FUNDAMENTALS OF REFRIGERATION AND AIR CONDITIONING

Catalog description

This course studies the history and evolution of refrigeration. The course details the theories about heat and temperature; its nature and relationship with refrigeration. In addition, the concepts of: pressure, temperature, compression, evaporation, condensation, refrigerant controls, piping, welding, tools, refrigerant handling, evacuation, loading and calibration of instruments are discussed; and how they interrelate according to the laws of thermodynamics. It includes the principles related to refrigeration theory and cycle, pipeline operations and refrigerant management, their nature and relationship with refrigeration and its applications. In addition, the student will be familiarized with the tools used in the refrigeration and air conditioning (HVACR) pipe, welding industry. The safety rules and handling of refrigerants CFCs, HCFCs, HFCS HCs and their derived mixtures as regulated by the EPA in the practical performance of their functions are widely explained.
