Introduction

These courses will introduce the fundamental concepts of air-conditioning systems, the recent technologies and progress in the applications. It deals with the design considerations and the operations of typical air-conditioning systems for human comfort and air quality in commercial and non-residential applications. It will also outline typical types of air-conditioning systems and their components. The course critically examines the energy efficiency and usage in different air conditioning systems. The environmental issues will be also considered. The required load estimation and calculations of HVAC system design will be introduced. Practical hands-on exercises will be included in the workshop.

Keeping these machines running with least troubles and shutdown decreases the downtime of the whole system. Right machine selection appropriate to the right application, right machine operation, effective maintenance programs, reliable monitoring system, and skilled personnel capable of doing the right trouble shooting are essential requirements for prolong machine life. All the above can be achieved via deeper understanding of the machines construction and tolerances, the limits and constrains on their operation, and the more effective controlling methods.

This course will offer the opportunity to learn more about construction, operation, performance curves, control and troubleshooting of basic air conditioning systems. During the course participant’s discussion, comments, bringing up their own problems are welcomed and encouraged. Short tests on the course material will be performed to examine the degree of delivering the right and quality of the presented material.

Methodology

Our courses are highly interactive, typically taking a case study approach that we have found to be an effective method of fostering discussions and transferring knowledge. Participants will learn by active participation during the program through the use of individual exercises, questionnaires, team exercises, training videos and discussions of “real life” issues in their organizations.
The material has been designed to enable delegates to apply all of the material with immediate effect back in the workplace.
