The essential companion to Manual J! Manual S shows you how to select and size heating and cooling equip­ment to meet Manual J loads based on local climate and ambient conditions at the building site. Manual S covers sizing strategies for all types of cooling and heat­ing equip-ment, as well as how to use comprehensive manufacturer’s performance data on sensible, latent, or heating capacity for various operating conditions.
(115 pages)

Topics include:

■ Comprehensive performance data compared with ARI direc­tory data for air conditioners and heat pumps, and the presentation formats used by different manufacturers.

■ How ventilation loads and air distribution system loads affect equipment size and performance.

■ How to determine the condition of the air approaching the cooling coil when outdoor air is introduced into the return side of the duct system, including specific tables and charts.

■ Cooling-only equipment, air-to-air heat pumps, water-to-air heat pumps, dual fuel heat pumps, multispeed and variable speed equipment.

■ Why the “400 CFM per ton rule” is a myth, why the blower CFM is exclusively defined by the sensible heat equation, why lower DX coil air flow rates are compat­ible with humid climates, and why water source refrig­eration cycle equipment should not be sized to satisfy the design heating load.

■ Thermal balance point diagrams for heat pumps.

■ Economic balance points for dual fuel applications.
