Cooling Load Analysis on the KAIS Semeru Train PPI Madiun

Trains are a means of transportation with large capacity and low transportation costs. The cooling system on trains has an excessive load received by passengers, causing discomfort for passengers. The purpose of this study is to determine the capacity of the air freshener machine that is appropriate to the needs of the train. The method used is an analytical method, where data collection is used as a research guideline in solving the problem of cooling load on trains in this case related to the temperature in an area to be calculated. The air conditioning system plays an important role in supporting the achievement of thermal comfort levels. Thermal comfort in trains can be achieved if passengers get an ideal temperature supply, humidity level, and air movement from their environment. Based on calculations that have been done, KAIS Semeru has a cooling load of 94.3 kW.
