Description

Technical Field

[0001] This invention relates to a ship environmental control testing system and method, belonging to the field of ship environmental control testing technology. Background Technology

[0002] The function of a ship's environmental control system is to maintain specific environmental parameters in the cabin atmosphere, ensure the normal operation of various ship and marine engineering platform equipment, and provide good working and living conditions for the crew.

[0003] With the rapid development of the shipping industry, crew members have increasingly higher requirements for the quality of the cabin air environment. They are paying more and more attention to the presence of harmful gas molecules (such as hydrogen sulfide, ammonia, methane, ozone, etc.) and malodorous molecules (such as foot odor, body odor, body odor, fecal odor, and foul odor) in the cabin air environment. Summary of the Invention

[0004] The technical problem this invention aims to solve is as follows: Currently, most existing ship environmental control systems rely on conventional physicochemical techniques such as adding high-efficiency filters, electrostatic adsorption devices, and releasing air fresheners and deodorizers to filter, adsorb, dilute, destroy, and mask pollutants and odor molecules in the cabin atmosphere. However, these processes often result in secondary pollution, have relatively limited effectiveness, and the released chemical molecules are detrimental to the health of the crew. Furthermore, existing ship environmental control systems often rely on the crew's subjective judgment of the presence and intensity of harmful gas molecules and malodorous odor molecules as input conditions. This is highly subjective, lacks representativeness, and fails to meet the higher-level olfactory sensory evaluation requirements of the crew through unified qualitative and quantitative standard analysis.

[0005] To address the aforementioned technical problems, one aspect of the present invention discloses a ship environmental control testing system, characterized in that it comprises a control unit, a testing unit, an air conditioning unit, an odor removal unit, an odor generation unit, and a piping unit, wherein:

[0015] Preferably, the odor remover is a natural plant with strong adsorption and purification capabilities.

[0016] Preferably, the odor generator is a natural plant that produces a specific odor and is non-toxic and harmless.

[0017] Another aspect of the present invention discloses a testing method for a ship environmental control testing system. Using the aforementioned ship environmental control testing system, a comprehensive olfactory sensory evaluation can be performed. The method is characterized by comprising the following steps:

[0018] Step 1: Turn on the ship's environmental control testing system and enter self-test mode; if the ship's environmental control testing system malfunctions in self-test mode, it will enter fault mode.

[0019] Step 2: If the ship's environmental control test system is fault-free, it enters standby mode; in standby mode, the fifth tester sets the test condition parameters.

[0020] Step 3: If the test conditions and parameters of the ship environmental control test system are set, enter the preparation mode; in the preparation mode, the air conditioning unit is turned on, the odor remover in the odor removal unit is turned on, the odor generating unit is turned off, the test air inlet valve and test air outlet valve corresponding to the test unit are turned on, and the exhaust pipe fan is turned on for a certain period of time to achieve the set standard test conditions such as ambient temperature, humidity and air volume.

[0021] Step 4: If the ship's environmental control testing system meets the set test conditions, it enters the test mode. In the test mode, the first odor generator in the odor generation unit is turned on, releasing gas at the first release rate. The gas is then sent to the first test unit, the second test unit, the third test unit, and the fourth test unit through the pipeline unit. When a certain time period has elapsed, the fifth tester issues a collection command to collect the odor fragrance and odor intensity. The first, second, third, and fourth testers, according to regulations, feed back the odor fragrance and odor intensity results to the fifth tester. The fifth tester records the results of the first test and obtains the statistical values ​​of the permutation and combination of odor fragrance and intensity levels.

[0022] Step 5: After the first test is completed, prepare for the second test; turn off the odor generator and continue for a certain period of time, then send air through the pipeline unit to the first test unit, the second test unit, the third test unit, and the fourth test unit to achieve the set standard test conditions such as ambient temperature, humidity, and air volume.

[0023] Step 6: After the test preparation is completed, the second test is conducted; the odor generator releases gas at the second release rate, and the gas is sent into the first test unit, the second test unit, the third test unit, and the fourth test unit through the pipeline unit; when a certain time period is reached, the fifth tester issues a collection command to collect the odor fragrance and odor intensity. The first, second, third, and fourth testers, according to regulations, feed back the odor fragrance and odor intensity results to the fifth tester. The fifth tester records the results of the second test and obtains the statistical values ​​of the permutation and combination of odor fragrance and intensity levels.

[0024] Step 7: Following the steps in Steps 5 and 6, complete the tests on the odor generator at the third release rate, fourth release rate, nth release rate, and maximum release rate;

[0025] Step 8: Following the steps from Step 2 to Step 7, complete the tests for the second odor generator, the third odor generator, and the nth odor generator respectively;

[0026] Step 9: Following the methods and steps from Step 2 to Step 7, complete the tests under different permutations and combinations of the second, third, and nth odor generators and under different release rates.

[0027] Step 10: Turn off the first and second odor generators. The test ends when a certain time has elapsed. Based on the test results above, after comprehensive processing, the comprehensive odor evaluation index for the set test conditions is obtained.

[0028] Preferably, the odor intensity is divided into odor and fragrance, and the corresponding odor intensity levels are divided into A and B.

[0029] Preferably, the odor intensity can be divided into undetectable, barely detectable, mild odor, moderate odor, and strong odor, corresponding to odor intensity levels of 0, 1, 2, 3, and 4.

[0030] Preferably, the comprehensive evaluation index of olfactory senses can be divided into uncomfortable, generally comfortable, and comfortable.

[0031] Preferably, when the combination of odor intensity and odor fragrance level is A1, A2, A3, A4, B4, the overall olfactory sensory evaluation can be defined as uncomfortable; when the combination of odor intensity and odor fragrance level is A0, B0, B1, the overall olfactory sensory evaluation can be defined as generally comfortable; and when the combination of odor intensity and odor fragrance level is B2, B3, the overall olfactory sensory evaluation can be defined as comfortable.

[0032] Furthermore, if the comprehensive evaluation result of the above-mentioned olfactory senses is comfortable and generally comfortable, it proves that the release amount of the odor generator under the environmental conditions can produce an odor that is comfortable to the senses and meets the olfactory senses of the crew. This parameter condition can be used as the set odor adjustment input parameter of the ship's environmental control system.

[0033] Furthermore, if the overall evaluation result of the above-mentioned olfactory senses is uncomfortable, it proves that the release amount of the odor generator under the environmental conditions does not meet the olfactory senses of the crew, and the odor generator needs to be redesigned.

[0034] The advantages of this invention are twofold: First, the ship environmental control testing system and method of this invention can generate clean, fresh, and natural air with distinctive odors, meeting the higher-level olfactory sensory requirements of crew members. Second, the ship environmental control testing system and method of this invention can conduct qualitative and quantitative assessments of crew members' olfactory sensory abilities under relatively uniform standard testing conditions using the controlled variable method. This yields comprehensive evaluation results based on aroma level, odor intensity level, and olfactory sensory perception, providing relatively objective and accurate input conditions for the automatic control and adjustment of the ship's environmental control system.

[0047] Another aspect of this invention provides a testing method for a ship environmental control testing system, capable of performing a comprehensive olfactory sensory evaluation. The method, employing the aforementioned ship environmental control testing system, specifically includes the following steps:

[0048] Step 1: Turn on the ship's environmental control system and enter self-test mode M1. If the ship's environmental control system malfunctions, it will enter fault mode M0.

[0049] Step 2: If the ship's environmental control system is fault-free, it enters standby mode M2. In standby mode M2, the fifth tester P5 sets the test condition parameters. In this embodiment, the standard test condition parameters are set as follows: supply air temperature 25℃, supply air humidity 60%, external static pressure of the supply fan 500Pa, and total supply air volume 200m³ / h.

[0050] Step 3: Once the test condition parameters of the ship's environmental control test system are set, enter the preparatory mode M3. In preparatory mode M3, the air conditioning unit 300 is turned on, the odor remover 401 and odor remover 402 in the odor removal unit 400 are turned on, the odor generating unit 500 is turned off, the first test air inlet valve 601, the first test air outlet valve 602, the second test air inlet valve 603, the second test air outlet valve 604, the third test air inlet valve 605, the third test air outlet valve 606, the fourth test air inlet valve 607, and the fourth test air outlet valve 608 are turned on, the fan 609 is turned on, and the air supply volume of the first test unit 201, the second test unit 202, the third test unit 203, and the fourth test unit 204 is adjusted to 50 m3 / h to achieve the set standard test conditions such as ambient temperature, humidity, and air supply volume.

[0051] Step 4: If the ship's environmental control testing system meets the testing conditions, it enters test mode MT. In test mode MT, the odor generator 501 in the odor generation unit 500 is turned on, releasing gas at the first release rate. This gas is then supplied to the first test unit 201, the second test unit 202, the third test unit 203, and the fourth test unit 204 through the pipeline unit 600. When time t = 5 minutes is reached, the fifth tester P5 issues a collection command to collect the odor fragrance and odor intensity. The first tester P1, the second tester P2, the third tester P3, and the fourth tester P4, according to regulations, feed back the odor fragrance (A and B) and odor intensity (0, 1, 2, 3, 4) results to the fifth tester P5. The fifth tester P5 records the first test results (A0, A1, A2, A3, A4, B0, B1, B2, B3, B4).

[0052] Step 5: After the first test is completed, prepare for the second test. Turn off the odor generator 501 and continue for a certain period of time t=10min. Then, supply air through the pipeline unit 600 to the first test unit 201, the second test unit 202, the third test unit 203, and the fourth test unit 204 to achieve the set standard test conditions such as ambient temperature, humidity, and air volume.

[0053] Step 6: After test preparation is complete, conduct the second test.

When time t = 5 minutes is reached, the fifth tester P5 issues a collection command to collect the odor fragrance and odor intensity. The first tester P1, the second tester P2, the third tester P3, and the fourth tester P4, according to regulations, feed back the odor fragrance (A and B) and odor intensity (0, 1, 2, 3, 4) results to the fifth tester P5. The fifth tester P5 records the second test results (A0, A1, A2, A3, A4, B0, B1, B2, B3, B4) to obtain the odor fragrance and intensity levels (e.g., 3B1+1B2, 4B1, etc.). In this embodiment of the invention, a preferred implementation is that the test results can be recorded using a table in the following template format.

[0054]

[0055] Step 7: Following the steps in Step 5 and Step 6, complete the tests of the odor generator 500 at the third release level, fourth release level, nth release level, and maximum release level.

[0056] Step 8: Follow the steps from Step 2 to Step 7 to complete the second odor generator 502 test.

[0057] Step 9: Following the steps from Step 2 to Step 7, complete the tests of the first odor generator 501 and the second odor generator 502 under different release conditions.

[0058] Step 10: Turn off odor generators 501 and 502. The test ends when time t = 10 minutes has elapsed. Based on the above test results, a comprehensive odor evaluation index for this set test condition is obtained after processing.

[0059] In a preferred embodiment of the present invention, the odor remover 401 is equipped with a miniature coconut, and the odor remover 402 is equipped with aloe vera. The odor generator 501 is equipped with vanilla, and the odor generator 502 is equipped with orchid.

[0060] In this embodiment of the invention, a preferred implementation is as follows: Odor fragrance is categorized into odor and aroma, corresponding to odor fragrance levels A and B. Odor intensity is categorized into undetectable, barely detectable, mild, moderate, and strong, with odor intensity levels corresponding to 0, 1, 2, 3, and 4. The comprehensive olfactory sensory evaluation index is categorized into uncomfortable, moderately comfortable, and comfortable.

[0061] In a preferred embodiment of the present invention, when the combination of odor intensity and fragrance level is A1, A2, A3, or A4, the overall olfactory sensory evaluation can be defined as uncomfortable. When the combination of odor intensity and fragrance level is A0, B0, B1, or B4, the overall olfactory sensory evaluation can be defined as generally comfortable. When the combination of odor intensity and fragrance level is B2 or B3, the overall olfactory sensory evaluation can be defined as comfortable. The olfactory sensory evaluation comparison table is shown below.

[0062] Comprehensive evaluation of olfactory sense Aroma strength rating (A) Aroma strength rating (B) Odor intensity level (0) A0 - General Comfort B0 - General Comfort Odor intensity level (1) A1 - Discomfort B1 - General Comfort Odor intensity level (2) A2 - Discomfort B2 - Comfort Odor intensity level (3) A3 - Discomfort B3 - Comfort Odor intensity level (4) A4 - Discomfort B4 - General Comfort

[0063] Furthermore, if the comprehensive evaluation result of the above-mentioned olfactory senses is comfortable and generally comfortable, it proves that the release amount of the odor generator under the environmental conditions can produce an odor that is comfortable to the senses and meets the olfactory senses of the crew. This parameter condition can be used as the set odor adjustment input parameter of the ship's environmental control system.

[0064] Furthermore, if the overall evaluation result of the above-mentioned olfactory senses is uncomfortable, it proves that the release amount of the odor generator under the environmental conditions does not meet the olfactory senses of the crew, and the odor generator needs to be redesigned.
