Abstract

In addition to Greenhouse Gases (GHGs), climate change can contribute to global warming. Global warming is defined as a change in climate that causes an increase in the earth's average temperature. Ambient temperatures that are too hot can be dangerous to one's health. Therefore, this hot ambient temperature is not good for a baby when they are indoors or outdoor because baby's skin is very sensitive and can cause heat-related illnesses. Therefore, most parents use baby strollers to take their children for walks outside or indoors to avoid exposure to direct sunlight. However, if the stroller is not monitored properly it can cause the baby to feel uncomfortable with the comfort temperature in the stroller. This comfort temperature can cause some illnesses to the baby such as heatstroke. This happens because there are some strollers that do not have good ventilation when the stroller is running or static. Due to that, this study will be conducted focusing on thermal comfort on baby stroller during outdoor activity. To achieve this focus, several studies have been done. Such as thermal comfort, fabric duct type and so on. In addition, to ensure that the temperature and velocity of the air is achieved well, the objective of this study will be implemented. Concept Screening and Concept Scoring methods are used to select the best design concept that adheres to the project's main idea in order to meet the objective. To achieve good air distribution in the stroller in this project, a 20 mm fabricated fabric duct was used. Two locations—the food court of MITC Melaka and Tasik Ayer Keroh Melaka Recreation Park (outdoors)—were used for the experiment (indoor). There are three tests, and measurements of the temperature and air velocity are made. Each temperature and air velocity at both locations reading will be taken every 30 seconds, within a 30 minutes and for the air velocity data experiment on comparison diameter size was taken for 15 minutes. The data values will then be compared using a fan with fabric duct and without. After comparison, the temperature for the fan with fabric duct can reach the baby's average temperature at 37.5 degrees Celsius. It shows that the performance of the fan with fabric duct is better than without inside the stroller.
