  1. The next step in HVAC diagnostics

  2. Fieldpiece • HVAC/R specialized (17 years) • Needs are different • Minor market for our competitors

  3. Adolfo Wurts • BSME from Cal Poly Pomona • Specializing in HVAC/R • Fieldpiece Employee for 6 years • Spoken with 100s of HVAC professionals • Developed Field Guide based on direct HVACR technician input

  4. Fieldpiece Products • New product ideas come from HVAC technicians • Measure success: make the HVAC/R tech’s job easier, faster, safer, and/or better • Result: Fieldpiece is the leader in HVAC/R

  5. Fieldpiece Parameters Tested • Test most HVAC/R parameters

  6. Work How Tech Works • Modular

  7. Modularity Example: Superheat • ARH4 to get Target Superheat • ASX24 to get Actual Superheat

  8. Work How Tech Works (2) • Standalone

  9. Trends: Increased Attention to Conservation • Increased attention to conservation • Nobody wants another power plant • Not the government • NIMBY • Not the power companies

  10. Trends: Large portion of Energy Going to HVAC • 11.1% of US electricity costs are for HVAC (residential and commercial, DOE 2001 data) • This doesn’t count combustion for heating • Huge energy savings potential

  11. Trends: Higher SEER Mandates • High SEER equipment being installed • Most A/Cs running at 50-80% of rated efficiency • High SEER systems are more complicated

  12. Trends: Government’s Increased Interest • Title 24 • CA standard for AC service • Superheat chart • Target evaporator exit temperature

  13. New Fieldpiece Products to Improve Efficiency • Superheat and Subcooling heads • Evolution of products • AOX2 combustion check

  14. Benefits of Modularity • One Display and many accessories • Use DMM functions (Hold, min/max, etc.) • Easy to inexpensively expand • Use it your way • Stick meter • Electronic handle • Data logger • Remote it

  15. Bright Idea: Field Guide • Requires less technical competency • Easy to use, step by step direction • Fast, clear clean • More tests will actually be performed

  16. Tests Currently Available • Target Evaporator Exit Temp • Superheat • Subcooling • Combustion Analysis

  17. Target Evaporator Exit Temperature

  18. Superheat

  19. Subcooling

  20. Combustion

  21. Data Management • Real time displayed • Stores tests in memory • Stored with Customer ID: • Stored with time stamp

  22. Works With A PC • Does not require a PC to work • Transfer files to and from a PC for customer tracking • Bring previous tests to a jobsite • Keep track of work at the office • Download updates from Fieldpiece

  23. Field Guide Manual • Sections for each switch position • In Depth info on topics • Shows Input and Output Forms • Shows the best way to get accurate results

  24. Future Switch Positions • Check Me! • Green Box • CFM • Mini Split • Compressor Check • Other?

  25. Field Guide Updating • Connect to a PC via USB • Download update, simple instructions • More Switch positions • Expand Current Switch Positions

  26. Check Me! • Best one point in time diagnosis of an AC system • Looks at the system holistically • Developed from data of over 100,000 real world AC units

  27. Green Box • The best system for monitoring and diagnosing residential and light commercial HVAC • Continuously monitors ten system points • Wireless comm. between evaporator and condenser • Notifies residents of problems • Technician can decode the diagnosis of the AC via a Field Guide

  28. CFM • Helps tech easily perform CFM measurements from current testing methods • Performs basic air balancing calcs • Helps technicians find % Duct Loss and Leaks through simple measurements

  29. ? • Mini Split? • Compressor Diagnosis? • ?

  30. Field Guide • A greener America • More systems will run at better efficiency • Easier testing = more likely to happen • Easier service management

  31. Call to Arms • As educators you can make the biggest difference in the future • Save the earth for future generations • Ensure that students learn the proper techniques and procedures

  32. Benefits to Educators • Easy to teach • Easy to use • Inexpensive • Teacher deals (50% off direct credit card order) • Student deals (distributors get 10% off for student orders) • You can use the opman as a textbook/supplement
