Fundamentals of air conditioning systems give a comprehensive understanding of air treatment and heat transfer principles in reducing energy cost, besides essential knowledge of fluid mechanics in air conditioning systems. This plays an important role in the operation and maintenance of air conditioning systems. This course will enable the attendees to be able to analyze and recommend the most effective solution available in air conditioning systems for operation and maintenance, enable them to utilize energy as possible as saving due to limited energy resources, and also you are a familiar and better understanding of all aspects related to efficient air conditioning system in the building.
