India ---------------------------------------------------------------------***--------------------------------------------------------------------- Abstract – The main objective of this work is to experimentally investigate the feasibility of employing ice as a cooling medium to improve air cooling performance of a portable cooler using latent heat of fusion. A portable air cooler has been fabricated with commercially available polyurethane insulation box integrated with galvanized iron conduit of 3*3 inch square cross section for air passage. This passage completely separates the airflow from ice while allowing the thermal conduction between ice and air. This system was experimentally tested under ambient temperature ranging from 34.6 ℃ and 30 ℃ . The test result show that the system is able to cool air upto 11.4 ℃ . The result also signifies that cooling performance of the system is subjected to variations in atmospheric temperature, room temperature and time. Key Words: Atmospheric temperature, room temperature, outlet temperature. 1.INTRODUCTION 1.1 Problem Statement In India, the average temperature is around 26°C (78.8°F), therefore various appliances such as air conditioners, coolers and fans are required to maintain a comfortable temperature for humans. Such equipment is fairly expensive, and not everyone can afford it. Students from other cities, those living in poverty, and lower middle-class families are particularly exposed to the summer heat in India. Traditional coolers and air conditioners are extremely expensive for these people to purchase, maintain, operate, and install. Due to the smaller rooms in hostels and rental apartments, these folks also have a problem with installation space. As these people are likely to travel to other cities and change places they also face problems of transporting bulky and heavy machinery and extra transport charges due to lack of portable appliances. The major goal of this study is to develop an alternate cooling technology as well as a device that is both economical and portable. This device is suitable for usage in hostels, homes, offices, and other settings. The temperature of the room has no scientific meaning that we can reliably assess. The temperature that is pleasant and appropriate for a person is determined by the individual, meteorological conditions, geographical location and other factors. As can be seen from the presented study, we have developed an alternative cooling method that may be of great assistance to those who are affected by extreme weather. We have developed a solution to India's heat wave dilemma that is both affordable and portable using mobile technology. 1.2 Objective a. To develop a portable air cooler that is compact , easy to use, provide better cooling effect without effecting atmospheric humidity content than traditional coolers, all at an affordable price range. b. Our main focus is on hostel students, students who live as tenants, and tenants from the lower middle class families. c. Development of this project aims to combat heat waves during the warmest months of the summer season, May and June. 2. LITERATURE REVIEW Bhupendra Sahare et.al [1], designed modifications to the existing cooler design. A mild steel refrigeration box was installed within the cooler tank, and the cooler tank was insulated from the outside with a rubber cushion to prevent heat loss. Except for the front face, which is a refrigeration box's door, all of the box's surfaces are in contact with tank water. A series of experiments in a controlled atmosphere within a room in the climate conditions of Raipur, Chhattisgarh, India were used to validate the suggested model. The box was stuffed with fruits and vegetables, and the same amount of fruits and vegetables were stored outside in the room, where daily weight loss was monitored. It was discovered that apples stored outside lose more weight than apples stored inside of a refrigerator box. When apples were kept inside the box, their temperature dropped, whereas when they were left outside, their temperature increased. In comparison to outside apples, the apples were in good shape. Inside, the weight was falling at a slower rate than outside. Manjunatha Y R et.al [2] proposed a solution that is the best alternative to conventional cooling techniques with temperature monitoring Bluetooth-enabled gadget with thermal energy that employs the Peltier effect to chill a specific region. This method allows us to detect both body temperature and environmental circumstances, as well as manage the temperature manually or automatically. The general operation is to use the Bluetooth module to monitor body temperature and ambient factors, which are shown on
