[0018] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the following embodiments are combined with the drawings to specifically describe the utility model.

[0019] EMBODIMENT

[0020] Figure 1 is a structural schematic view of the utility model, Figure 2 is a structural schematic view of the utility model from another perspective.

[0021] As Figure 1 and Figure 2As shown, the embodiment provides a compression condensing unit for split air conditioner on ship, comprising: a unit outer frame 10, and a circulating water pump 20, a plurality of condensers 30, a plurality of compressors 40 and a connecting pipe (not shown in the figure) which are internally arranged in the unit outer frame 10.

[0022] In the embodiment, the unit outer frame 10 comprises at least a bottom plate 11, four supporting rods 12 arranged at four corners of the bottom plate 11, and a rectangular frame 13 arranged on the four supporting rods 12. The unit outer frame 10 can further comprise two mounting plates 14 for facilitating the installation of the condensers 30, one end of the mounting plate 14 being connected with the bottom plate 11 and the other end being connected with the rectangular frame 13, and the two mounting plates 14 being arranged on two sides of the rectangular frame 13 respectively.

[0023] In the embodiment, the circulating water pump 20 is arranged on the bottom plate 11. The circulating water pump 20 is preferably a seawater pump, so that the utility model can be applied to various types of ships, and the compression condensing unit is smaller and more convenient to install.

[0024] In the embodiment, the condensers 30 are arranged above the circulating water pump 20, and the condensers 30 are connected with the circulating water pump 20 through the connecting pipe. The condensers 30 are preferably double-pipe condensers.

[0025] In the embodiment, each condenser 30 has four connecting ports, two of which are connected with the circulating water pump 20 through the connecting pipe, one of which is connected with a compressor 40 through the connecting pipe, and one of which is connected with a throttling expansion valve in the split air conditioning system through the connecting pipe and then connected with an evaporator.

[0026] In the embodiment, the plurality of compressors 40 are arranged on the bottom plate 11 and below the condensers 30, and each compressor 40 is connected with a condenser 30 through the connecting pipe. The compressors 40 are preferably direct-current brushless variable frequency compressors. The starting current of the compressors 40 is 0, and the capacity reservation is not less than 20%, so that the utility model meets the new energy development concept.

[0027] In the embodiment, the compressors 40 are also connected with the evaporators in the split air conditioning system.
