Introduction

Because heating and cooling equipment operate most efficiently when it is sized correctly, the HVAC industry has two main organizations that have developed standards for determining the heat capacity and air flow for both residential and commercial buildings. These standards have given uniformity the industry including contractors and manufacture alike. Furthermore, all governmental agencies have adopted these standards to be used as codes and normal practices within the field. When technician, HVAC designer, or engineer are designing a HVAC system, they will use ASHRAE and ACCA charts, tables, and forms to develop the proper sized equipment.
