This book will provide the reader with an understanding of the principles and practices of testing and balancing (TAB) heating, ventilating and air conditioning air and water systems. For both the novice and the experienced testing and balancing technician, it is a field reference book of procedures, equations and information tables. The initial section details general and specific balancing procedures for constant air volume systems, variable air volume systems, return air systems, and fans and fan performance. The author then goes on to cover fume hood systems and cleanrooms TAB, commissioning HVAC systems, centrifugal pumps and pump performance, analog and digital controls, and water balancing procedures using flow meters, system components and temperatures. Also examined are fans, pumps, air distribution, water distribution, motors, electrical, fluid flow, psychrometrics, refrigeration, and instrument usage and care. Many useful equations and tables.Fan Rotation Check the rotation of motors to ensure that fans are rotating in the correct direction. Certain centrifugal fans will ... To reverse the rotation on a threephase motor, change any two of the three power leads at the motor control center or disconnect. In some cases, you may ... Wiring diagrams for singlephase motors are usually found on the motor or inside the motor terminal box. Observe the fananbsp;...
