Entry Requirements:

All candidates must have completed Technology 1, Technology 2, Technology 3, Electrical 1, Electrical 2, Electrical 3, Installation/Maintenance & Repair, Safe Handling + Technology 4 (Diploma)


This course includes the advanced aspects of air conditioning and refrigeration including central plant and air conditioning in depth. This course will enable the student to perform retrofitting work, conduct heat load calculations for quoting and installation purposes, ventilation rate calculations for commercial and industrial applications, calculation of system performance, capacity, advanced fault finding, evaporative cooling sizing and     design.


Upon successful completion of this course the student will have the understanding and skills to determine a systems operating parameters from a pressure enthalpy diagram, calculation of plant capacities, C.O.P., compressor efficiency, mass flow, heat rejection, confirmation of superheat and sub-cooling etc.  In addition: fault finding using a pressure enthalpy chart, heat load calculations for air conditioning and refrigeration applications, the retrofitting process, psychometrics. Although this is an in depth course the level is with-in the artisans / technicians scope of work.

This course is very popular with the medium to large corporate client running a central plant / ducted or indirect system and with persons wishing to have an in depth under standing of the trade.

Examples of Skills:

Central plant air conditioning / advanced fault finding using mollier diagrams / heat load calculations. Psychometrics, air flow rates and balancing, determination and calculation of ventilation rates, air changes per hour/ humidity/ maintenance schedules / evaporative cooling sizing and design.

Properties of air, humidification, calculations involving heat & mass transfer.  Air flow measurements, air changes, flow rates, duct balancing, define operating parameters, refrigerant blends/temperature glide, operational faults & remedial action.  Detailed practical mollier chart application, determination of plant capacity, C.O.P., Compression ratios, super heat & sub cooling, mass flow etc.
