[0002] With the in-depth development of the shipping industry, the functional requirements of modern ship design are increasing. For cruise ships and passenger ships that integrate sightseeing, leisure and entertainment, the environmental protection requirements and passenger comfort index are very high. More service requirements mean that more service systems need to be designed to support the realization of functions, while the ship space is limited, cost control is strict, and the requirements for ship energy consumption levels are constantly increasing. Therefore, it is necessary to continuously innovate and optimize the original design plan. Summary of the invention

[0003] This patent is mainly used for ship refrigeration and heating service systems, which merges the original refrigerant water refrigeration system and boiler water heating system into one system. The refrigeration and heating functions can be achieved simply by opening and closing the valve.

[0004] In order to achieve the above-mentioned purpose, the present invention provides an air conditioning cooling and heating system, which includes a dosing device, an expansion water tank, a medium water circulation pump, a valve, a chiller, and a heat exchange water circulation pump which are sequentially arranged on a water supply pipeline; the connection between the expansion water tank and the medium water circulation pump is connected to the air conditioning user outlet through a pipeline; and the heat exchange water circulation pump is connected to the ocean.

[0005] Furthermore, the chiller is divided into two groups, each group includes an evaporator and a condenser; one end of the evaporator is connected to pipeline II through a pipeline, and the other end is connected to pipeline IV through a pipeline; one end of the condenser is connected to pipeline I through a pipeline, and the other end is connected to pipeline III through a pipeline.

[0006] Furthermore, after pipeline I and pipeline II are connected in parallel, one end is connected to the medium water circulation pump, and the other end is connected to the hot water circulation pump.

[0007] Furthermore, after pipeline III and pipeline IV are connected in parallel, one end is connected to the air-conditioning user inlet, and the other end is connected to the outboard.

[0018] like Figure 1 As shown, an air conditioning cooling and heating system, a dosing device 15, an expansion water tank 14, a medium water circulation pump 13, a valve, a chiller 23, and a hot water circulation pump 18 are sequentially arranged on a water supply pipeline 24; the hot water circulation pump 18 is connected to the ocean 22. The chiller 23 is divided into two groups, each of which includes an evaporator 16 and a condenser 17; one end of the evaporator 16 is connected to the pipeline II2 through a pipeline, and the other end is connected to the pipeline IV4 through a pipeline; one end of the condenser 17 is connected to the pipeline I1 through a pipeline, and the other end is connected to the pipeline III3 through a pipeline. After the pipeline I1 and the pipeline II2 are connected in parallel, one end is connected to the medium water circulation pump 13, and the other end is connected to the hot water circulation pump 18. After the pipeline III3 and the pipeline IV4 are connected in parallel, one end is connected to the air conditioning user inlet 20, and the other end is connected to the outboard 21.

[0019] The medium water flows back from the air conditioner user outlet 19 and is transferred to the chiller 23 through the medium water circulation pump 13. The water exchanger circulation pump 18 draws seawater from the ocean 22 and transfers it to the chiller 23.

[0020] At both ends of pipeline Ⅰ1, valve Ⅳ54 and valve Ⅴ55 are respectively provided on the outside of the pipeline node.

[0021] At both ends of pipeline II 2 and outside the pipeline node, valve III 53 and valve VI 56 are respectively provided.

[0022] At both ends of pipeline III3, valve II52 and valve VII57 are respectively provided on the outside of the pipeline node.

[0023] At both ends of pipeline IV4, valve I51 and valve VIII58 are respectively provided on the outside of the pipeline node.

[0024] Summer cooling operation: open valves Ⅰ51, Ⅲ53, Ⅴ55, and Ⅶ57, and close valves Ⅱ52, Ⅳ54, Ⅵ56, and Ⅷ58. When the medium water passes through the evaporator 16 of the chiller 23, it is evaporated by the refrigerant in the evaporator 16 and cooled by absorbing heat. The cooled medium water is supplied to the air conditioner user inlet 20 for refrigeration. When the hot water passes through the condenser 17 of the refrigerant unit, the heat dissipated by the liquefaction of the refrigerant in the condenser 17 is taken away, and then the seawater that has absorbed the waste heat is discharged overboard 21.

[0025] Winter heating operation: open valve II 52, valve IV 54, valve VI 56, valve VIII 58, and close valve I 51, valve III 53, valve V 55, and valve VII 57. When the medium water passes through the condenser 17 of the chiller, it is liquefied and heated by the refrigerant in the condenser 17, and the heated medium water is supplied to the air conditioner user inlet 20 for heating. When the hot water passes through the evaporator 16 of the refrigerant unit, the refrigerant in the evaporator 16 evaporates and absorbs the heat in the hot water, and then the seawater that has absorbed the heat is discharged overboard 21.

[0026] The beneficial effects of this patent application are as follows:

[0027] a) Save costs.

[0028] The shipyard guides the medium water to the evaporator and condenser respectively through the setting of system pipelines and the opening and closing of valves, so as to achieve cooling in summer and heating in winter. Compared with the traditional scheme, the compressor is used to compress the refrigerant. In summer, the medium water enters the evaporator, and the refrigerant in the evaporator evaporates and absorbs the heat of the medium water to cool the medium water. The cooled medium water is supplied to air-conditioning users for cooling; in winter, the medium water enters the condenser, and the refrigerant in the condenser condenses and releases heat to heat the medium water. The heated medium water is supplied to air-conditioning users for heating. This method is much more efficient than oil boiler heating and electric heating, and consumes less energy.

[0029] b) Save space.

[0030] At the same time, because a set of piping systems is used, cooling and heating are realized respectively by opening and closing the valves. This reduces the pipes, valves, accessories and other materials of a set of piping systems, saves space, and also saves costs.

[0031] This patent application transfers medium water to the evaporator 16 for cooling through the opening and closing of the valve, and then supplies the cooled medium water to the air conditioning user inlet 20 for refrigeration; or transfers it to the condenser 17 for heating, and then supplies the heated medium water to the air conditioning user inlet 20 for heating, without setting up two independent refrigerant water refrigeration systems and boiler water heating systems, which not only saves costs, reduces weight, improves energy utilization efficiency, but also saves precious installation space in the mechanical area and living area. It makes the ship's refrigeration and heating system more simplified and easy to operate, and enhances the comprehensive competitiveness of the ship.

[0032] The above content is a further detailed description of the patent of the present invention in combination with specific preferred implementation methods, and it cannot be determined that the specific implementation of the patent of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the patent of the present invention belongs, they can also make several simple deductions or substitutions without departing from the concept of the patent of the present invention, which should be regarded as falling within the scope of protection of the patent of the present invention.
