Heating, Ventilating, Air Conditioning and Refrigeration (HVAC-REF)

This program explores the fundamentals of refrigeration, heating, ventilating and air-conditioning (HVAC) systems theoretically and practically. The course will also discuss refrigeration principles, vapor compression cycle, refrigeration systems, and the conditions for a comfortable and healthy indoor environment, such as physiological considerations, environmental indices, and control of indoor air quality. The course will introduce the analysis of air-conditioning/psychrometric processes, and then discuss the estimation of energy to be added to (heating load) or extracted from (cooling load) a space. The course will also discuss different HVAC system components such as air handling units, water chillers, hot water boilers, cooling towers, evaporative condensers, fans and pumps, including the water distribution system, duct design and air distribution method as well as cooling load calculation..  The main course of this program is maintenance of HVAC and refrigeration system will be discussed thoroughly

 

Educational/vocational objectives

The expected HVAC and Refrigeration programs educational/vocational objectives are that, upon completing all training courses, the trainee will be able to:

• Apply principles of mathematics and applied science, to perform technical calculations and solve technical problems of the types commonly encountered in operation and maintenance technology careers.
• Demonstrate an ability to communicate effectively and function effectively with members of multi-disciplinary teams and with other workers in an industrial setting, including those from different backgrounds.
• Explain the performance of a simple refrigeration and multi-pressure systems.
• Determine the appropriate cycle for given climatic conditions and represent it on the pyschrometric chart.
• Identify the field of application of air conditioning systems and describe the components of different air conditioning systems.
• Choose appropriate air conditioning systems and select appropriate fan or pump.
• Describe various components of the air handling unit and fan coil unit and study their performance.
• Duct design and select air supply and return devices using tables.
• Calculate pressure loss in duct and fittings for chilled or hot water system.
• Design piping system and select piping materials, connections and fitting for chilled or hot water system.
• Calculate pressure drop in a piping network, pump head, and the size of a simple piping system
• Perform the maintenance on HVAC and Refrigeration systems.
• Calculate cooling loads using load calculation programs, select air conditioning components using catalogs and software.
