Description

Technical Field

[0001] The invention relates to a ship environment control system and method, belonging to the technical field of ship auxiliary machinery. Background Art

[0002] The ship's environmental control system is an important auxiliary system for maintaining specific environmental parameters of the cabin atmosphere. It is widely used in ships and marine engineering platforms such as crane ships, dredgers, semi-submersible ships, scientific research ships, transport ships, passenger and vehicle ships, and seawater drilling platforms. The main working principle of the ship's environmental control system is to filter, cool, dehumidify, humidify, heat, and pressurize the outside atmosphere and cabin air through centralized or distributed air handling equipment, and then send the treated air into each ship's cabin through air ducts and terminal equipment. The main function of the ship's environmental control system is to maintain the set temperature and humidity of the ship's cabin to improve the crew's working and living conditions and improve the crew's work efficiency.

[0003] The traditional ship environmental control system has the following defects:

[0004] First, the traditional ship environmental control system lacks natural, clean, and pollution-free odor generation devices. Although the traditional ship environmental control system can simulate different odors through certain medicinal materials, essential oils, aromatherapy, and spices with specific odor molecules, the production, processing, transportation, and storage of the above-mentioned specific odor molecules often require the addition of artificial synthetic substances, or physical and chemical treatment, causing certain environmental air pollution. In addition, the above-mentioned specific odor molecules are often accompanied by secondary environmental pollutants during the process of simulating the generation of odors, which is not conducive to the health of the crew.

[0005] Secondly, the traditional ship environmental control system lacks effective and efficient treatment of pollutants, carbon dioxide, foul odors and peculiar smells in the air, resulting in the persistence of existing odors and peculiar smells in the ship's cabins and the inability to effectively remove them. These odors and peculiar smells are likely to leak through the ventilation and air-conditioning system and spread to other places. There is also a risk of odor superposition and cross-flavoring with the environmental control system, thereby producing unpleasant and uncomfortable gas odors, which does not meet the comfort of the crew.

[0006] Third, the traditional ship environmental control system lacks effective odor regulation control means and control strategies. Although the traditional ship environmental control system can detect certain specific odor molecules (such as hydrogen sulfide, ammonia, methane, ozone, etc.) through odor sensors, it is difficult to effectively detect and remove odors with relatively complex components in the air (such as foot odor, sweat odor, body odor, feces odor, stench, etc.), and lacks odor regulation control strategies and control capabilities, making it difficult to meet the higher level of crew olfactory sensory comfort and mental pleasure requirements. Summary of the invention

[0018] Preferably, the exhaust duct is provided with a ninth air volume regulating valve for adjusting the air volume discharged from the cabin into the atmosphere.

[0019] Another aspect of the present invention is to disclose a ship environment control system method, which adopts the above-mentioned ship environment control system and is characterized by comprising the following steps:

[0020] Step 1: Turn on the ship's environmental control system and enter the self-test mode;

[0021] In the self-check mode, the control unit automatically detects the fault of the ship's environmental control system. If the ship's environmental control system fails, it will enter the fault mode. In this mode, the crew needs to perform manual operation.

[0022] Step 2: If the ship's environmental control system has no fault or the fault mode is released, it will enter the standby operation mode;

[0023] In the standby operation mode, the control unit waits for the crew to input and confirm the operation signal parameters. Preferably, the operation signal parameters include: set air volume, set pressure, set temperature, set humidity, set carbon dioxide concentration, set pollutant concentration, set odor concentration, set seasoning scheme;

[0024] Step 3: If the ship's environmental control system receives the operation signal confirmation, it ends the standby operation mode and enters the default operation mode. In the default operation mode, the ship's environmental control system uses the following steps to process the air: odor removal, mixing, filtering, heat exchange, humidification, and pressurization. Among them: the air volume regulating valves of the second fresh air duct, return air duct, exhaust air duct and the fourth air supply duct are opened, the fifth, sixth, seventh and eighth air volume regulating valves are closed, and the first air volume regulating valve is closed. Except for the fresh air odor removal unit, return air odor removal unit, the first, second, third and fourth odor regulating units, other units operate according to the received confirmation operation signal, and the ship environmental control system collects various parameter indicators: if the odor parameter detected by the second comprehensive sensor exceeds the set value, the fresh air odor removal unit is opened, the first air volume regulating valve is opened, and the second air duct air volume regulating valve is closed; if the odor parameter detected by the first comprehensive sensor does not exceed the set value, the fresh air duct odor removal unit is closed, the first air volume regulating valve is closed, and the second air volume regulating valve is opened; if the odor concentration parameter detected by the third comprehensive sensor exceeds the set value, the return air odor removal unit is opened, and if the odor concentration parameter detected by the third comprehensive sensor is lower than the set value, the return air odor removal unit is closed. When the default operation mode lasts for a certain time interval, the default operation mode ends.

[0025] Step 4: If the ship's environmental control system ends the default operation mode, it enters the seasoning operation mode. In the seasoning operation mode, the ship's environmental control system uses the following steps to treat the air: odor removal, mixing, filtration, heat exchange, humidification, pressurization, and odor adjustment. Furthermore, the seasoning operation mode is divided into scheme one, scheme two, and scheme three seasoning schemes, and any scheme can be selected for adjustment. Among them:

[0026] Option 1: Adjust the smell according to the set time period.

[0027] Specifically, when the time in the ship's environmental control system is in a certain time period, one or several channels in the odor adjustment unit are opened or closed in a regular combination, and the corresponding air volume control valve is opened or closed regularly to achieve a certain odor adjustment or several mixed combination odor adjustments. When the time in the ship's environmental control system is in a time period other than the above, or the crew manually turns off the odor adjustment function, the fourth air volume control valve is opened, and the odor adjustment unit and the air volume control valve are closed.

[0028] Option 2: Adjust according to the set odor parameters.

[0029] Specifically, the first odor adjustment unit and the fifth air volume adjustment valve are opened. When the duration is a certain time, if it is detected that the fourth comprehensive sensor parameter is lower than the first set odor value, the second odor adjustment unit is opened and the sixth air volume adjustment valve is opened. When the duration reaches a certain time, if it is detected that the fourth comprehensive sensor parameter is lower than the first set odor value, the third odor adjustment unit is opened and the seventh air volume adjustment valve is opened. When the duration reaches a certain time, if it is detected that the fourth comprehensive sensor parameter is lower than the first set odor value, the fourth odor adjustment unit is opened and the eighth air volume adjustment valve is opened. When the duration reaches a certain time, the odor parameter of the air supply integrated pipeline is detected again. If it is detected that the fourth comprehensive sensor parameter exceeds the first set odor value, the duration reaches a certain time, then the fourth, third, second, and first odor adjustment units are closed in sequence, and the air volume adjustment valves of the corresponding air supply branches are closed at the same time until the set odor parameter is reached.

[0030] Option three, make adjustments based on the set olfactory sensory comprehensive evaluation indicators.

[0031] Specifically, the olfactory sensory comprehensive evaluation index is divided into comfort, general comfort, and discomfort. The olfactory sensory comprehensive evaluation index is obtained through standardized testing and statistics according to the odor type, odor fragrance, odor intensity, crew gender, crew age, crew position, and time. The control unit obtains the crew gender and crew age in the ship personnel information management system, takes gender as the first priority, age as the second priority, and crew position as the third priority, and automatically matches the existing or closest olfactory sensory comprehensive evaluation index in the database to be divided into a comfort model and sorts it. Further, the comfort model is a function fitting relationship between the odor type, odor intensity, and odor fragrance with respect to the release time, and the specific expression is that in a specific time period, the odor type air with a specific odor intensity and odor fragrance is released to the crew cabin. The above mathematical model is input into the system, and the model is sorted in priority order to realize intelligent adjustment of the first, second, third, and fourth odor adjustment units and the fourth, fifth, sixth, seventh, and eighth air volume control valves to release specific odor gases according to a specific release amount in a specific time period to meet the crew's olfactory sensory comfort and mental pleasure requirements.

[0032] The advantages of the present invention are:

[0033] (1) The ship environmental control system of the present invention utilizes the unique photosynthesis of plants as an air odor regulating device, and can produce natural, clean, oxygen-rich, pollution-free, and specific odor air gas.

[0034] (2) The ship environmental control system of the present invention utilizes the unique purification effect of matter as an air odor removal device, which can reduce the concentration of air pollutants, carbon dioxide and odor without generating secondary pollutants.

[0035] (3) The ship environmental control system of the present invention provides specific odor gas air for different cabin units and different crew members through air odor adjustment and odor removal devices, as well as efficient odor adjustment control means and control strategies, to meet the crew members' requirements for olfactory sensory comfort and mental pleasure.

[0051] The exhaust pipe EA is connected to the cabin 9 and the outside atmosphere. The exhaust pipe EA is provided with a ninth air volume regulating valve 10-9 for regulating the air volume discharged from the cabin into the atmosphere.

[0052] The ship environment control system is controlled by a control unit 1, which uses a PLC programmable logic controller to automatically control the operation, collect and monitor various system data in real time, and perform human-computer interaction.

[0053] Based on the above-mentioned ship environmental control system, the process of adjusting and controlling different functions is realized, which mainly includes the following steps:

[0054] Step 1: Turn on the ship's environmental control system and the system enters self-test mode M1.

[0055] In the self-check mode M1, the control unit 1 of the ship's environmental control system automatically detects faults in the ship's environmental control system. If a system fault occurs, such as a fault in the filter unit 4 or a fault in the air supply unit 7, the system automatically switches and enters the fault mode M0, in which manual operation is required by the crew.

[0056] Step 2: If the ship environmental control system does not enter the fault mode M0, or the fault mode M0 is released, the system enters the standby operation mode M2.

[0057] In the standby operation mode M2, the control unit 1 waits for the crew to input and confirm the operation signal parameters. In the embodiment of the present invention, a preferred implementation is to set the upper limit of the carbon dioxide concentration of the first integrated sensor 11-1 and the second integrated sensor 11-2 to 200ppm and the upper limit of the TVOCs concentration to 0.3mg / m 3 The upper limit of the carbon dioxide concentration of the third integrated sensor 11-3 is set to 1000ppm and the upper limit of the TVOCs concentration is set to 1.0mg / m 3 The upper limit of the carbon dioxide concentration of the fourth integrated sensor 11-4 is set to 500ppm and the upper limit of the TVOCs concentration is set to 0.5mg / m 3 , air supply volume is 300m 3 / h, the external residual pressure of the blower is 400Pa, the air supply temperature is 20℃, and the air supply humidity is 60%.

If the odor concentration parameter detected by the second integrated sensor 11-2 exceeds the set value (carbon dioxide concentration 200ppm, TVOCs concentration 0.3mg / m 3 ), the fresh air odor removal unit 2-1 is turned on, the first air volume regulating valve 10-1 is turned on, and the second air duct air volume regulating valve 10-2 is closed. If the odor parameter detected by the first integrated sensor 11-1 does not exceed the set value (carbon dioxide concentration 200ppm, TVOCs concentration 0.3mg / m 3 ), the fresh air duct odor removal unit 2-1 is closed, the first air volume regulating valve 10-1 is closed, and the second air volume regulating valve 10-2 is opened. If the odor concentration parameter detected by the third integrated sensor 11-3 exceeds the set value (carbon dioxide concentration 1000ppm, TVOCs concentration 1.0mg / m 3), the return air odor removal unit 2-2 is turned on, and if the odor concentration parameter detected by the third integrated sensor 11-3 is lower than the set value, the return air odor removal unit 2-2 is turned off. When the default operation mode M3 operation duration reaches t=30min, the default operation mode M3 is terminated.

[0060] Step 4: If the ship environmental control system ends the default operation mode M3, it enters the seasoning operation mode MT. In the embodiment of the present invention, the air treatment process of the seasoning operation mode MT is: odor removal, mixing, filtering, heat exchange, humidification, pressurization, and odor adjustment.

[0068] Specifically, the control system 1 of the ship's environmental control system obtains the crew gender, crew age, and crew position parameters in a cabin unit in the ship's personnel information management system, with gender (male, female) as the first priority, age (0-17 years old, 18-30 years old, 31-40 years old, 41-60 years old, 61-90 years old) as the second priority level, and crew position (captain, first mate, second mate, chief engineer, second engineer, medical technician, scientist, senior VIP crew member, VIP crew member, ordinary crew member) as the third priority, and automatically matches the existing or closest olfactory sensory comprehensive evaluation indicators in the database into comfort models and sorts them.

[0069] In the embodiment of the present invention, a more preferred implementation is that the olfactory sensory comprehensive evaluation index model can be recorded and output in a table in the following template format.

[0070]

[0071]

[0072] Furthermore, the comfort model is a mathematical model of fitting functions of odor type, odor intensity, and odor fragrance with respect to release time. Specifically, in a specific time period, odor type air with specific odor intensity and odor fragrance is released into the crew cabin to adjust the air with different odors.

[0073] The above mathematical model is input into the ship environmental control system, and the model is sorted in priority order according to the official comprehensive evaluation index model of different crew genders, crew ages, and crew positions. First, model 1 is input into the ship environmental control system. According to the control of control unit 1, the first odor adjustment unit 8-1, the second odor adjustment unit 8-2, the third odor adjustment unit 8-3, and the fourth odor adjustment unit 8-4 are adjusted, and the fourth air volume control valve 10-4, the fifth air volume control valve 10-5, the sixth air volume control valve 10-6, the seventh air volume control valve 10-7, and the eighth air volume control valve 10-8 are adjusted to release specific odor gas in a specific time period according to a specific release amount. Within a period of time, if the feedback is not liked or satisfied, it is switched to model 2 input into the ship environmental control system according to the control of control unit 1. By analogy, the ship environmental control system is regulated to meet the crew's olfactory sensory comfort and mental pleasure requirements.
