All candidates must have completed Technology 1, Technology 2, Technology 3 and Electrical Two Courses Technology 1 + Electrical 1 + Technology 2 + Electrical 2 + Technology 3 = Technology 4 (Diploma)
Advanced in depth aspects of air conditioning and refrigeration, including central plant A/C, mechanical and electrical procedures applicable to the industry.
Includes the retrofitting process and heat load calculations as well as psychometrics and mollier diagrams. Although this is an in-depth course the level is within the artisans/technicians scope of work. This course is very popular with the medium to large corporate client managing a central plant, ducted or indirect system, with persons wishing to have an in-depth understanding of the trade.
Examples of Skills:
Central plant air conditioning, advanced fault finding using mollier diagrams and heat load calculations. Psychometrics, air flow rates and balancing, determination and calculation of ventilation rates, air changes per hour, humidity, maintenance schedules, burn out procedures and acid testing. Properties of air, humidification, calculations involving heat and mass transfer. Air flow measurements, air changes, flow rates, duct balancing, define operating parameters, refrigerant blends, temperature glide, operational faults and remedial action. Detailed practical mollier chart application, determination of plant capacity, C.O.P., compression ratios, super heat and sub-cooling, mass flow, etc.
