Description

Technical Field

[0001] This invention relates to the field of marine engineering temperature control technology, and in particular to a control system and control method for a passenger ship balcony cabin. Background Technology

[0002] With the development of marine technology, large cruise ships are becoming increasingly popular, and the balcony cabins on cruise ships are crucial in ensuring passenger comfort. A cruise ship's balcony cabin consists of a cabin module and a balcony module. The cabin module serves as the main activity and rest area for passengers, while the balcony module provides the main outdoor activity area. Existing large cruise ships use an all-air conditioning system for their balcony cabins, with system control employing a variable air volume (VAV) method. This means that the temperature set by the passengers is achieved by changing the amount of air supplied to and extracted from the room.

[0003] However, the disadvantages of variable air volume (VAV) all-air systems include: First, they lack personalized adjustment capabilities; since the system serves multiple rooms, each room may have passengers who set the preset temperature for the air-conditioned room, causing the VAV system to always be in a state of self-adjustment and balance, and the time required for a single room to reach the preset temperature is relatively long; Second, the minimum air volume of the VAV system is at least 40%-50% of the total required air volume, resulting in unnecessary waste when the room is unoccupied. If the room branch is simply closed, the temperature and odor experience in the enclosed space will be poor when passengers return to the room. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing variable air volume all-air system for passenger ship balcony rooms, which has weak personalized adjustment capability and high operating energy consumption, and to provide a control system and control method for passenger ship balcony rooms.

[0032] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0033] Example 1

[0034] This embodiment provides a control system for a balcony cabin on a passenger ship, such as... Figure 1 As shown, the control system includes: an air volume control module 100 and a fan coil control module 200. The air volume control module 100 includes a data acquisition unit 110 and a first control unit 120. The fan coil control module 200 includes a detection unit 210 and a second control unit 220.

[0035] Data collection unit 110 is used to collect room information and passenger check-in information;

[0036] The first control unit 120 is used to control the target air volume corresponding to the fresh air duct and exhaust air duct of each room based on room information and passenger check-in information.

[0037] The detection unit 210 is used to detect the status information of the balcony door limit switch and the entrance card sensor switch;

[0038] The second control unit 220 is used to control the fan coil unit to enter the economic and energy-saving mode based on the status information.

[0039] The status information includes the balcony door switch information corresponding to the balcony door limit switch and the entrance card insertion information corresponding to the entrance card sensor switch.

[0040] In this embodiment, to more intelligently adjust the temperature and airflow in the rooms, the acquisition unit 110 collects room information including the size of the bathroom and passenger occupancy information including the actual number of passengers. Based on the room information, the fresh air volume corresponding to the fresh air duct is calculated, and based on the passenger occupancy information, the exhaust air volume corresponding to the exhaust duct is calculated. This method enables personalized adjustment of the target airflow for different rooms and different numbers of passengers, allowing the control system to quickly reach the required ambient temperature for passengers. The detection unit 210 determines the open / closed state of the balcony door based on the detected status information of the balcony door limit switch, and determines whether the door card is inserted based on the detected status information of the entrance card sensor switch. When the status information indicates that a passenger has left the room, the second control unit 220, after a set time period, controls the fan coil unit to enter an energy-saving mode, that is, dynamically adjusts the operating speed of the fan coil unit according to the passenger's activity status in the balcony room. This achieves comprehensive energy saving and personalized adjustment from both the target airflow and the fan coil unit's operating mode, improving the passenger's stay experience.

[0041] In one embodiment, the room information includes the bathroom's volume area, and the passenger check-in information includes the actual number of occupants;

[0042] The first control unit 120 is used to calculate the exhaust volume based on the bathroom's volume area and the fresh air volume based on the actual number of occupants, and to determine the target air volume based on the comparison results of the exhaust volume and the fresh air volume.

[0043] In this embodiment, the target air volume is adjusted in a personalized manner based on the comparison between the exhaust volume and the fresh air volume, which improves the accuracy of the personalized adjustment of the target air volume and enhances the passenger experience.

[0044] In one embodiment, such as Figure 2 As shown, the air volume control module 100 also includes a multi-stage constant air volume damper, which is respectively installed on the branch of the fresh air duct and the branch of the exhaust air duct of each occupant room.

[0045] The first control unit 120 is also used to control the opening degree of the multi-stage constant air volume damper based on the comparison result of exhaust volume and fresh air volume to match the target air volume.

[0046] In this embodiment, Figure 2 The schematic diagram shows the application structure of the air conditioning configuration for the balcony cabin of the passenger ship. The balcony cabin includes a fan coil unit 1, a fresh air fan coil unit port 2 (marked 2 in the lower left corner) connected to a multi-stage constant air volume damper, a toilet exhaust fan head 3 and a multi-stage constant air volume damper connection to the exhaust duct (marked 2 in the upper right corner), a bathroom exhaust fan head 3, a return air grille 4 and an air distributor 5. The multi-stage constant air volume damper is connected to the hotel management system.

[0047] Each guest room's fresh air duct and exhaust duct are equipped with a multi-stage constant air volume damper. The damper settings are determined based on the actual number of guests (1, 2, 3, or 4 people). After check-in, the control system automatically adjusts the dampers to match the number of guests. This method improves the automation and flexibility of adjusting the damper based on room occupancy. Furthermore, by using multi-stage constant air volume dampers, the system automatically matches the appropriate airflow during check-in, improving the economic efficiency of the control system.

[0048] In one embodiment, the air volume control module 100 further includes a constant static pressure sensor, which is respectively installed in the main line of the fresh air duct and the main line of the exhaust air duct of each occupant room;

[0049] The acquisition unit 110 is also used to acquire the main duct static pressure corresponding to the main duct of the fresh air duct and the exhaust air duct detected by the constant static pressure sensor;

[0050] The first control unit 120 is also used to keep the static pressure of the main duct corresponding to the multi-level constant air volume damper of multiple levels constant air volume constant pressure ...

[0051] In this embodiment, constant static pressure sensors are installed in the fresh air and exhaust main ducts of the control system. By controlling the variable frequency fan at a certain speed, the target air volume corresponding to the multi-stage constant air volume damper in each room remains constant at different opening degrees. When the static pressure of the main duct remains constant, the air volume corresponding to the multi-stage constant air volume damper at different levels can remain constant, providing a basis for personalized adjustment of the target air volume for different occupant rooms.

[0052] The second control unit 220 is also used to control the fan coil unit to run at the minimum speed after a set period of time when it is determined that there are no people in the room based on the status information.

[0053] In this embodiment, by setting up a balcony door limit switch and an entrance card sensor switch, the control system enters an economic mode when the balcony door is opened or the door is pulled out, thereby improving the economic efficiency of system operation.

[0054] The first control unit 120 is also used to calculate the exhaust volume based on the first set coefficient and the volume area of ​​the bathroom, and to calculate the fresh air volume based on the second set coefficient and the actual number of occupants.

[0055] The first control unit 120 is also used to take the maximum value of the exhaust air volume and the fresh air volume as the target air volume.

[0056] In this embodiment, the first set coefficient is 10 times per hour, the second set coefficient is 28.8 cubic meters per hour, the exhaust volume is equal to the product of the bathroom volume area and 10 times per hour, and the fresh air volume is equal to the product of the actual number of occupants in each room and 28.8 cubic meters per hour. For example, if the pre-set bathroom volume is 6 square meters, and the number of occupants is 1, the fresh air volume is 28.8 cubic meters per hour and the exhaust volume is 60 cubic meters per hour. The maximum value between the fresh air volume and the exhaust volume, 60 cubic meters per hour, is taken as the target air volume. If the number of occupants is 2, the fresh air volume is 57.6 cubic meters per hour and the exhaust volume is 60 cubic meters per hour. The maximum value between the fresh air volume and the exhaust volume, 60 cubic meters per hour, is taken as the target air volume. If the number of occupants is 3, the fresh air volume is 86.4 cubic meters per hour and the exhaust volume is 90 cubic meters per hour. The maximum value between the fresh air volume and the exhaust volume, 90 cubic meters per hour, is taken as the target air volume. The levels of the constant air volume dampers are set according to the different number of occupants.

[0057] In this embodiment, the air volume control module controls the target air volume, and the fan coil control module controls the fan coil unit to enter the economy mode when guests go out, thereby enhancing the personalized adjustment capability of the indoor temperature of the passenger ship's balcony cabin and improving the overall energy-saving effect when passengers go out.

[0058] Example 2

[0059] This embodiment provides a control method for balcony cabins on passenger ships, such as... Figure 3 The aforementioned method, utilizing the control system of the passenger ship balcony cabin in Example 1, includes the following steps:

[0060] S11. Control the target air volume corresponding to the fresh air duct and exhaust duct of each room based on the room information and passenger check-in information collected by the acquisition unit;

[0061] S12. Based on the status information of the balcony door limit switch and the entrance door card sensor switch detected by the detection unit, control the fan coil unit to enter the economic and energy-saving mode.

[0062] In this embodiment, to more intelligently adjust the temperature and airflow in the rooms, information including the size of the bathroom and the actual number of guests is collected. The fresh air volume for the fresh air duct is calculated based on the room information, and the exhaust air volume for the exhaust duct is calculated based on the guest occupancy information. This method enables personalized adjustments to the target airflow for different rooms and different numbers of guests, allowing the control system to quickly reach the required ambient temperature for the guests. The system determines the open / closed state of the balcony door based on the detected status information of the balcony door limit switch and whether the door card is inserted based on the detected status information of the entrance card sensor switch. When it is determined that a guest is out of the room, after a set time period, the fan coil unit is controlled to enter an energy-saving mode. That is, the operating speed of the fan coil unit is dynamically adjusted according to the guest's activity status in the balcony room. This achieves comprehensive energy saving and personalized adjustment from both the target airflow and the fan coil unit's operating mode, improving the guest's stay experience.

[0063] The room information includes the bathroom's floor area, and the passenger check-in information includes the actual number of occupants. Step S11 specifically includes:

[0064] The exhaust volume is calculated based on the bathroom's floor area, the fresh air volume is calculated based on the actual number of occupants, and the target air volume is determined based on the comparison between the exhaust volume and the fresh air volume.

[0065] In this embodiment, a control system for adjusting fresh air and fan coil units is adopted. The temperature control of each passenger balcony room is achieved by adjusting its own fan coil unit. Each set of fan coil units does not affect each other, which significantly improves the ability to personalize the adjustment.

[0066] In this embodiment, room information and passenger check-in information are collected, and the status information of limit switches and sensor switches is detected. The target air volume is controlled, and the fan coil unit enters the economy mode when guests go out, which enhances the ability to personalize the indoor temperature of the passenger ship's balcony room and improves the overall energy-saving effect when passengers go out.
