The next step in HVAC diagnostics

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 techs 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 doesnt 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 Governments 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

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

• 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
