Carrier System Design Manual Part 1: Load Estimating

Carrier System Design Manual Part 1: Load Estimating

Accurate cooling and heating load estimates are the foundation of any well-performing HVAC system. This essential volume of the System Design Manual provides engineers and industry professionals with the data, methodology, and practical examples needed to produce reliable load calculations—from initial survey through equipment selection.

Spanning eight focused chapters, this guide covers:

• Survey and load estimates

• Design conditions

• Heat storage effects

• Solar heat gain through glass

• Heat and moisture flow

• Infiltration and ventilation

• Internal and system heat gain

• Applied psychrometrics

Once the load is determined, the applied psychrometrics chapter serves as a critical bridge—connecting your load estimate directly to informed equipment selection.

Whether you’re a consulting engineer, a design professional, or an industry specialist, the text of this manual is offered as a general guide for designing HVAC systems. Judgment is always required when applying these principles to specific installations, and the publisher (Carrier) assumes no responsibility for any use made of the information.
