The present invention relates to an air conditioner using a thermoelectric semiconductor, and in particular, it does not use refrigerant gas (CFCs) using mechanical power, but uses the Peltier effect of an environmentally friendly DC power thermoelectric semiconductor to be used for cooling / heating at home or officetel. The present invention relates to an air conditioner using a thermoelectric semiconductor.

The global ozone decay phenomenon caused by the refrigerant gas used in air conditioners is not a local phenomenon but a global phenomenon, and a large amount of refrigerant gas emitted from the northern hemisphere destroys the ozone layer in the stratosphere around the world. When the ozone layer is destroyed, powerful harmful ultraviolet rays do not filter out and reach the surface, which causes skin cancer, cataracts, and weakened immune function, harming human health and ultimately causing climate change to threaten the global ecosystem.

However, conventional air conditioners until now have inevitably used refrigerant gas (CFCs Gas: a factor causing enormous damage to the global ozone layer) having the above problems in the refrigeration cycle. This refrigerant is a liquid that tends to evaporate and the heat exchange process occurs by repeating the change of state from gas to liquid and liquid to gas easily by pressure.

This is called a refrigeration cycle, in which a low temperature is produced by state exchange, while hot heat is also released during compression with a compressor. At this time, since a compressor for applying pressure is generated, a lot of noise and vibration are generated, and these parts must be installed outdoors, which can be a big problem in existing apartments.

First, the refrigerant gas is sucked and compressed from the evaporator to the compressor, and the high temperature and high pressure (˜70 ° C., 15 kg / cm 2) is sent to the condenser. The refrigerant sent to the condenser is forcedly cooled by air cooling to liquefy. At this time, a lot of heat must be discharged to the outside. Liquefied refrigerant enters the receiver dry, removes moisture and dust, and then flows to the expansion valve. In the expansion valve, the high pressure liquid refrigerant expands by adiabatic expansion and becomes a refrigerant in a low temperature low pressure fog state (which may have various values depending on the type of refrigerant) and enters the evaporator again.

The evaporator refrigerant takes heat from the surrounding air through the blower motor and the fan, becomes a gaseous refrigerant from the mist of the refrigerant, and is again sucked into the compressor. In this process, the refrigerant performs a cooling operation while repeatedly circulating the cycle.

By using the CFC-based refrigerant gas to cool the room using the refrigerant as described above, not only the fatal damage to the global ozone layer and the environment, but also the cooling efficiency is low, much energy is wasted. Since the air conditioner is operated only by mechanical driving, failure occurs frequently due to wear or corrosion of parts, and the whole air is heavy, and the refrigerant gas which has a long service life and especially damages the ozone layer and the environment frequently is frequently used. Because of leakage, the replenishment needs to be made periodically, which causes a serious problem of continuously producing refrigerant gas.

The Montreal Protocol decided that:

"In order to restore the global stratospheric ozone layer, it is particularly important for developing countries to achieve the goal of phase-out of CFC-based refrigerant gases. Therefore, developing countries will freeze CFCs refrigerant gas production and consumption to the level of 1999 and by 2005, 50% reduction, 85% reduction in 2007, and production and consumption must be completely discontinued in 2010. Developed countries will stop using and producing CFCs refrigerant gas, except in a few essential areas in 1996. "

As an alternative refrigerant material, the refrigeration / air conditioning cycle of carbon dioxide (CO ₂ ) gas, which is most noticed as a refrigerant material that does not affect the ozone layer, is put to practical use. However, the biggest challenge in this case is how to effectively control the operating operating pressure.

The maximum pressure of the carbon dioxide gas cycle is about 10 MPa (100 atmospheres), which is three to four times the operating pressure of the HFC refrigeration cycle. Because of this, the carbon dioxide gas compressor is also effective for this problem because of its high operating operating pressure itself, the use of heavy and high-strength steel tanks that can withstand this pressure, and the large pressure difference, resulting in frequent global leakage of carbon dioxide gas. The countermeasures will be needed again and cannot be a complete countermeasure.

Therefore, in recent years, there have been several developments of air conditioners using thermoelectric semiconductors. However, since they did not effectively cool the heat of the high temperature portion inevitably emitted from one side of the thermoelectric semiconductor, there was a limit to continuously inducing the low temperature generated on the opposite side.

Therefore, the present invention is to solve the serious problems as described above, by using an environmentally friendly thermoelectric semiconductor, the volume is small and light and the service life is slightly different depending on the type of thermoelectric semiconductor, but when used for 10 hours a day 27 To provide air conditioners using thermoelectric semiconductors that can reduce the air consumption caused by the production of permanent air conditioners that can be used for 50 years and at the same time reduce energy consumption and reduce refrigerant gas production. There is this.

As shown in Figures 1 to 4, the air conditioner using a thermoelectric semiconductor of the present invention is a constant current power supply with a constant DC power supply with a constant nipple (Nipple) and; One end of the heat absorbing power by the power applied from the DC power supply device and the other side generates heat thermoelectric semiconductor 20, the low temperature generating unit 30 is installed on one side of the thermoelectric semiconductor 20 and the heat generation of the thermoelectric semiconductor 20 A thermoelectric cooling unit including a high temperature generating unit 40 installed at the other side to cool the high temperature by the high temperature; A blower 50 installed at one side of the thermoelectric cooling unit; A cooling water tank 60 for supplying cooling water to the high temperature generator 40 by a circulation pump 200; A vaporization heat absorption cooling device including a radiator (70) for cooling the high temperature cooling water stored in the cooling water tank, a radiator cooling fan (80), and a mist generator (38a) for cooling the high temperature cooling water introduced into the radiator; At least one coolant inlet tube 40a through which the coolant flows into the high temperature generating unit from the coolant tank through the circulation pump, and at least one coolant outlet tube 40b through which the coolant warmed from the high temperature generating unit flows out to the radiator. Piping; An insulator exhaust pipe (90) for discharging the hot and humid air generated by the radiator cooling fan (80) to the outside; And a controller 100 connected to the thermoelectric cooling unit to turn on / off an operation.

Around the insulator exhaust pipe 90, the outside air having a relatively lower temperature than the hot and humid air is naturally caused by the flow of hydrodynamic air when the hot and humid air is discharged by the radiator cooling fan 80. The outside air suction port 71 introduced into the air is formed.

The outside air flowing into the outside air inlet 71 has a high humidity and high humidity in the high temperature generating unit 40, the cooling water tank 60, the circulation pump 200, the radiator 70, and the DC power supply unit inside the air conditioner ( 10), since the endothermic heat absorbs when the temperature of the heat generating part such as the controller 100 is lowered, the cooling effect of the low temperature generating part 30 is further maximized.

The controller 100 may include a air volume control switch (not shown) for gradually adjusting the air volume discharged by the rotational speed of the blower 50; A drive switch (not shown) for turning on / off the thermoelectric cooling unit; An operation control switch (not shown) for operating the fog generator 38a; It is composed of a switching switch (not shown) for changing the direction of the current by changing the (+) and (-) polarity of the DC power supply unit 10.

The thermoelectric semiconductor 20 of the thermoelectric cooling part has a property of absorbing heat on one side and emitting heat on the other side, and is formed by sequentially crossing an N-type device and a P-type device.

By the above-mentioned switch, the air conditioner of the present invention can be used to switch between the cold fan and the warm fan.

The low temperature generation unit 30 includes a plurality of heat dissipation plates 31 having a predetermined interval and a heat dissipation fin 32 disposed between the heat dissipation plates; An aluminum concave-convex portion 33 which is installed in contact with one side of the thermoelectric semiconductor 20 to absorb hot heat from heat radiated from the heat dissipation plate 31 and the heat dissipation fin 32 and hot and humid air of outside air; An air inlet 34 through which hot and humid air is blown by the blower 50; An air outlet 35 through which the introduced air is cooled by the heat sink and the heat dissipation fin to be discharged to the outside; And a tube 36 through which the heat sink and the heat dissipation fin are installed, and a low-temperature wind of the bakelite material in which the uneven portion is installed by the connection mount 33a is formed in a rectangular rectangular parallelepiped shape.

As the plurality of heat sinks 32 are formed at a predetermined interval, cold air and hot air are caused to vortex evenly in the intervals and are evenly mixed, and the heat sink and the heat sink fins absorb the temperature as quickly as possible by the aluminum irregularities. It can be.

And the low temperature generating unit 30 and the condensed water outlet 37 for extracting the liquefied condensed water cooled by hitting the heat sink and the radiating fins to the outside; A condensed water tank (38) in which the condensed water is stored; And a condensed water outlet pipe 39 made of copper pipe connected to the condensed water outlet and the condensed water tank and connected to the condensed water outlet through the cooling water tank 60.

The condensed water outlet pipe 39 passing through the cooling water of the cooling water tank 60 is formed in a spiral to act as follows.

That is, due to the low temperature of the thermoelectric semiconductor 20, the condensed water at low temperature (˜4 ° C.) generated and discharged due to condensation of the moisture in the air by condensing the heat sink and the heat dissipation fin is transferred through the condensed water outlet pipe 39. It passes through the cooling water tank 60 in a spiral to cool the cooling water of the high temperature cooling water tank 60 and flows naturally into the condensation water tank 38 without a separate circulation pump due to the installation height difference.

The mist generator 38a controlled by the controller 100 to spray the condensed water into the mist of fine water droplets on the radiator 70 to maximize cooling of the alcohol mixture stored in the cooling water tank 60 is It is provided in the condensation water tank 38.

In addition, the fog generated by the fog generator 38a flows into the fog inlet chamber 300 which is installed in contact with one side of the radiator 70.

The mist discharged by the mist generator into the mist inlet chamber 300 has the following function by the radiator cooling fan 80.

That is, as the cooling water of the cooling water tank 60 supplied by the circulation pump 200 to the high temperature generating unit 40 is cooled by air cooling by the radiator cooling fan 80, the high temperature generating unit continuously. Although there is a limit to lowering the heat of the 40 to the limited cooling water and the radiator cooling fan 80, the condensed water that cools the cooling water of the cooling water tank 60 is formed by the mist generator 38a as a fine mist of water droplets. By discharging to the mist inlet chamber 300 so that the radiator cooling fan 80 is sucked, it is easily vaporized in the radiator 70 to absorb the vaporization heat (539cal / g) to increase the cooling effect.

As such, a large amount of heat of the coolant in the coolant tank 60 is shortened in the radiator 70 by using water-cooled condensed water, air cooled by the radiator cooling fan 80, and vaporization heat absorption method by the mist generator 38a. As it is absorbed in time and flows back into the cooling water tank 60, the cooling effect of the high temperature generator 40 is maximized.

The first embodiment of the high temperature generating unit 40 shown in FIG. 3 is a first cooling unit which is integrally formed in a heat conducting unit 41a (thermal bridge) installed in contact with the other side of the thermoelectric semiconductor 20 and installed inside. Pin 41; A second cooling fin 42 installed in contact with the first cooling fin outside; Five cooling water inflow channels 43 formed opposite to the cooling water inflow pipe 40a for introducing the cooling water to the first cooling fins; And two coolant outflow passages 44 opposed to the coolant outlet pipes 40b for outflowing the coolant.

The heat conduction portion 41a serves as a thermal bridge so that heat from the heat conduction semiconductor 20 is more easily transferred to the first cooling fin 41.

The bakelite tube 36 of the low temperature generating unit 30 serves as a heat insulating material to block external hot air, and at the same time, the low temperature wind generated by the low temperature generating unit 30, ie, cold air, into the room. At the same time serves as a path to send and serves as a frame for coupling the low temperature generating portion 30 and the high temperature generating portion (40).

The low temperature generator 30 and the high temperature generator 40 are integrally fixed by a band clamp (not shown).

The second embodiment of the high temperature generator 40 shown in Figure 4 is formed integrally with the heat conduction portion 41a which is installed in contact with the other side of the thermoelectric conductor 20 and the cooling fin 45 is installed inside ; Three cooling water inflow channels 43 opposed to the cooling water inflow pipes 40a for introducing the cooling water to the cooling fins; And four coolant outflow passages 44 opposed to the coolant outlet pipes 40b for outflowing the coolant.

As shown in FIG. 4, the low temperature generation unit 30 and the high temperature generation unit 40 of the second embodiment generate the high temperature on both sides of the pair of low temperature generation unit 30 and the low temperature generation unit 30 facing each other. It is configured by installing the unit 40.

That is, a pair of low temperature generators 30 are installed in the tube 400 so that the thermoelectric semiconductors 20 are exposed at both sides of the tube 400, and the thermoelectric semiconductors 20 exposed at both sides of the low temperature generator 30. ) Is installed by contacting the high temperature generating unit 40 in the).

Referring to the operation of the air conditioner using the thermoelectric semiconductor 20 according to the present invention configured as described above are as follows.

When the user operates the drive switch of the controller 100 to lower the temperature of the room, the air conditioner of the present invention is operated and the DC power is supplied from the DC power supply unit 10 to the thermoelectric semiconductor 20 so that the thermoelectric semiconductor 20 ) Absorbs the surrounding heat on one side and the absorbed heat on the other side by the DC power supply. The absorbed heat is transferred to the low temperature generator 30, and the released heat is transferred to the high temperature generator 40.

Air generated by the blower 50 installed at one side of the low temperature generating unit 30 is supplied to the air inlet 34 of the low temperature generating unit 30, and the introduced air is a heat sink 31, a heat radiation fin 32 ), The aluminum concave-convex portion 33 is cooled, and the cooled air is discharged to the outside (indoor) through the air outlet (35).

As the air is cooled as described above, the condensed water outlet pipe 39 through the condensed water outlet 37 through which condensed water of low temperature (˜4 ° C.) generated and discharged by condensing and adsorbing moisture in the air hits the heat sink and the heat dissipation fin. Condensed water flows through the cooling water tank 60 while spirally passing through the cooling water tank 60 to transmit the low temperature to the cooling water of the cooling water tank 60, and the mist generator 38a is installed by a difference in installation height without a separate circulation pump. It moves naturally to the tank 38.

Accordingly, the fog generator emits condensed water into the fog inlet chamber 300 as a fog, and the emitted fog is vaporized on the surface of the radiator by the radiator cooling fan 80 to absorb the heat of vaporization (539 cal / g) of the radiator As the temperature drops sharply, the temperature of the cooling water drops.

In addition, the cooling water of the cooling water tank 60 is introduced into the high temperature generating part 40 through the cooling water inlet pipe 40a by the circulation pump 200, and the first and second cooling fins 41 are provided through the heat conducting part 41a. After absorbing the heat transferred to (42), the air flows into the radiator 70 through the coolant outlet pipe 40b, and the air of the coolant is hot and humid by the cooling fan 80 of the radiator 70. And is discharged to the outside (outdoor) through the heat insulating material exhaust pipe 90 is introduced into the coolant tank 60 is circulated again.

As such, the condensed water, the radiator cooling fan 80, and the fog generator 38a effectively and rapidly cool the cooling water of the cooling water tank 60, thereby rapidly cooling the high temperature generation part 40 continuously.

At this time, the outside air inlet 71 formed around the heat insulating material exhaust pipe (90) by the flow of hydrodynamic air relatively low temperature than the high temperature and high humidity air and naturally humid air outside the natural inflow The external humidity is automatically vaporized when the temperature of the heat generating part such as the high temperature generating part 40, the cooling water tank 60, the circulation pump 200, the radiator 70, the DC power supply part 10, and the controller 100 is lowered. To make it more effective.

As shown in the second embodiment of FIG. 4, a pair of low temperature generators 30 are installed in the tube 400 such that the thermoelectric semiconductors 20 are exposed at both sides of the tube 400. It is configured by contacting the high temperature generator 40 to the thermoelectric semiconductor 20 exposed on both sides of the generator 30, the coolant flows into the upper portion of the thermoelectric semiconductor 20 through the three cooling water inflow channel 43 To absorb the heat of the thermoelectric semiconductor 20 primarily through the cooling fins 45, and to absorb the heat through the four cooling water effluent passages 44 around the thermoelectric semiconductor 20. By allowing one coolant to flow out, the cooling effect of the thermoelectric cooling unit can be maximized.

By configuring the low temperature generation unit 30 and the high temperature generation unit 40 in this way, the amount of cooling air discharged per unit time of the low temperature generation unit 30 is increased, thereby further maximizing the cooling effect, and rapidly cooling the indoor air. By discharging to the blower (50) does not give a bunch (no heat generated), there is an advantage that can be used for a long time stably.

As the air conditioner using the thermoelectric semiconductor of the present invention as described above, the air conditioner can be used in small size, light weight, and permanent (more than 27 years), and the efficiency and performance are also improved with the rapid development of semiconductors. It is possible to manufacture air conditioners for home and officetel with incomparably higher efficiency than the method, and can be operated with less energy, and it can be used for cooling / heating only by changing the current direction of the DC power supply unit 10.

Therefore, it is possible to reduce energy consumption, and to use the refrigerant gas harmful to the earth's ozone layer can be expected to minimize the environmental damage, and since the thermoelectric semiconductor can be used permanently, only the thermoelectric semiconductor can be continuously recycled.
