Description

Portable air conditioner}

The present invention relates to a portable air conditioner, and more specifically, to a portable air conditioner that improves management efficiency by self-processing condensate generated during continuous cooling, and can also be used for heating in winter.

Typically, a portable air conditioner has an indoor unit and an outdoor unit integrated into it and has a structure that can be moved. Because of its convenience, it is widely used at construction sites.

A portable air conditioner according to the prior art is equipped with a compressor, condenser, expansion valve, and evaporator inside the main body, and the main body is equipped with a moving means such as wheels.

Among the components of such portable air conditioners, the evaporator is a device that absorbs heat of vaporization as the refrigerant expands from liquid to gas.

Therefore, the outer wall of the evaporator is cooled, and moisture in the air is condensed due to the temperature difference with the outer wall of the evaporator. Since this condensate is continuously generated, it must be collected and discharged to the outside.

Because portable air conditioners are designed to move freely, they have a drain pipe that collects condensate and discharges it to the outside.

Accordingly, conventional portable air conditioners continuously discharge condensate generated during cooling through pipes exposed to the outside, so when they are used at construction sites, etc., they are not easy to move because the condensate discharged is continuously discharged.

In addition, since a separate water tank must be provided to store the condensate discharged from the pipe, there is an inconvenience in use as the user must periodically dispose of the condensate discharged into the water tank.

In addition, conventional mobile air conditioners are equipped with a water collection tank that collects the condensate. Because condensate is stored in the water collection tank, the weight of the air conditioner itself increases, making it difficult to move. When moving the air conditioner at a construction site, etc., the collected condensate may overflow from the water collection tank or fall to the outside due to the vibration generated during movement. In this case, it may scatter.

Condensate that scatters like this corrodes the chassis and steel parts of the air conditioner, and also causes problems such as electric leakage.

This received condensate is supplied to the second receiving groove 420 of the receiving part along the second recovery flow path 710.

The ultrasonic humidification module 730 installed in the second receiving groove 420 vibrates the condensed water supplied to the second receiving groove 420 to atomize it and supplies it to the downstream of the second heat exchanger 220.

Through this, the heat exchanger in the wind passage, which is used differently from the cooling operation during heating operation, acts as a condenser to supply warm air, and the heat exchanger in contact with the outside air can become an evaporator that recovers heat from the outside air.

Condensation water is generated in the process of recovering heat from outside air, or water is generated during defrost operation. At this time, the present invention can store condensate and send it to an ultrasonic humidification module in front of the condenser during heating operation to achieve humidification.

In other words, when heating operation is performed in winter, condensate is discarded, and in conventional portable air conditioners, if you do not prepare a water tank or connect it to an external pipe to prevent water from leaking out of the device, ice will freeze or the floor will become wet.

The present invention can reduce dryness and prevent condensate from being thrown away by humidifying the generated condensed water or water into the dry air supplied indoors.

In other words, the above configuration is used to recycle condensate from a mobile air conditioner. In the cooling mode, condensate is sprayed at the front of the first heat exchanger to increase the cooling effect, and in the heating mode, the condensate is ultrasonic humidified to increase the heating effect, and the condensate is It provides the effect of improving energy efficiency through recycling.

The present invention can also be used for heating in winter.

cooling mode

In cooling mode, condensate is sprayed at the front of the first heat exchanger, and the condensate is in a liquid state, but when sprayed, it is vaporized to produce a cooling effect. As a result, the temperature of the first heat exchanger is lowered, and when outside air passes through the first heat exchanger, heat is absorbed and cooled air is supplied indoors.

heating mode

In heating mode, the condensate is ultrasonically humidified and atomized. The misted condensate is dispersed in the air and has the effect of increasing the temperature of the air. As a result, the temperature of the second heat exchanger increases, and when outdoor air passes through the second heat exchanger, heat is released and the heated air is supplied indoors.

Condensate recycling

Condensate is a by-product generated during the operation of an air conditioner and is usually discharged through a drain. However, the present invention provides a technology to increase cooling and heating effects and improve energy efficiency by recycling condensate.

Condensate recycling offers the following benefits:

Improved cooling and heating effect: When condensate is recycled and used for cooling or heating, a constant cooling and heating effect can be provided regardless of the temperature of the outside air.

Improved energy efficiency: Condensate recycling can reduce energy consumption because it can provide consistent cooling and heating effects regardless of the temperature of the outside air.

Environmental protection: Recycling condensate reduces the amount of condensate discharged through drains, thereby contributing to environmental protection.

Figures 5 and 6 are diagrams showing examples where the first and second receiving grooves can be opened and closed.

Referring to Figures 5 and 6, the receiving part 400 may be provided with a plate-shaped opening/closing door 450.

A pair of rails 451 are formed on both upper sides of the water tank 410. A slot 421 through which the opening/closing door 450 passes is formed in the partition member 420.

Both sides of the opening/closing door 450 are arranged to be movable along the pair of rails 451.

The opening/closing door 450 is moved along the pair of rails 451 by driving a linear motor 452.

When the cooling mode is selected, the control unit 800 uses the linear motor 452 to move the opening/closing door 450 to seal the second receiving groove 412, and when the heating mode is selected, the control unit 800 moves the opening/closing door 450 to seal the second receiving groove 412. In this case, the linear motor 452 may be used to move the opening/closing door 450 to seal the first receiving groove 411.

Figure 7 is a diagram showing another example of a partition member.

Referring to FIG. 7, an inclined member 422 inclined at a certain angle toward the second blowing fan 320 may be further formed at the top of the partition member 420.

By adding an opening and closing door as described above, recycling of condensate can be performed more efficiently.

In cooling mode, condensate is sprayed at the front of the first heat exchanger. At this time, the opening/closing door seals the second receiving groove to prevent condensate from flowing into the wake of the second heat exchanger. Through this, condensate is sprayed intensively only at the front of the first heat exchanger, helping to increase the cooling effect.

In heating mode, the condensate is ultrasonically humidified and atomized. At this time, the opening/closing door seals the first receiving groove to prevent condensate from flowing into the front end of the first heat exchanger. Through this, the condensate is intensively humidified only in the wake of the second heat exchanger, helping to increase the heating effect.

Additionally, as shown in FIG. 7, adding an inclined member to the partition member allows condensed water to be more efficiently accommodated in the second receiving groove. The inclined member prevents condensate from flowing into the first receiving groove and helps increase the condensate water capacity of the second receiving groove.

Therefore, by adding an open/close door and an inclined member to the above configuration, the recycling efficiency of condensate can be improved.

Figure 8 is a diagram showing an example in which the injector can be rotated.

Referring to FIG. 8, a swivel rotation motor 550 having a rotation shaft 551 capable of swivel rotation may be installed at the other end of the first recovery line 510.

The injector 530 is installed on the rotation shaft 551.

The control unit 800 swivels and rotates the injector 530 using the swivel rotation motor 550 to force condensate flowing along the first recovery line 510 to the front end of the first heat exchanger 210. It can be sprayed in rotation.

By adding the swivel rotation of the sprayer as described above, the spraying effect of condensate can be improved.

In cooling mode, condensate is sprayed at the front of the first heat exchanger. At this time, when the sprayer swivels, condensate is sprayed over a wider area, helping to increase the cooling effect.

Swivel rotation of the injector can provide the following effects:

The cooling effect is improved as condensate is sprayed over a wider area, and the evaporation of condensate is made uniform, thereby maintaining a stable cooling effect. The condensation effect of condensate is improved, and the discharge of condensate can be reduced.

Therefore, by adding the swivel rotation of the sprayer to the above configuration, the spraying effect of condensate can be improved to increase the cooling effect and improve energy efficiency.

Figure 9 is a diagram showing an example in which a temporary storage container is installed at the bottom of a water tank.

Referring to Figure 9, a temporary storage container 900 is disposed at the lower end of the water tank 410 according to the present invention.

The first receiving groove 411 of the water tank 410 is connected to the temporary storage container 900 through a first pipe 910, and a valve 930 is installed in the first pipe 910. The valve 930 opens and closes the first pipe 910 under the control of the control unit 800.

The temporary storage container 900 may be fixed to a bracket (not shown) formed on the main body 100.

The lower end of the temporary storage container 900 is connected to the first receiving groove 411 and the second pipe 920, and a pump 90 is installed in the second pipe 920.

A movement detection sensor 850 is installed in the main body 100 to detect movement of the main body 100.

When movement is detected through the movement detection sensor 850, the control unit 800 opens the valve 930 to allow the condensate contained in the first receiving groove 411 to flow through the first pipe 910. It is discharged into the storage container 900 and stored temporarily.

And if movement is not detected through the movement detection sensor 850, the control unit 800 closes the valve 930 and uses the pump 940 to store the stored inside of the temporary storage container 900. Condensed water is supplied back to the first receiving groove (411) through the second pipe (920).

In addition, a water level sensor 860 is further installed in the first receiving groove 411 to measure the water level of condensate and transmit it to the control unit 800.

The control unit 800 controls the operation of the valve 930 and the pump 940 in real time so that the measured water level reaches a preset reference water level.

Through this, the condensed water contained in the first receiving groove 411 of the water tank 410 flows to the outside of the water tank 400 due to the vibration generated while the main body 100 is moving and scatters into the main body 100. Components installed inside the main body 100 can prevent splashing.

In addition, when the main body 100 is stopped, the first receiving groove 411 can be controlled to accommodate a certain level of condensed water again.

The present invention detects movement of the main body using a movement detection sensor. When the main body moves, the control opens the valve to discharge the condensate into a temporary storage container. This will prevent condensate from leaking while the main body is moving.

The present invention detects movement of the main body using a movement detection sensor. If the main body does not move, the control closes the valve and uses the pump to re-supply condensate. This prevents condensate from being wasted while the main body is not moving.

The present invention measures the level of condensate using a water level sensor. The control unit controls the operation of the valve and pump in real time so that the condensate level reaches the preset standard level. In this way, the discharge and supply of condensate can be efficiently controlled.

That is, in the present invention, by preventing leakage of condensate, damage caused by leakage of condensate to the inside or outside of the building is prevented, waste of condensate is prevented, energy can be saved by recycling condensate, and discharge of condensate is possible. By efficiently controlling oversupply, condensate management becomes easier and leakage or waste of condensate can be prevented.
