Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected" and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art. Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

As shown in fig. 1 to 4, the refrigeration apparatus 100 of the present invention includes a refrigeration indoor unit 1 and a refrigeration outdoor unit 2.

The refrigeration outdoor unit 2 comprises a shell 21, a condenser 22 arranged in the shell 21, a first air opening 23 and a second air opening 24 which are arranged on the shell 21 and positioned at two sides of the condenser 22, a wet curtain 25 arranged at the first air opening 23, a condensate water drain pipe 26 and a fan 27 arranged at the second air opening 24.

The condensed water drain pipe 26 is connected to the refrigerating indoor unit 1 to drain condensed water of the refrigerating indoor unit 1.

The water inlet of the condensed water drain pipe 26 is connected with the refrigeration indoor unit 1 to receive condensed water, and the water outlet of the condensed water drain pipe 26 is located above the wet curtain 25 to discharge the condensed water onto the wet curtain 25.

The condenser 22 is closer to the first air inlet 23 than to the second air inlet 24, and the condenser 22 is used for cooling the high-temperature refrigerant generated by the refrigeration indoor unit 1.

In one embodiment, the wet curtain 25 includes a plurality of wet sheets 251 arranged in parallel in space. Each of the wet sheets 251 has an S-shaped cross-section in the horizontal direction. A plurality of the wet sheets 251 are spaced to form an air inlet 252 and an air outlet 253, and the air outlet 253 is opened toward the condenser 22.

The wet sheet 251 is made of aluminum foil. The surface of the wet sheet 251 is coated with an antiseptic hydrophilic film.

After the condensed water flows on the wet curtain 25, the condensed water can flow downwards along each wet sheet 251 and cover the wet sheet 251 to form a water film. The fan 27 draws air, sucks the air along adjacent two in the clearance between the wet piece 251 and discharges through the fan 27 behind the condenser 22 of flowing through, because the comdenstion water temperature is lower, the air process the water film of wet curtain 25 reduces air temperature by the water film evaporation heat absorption, thereby can improve the cooling effect of condenser 22.

The section of the wet sheet 251 in the horizontal direction is S-shaped, so that the air stroke can be improved, and the cooling effect is improved.

In another embodiment, the wet curtain 25 is formed in a honeycomb plate shape to cover the first tuyere 23. Air enters the housing 21 through the honeycomb holes in the wet curtain 25, passes through the condenser 22 and is discharged from the fan 27.

It was calculated that 1 1.5HP air conditioner, when used in summer, discharged about 2Kg/h, and had a latent heat of evaporation of 2420Kj/Kg, absorbed 1.34KW if the water was completely evaporated within 1 h. And the input power of 1.5HP air conditioner is about 1.1KW, and the refrigerating output is about 3.2KW, then total heat extraction is 4.3 KW. The heat taken away by the evaporation of the condensed water is 1.34KW, the heat taken away by the air is reduced to 2.96 KW. The condensation temperature can be reduced to 40-41 ℃ after the condensation water is added to evaporate and absorb heat according to the air temperature of 30 ℃ and the condensation temperature of 45 ℃ in summer.

Due to the reduction of the condensation temperature, the refrigeration capacity can be improved by about 10 percent, and the energy consumption is reduced by about 7 percent.

The 1-day 1.1-0.07-0.462 KWh can be saved by 6h when 1 1.5HP air conditioner is started in one day. The electricity can be saved by about 41.5 degrees by calculation according to 3 months of starting in summer.

The utility model discloses a refrigerating plant 100 and refrigeration outdoor unit 2 is through setting up wet curtain 25 to the cooling effect that can make full use of the water yield of comdenstion water improves condenser 22 improves refrigeration efficiency and reduces the energy consumption.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
