1. Chiller basics With Phil Rodin

2. Things to check when chiller is not running or is in alarm

3. Alarm showing water flow, pumps both chilled and condenser water types of flow switches

5. Alarm showing water flow, pumps both chilled and condenser water types of paddle switches

6. Alarm showing water flow, pumps both chilled and condenser water types of electronic flow switches Electronic flow switches have probes

7. Alarm Conditions High Pressure 1. Low water flow 2. Cooling tower 3. Strainers (locations?) 4. Valves (electric or manual types) 5. The entering and leaving water temp. 6. Approach temp

12. Alarm conditions Chilled water flow 1. Pumps 2. Strainers 3. Valves (manual and electric) 4. Flow switches 5. Water temp in and out 6. Approach temp

13. Alarm conditions Chilled water flow (cont.) PRV

14. What is the oil temperature? 1. Feel the tank or read with inferred. 2. Check control panel 3. Check for power 4. Think out of the box, How can we heat this?

25. Chiller Surging ASK YOURSELF????? 1. Is it a high or low end surge? 2. Are your amps going up or down? 3. The sound? a. Is it an elephant b. Is it a grumble

26. Chiller Surging (High & Low Surging) High Surge on Low Pressure Machines 1. Water temp. in and out. 2. Approach 3. Cooling Tower 4. Purge 5. Refrigerant levels

27. Chiller Surging (High & Low Surging)

28. Cooling Towers

29. Chiller Surging (High & Low Surging)

32. Chiller Surging (capacity control)

33. Chiller Capacity Control

34. Low End Surge 1. Water temp. In and out 2. Approach Temp. 3. Water pressure 4. Refrigerant levels

35. Low End Surge

37. Transducers & Sensors Types

39. Panel Codes 1. Carrier code 1111 2. York code 9675 aka YORK 3. Trane code ++--++ (different combinations)

40. How’s the Chiller Running? Is the chiller running in local? Is the chiller running in EMS? Are the pumps running? Are the valves open? Hand –off Auto (Think before going to hand)

41. Cavitation of Pumps 1. Strainers 2. Water pressures 3. Couplings 4. Valves 5. Primary or Secondary Loop

42. Questions (There is no such thing as a dumb question) ?
