Writing for an audience ranging from undergraduates at maritime schools to engineers preparing for the Environmental Protection Agency's refrigerant certification exam, Harbach (engineering, United States Merchant Marine Academy) presents a textbook on the theoretical and practical aspects of refrigeration and air-conditioning in the context of marine operations. He presents chapters on the vapor compression cycle; refrigerants; compressors; evaporators and condensers; controls and accessories; controls and accessories; psychrometry and HVAC (heating, ventilation, and air conditioning) processes; cooling and heating load calculations; HVAC systems and components; absorption systems, multi-pressure systems, and low-temperature systems; and operations and maintenance. An appendix contains useful data tables and practice questions for the EPA certification exam. Annotation 2005 Book News, Inc., Portland, OR (booknews.com)
