Description

Technical Field

[0001] The utility model relates to a marine water source heat pump system. Background Art

[0002] The marine water source heat pump system is an efficient and environmentally friendly air conditioning system that uses water as a cold and hot source and achieves cooling and heating functions through heat pump technology. The system is mainly composed of a water source system, a heat pump unit, and a control system. It achieves energy conversion and utilization by utilizing the heat in natural water sources such as groundwater and seawater.

[0003] The working principle of the marine water source heat pump system is mainly based on the principle of thermodynamics. Through the circulation of refrigerant, the heat in the water is extracted and transferred to the space that needs to be heated, or the heat in the space is discharged into the water to achieve the cooling effect. This system has the advantages of high efficiency, energy saving, and environmental protection. It is particularly suitable for relatively closed spaces such as ships and other occasions with high energy demand.

[0004] In ship applications, water source heat pump systems can effectively utilize natural resources such as seawater or river water to provide stable cooling and heating effects for the cabin. At the same time, due to its efficient energy conversion and utilization efficiency, it can also significantly reduce the energy consumption and operating costs of ships.

[0005] 1. The marine water source heat pump system has high requirements on the quality of the water source. If the seawater or river water used contains more impurities or corrosive substances, it may cause corrosion or blockage to the heat exchanger, pipelines and other components of the system, affecting the normal operation and life of the system.

[0006] 2. The ship's water source heat pump system may be affected by the ambient temperature during operation. Under extremely high or low temperature conditions, the cooling or heating effect of the system may be limited to a certain extent, making it difficult to meet the needs of temperature control inside the ship.

[0007] In addition, the installation and maintenance costs of marine water source heat pump systems are relatively high. Due to the limited space and complex working environment of the ship, the installation and maintenance of the system requires professional technicians to operate, and the maintenance cycle is relatively short, which increases the operating costs of the ship.

[0008] 3. Although the energy efficiency of the marine water source heat pump system is relatively high, it may still be difficult to meet the ship's ultimate pursuit of energy efficiency in some cases. For example, under long-term high-load operation, the system's energy efficiency may decline. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Brief descriptions of the content expressed in each drawing in the specification of the utility model are as follows:

[0019] Figure 1 It is a principle block diagram of the marine water source heat pump system. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following is a further detailed description of the specific implementation of the present utility model, including the shapes, structures, mutual positions and connection relationships of various components involved, the functions and working principles of each part, the manufacturing process, the operation and usage methods, etc., with reference to the attached drawings, so as to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present utility model.

[0021] The marine water source heat pump system is customized according to the actual situation and operating environment of the ship, and mainly consists of a water source system, a heat pump unit, a control system, auxiliary equipment, etc. By using natural resources such as seawater or river water, the functions of refrigeration and heating are realized.

[0022] The water source system is used for water intake. A water intake is provided below the ship's waterline. Considering the influencing factors such as ebb tide and ship navigation that the ship may encounter during navigation, the water intake should be set at a suitable position and equipped with a trash rack grille and sterilization and anti-biofouling devices to ensure the cleanliness and quality of the water source. Therefore, the water intake is located below the lowest waterline at the stern of the ship, and the water intake faces the rear side of the ship, so that when the ship is sailing normally, "against the water" suction can also ensure the smoothness and safety of pumping. A trash rack grille is provided outside the water intake to block larger garbage in the water. Before the water source enters the heat pump unit, water treatment equipment such as filters and dirt separators are set to remove impurities and corrosive substances in the water and protect the key components of the system from damage. Therefore, the pipeline structure of the water source system is that the water intake, the water intake pump, the filter, and the filter are connected in sequence through pipelines, and the filters are selected from existing equipment suitable for the treatment requirements of ships.

[0023] The output end of the filter is connected to the heat pump unit. According to factors such as the air-conditioning area, room function, and energy demand of the ship, a suitable model and capacity of the heat pump unit are selected to ensure that the unit can meet the refrigeration and heating requirements of the ship under various operating conditions. If the ship is a sea transport ship, it is necessary to optimize the structure and materials of the heat exchanger to enhance its corrosion resistance and durability.

[0024] The equipment system is equipped with a water storage tank to improve the reliability and continuity of its functions and reduce the energy consumption of the heat pump unit. The heat pump unit has two inputs and two outputs. One of the inputs and outputs is connected to the water storage tank as a circulation interface, and kinetic energy is provided by a circulation pump on this circulation loop. The other input of the heat pump unit is connected to the water source system, and the output is connected to the water supply main pipe. To ensure the stability of the water supply capacity, a booster is provided in the water supply main pipe to maintain the water supply pressure within a set range. The water supply main pipe is connected with multiple branch pipes connecting water-using equipment, and a branch solenoid valve is provided on each of the branch pipes. Regarding whether the water-using equipment has a return water requirement, if there is only output without recovery, there is no need to connect the return water pipeline. If water is needed, the water-using equipment is connected to the water storage tank through the return water pipeline.

[0025] The water storage tank contains hot water. To control the pressure inside the water storage tank, a pressure relief valve is installed on the tank body of the water storage tank. Since some water-using devices have no return water, the hot water in the water storage tank will be consumed. Therefore, it is necessary to monitor the water storage tank. A water level sensor is installed in the water storage tank. The water level sensor is connected and outputs an induction signal to the controller. The entire device is controlled by the controller. The controller is connected to and controls the water source system, heat pump unit, circulation pump, branch solenoid valve, booster pump, and water intake pump to achieve precise control and automatic adjustment of the entire system. By real-time monitoring the operating status and performance data of the system, potential problems can be discovered and solved in a timely manner, improving the stability and reliability of the system.

[0026] The power supply of the entire system adopts a redundant design to improve the reliability of the system. Key components such as the controller and power supply are backed up to ensure that when the main device fails, the backup device can quickly take over and guarantee the continuous operation of the system. The redundant design of the power supply means that there are two input paths for power supply. One is the generator on the ship, and the other is the battery. There are wind energy and / or solar energy power generation devices on the ship deck. The power generation devices are connected and output electrical energy to be stored in the battery. The battery can be used both as a backup power supply and appropriately to reduce the power consumption of the generator. In addition, the controller can also be connected to a wireless communication device to facilitate remote operation and maintenance by the crew or professional technicians.

[0027] During the operation of the system, regular maintenance and servicing are required. The system is regularly cleaned, inspected, and repaired to ensure the stable performance of the water source system, heat pump unit, and auxiliary equipment. Through the implementation of the above design scheme, we believe that this marine water source heat pump system will play an important role in the marine field, providing more efficient and environmentally friendly air conditioning services for the ship, while reducing maintenance costs and improving the overall performance and energy efficiency of the ship.

[0028] This marine water source heat pump system adopts advanced water source heat pump technology and is custom-designed in combination with the actual situation and operating environment of the ship. By utilizing natural resources such as seawater or river water, the functions of refrigeration and heating are achieved.

[0029] The present invention has been described exemplarily above in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
