Electromechanical and Electronic Controls for HVAC/R Summary

Electromechanical and Electronic Controls for HVAC/R by Billy C. Langley

For one-semester courses in HVACR Control Systems. Exceptionally comprehensive, this text/lab manual covers the operation, use, troubleshooting, and repair of a wide range of HVACR controls - both electromechanical and electronic - focusing on the latest technology available. It uses an accessible conversational style that integrates the jargon encountered in the refrigeration and air conditioning field, and includes a lab section with 15 separate labs and accompanying lab sheets.
