HEVAC Guide to Good Practice: Air Handling Units - 1991 (Download)
Air handling units vary greatly in size, function and complexity. Whether they be small or large, simple or complex, there are certain points to observe and pitfalls to avoid. It is the aim of this publication to guide the reader towards good practice, so that when the unit is installed it will perform in accordance with expectations.
The components most commonly utilised within air handling units are dealt with individually and for each heading there has been gathered a list of do’s and don’ts distilled from many years of experience. Fans though are not covered specifically since there is a separate HEVAC ‘Fan Application Guide’ which should be referred to.
With such an immense variety within the scope of air handling units the topics cannot be completely comprehensive, however, the major and most important aspects are fully covered.
