Principles and Applications of Air

This course includes the study of typical pneumatic control systems: The evaluation, maintenance, operation and troubleshooting of the air station, controlled devices, controllers, receiver controllers, transmitters, relays and switches which make up a pneumatic control system. An introduction to air compressors which drive a pneumatic system is also discussed. Also provided are the mathematic concepts similar to those described in Liquid Piping, as applied to the advanced study of the properties of air and heat calculations with the use of a psychrometric chart. Along with information, calculations and formulae used in fan operation and analysis, duct work and air distribution, air outlets, air balancing, belt and sheave analysis and air filters.

Motors and Applications

This course covers the techniques and calculations (including evaluation of expressions, order of operations, symbols of inclusion and power exponents) to determine load and sizing requirements for heating and cooling equipment. Included is the 24 hour method of load calculation and sizing of residential and commercial air conditioning and heating equipment as well as commercial refrigeration equipment.

The course also covers the application of single and three phase motors. Applications include motor types, operation, components, control hookups, motor feeder and branch circuit conductors, motor protection, motor control circuits and motor connections and testing, connections, transformer schematics and auto transformers of low and high voltage systems.

Predictive Maintenance and Piping Systems

This course covers why and how compressors fail, how to detect the cause of compressor failures and how to prevent repeat compressor failures. Commercial serviceable hermetic reciprocating compressors are covered, as well as Rotary and Scroll compressor operation and servicing. Also covered are maintenance of reciprocating, rotary and centrifugal air compressors and compressed air systems.

This course also covers types of distribution systems, materials and accessories found in water refrigeration systems. Also covered are concepts including evaluation of expressions, order of operations, symbols of inclusion, power exponents, proportions and computation of surface area uses applied to liquid piping operations. Included are: calculations and methods to determine pressure drops and pipe friction in water and refrigeration lines; techniques and methods to calculate the sizes of suction, discharge and liquid line of single and multiple piping systems in HVAC equipment and water lines; and methods and procedures to size water pumps and calculate pump head.

Electrical Systems and Heat Pumps

This course covers a study of single and three phase transformers. Included are the operation, inspection maintenance, installation and testing of single and three phase transformers. Delta and Wye load balancing for single and three phase transformers, sizing, protection, connections, transformer schematics and auto transformers of low and high voltage systems. A review of basic heat pump systems along with high efficiency split systems, heat pumps, variable speed and capacity products, including the familiarization, installation, operating sequence, operation and common servicing techniques. Current troubleshooting techniques will also be covered.
