| Abstract |
This handbook is a guide and reference for the planning, design, construction and operation of environmental control systems for underground rapid transit. The handbook follows the engineering sequence from criteria through load analysis, and from system conceptual design to selection of equipment. It covers a broad range of parameters, including temperature, humidity, air quality and rapid pressure change, and, to a limited extent, noise and vibration as related to environmental control equipment. The content of the handbook is divided into two volumes, Volume I (this volume), Principles and Applications, encompasses all of the above subject matter so that much of the environmental system design can be accomplished using the techniques, computations and related graphic data contained therein. |
