دانلود کتاب HVAC Engineer's Handbook

This book contains in a readily available form the data, charts and tables which are required by the heating engineer many times during his daily work. The data is presented in a concise manner in order to facilitate the work of the heating and ventilating engineer. The book is designed for daily use and a comprehensive bibliography has been included for the benefit of those who wish to pursue the theoretical side of any particular branch. This ninth edition has been completely rewritten in order to bring it up-to-date with current practice and the most recent data available. Some of the sections have also been re-arranged to give a more consistent presentation and thus make it easier to find relevant information. A large part of the industry's work is concerned with modifications and alterations to existing buildings. Records and drawings of these are inevitable in Imperial Units and engineers who are faced with such information may need other data in the same units. The policy has therefore been continued of giving tabulated data in both SI and Imperial units although theoretical expressions are generally siven only in SI units
