[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 marine ceiling-mounted split air conditioning unit, including a self-heating channel angle adjustment mechanism, which includes a support frame 11, a mounting ring 12 fixedly connected to the top of the support frame 11, a damper 13 fixedly connected to the top of the mounting ring 12, and a rotating seat 15 fixedly connected to the top of the damper 13; a marine air conditioning outdoor unit, which includes a first mounting box 21, self-heating channels 22 provided on both sides of the first mounting box 21, and an active cooling fan 23 provided on the front of the first mounting box 21; and an air conditioning indoor unit installed on the cabin ceiling, which includes a second mounting box 31, an evaporator 32 provided on the top of the inner wall of the second mounting box 31, and a water receiving tray 33 provided on the inner wall of the second mounting box 31 and directly below the evaporator 32.
[0026] In this embodiment, when the angle of the marine air conditioner's outdoor unit needs to be adjusted for energy saving, it can be operated manually or automatically. For manual adjustment, first loosen the locking knob 18, allowing the rotating disk 16 to rotate freely on the rotating seat 15. The operator rotates the first mounting box 21 according to the wind direction and actual conditions, causing the rotating disk 16 to rotate, thereby adjusting the angle of the self-heating channel 22. After adjusting to the appropriate angle, tighten the locking knob 18 so that one end abuts against the surface of the anti-slip texture 17, thus locking the angle. For automatic adjustment, the self-adjusting motor 19's shaft drives the first mounting box 21 to rotate, thereby adjusting the angle of the self-heating channel 22. During adjustment or ship movement, the damper 13 and spring 14 buffer the impact forces during rotation and movement, preventing damage to the equipment due to vibration.
[0027] Example 2
[0028] like Figure 1-6As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the self-heating channel angle adjustment mechanism further includes a spring 14, which is movably sleeved on the surface of the damper 13. A rotating disk 16 is rotatably connected to the top of the rotating seat 15. The rotating disk 16 is provided with anti-slip texture 17 on the side near the rotating seat 15. A locking knob 18 is threadedly connected to the inside of the rotating seat 15. One end of the locking knob 18 abuts against the surface of the anti-slip texture 17. A self-adjusting motor 19 is fixedly connected to the inner wall of the rotating seat 15. The top of the rotating shaft of the self-adjusting motor 19 is fixedly connected to the bottom of the first mounting box 21. The bottom of the first mounting box 21 is fixedly connected to the top of the rotating disk 16.
[0029] In this embodiment, in the outdoor unit of the marine air conditioner, the compressor 24 compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant, which is then sent to the condenser 25. The active cooling fan 23 operates to accelerate airflow, or utilizes natural wind, to dissipate heat from the condenser 25 through the self-cooling channel 22, cooling the high-temperature, high-pressure gaseous refrigerant into a high-pressure liquid refrigerant. After being throttled and depressurized by the throttling device 26, the high-pressure liquid refrigerant becomes a low-temperature, low-pressure liquid refrigerant, which is then transported to the evaporator 32 of the indoor unit of the air conditioner through a flexible rubber refrigerant hose.
[0030] Example 3
[0031] like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the marine air conditioner outdoor unit further includes a compressor 24, the bottom of the compressor 24 is fixedly connected to the bottom of the inner cavity of the first mounting box 21, a condenser 25 is fixedly connected to the bottom of the inner cavity of the first mounting box 21, a throttle 26 is provided on one side of the condenser 25 and located at the bottom of the inner cavity of the first mounting box 21, the throttle 26, the condenser 25, the compressor 24 and the evaporator 32 are interconnected by a rubber flexible refrigerant pipe, the air conditioner indoor unit further includes an air intake fan 34, the air intake fan 34 is provided on one side of the inner cavity of the second mounting box 31, and a drain pipe 35 is provided on one side of the inner cavity of the water tray 33.
[0032] In this embodiment, indoor air is drawn into the second mounting box 31 by the air intake fan 34 in the indoor unit of the air conditioner. When the air passes through the evaporator 32, it exchanges heat with the low-temperature, low-pressure liquid refrigerant. The heat in the air is absorbed, the temperature decreases, and the air becomes cool air and is returned to the room. During the heat exchange process, water vapor in the air condenses upon cooling and drips into the water collection tray 33, and then is discharged outdoors through the drain pipe 35. This cycle is repeated to achieve cooling and dehumidification of the indoor air.
[0033] The working principle of the ship's ceiling-mounted split air conditioning unit will be explained in detail below.
[0034] like Figure 1-6As shown, when it is necessary to adjust the angle of the marine air conditioner outdoor unit to save energy, it can be operated manually or automatically. For manual adjustment, first loosen the locking knob 18, allowing the rotating disk 16 to rotate freely on the rotating seat 15. The operator rotates the first mounting box 21 according to the wind direction and actual conditions, causing the rotating disk 16 to rotate, thereby adjusting the angle of the self-heating channel 22. After adjusting to the appropriate angle, tighten the locking knob 18 so that one end abuts against the anti-slip texture 17 surface to lock the angle. For automatic adjustment, the self-adjusting motor 19's shaft drives the first mounting box 21 to rotate, thereby adjusting the angle of the self-heating channel 22. During adjustment or ship movement, the damper 13 and spring 14 buffer the impact forces during rotation and movement, preventing equipment damage due to vibration. In the marine air conditioner outdoor unit, the compressor 24 compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant, which is then sent to the condenser 25. The active cooling fan 23 accelerates airflow, or utilizes natural wind, to dissipate heat from the condenser 25 through the self-cooling channel 22, cooling the high-temperature, high-pressure gaseous refrigerant into a high-pressure liquid refrigerant. After being throttled and depressurized by the throttling device 26, the high-pressure liquid refrigerant becomes a low-temperature, low-pressure liquid refrigerant, which is then transported to the evaporator 32 of the indoor unit via a flexible rubber refrigerant hose. Inside the indoor unit, the intake fan 34 draws indoor air into the second mounting box 31. As the air passes through the evaporator 32, it exchanges heat with the low-temperature, low-pressure liquid refrigerant, absorbing heat and lowering its temperature, thus returning the cooled air to the room. During this heat exchange, water vapor in the air condenses upon cooling and drips into the drip tray 33, then is discharged outdoors through the drain pipe 35. This cycle continues, achieving both cooling and dehumidification of the indoor air.
[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.
