دانلود کتاب Analyzing field measurements: air conditioning & heating

This manual is intended to assist engineers and technicians with a background of use of temperature, pressure, humidity, air flow, and flue gas instruments, to interpret their readings of field measurements. This determination will indicate the deficiencies of the system tested and methods of correction. Improvement of operation nearly always results in reduction of utility costs. Simple displays and instructions will enable non-technical personnel to operate equipment efficiently at minimum energy costs. In multiple building installations, this type of control may save as much as 75% of maintenance time because you can analyze the condition of the system with the computer before you send out the maintenance man to make adjustments. Also, you may be able to predetermine the exact problem so that the same maintenance man will not have to spend time checking a number of items until he pinpoints the difficulty. The information in this book will assist building owners, maintenance personnel, contractors, and technicians in determining the operation of energy-using systems and methods of decreasing energy consumption.
