[0002] Ships navigate various rivers, where weather conditions are complex and climates are changeable. To provide crew and passengers with a comfortable living and working environment, air conditioning technology can be used to create a suitable artificial climate inside the cabins, thereby improving the environment.

[0003] Currently, the cooling method for marine air conditioners in rivers is mostly based on fan cooling.

If the condenser is not cooled in time, it will affect the cooling effect of the air conditioner. Therefore, a compact integrated marine air conditioning unit is proposed. Utility Model Content

[0012] A further improvement of this utility model is that: a backwash pump is installed inside the water spray pipe, one end of the water spray pipe is connected to the inside of the filter cover, and a one-way valve is installed inside the water spray pipe.

[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] Example 1

[0025] like Figure 1-6 As shown, this utility model provides a compact marine air conditioning unit, including an integrated installation mechanism, which includes an installation box 11. A compressor 12 is fixedly connected to one side of the bottom of the inner cavity of the installation box 11, and a throttle 13 is provided on the other side of the bottom of the inner cavity of the installation box 11. A river water cooling and heat dissipation mechanism includes a sealed box 21, the bottom of which is fixedly connected to the bottom of the inner cavity of the installation box 11, and a condenser 22 is provided inside the sealed box 21. A fresh air intake mechanism includes an insulated box 31, an evaporator 32 is provided inside the insulated box 31, and an air inlet 33 is provided on one side of the inner cavity of the insulated box 31.

[0026] In this embodiment, during the refrigeration cycle, the compressor 12 compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous state, which is then transported to the condenser 22 through the refrigerant pipe. Inside the condenser 22, the high-temperature, high-pressure gaseous refrigerant exchanges heat with the river water in the sealed housing 21 and becomes a high-temperature, high-pressure liquid. It is then throttled and depressurized by the throttling device 13 into a low-temperature, low-pressure liquid refrigerant, which enters the evaporator 32. There, it absorbs heat from the surrounding air and evaporates back into a low-temperature, low-pressure gaseous refrigerant, returning to the compressor 12 to complete the refrigeration cycle.

[0027] Example 2

[0028] like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the liquid outlet of the compressor 12 is connected to the liquid inlet of the condenser 22 through a refrigerant pipe, the liquid inlet of the throttle 13 is connected to the liquid outlet of the condenser 22 through a refrigerant pipe, the liquid outlet of the throttle 13 is connected to the liquid inlet of the evaporator 32 through a refrigerant pipe, the liquid outlet of the evaporator 32 is connected to the liquid inlet of the compressor 12 through a refrigerant pipe, and the river cooling and heat dissipation mechanism also includes a water inlet pipe 23, one end of which is connected to the upper end of the inner cavity of the sealed housing 21.

[0029] In this embodiment, during the river cooling and heat dissipation process, the inlet pump 24 is turned on, and the river water flows into the sealed box 21 through the inlet pipe 23 after filtering impurities through the filter cover 25. After exchanging heat with the condenser 22 and absorbing heat, it is discharged from the outlet pipe 26. At the same time, the water filling branch pipe 27 introduces some water into the pulse anti-clogging water tank 28. The backwash pump 210 is started at regular intervals, and the water in the pulse anti-clogging water tank 28 is flushed back into the filter cover 25 through the spray pipe 29, washing off the impurities on the surface of the filter cover 25. The one-way valve 211 prevents water backflow and realizes the anti-clogging function.

[0030] Example 3

[0031] like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, an inlet pump 24 is provided inside the inlet pipe 23, a filter cover 25 is provided at one end of the inlet pipe 23, an outlet pipe 26 is provided on the side of the inner cavity of the sealed box 21 away from the inlet pipe 23, a water filling branch pipe 27 is provided on the surface of the outlet pipe 26, a pulse anti-blocking water storage tank 28 is provided at one end of the water filling branch pipe 27, a spray pipe 29 is provided on one side of the pulse anti-blocking water storage tank 28, a backwash pump 210 is provided inside the spray pipe 29, one end of the spray pipe 29 is connected to the inside of the filter cover 25, a one-way valve 211 is provided inside the spray pipe 29, the fresh air intake mechanism also includes a fresh air fan 34, the surface of the fresh air fan 34 is fixedly connected to the inner wall of the air inlet 33, and a fresh air outlet pipe 35 is provided on the other side of the inner cavity of the heat insulation box 31.

[0032] In this embodiment, when air is introduced, the fresh air fan 34 is started to allow outside air to enter the insulation box 31 from the air inlet 33. After exchanging heat with the evaporator 32 to regulate the temperature, the air is sent into the ship's interior through the fresh air outlet 35.

[0033] The working principle of this compact marine air conditioning unit will be explained in detail below.

[0034] like Figure 1-6As shown, in the refrigeration cycle, compressor 12 compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous state, which is then transported to condenser 22 through refrigerant pipe. Inside condenser 22, the high-temperature, high-pressure gaseous refrigerant exchanges heat with the river water in sealed enclosure 21, becoming a high-temperature, high-pressure liquid. It then passes through throttling device 13 to reduce its pressure, becoming a low-temperature, low-pressure liquid refrigerant, which enters evaporator 32. There, it absorbs heat from the surrounding air and evaporates back into a low-temperature, low-pressure gaseous refrigerant, returning to compressor 12, thus completing the refrigeration cycle. During the river cooling and heat dissipation stage, inlet pump 24 is activated, and river water flows through inlet pipe 23 after being filtered for impurities by filter cover 25. The water enters the sealed housing 21, exchanges heat with the condenser 22 and absorbs heat, and then is discharged from the outlet pipe 26. At the same time, the water filling branch pipe 27 introduces some water into the pulse anti-clogging water storage tank 28. The backwash pump 210 is started at regular intervals. The water in the pulse anti-clogging water storage tank 28 is flushed back into the filter cover 25 through the spray pipe 29 to wash off the impurities on the surface of the filter cover 25. The one-way valve 211 prevents water backflow and realizes the anti-clogging function. When the air is introduced, the fresh air fan 34 is started to allow the outside air to enter the heat insulation housing 31 from the air inlet 33. After exchanging heat with the evaporator 32 and adjusting the temperature, it is sent into the ship's interior through the fresh air outlet pipe 35.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
