However, the composition of the chiller circulation system 20 belongs to the prior art (Prior Art), and is not a patent of the present invention.

The main feature of the present invention is that the evaporator 60 is disposed in a duct 70. The duct 70 has an air inlet 71 connected to the air outlet 81 of the axial fan 80, and the axial flow The air blower 80 is provided with an air suction pipe 82 extending to the surface of the vertical casing 10 for sucking outside air (A), and a surface of the vertical casing 10 is provided with a filtering unit 83 on the suction pipe 82. The filter unit 83 may be composed of a filter screen, activated carbon, a photocatalyst, etc., but the filter unit 83 is a prior art (Prior Art), and is not a patent of the present invention, and the wind is not described again; The tube 70 is opposite to the other end of the air inlet 71 to form a cold air outlet 72 for Send out air-conditioning (C). In addition, at least one cold water outflow port 73 is provided at the bottom of the air duct 70, so that the water liquid (L) formed around the outer side of the evaporator 60 is dripped from the cold water outflow port 73 to help the condenser 40 to dissipate heat.

In this embodiment, the chiller circulation system 20 includes two or more, and each of the chiller circulation systems 20 includes a DC compressor 30, a condenser 40, an expansion valve 50, and an evaporator 60. And the air duct 70, and the vertical casing 10 is provided with a corresponding through hole 16 for the cold air outlet 72 of each of the air ducts 70 to send cold air; as shown in FIG. 3, two cold machine circulation systems 20 Each of the evaporators 60 and the air ducts 70 are arranged in an up-down manner, and the DC compressors 30 and the condensers 40 are arranged in a side-by-side configuration, thereby achieving a thinning and having a cold air outlet 72 both above and below, and lifting the cold air blowing. effectiveness. Furthermore, the cold cycle system 20 is controlled by a control panel 12 provided on the surface of the vertical cabinet 10, respectively.

As for the cold water outflow port 73, in the present embodiment, a plurality of holes are provided at the bottom of the air duct 70 to allow the cold water to drip in a natural falling manner of gravity, and of course, the cold water can be guided to the water by the water conduit 74. A fan 44 disposed above the condenser 40 uses the centrifugal force of the fan 44 to pry the dripped liquid (L) into a water mist to the condenser 40 to help the condenser 40 dissipate heat. Therefore, the fan 44 must be disposed above the condenser 40, and the cooling water mist is blown to the condenser 40 to help dissipate heat, which is different from the conventional air-conditioning system by using a fan to extract the heat dissipated by the condenser. It can be implemented indoors. If the heat extraction method is used, the heat extracted from the vertical casing 10 will remain in the room, which will cause the lack of cold air strength.

In this embodiment, the bottom of the vertical casing 10 forms a base shell 101 of a larger width, so that the vertical casing 10 presents an L-shaped body, and the base casing 101 is provided with a circulation outlet 14 A rear side of the vertical casing 10 is provided with a circulation inlet 15 above the circulation outlet 14, so that the gas inside the vertical casing 10 is sent out by the circulation outlet 14 and exchanged with the outside air, and then the circulation inlet is used. 14 enters the vertical casing 10, in the embodiment, the wind The fan 44 is disposed above the condenser 40, and the lower portion of the condenser 40 further includes a duct 45 connected to the circulation outlet 14 for guiding the internal gas to the circulation outlet 14. Therefore, the present invention utilizes the fan 44 to blow cold water mist to the condenser 40 to help it dissipate heat, and allows the air to be cyclically exchanged; accordingly, the vertical thin type DC air conditioner 90 of the present invention can be used for indoor use.

As shown in FIG. 4 to FIG. 6 , in the present embodiment, the evaporator 60 is a U-shaped body, and the air duct 70 is shaped as a U-shaped body in accordance with the shape of the evaporator 60 . That is, the refrigerant delivery line 63 and the fins 64 constituting the evaporator 60 are formed into a U-shaped body, so that the effective length of the cold air can be made in the chamber 11 of the limited space of the vertical cabinet 10. Increase to achieve the required cold air intensity. In this embodiment, the axial flow fan 80 includes a housing 84, a fan blade 85, and a motor 86. However, the prior art is not described herein.

The condenser 40 is disposed below the evaporator 60, and a liquid-water receiving tray 43 is disposed at the bottom thereof; the vertical casing 10 is provided with a cooling air supply for the cold air outlet 72 of the air duct 70. (C) The through hole 16 that is sent out. However, whether in the natural falling manner of the gravity or the water conduit 74, the water (L) which has not been evaporated through the condenser 40 finally falls into the receiving tray 43, as shown in FIG.

In the present embodiment, as shown in FIG. 7, the DC compressor 30 is housed in a sealed outer casing 30A, and only the ends of the refrigerant suction port 31 and the refrigerant discharge port 32 extend to the sealed outer casing 30A. The inside of the sealed outer casing 30A is filled with a liquid 33 and a water absorbing buffer 34, thereby forming a sealed type direct current compressor, and the liquid 33 includes: any one of cooling liquid, oil or water or a combination thereof. The water absorbing buffer 34 comprises: any one of sponge, cloth or fiber or a combination thereof. This reduces noise and makes it more suitable for indoor air conditioning designs. As for the internal constitution of the DC compressor 30, the patents of the present invention are not described herein. The currently available DC compressor 30 has a length of about 12 cm, and the compression capacity of the compression chamber is 2.0 cc. The speed of 2000 RPM or more (but not more than 6500 RPM) can obtain an output of about 460 watts/1567 Btuh. Therefore, with the cold air capacity of the DC compressor 30, the ingenious configuration of the front evaporator 60 is disposed in a duct 70, so that the The thickness (T1) of the vertical casing 10 is about 30 cm, and the thickness (T2) of the base casing 101 is about 45 cm, and the height (H) is about 168 cm. The small volume can also achieve the effect of the required cold air strength. As shown in Fig. 8, when the present invention is close to the wall surface (W), the base shell 101 is also only 45 cm away from the wall surface (W), so it does not occupy too much space, and the vertical cabinet 10 and the wall surface ( The 15 cm interval (S) of W) is just as a space for drawing outside air (A) and circulating exchange.

By means of the above-mentioned technical means, the vertical thin type DC air conditioner 90 of the present invention has the cold air (C) generated by the evaporator 60 in the air duct being effectively blown out, so that the small-volume cold machine circulation system 20 has sufficient coldness and utilizes The water (L) of the evaporator 60 helps the condenser 40 to dissipate heat so that there is no high temperature around the casing 10, and it has an effect that it can be used indoors and is easy to move.

In addition, in the present invention, the cold circulatory system 20 is described as an embodiment, but it is necessary to know that the setting of the control panel 12 is used to control the circulation direction of the chiller circulation system 20, and the present invention can also be used as a heating machine. Or the dehumidifier is used, but these compositions are prior art (Prior Art), and are not described here.

To sum up, the technical means disclosed in the present invention have the invention patents such as "novelty", "progressiveness" and "available for industrial use", and pray for the patent to be invented by the bureau. German sense.

The drawings and the descriptions of the present invention are merely preferred embodiments of the present invention, and those skilled in the art, which are subject to the spirit of the present invention, should be included in the scope of the patent application.
