Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0029] Figure 1 This is a structural schematic diagram of a marine water source heat pump air conditioning device provided as an embodiment of the present utility model. Figure 1As shown, the device includes: a water supply circuit, a heat recovery circuit, a cooling and heating circuit, a condenser assembly 200, an evaporator assembly 300, and a cooling and heating assembly. The heat recovery circuit is used to recover the waste heat from the operation of the water source heat pump air conditioning unit and to exchange heat with the water supply pipeline on the ship, thereby improving energy utilization. The water supply circuit is used to transport fresh water from lakes and rivers to the water supply pipeline and to exchange heat with the evaporator assembly 300, thereby improving efficiency and environmental protection. The cooling and heating circuit is used to transfer heat through the circulation of refrigerant, thereby enabling the ship's interior to reach a comfortable temperature.

[0030] The condenser assembly 200 and the evaporator assembly 300 are connected in parallel on the piping of the refrigeration and heating circuit, and the condenser assembly 200 and the evaporator assembly 300 are connected in series with the refrigeration and heating assembly on the piping of the refrigeration and heating circuit.

[0031] The first heat exchanger 410 of the heat recovery loop is arranged adjacent to the condenser assembly 200.

[0032] The second heat exchanger 520 of the water supply circuit is arranged adjacent to the evaporator assembly 300.

[0033] The cooling and heating components include a compressor 130, a throttling component 110, and a user component 120. The compressor 130 is connected in series with the condenser component 200 and the evaporator component 300, respectively. The compressor 130, the user component 120, and the throttling component 110 are connected in series.

[0034] Furthermore, the throttling assembly 110 can be an expansion valve.

[0035] Specifically, one end of the condenser assembly 200 and the evaporator assembly 300 connected in parallel is connected to one end of the throttling assembly 110 through a first three-way valve. The other end of the throttling assembly 110 is connected to one end of the user assembly 120. The other end of the user assembly 120 is connected to one end of the compressor 130. The other end of the compressor 130 is connected to the other end of the condenser assembly 200 and the evaporator assembly 300 connected in parallel through a second three-way valve.

[0036] This invention constructs a highly efficient and environmentally friendly marine heat pump system through a water supply circuit, a heat recovery circuit, and a cooling and heating circuit, providing cooling, heating, and hot water for the ship, effectively improving the ship's energy efficiency and environmental performance.

[0037] In one alternative embodiment, the condenser assembly 200 includes at least one condenser and a first control valve; the first control valve is connected in series with the condenser.

[0038] In one alternative embodiment, the evaporator assembly 300 includes at least one evaporator and a second control valve; the second control valve is connected in series with the evaporator.

[0039] like Figure 2 As shown in this application, the condenser assembly 200 includes a first condenser 210, a second condenser 220, a third valve, and a fourth valve. The first condenser 210 and the third valve are connected in series, the second condenser 220 and the fourth valve are connected in series, and the first condenser 210 and the third valve are connected in parallel with the second condenser 220 and the fourth valve on the pipeline of the refrigeration and heating circuit.

[0040] When rapid cooling is required, the third and fourth valves are opened so that the first condenser 210 and the second condenser 220 can work simultaneously to achieve rapid cooling of the room.

[0041] When normal cooling is required, the third or fourth valve is opened to activate the first condenser 210 or the second condenser 220, thereby cooling the room. During normal cooling, if the first condenser 210 is used for cooling, the second condenser 220 serves as a backup for the first condenser 210 to prevent damage to the first condenser 210 from preventing the inability to regulate the indoor temperature.

[0042] The evaporation assembly includes a first evaporator 310, a second evaporator 320, a fifth valve, and a sixth valve. The first evaporator 310 and the fifth valve are connected in series, the second evaporator 320 and the sixth valve are connected in series, and the first evaporator 310 and the fifth valve are connected in parallel with the second evaporator 320 and the sixth valve on the pipeline of the refrigeration and heating circuit.

[0043] When rapid heating is required, the fifth and sixth valves are opened so that the first evaporator 310 and the second evaporator 320 can work simultaneously to achieve rapid heating of the room.

[0044] When normal heating is required, the fifth or sixth valve is opened to enable the first evaporator 310 or the second evaporator 320 to operate, thereby raising the indoor temperature. In normal heating, if the first evaporator 310 is used for heating, the second evaporator 320 serves as a backup for the first evaporator 310 to prevent damage to the first evaporator 310 from preventing the inability to regulate the indoor temperature.

[0045] In one optional embodiment, the water supply circuit includes a heat exchange switching component, a water supply device 510, and a submersible pump 530; the heat exchange switching component and the second heat exchanger 520 are connected in parallel on the water supply circuit pipeline, and the heat exchange switching component, the second heat exchanger 520, the submersible pump 530, and the water supply device 510 are connected in series on the water supply circuit pipeline.

[0046] In one optional embodiment, the heat exchange switching assembly comprises a first valve, a second valve, and a switching pipe; the first valve and the second valve are located at opposite ends of the switching pipe.

[0047] In an alternative embodiment, the water supply circuit further includes a filter assembly 540, which is connected in series with the submersible pump 530.

[0048] Specifically, one end of the filter assembly 540 is connected to a water source, and the other end is connected to one end of a submersible pump 530. The other end of the submersible pump 530 is connected to one end of a second heat exchanger 520 via a first valve. The other end of the second heat exchanger 520 is connected to one end of a water supply device 510 via a second valve. The two ends of the switching pipe are connected to the first valve and the second valve, respectively. By opening the first valve and the second valve, the second heat exchanger 520 can be short-circuited. When it is necessary to cool the indoor temperature, the first valve and the second valve are opened to short-circuit the second heat exchanger 520 and supply water to the water supply device 510 normally. When it is necessary to raise the indoor temperature, the first valve and the second valve are closed to allow the second heat exchanger 520 to exchange heat with the evaporator, thus saving energy.

[0049] In one alternative embodiment, the heat recovery loop includes a circulation pump 420 and marine equipment, with the circulation pump 420, the first heat exchanger 410, and the marine equipment connected in series.

[0050] Specifically, one end of the first heat exchanger 410 is connected to the inlet of the water supply equipment 510, and the other end is connected to one end of the circulating pump 420. One end of the circulating pump 420 is connected to the outlet of the submersible pump 530. The waste heat generated during the operation of the condenser assembly 200 is exchanged with the water source in the pipeline through the first heat exchanger 410, thereby providing the water supply equipment 510 with a higher temperature water source.

[0051] This utility model provides a water source pump air conditioning device for ships, which can regulate the temperature inside the ship as needed. The specific regulation process is as follows:

[0052] like Figure 3 As shown, when it is necessary to cool the indoor temperature, the first and second valves are opened to short-circuit the second heat exchanger 520 and supply water to the water supply equipment 510 normally. The first and second control valves are controlled to connect the condenser assembly 200 with the cooling and heating assembly to form a refrigeration circuit. The refrigerant is compressed by the compressor 130 to obtain a high-temperature and high-pressure gas. The high-temperature and high-pressure gas is released in the condenser assembly 200, condenses into a liquid, and then passes through the expansion valve to reduce pressure and temperature before entering the user assembly 120. At this time, the user assembly 120 acts as an evaporator. In the evaporator, the refrigerant absorbs heat from the surroundings and evaporates into a gas, achieving a cooling effect.

[0053] Furthermore, the first heat exchanger 410 in the heat recovery loop exchanges heat with the condenser assembly 200 to raise the temperature of the water source in the heat recovery loop pipeline, thereby giving the water source of the water supply equipment 510 a certain temperature.

[0054] like Figure 4 As shown, when it is necessary to raise the indoor temperature, the first and second valves are closed to connect the second heat exchanger 520 in series with the water supply equipment 510. The first and second control valves are controlled to connect the evaporator assembly 300 with the cooling and heating assembly to form a heating circuit. Heat exchange occurs between the second heat exchanger 520 and the evaporator assembly 300. If the heat of the evaporator assembly 300 does not reach the preset temperature, the evaporator assembly 300 is heated by a PTC. The evaporator absorbs heat from the surrounding environment, i.e., heat from the water source and / or PTC, causing the refrigerant to vaporize. The compressor 130 compresses the refrigerant, raising its temperature before it enters the user assembly 120. At this time, the user assembly 120 acts as a condenser. The heated refrigerant releases the absorbed heat into the room through the condenser, turning the refrigerant into a liquid. The liquid refrigerant passes through the expansion valve to reduce its pressure and temperature before entering the evaporator, achieving the heating effect.

[0055] This utility model provides a marine water source heat pump air conditioning system, which includes: the marine water source heat pump air conditioning device and controller as described above;

[0056] The controller is used to control the switching component to short-circuit the second heat exchanger in cooling mode; and to control the first control valve to be connected in series with the cooling and heating components.

[0057] In heating mode, the second control valve is connected in series with the cooling and heating components.

[0058] Specifically, when it is necessary to cool the indoor temperature, the controller activates the first and second valves to short-circuit the second heat exchanger and ensure normal water supply to the water supply equipment. The controller also activates the first and second control valves to connect the condenser assembly with the cooling and heating assembly to form a refrigeration circuit. The refrigerant is compressed by the compressor to obtain a high-temperature, high-pressure gas. This gas is released in the condenser assembly, condenses into a liquid, and then passes through the expansion valve to reduce its pressure and temperature before entering the user unit. At this point, the user unit acts as an evaporator. In the evaporator, the refrigerant absorbs heat from the surrounding environment and evaporates into a gaseous state, achieving the cooling effect.

[0059] When indoor temperature needs to be raised, the controller activates the first and second valves to connect the second heat exchanger in series with the water supply equipment. The controller also activates the first and second control valves to connect the evaporator assembly with the heating / cooling components, forming a heating circuit. Heat is exchanged between the second heat exchanger and the evaporator assembly. If the evaporator assembly's heat level does not reach the preset temperature, a PTC (Potentially Transmitted Temperature) is used to raise its temperature. The evaporator absorbs heat from the surrounding environment, specifically from the water source and / or the PTC, causing the refrigerant to vaporize. The compressor then compresses the refrigerant, raising its temperature before it enters the user unit, which acts as a condenser. The heated refrigerant releases the absorbed heat into the room through the condenser, liquefying the refrigerant. The liquid refrigerant then passes through the expansion valve to reduce its pressure and temperature before entering the evaporator, achieving the heating effect.
