Chapter 59--The Heat Pump. This is a new chapter giving information on the fundamentals, types, com ponents, performance, design, and selection of heat pumps. Chapter 40--Evaporative Apparatus for Heat Rejec tion. This is a new chapter giving information on water-cooling methods and equipment. Cooling tower theory, design, selection, operation, and maintenance are discussed. New data on spray performance are in cluded . Chapter +1--Evaporative Air Cooling and Humidifi cation. This is a new presentation of the operation of air washers and their use for humidification and de humidification. New information is given on evapora tive cooling, types of equipment, and design methods. Several new illustrations were used. Chapter 0--Dehumidification by Sorbent Materials. This chapter has been rewritten to include current information on solid and liquid sorption systems. A new section has been added on use of sorbents at ele vated pressures. New illustrations were included. Chapter 45--Automatic Control. This chapter was rewritten and enlarged to include IS new cuts showing application of controls for various operations. The description of control types and operation has been extended. Chapter 44--Instruments and Measurements. This chapter has been brought up to date by extensive revision. Chapter 45--Motors and Motor Controls. The section on classification of motors has been revised to indicate the nomenclature adopted by the National Electric Manufacturers Association. Chapter 0--Residential Summer Air Conditioning. A new section on gas-fired year-round air conditioners has been added. Chapter 47--School Systems. This chapter has been rewritten with emphasis on factors affecting the heat ing and cooling loads. Various types of heating, cool- ing, and ventilating systems are discussed. Chapter 0--Transportation Air Conditioning. The section on control of passenger bus air conditioning has been revised. Chapter 0--Snow Melting. A new chapter has been added riving a method of designing snow-melting sys tems. New tables and data are included. Chapter 55--Corrosion and Water-formed Deposits, Causes and Prevention. The section on use of resistant metals has been improved. Chapter 56--Water Services. The charts for friction loss have been enlarged. The section on electric water heating has been transferred to this chapter from the chapter on electric heating. Chapter 57--Codes and Standards. Several new standards have been added' and the correct editions of listed standards have been indicated. In addition to the changes in specific chapters out lined, numerous improvements nave been made in both text and illustrations. A complete index to Technical Data is contained in a 16-page section at the front of Tub Guide. For convenient reference to equipment to be se lected for various types of installations, this book contains & Catalog Data Section showing products of 309 manufacturers of heating, ventilating, cooling,and air-conditioning equipment. This section is preceded by a 16-page index listing equipment available un der numerous headings for most convenient use. The Guide Committee is pleased to give credit for Preparation of Guide maten&l for this edition to the ASHAE Technical Advisory Committees, particu larly those on Evaporative Cooling, Heat Pump, Heating and Air-Conditioning Loads, Hot Water and Steam Heating, Insulation, and Sorption. The staff of the ASHAE Research Laboratory has rendered valu able assistance to these committees. Many trade asso ciations, engineering societies, and other organira- tions mentioned in the text, in addition to individual engineers, both Society members and nonmembers, have contributed new material or reviewed present material to establish its authenticity. While it'is im possible to recognise all sources of information and help, the Guide Committee is pleased to mention the following, who have been very active in preparation of this volume: P. R.
