Course Information
This free online course teaches you about ventilation and refrigeration process, as well as loading refrigerated cargo.
Marine Refrigeration and Climate Control is a free online course that begins by introducing you to the concept of ventilation and types of ventilation used on cargo ships, as well as to the different types of ‘sweat’ that occur. Engine room ventilation arrangement, as well as the importance of the engine room ventilation systems, will be covered in this course. You will learn about the difference between fans, blowers and compressors, as well as the factors to consider when selecting a fan and fan maintenance. The material will teach you about the maintenance and monitoring of shipboard ventilation components, as well as the working principles of a vapour-compression refrigerant cycle. The relationship between the refrigerant cycle and coefficient of performance, as well as the vapour compression cycle, will also be covered. You will be introduced to the brine and direct expansion system, as well as the main components of a direct expansion refrigeration system. You will also learn about the operations of a refrigeration system, as well as safety devices needed to protect compressors.
The course then explains the concept and functions of the ‘cascade system’, as well as the concepts of ‘coupling temperature’ and ‘optimum coupling temperature’. You will learn about the functions of the multiple compression and evaporator system. The features, functions, components, as well as advantages of the indirect expansion system, will also be covered. You will be taught about the preparations of holds for loading refrigerated cargo, precautions for loading, handling refrigerated cargo,
