HVAC equipment engineers a basic review of fan engineering from an energy perspective.

his webinar offers HVAC equipment engineers a basic review of fan engineering from an energy perspective.  Fan terminology, performance characteristics, and fan laws will be presented with emphasis on fan selections that assure high energy efficiency and compliance with applicable codes and standards.  The presentation will also include an overview of emerging fan technologies that provide cost and energy benefits to high-performance HVAC systems. Participants will learn to read, interpret, and apply fan performance curves, and how to estimate fan energy usage. 

By the end of this webinar, attendees should be able to:

• Determine and apply the operating characteristics of a fan using fan curves.
• Estimate the annual energy usage of a given fan application.
• How to right-size a fan for best energy utilization.
• When, and when not, to use the fan laws. 

UNEP ask to stop using ozone damaging chemicals on air conditioners.

The ozone layer refers to a region of Earth's stratosphere that absorbs most of uv radiation form sun. The ozone layer is very small, it is vitally important to life.

Africa UNEP urging the suppliers like refrigerators and air-conditioners to stop chemical which damage ozone layers. We all know air conditioning units use HCFC cooling chemicals, it’s mainly damage ozone layer very badly.

UNEP representatives asked air-conditioning and refrigeration business owners to consider putting a limit on the amount of refrigeration and air-conditioning equipment

With decreased demand for HCFC, "new equipment coming into the country is cheaper and it's coming with alternatives.
