 10 and the driving motor 43 is installed on the base plate 70.

On the other hand, the thermoelectric module 10 will be described in detail below, but the device is configured to absorb heat from one ceramic plate and to release heat to the other ceramic plate while electrically operating, the upper ceramic plate 11 is the upper Grounded with the heat exchanger 20, the lower ceramic plate 12 is grounded to the lower heat exchanger 30 to transfer heat.

In addition, the upper heat exchanger 20 and the lower heat exchanger 30 are formed such that a plurality of metal plates are arranged upright at regular intervals, which is to increase the heat exchange amount by increasing the contact area with the outside air.

In addition, the blower case 40 mounted on the upper portion of the upper heat exchanger 20 is formed so that the lower portion thereof is opened so that air is introduced through the upper heat exchanger 20, and the upper surface 42 of the center portion is centered. The drive motor 43 and the blowing fan 44 driven by the drive motor 43 is mounted, the air around the upper surface 42 to discharge the air blown by the blowing fan 44 upwards A plurality of holes 42a are formed for this purpose.

In addition, a duct connecting portion 41 is formed above the upper surface 42 of the blowing case 40 to be connected to the inlet of the discharge duct 50, and the duct connecting portion 41 has an upper surface of the blowing case 40. It is formed to converge toward the inlet of the discharge duct 50 to guide the air discharged through the 42 to the inlet of the discharge duct 50 of the upper end.

On the other hand, the discharge duct 50 is a plurality of ducts are connected to the articulated flexible corrugated pipe 51 is to be able to freely change the direction in the desired direction.

In addition, the outlet portion at which the air of the discharge duct 50 is discharged is provided with a flow rate adjusting means 52 that is capable of adjusting the flow rate of the discharged air by adjusting the cross-sectional area of the discharge duct 50, such a flow rate control As the means 52, an apparatus such as an aperture of a camera can be used.

Meanwhile, the thermoelectric module 10 has a heat absorbing part for absorbing heat and a heat dissipating part for dissipating heat absorbed by the heat absorbing part according to the electrode connected thereto. For reference, the operation principle and configuration of the thermoelectric module 10 are determined. And characteristics will be described with reference to FIG. 4.

In general, a thermoelectric module is an electrical component based on a semiconductor material that functions as a solid state heat pump. When a current flows in a coupling part connected in series with two different materials, a thermoelectric module emits or absorbs heat at a contact point of two materials. The Peltier Effect is used, and the thermal energy emitted is proportional to the magnitude of the current.

As shown in FIG. 4, the thermoelectric module 10 used in the cooling and heating apparatus of the present invention using this principle includes an upper ceramic plate 11 formed to be in contact with an object Tc to be absorbed and cooled. The lower ceramic plate 12 formed to contact the object Th for dissipating heat and the p-type semiconductors 14 alternately arranged to connect between the upper ceramic plate 11 and the lower ceramic plate 12. And electrically connecting the n-type semiconductor 15 and the p-type semiconductor 14 and the n-type semiconductor 15 to both ends of the p-type semiconductor 14 and the n-type semiconductor 15. It consists of an electrical cross-connection layer 13 of copper or the like serving as a medium for connecting the plate 11 and the lower ceramic plate 12, the cross-connection layer 13 is connected to a direct current power source (P) The current flows through the p-type semiconductor 14 and the n-type semiconductor 15.

Therefore, when the user applies power to cool or heat the object Tc by using the thermoelectric module 10 configured as described above, the current i is connected to the n-type semiconductor 15 by the cross-connection layer 13. ) And p-type semiconductor 14 alternately flow, whereby electron (-) moves in the direction opposite to the direction of current i in n-type semiconductor 15, while in p-type semiconductor 14 The hole (+) moves in the flow direction of.

That is, the electron (-) and the hole (+) are moved from the upper ceramic plate 11 to the lower ceramic plate 12 through the n-type semiconductor 15 and the p-type semiconductor 14, respectively, and thus Since the ceramic plate 11 absorbs heat and releases it to the lower ceramic plate 12, the upper ceramic plate 11 acts as a heat absorbing portion so that the object Tc in contact with the upper ceramic plate 11 is cooled. The lower ceramic plate 12 acts as a heat dissipation unit so that the object Th in contact with the lower ceramic plate 12 is heated.

In addition, when the polarity of the electricity connected to the thermoelectric module 10 is changed to change the direction of the current, that is, if the parts connected to the positive electrode (+) and the negative electrode (-) of the power supply P are interchanged with each other, the phenomenon described above. On the contrary, heat is released from the lower ceramic plate 12 toward the upper ceramic plate 11 so that the heat absorbing portion and the heat radiating portion are switched, and the magnitude of the heat energy absorbed and radiated can be changed by changing the magnitude of the supplied current. Will be understandable.

On the other hand, the thermoelectric module has the following characteristics.

First, accurate temperature control is possible because the magnitude of heat energy absorbed and dissipated is proportional to the amount of current supplied.

Second, there is no noise and vibration because it does not use mechanical elements that cause movement.

Third, it is compact and light.

Fourth, local air-conditioning is possible.

Fifthly, it is environmentally friendly since no CFC gas or any refrigerant is used.

Sixth, heating and cooling are determined according to the current direction.

Hereinafter, the operation of the cooling device having the above configuration will be described.

If the user wants the cooling operation in the summer, the base plate 70 of the air-conditioning device is seated in the desired place, and then the ceramic plate () of the upper portion of the thermoelectric module 10 acts as a heat absorbing portion and the lower ceramic plate (22) When the power is applied to act as a heat dissipation unit, the thermoelectric module 10 is operated, and the driving motor 43 located on the thermoelectric module 10 is operated to operate the blower fan 44.

Accordingly, the ceramic plate 11 of the upper portion of the thermoelectric module 10 absorbs heat from the upper heat exchanger 20 attached to the ceramic plate 11, the lower portion of the thermoelectric module 10 The ceramic plate 12 discharges the heat absorbed from the ceramic plate 11 of the upper portion to the lower heat exchanger 30. At this time, the upper portion installed on the thermoelectric module 10 by the blower fan 44 As air enters through the heat exchanger 20, the introduced air is absorbed and cooled by the upper heat exchanger 20, and then the cooled air is blown through the blower fan 44 to the upper part of the blower case 40. By discharging the discharge duct 50 through the hole 42a of the surface 42, the surroundings of the user are cooled.

At this time, the discharge duct 50 may be adjusted in a direction desired by the user by the corrugated pipe 51 formed between the ducts, the user by adjusting the flow rate adjusting means 52 formed at the end of the discharge duct 50 The airflow of the desired flow rate can be obtained.

On the other hand, if you want to heat in winter, so that the polarity of the power source connected to the thermoelectric module 10 is switched so that the upper ceramic plate 11 acts as a heat radiating portion and the lower ceramic plate 12 acts as a heat absorbing portion. By doing so, the warmth is discharged through the discharge duct 50.

On the other hand, the present invention is not limited to the above-described embodiment, and various changes and implementations can be made without departing from the gist of the present invention.

For example, in the present invention, the heat released through the ceramic plate 12 of the lower portion of the thermoelectric module 10 is transferred to the lower heat exchanger 30, but the lower heat exchanger 30 is removed and the base plate itself is removed. It may be made of metal and used as a heat exchanger.

As described above, according to the present invention, since a small thermoelectric module that is electrically operated as a cooling and heating means is used, the size of the cooling and heating device can be varied in consideration of the portable and air-conditioning performance, and a user such as a user's desk. It can be installed and used in the desired place, and can only intensively heat and heat the space around the user according to the user's disposition, there is an effect that the user's satisfaction is improved.

In addition, since the present invention uses a thermoelectric module, accurate temperature control is possible, and the discharge duct from which air is discharged can be freely adjusted at a desired angle, and the air flow discharged by using a flow rate adjusting means can be controlled by the user. It can be made, the user can precisely control the cold air or warm air discharged from the air conditioner to the desired state of the air flow.
