BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outdoor unit integrated air conditioner and, more particularly, to an outdoor unit integrated air conditioner that is designed to be compact in an air conditioner and improves cooling efficiency by forming an outdoor unit integrally with an indoor unit.

A general air conditioner is a device for controlling the temperature, humidity, and the like of indoor air in a living space, a commercial space, or an office. The configuration and operation of such an air conditioner will be described with reference to FIG. 1.

First, the refrigerant gas compressed by the high temperature and high pressure in the compressor 1 is sent to the condenser 2, in which the refrigerant gas is blown by the outside air blown by the blower fan 3 for condenser installed on one side. Condensation takes place by releasing heat and liquefying it. At this time, the hot air passing through the condenser 2 is discharged to the outside.

The refrigerant condensed in the condenser 2 as described above is passed through the expansion valve 4 to be reduced to a pressure that is easy to evaporate and is sent to the evaporator 5. In this evaporator 5, an evaporator blower fan installed at one side ( The refrigerant liquid is evaporated by the outside air blown by 6) to absorb the outside heat.

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.

Therefore, the air conditioner installed as described above was separated from the indoor unit and the outdoor unit, and had to be installed through the wall during installation. There were many problems such as lowering the cooling capacity according to the outside temperature.

In addition, since the condensed water is generated in the evaporator inevitably in the process of heat exchange with the indoor air, a hose and an electric pipe for discharging the condensed water to the outside should be installed. These pipes had a significant adverse effect on the aesthetics as well as the space constraints of the pipe installation.

Therefore, in order to solve the above problems, domestic utility model registration application No. 195-28081 "Integrated air conditioner using antifreeze" has been devised.

In other words, this design uses the antifreeze as a coolant to make the cooling coil into a thin tube for easy cooling, and the cooled antifreeze is pumped up to the upper coil (hereinafter referred to as the evaporator) by the pump. The antifreeze bottle can be collected and the antifreeze thus collected can be easily mixed by an impeller.

However, in the case of the air conditioner as described above, there is a problem that the cooling efficiency is lowered because the heat generated from the air conditioner is circulated without cooling.

Therefore, the present inventors use the condensate water generated during the heat exchange in the evaporator as a supplementary water, while cooling the heat generated in the condenser of the air conditioner by using a cooling device in order to solve the above conventional problems, the outdoor unit and the over lake It has led to the development of outdoor air-integrated air conditioners, which can eliminate the need for more compactness.

An object of the present invention is to load a condenser, which serves as an outdoor unit of the air conditioner on one side of the indoor unit, and to cool the loaded condenser by using the coolant formed at the bottom and the shower cooling device installed at the top, the outdoor unit with excellent cooling It is to provide an integrated air conditioner.

Another object of the present invention is to use the condensation water generated during the heat exchange in the evaporator of the air conditioner indoors as supplementary water and cooling water, so that the over-lake can be eliminated to keep the air conditioner clean at all times.

Another object of the present invention is to install a water inlet on the side of the indoor unit main body when the temperature rises in the water tank is detected by the temperature sensor and the water formed in the bottom through the cooling radiator of the compressor through the cooling water introduced through the water inlet By sending it to the tank, the condenser can be as quick as possible.

Hereinafter, with reference to the accompanying drawings the contents of the present invention will be described in detail below.

2 is a view showing the inside of the outdoor air integrated air conditioner according to an embodiment of the present invention, Figure 3 is an enlarged cross-sectional view showing the main portion of the compressor and water jacket of the outdoor air integrated air conditioner according to an embodiment of the present invention.

The configuration of the outdoor unit integrated air conditioner 1 will be briefly described as being divided into a water storage tank 20 and a storage unit 30 by a partition 10 in a main body having a cabinet shape, and a partition in the main body. The condenser 40 is installed.

Between the condenser 40 and the evaporator 2, a pipe 40a for transporting the coolant is connected, and the coolant is circulated through the pipe.

The induction part 50 is installed at a lower inclination angle in the lower part of the evaporator 2 so as to flow the condensation water generated during heat exchange in a predetermined direction.

One end of the induction part 50 is provided with a replenishment tank 60 capable of temporarily storing the condensation water, and the replenishment tank is configured to receive water from the water tank 21 installed above the main body 1. (L1) is provided.

In addition, the lower portion of the replenishment tank 60 is provided with a water jacket 70 for cooling the compressor (3) by flowing water in the replenishment tank.

That is, as shown in FIG. 3, the water jacket 70 is formed to surround the compressor 3, and a plurality of heat dissipation fins 71 are formed to efficiently cool the outside, and the water jacket 70 and A pipe L2 is formed between the replenishment tanks 60, and a valve that is opened and closed by a signal of the water level control device 90 for adjusting the water level in the water storage tank 20 at an intermediate position of the pipe L2. 61 is installed.

In addition, the spray means 80 for spraying cold water to the condenser 40 installed in the receiving portion 30 by pulling up the water in the water storage tank 20 is a water pump 81 is installed in the water storage tank 20 And a pipe 82 for raising the water of the water pump to the drip tray 83 provided at the upper end of the accommodating portion, and a plurality of small holes 83a formed in the drip tray 83.

In addition, the exhaust duct 100 is installed to discharge the hot air generated during the heat exchange in the upper portion of the accommodating part 30, this discharge duct is to be connected to the inside of the indoor unit via the water storage tank (20). By being installed, the heat exiting the discharge duct is lowered by the water in the water storage tank, and the lowered heat is sucked back into the water storage tank by the blower fan 4 installed in the upper portion of the water tank to completely dissipate the heat. do.

In addition, the first and second heat exchange means 200 and 210 are installed in the water storage tank 20 and the accommodating portion 30, respectively. The first heat exchange means serves to cool the water in the water storage tank. In addition, the second heat exchange means 210 installed in the accommodating part is continuously cooled by cold water sprayed finely from the drip tray 80 to temporarily cool the heat of the condenser 40 generated during heat exchange.

The heat exchange means (200, 210) is a radiator having a fine heat dissipation fin or a tube formed of a thin customs pipe is used to form a plurality of layers. Among the heat exchange means, the second heat exchange means is cooled by the auxiliary evaporator 2a installed at one side, and the first heat exchanger 200 is cooled by using water in the auxiliary tank.

Therefore, the refrigerant in the condenser 40 cooled as described above is sent to the evaporator 2 through the tube 40a.

Meanwhile, the condensation water generated in the evaporator 2 during the heat exchange as described above is stored in the replenishment tank 60 through the induction part 50, and the condensed water thus stored is the water surrounding the compressor 3 through the pipe L2. Through the jacket 70 to be sent back to the storage tank 20 it is possible to add a cooling effect.

In addition, the heat generated from the condenser 40 during the heat exchange is first cooled by the second heat exchange means 210, and the heat lowered to some extent is discharged into the indoor unit through the discharge duct 100, the water storage tank ( 20) It will be discharged in a naturally cooled state by the length of water and the pipe in the pipe. At this time, the heat coming out through the discharge duct is introduced into the storage tank by the blower fan (4) again.

By repeating the above steps, it is possible to circulate hot heat in the room with cold air.

According to the present invention, the outdoor air integrated air conditioner can obtain the following effects.

First, by reducing the volume of the outdoor unit, it is possible to achieve compactness by implementing a simple structure.

 Second, by eliminating the existing outdoor unit, it is possible to solve the problem of securing the space, the risk of falling, and the dispute between neighbors.

Third, winter outdoor unit management is not necessary.

Fourth, by eliminating the over-lake to discard the water generated during the heat exchange to the outside, it is possible to always cleanly and hygienically manage the air conditioner surroundings.

Simple modifications and variations of the present invention can be readily used by those skilled in the art, and all such variations or modifications can be considered to be included within the scope of the present invention.
