Introduction
The purpose of a Heating, Ventilating, and Air Conditioning (HVAC) system is to provide and maintain a comfortable environment within a building for the occupants or a suitable environment for the process being conducted. The control system must be designed, set up, and operated to recognize changes and to maintain the space temperature at the desired value. With the rapid increase in installations of direct digital control (DDC) systems, it became necessary to understand the basics coverage of DDC systems.
This training course includes necessary procedures in operation and maintenance of DDC systems, particularly in the initial checkout and operator training course on newly installed systems. Those procedures are also applicable to the re-commissioning of existing DDC systems and recurrent training course of DDC system operators and maintenance technicians. The training course covers the HVAC control system's functions and the interactions between the control system and the components of the HVAC systems. Also, the troubleshooting of the DDC system will be discussed in this course.
This training course will highlight:
- Classifications and components of HVAC systems
- Functions of HVAC control systems
- Types of HVAC control systems
- DDC systems architecture, operation, and maintenance
- Troubleshooting of DDC system
Objectives
By the end of this training course, participants will be able to:
- Understand the fundamentals and types of HVAC systems
- Identify the different types of HVAC control systems.
- Understand the basics of the DDC system
- Understand the operation and troubleshooting of the DDC system
- Understand the maintenance and testing of the DDC system
Training Methodology
This training course will utilise a variety of proven adult learning techniques to ensure maximum understanding, comprehension and retention of the information and innovative methods presented. This includes presentation of theoretical concepts, team and individual exercises, case study analyses, educational videos and real-life applications. Participants in this training course will receive a thorough training on the subjects covered by the training course outline.
Organisational Impact
After the training organization will obtain employees capable of setting up effective design, operation, and maintenance of HVAC DDC system, which leads to:
- Reduce the consumption and expenses of energy
- Retain high air quality and desired temperature
Personal Impact
The training course includes a modern approach to understand the fundamentals of HVAC systems. Also, understanding the setup, operation, and maintenance of the HVAC Control system will be aimed. Participants will be able to get in-depth knowledge with strong practical applications to set up, operate, maintain, and troubleshoot DDC HVAC systems
