by Hank Rutkowski. The essential companion to Manual J! Manual S shows you how to select and size heating and cooling equipment to meet Manual loads based on local climate and ambient conditions at the building site. Manual S covers sizing strategies for all types of cooling and heating equipment, 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. Published/Edition: Second Edition. ISBN/Book No.: ACCAS
