COURSE OVERVIEW

This practical and highly-interactive course includes various practical sessions and exercises. Theory learnt in the class will be applied the following practical methods: 

(1) Industrial Facility Visit: Course participants will be taken to an industrial facility where they will practice testing, maintenance and troubleshooting. In case that this course is organized inside client premises (In-House), then client shall provide access to its HVAC and refrigeration workshop for practical sessions. 

(2) HVAC Simulator: Participants will use in the class the state-of-the-art HVAC Simulator to practice some of the skills learnt. 

 

This course is designed to assist experienced practitioners review and become more familiar with the particular system parts required for the design, installation, and maintenance of heating, ventilation and air-conditioning systems for all types of institutional, commercial, and industrial building envelopes. As the participant progresses through this five-day course, it will also serve as a refresher providing information about HVAC safety requirements, improved healthy indoor air quality, and emission reduction strategies.
 

During the course, there will be opportunities to practice using the ASHRAE Pocket Guide for Air Conditioning, Heating, Ventilation & Refrigeration. This easily carried reference provides fast, authoritative HVAC&R information on site. It is packed with practical and useful information that; includes properties performance and pipe sizing for new refrigerants, new data on refrigeration safety, ventilation requirements for residential and non-residential occupancies, occupant thermal comfort, more extensive data on sound and vibration control, thermal storage, radiant panel heating and cooling, air-to-air recovery and more. The participants also will receive a summary review of how to source HVAC related, building envelope, electrical, fire protection, ozone depletion protection, back-flow, and cross-connection controls codes and standards. 

 

Slide shows of installed operational energy management systems computer controls and instrumentation will enable a broader understanding of future real time data logger systems. The participant will learn about HVAC utilization of advanced metering infrastructures, automated water meter readings for leak detection of district chilled water loops, and end user consumption. Demand response electricity systems using smart meters controlling; air conditioning, thermal storage systems, lighting, variable speed motors for fans, and pumps. These applications plus studying the re-use of waste-water produced by HVAC systems supplying grey-water, are tools HVAC professionals may add to their portfolio of utilities cost reduction for building operations. Similar to energy management systems demand responsiveness is easier, less expensive, and simpler when the control protocol is incorporated into the original design. Practice work sheets will be made available to prove these systems are capable of tracking emissions reductions, and providing an additional revenue stream for building owners by lowering energy consumption. 

In class exercises for selecting correct equipment, loop checking sequence of operations and locating control points for HVAC systems will provide familiarization of the products available on the market today. A particular emphasis will be on understanding the advantages and disadvantages of commonly available types of electric, pneumatic, self-powered; sensors, actuators, valves, dampers, direct drives, analog and digital controls.  We will also review the different types of compressors, coils, exchangers, filters, condensers, dryers, chillers, expansion tanks, cooling towers, split-systems, forced air, boilers, associated piping, duct work, insulation, and common trade practices used in HVAC applications today. 

 

An introduction to predictive, preventative, troubleshooting, and emergency repair maintenance tips will be taught along with a re-cap of balancing air, and water systems. How to source information to maintain glycol densities, chemical treatment biocides and corrosion inhibitors, air handler unit ultraviolet lights for continuous coil cleaning, and disinfection, should help ensure the buildings investors realize improved life cycle costs, minimal downtime for equipment servicing, and public health protection, Worker safety will be reviewed to ensure clear communications between building operations and the personnel working on the of equipment. A strong emphasis will be for HVAC professionals to learn how to have a written safety plan detailing procedures for lock-out, and tagging, the importance of following original manufacturer's information for installation, starting up, and shutting down, will be reiterated throughout the course. 

The course will finish with examples of emerging dual use technologies such as dedicated fire protection lines as a component of the distribution network for deep lake or seawater district cooling systems, grey-water heat pump systems, types of building roofs, road, and building thermal energy systems. A basic introduction to the application of electricity power producing high temperature fuel cells, internal combustion engine, micro-turbine, distributed electric power co-generators use-able waste heat for domestic hot water, heating, and cooling applications will be presented. 

 

The course is condensed and assumes that the participants have prepared themselves by self-study of the ASHRAE e-book for Air Conditioning, Heating, Ventilation, Refrigeration prior to attending. In addition to the e-book, the delegates should bring their scientific calculators.
