Heating/Piping/Air Conditioning Engineering;Sep2007, Vol. 79 Issue 9, p54
The article looks at the issues involved when developing the details of the control sequence that will orchestrate HVAC systems. It is important to maintain stability while responding to the load swings associated with daily and seasonal variations in temperature and other parameters. The characteristics of each HVAC process and what is required for success in each process must be considered when a control sequence is developed. There are certain criteria to be met so that efficiency and performance enhancements will deliver intended results.
