BRIEF DESCRIPTION OF DRAWINGS

[0014] With the description of the embodiments, the specific embodiments of the utility model are further explained in detail, which aims to help the skilled in the art to have more complete, accurate and in-depth understanding of the utility model concept and technical solution of the utility model, and to help its implementation. It should be noted that the "first", "second" and other words in the present application are only convenient for the description of technical solution to distinguish different components, and do not limit the present application. In order to make the technical solution of the utility model more clear, the utility model is explained and described by the following embodiments.

[0015] The embodiment provides a kind of ship cabin temperature control system, as shown in Figure 1 It includes water cooling pipeline, floor heating coil pipe, temperature sensor arranged in each cabin, and also includes controller, heat exchanger, circulating water three-way valve, circulating water pump, cooling equipment. Wherein:

[0016] The controller is electrically connected with the temperature sensor, circulating water three-way valve control end, heat exchanger, circulating water pump and cooling equipment respectively, and the electrical connection includes wired connection and wireless connection.

[0017] The first output end of the circulating water three-way valve is connected to the input end of the circulating water three-way valve through the heat exchanger, circulating water pump, cooling equipment and water cooling pipeline of the cabin to be cooled;The output end of the cooling equipment is also connected to the input end of the cooling equipment through the heat exchanger;The second output end of the circulating water three-way valve is connected to the input end of the circulating water pump through the floor heating coil pipe of the cabin to be heated. They are all connected by pipeline.

[0018] The working principle of the system of the embodiment is as follows:

[0019] Each temperature sensor monitors the cabin temperature in real time and sends it to the controller, which compares the real-time cabin temperature with the preset temperature threshold to automatically determine whether the current cabin needs to adjust the temperature.

[0020] Among them, when the real-time cabin temperature is higher than the preset temperature threshold, the corresponding cabin needs to be cooled;When the real-time cabin temperature is lower than the preset temperature threshold, the corresponding cabin needs to be heated, and since the main engine, generator and fuel boiler and other devices on the ship have working requirements, the cabin with cooling function always exists.

[0021] During cooling, the controller sends control signals to the control terminal of the circulating water three-way valve, the heat exchanger, the circulating water pump, and the cooling equipment to wake up each device and start working. Then, the circulating water pump sends the circulating water to the cooling equipment for cooling to obtain low-temperature circulating water. The low-temperature circulating water is sent to the water cooling pipeline of the cabin to be cooled to cool the cabin, and then sent to the heat exchanger and returned to the cooling equipment to serve as the refrigerant for the heat exchanger.

[0022] After passing through the cooling pipes of the cabin to be cooled, the low-temperature circulating water becomes high-temperature circulating water. At this point, the controller determines whether there is a cabin to be heated. If not, the controller connects the input and first output of the circulating water three-way valve, thereby sending the high-temperature circulating water from the cooling pipes of the cabin to be cooled to the heat exchanger for a certain degree of cooling before sending it to the circulating water pump to start the next cycle. If there is a cabin to be heated, the controller connects the input and second output of the circulating water three-way valve, thereby sending the high-temperature circulating water from the cooling pipes of the cabin to be cooled to the corresponding underfloor heating coil of the cabin to be heated for heating. The circulating water flowing out of the underfloor heating coil of the cabin to be heated is then sent back to the circulating water pump to start the next cycle.

[0023] Compared to traditional technologies, this embodiment incorporates a temperature sensor and a controller. The controller automatically determines whether the cabin temperature needs adjustment based on real-time data collected by the sensor, and sends control signals to the control terminal of the circulating water three-way valve according to different temperature requirements. This allows the three-way valve to activate either the heating or cooling function, resulting in a high level of automation. Furthermore, the heat source for heating in this embodiment is the waste heat generated during cabin cooling, thus effectively utilizing the ship's waste heat and improving energy efficiency.

[0024] Specifically, the controller in this embodiment can be a programmable logic controller (PLC), which has high integration, strong control capabilities, and can take into account the heating and cooling requirements of each cabin.

[0025] A heat exchanger is used to initially cool the circulating water through heat exchange between a refrigerant and the circulating water, reducing the cooling pressure on subsequent cooling equipment and thus improving cooling efficiency. Commonly used heat exchangers include plate heat exchangers. To further improve cooling efficiency, the system in this embodiment also includes a first seawater inlet valve control terminal, which is electrically connected to the controller. The output terminal of the first seawater inlet valve is connected to a seawater discharge outlet through the heat exchanger. Seawater is used as a second refrigerant in the heat exchanger to accelerate its cooling speed. Typically, seawater is used to cool the water for a preset time or until a preset temperature is reached, after which the first seawater inlet valve is closed by the controller, and then the circulating water output from the cooling equipment is used for further cooling. The use of seawater also reduces the ship's energy consumption.

[0026] Similarly, the system of the embodiment also comprises a second seawater inlet valve, a control end of the second seawater inlet valve is electrically connected with the controller and controlled by the controller; and an output end of the second seawater inlet valve is connected to a seawater discharge port through a water cooling pipeline of the cabin to be cooled, so as to improve the cooling efficiency of the cabin to be cooled.

[0027] In the embodiment, the system also adds a filtering device in the circulation path, so that impurities in the cooling circulation are effectively removed, and the stability of the whole system is improved.

[0028] Meanwhile, considering the demand of the crew for autonomously regulating the temperature of the cabin, the system of the embodiment also comprises an HMI screen, the HMI screen is connected with the controller, and the crew can adjust the preset temperature threshold in the controller on the HMI screen in the cabin, so that the controller controls the cabin to be heated or cooled.

[0029] The embodiment also provides a ship, which comprises the ship cabin temperature control system.

[0030] The utility model realizes the effective recycling of waste heat generated in the cooling process, improves the energy utilization efficiency of the ship, and adds a seawater circulation path for recycling heat energy, which improves the cooling efficiency and saves the energy of the ship.

[0031] The above has been described by way of example with reference to the drawings. Obviously, the specific implementation of the utility model is not limited to the above manner. As long as various non-essential improvements are made by adopting the method concept and technical scheme of the utility model, or the above concept and technical scheme of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
