ACG Commissioning Guideline Appendix D
Appendix D
Sample Functional Performance Test Checklists
NOTES TO APPENDIX D
This appendix contains sample functional performance test checklists for a number ofcommonly used HVAC systems. The information for each system includes the following:1. a description of the system including its ma!or components
". a table showing all modes of operation with the status or position of key
e#uipment in each mode$. a se#uence of operations and
%. the functional performance test checklist that corresponds to the preceding
information.
There is no intention in the appendix to pro&ide sample checklists for all possible systems
included in any design. These checklists are intended to pro&ide basic information about
each system so that the functional performance test checklists will logically follow fromit and they will illustrate a le&el of detail that is appropriate in good commissioning
practice and to suggest a practical format.
The sample functional performance test checklists are generic' thus they do not apply to
any specific pro!ect and so the list of test items is generic not specific. Commissioning
agencies must de&elop functional performance test checklists for e&ery system includedwithin the scope of any commissioning pro!ect and those checklists must include e&ery
mode of operation and se#uence of operation co&ering normal abnormal and emergency
conditions that could occur in the specific design.
There is a Table of Contents on the next page listing the sample checklists included in
this appendix.
AC( assumes no responsibility for how the material in this Appendix might be utili)ed
by users of the (uideline' the users assume full responsibility for any and all liability that
may arise from any reference to or use of this material.

CHILLED WATER SYSTEM
8T2 +2C49*T9;
The chilled water system is typical of one that may be installed in a large office building.
The system consists of:♦ $ chillers CH,1 through CH,$. Chiller CH,1 is smaller than CH," and CH,$.
♦ 1 plate heat exchanger H2,1. 9t is located between the condenser water system
*,13
♦ A modulating chilled water bypass &al&e controls the differential pressure across
the supply and return piping.
The chilled water distribution system ser&es cooling coils in air handling units. The
system has the following modes of operation:
♦ hutdown
♦ ff
♦ tart,up
♦ Bree cooling

." The ++C system shall determine when the chillers are to operate based on a
building demand program by monitoring the &arious space temperatures as wellas the outdoor air temperature.
.$ Heat exchanger H2,1 shall be initiated as the source of chilled water when the
outdoor air is cold enough to permit this. The ++C system shall start therespecti&e chilled water pump and cycle the condenser water pumps and the
cooling tower fans in stages in order to maintain the chilled water supply

.1% The ++C system shall modulate the pressure bypass &al&e between the CH-line and the CH-4 line based on the difference between the two as sensed by a
differential pressure transducer in order to maintain water flow through the
chillers and H2,1 at all times. The differential pressure setpoint shall be changedto suit the chilled water pump operating at the time.
.10 The ++C system shall cycle the cooling tower fans in se#uence as re#uired to
maintain the condenser water supply temperature set point. This set point is to beinitially set at @3EB but shall be confirmed with the chiller manufacturer to ensure
maximum chiller efficiency is maintained and no surging takes place.
.1? The ++C system shall monitor the cooling tower fansF current draw and shall
annunciate an alarm upon a fan failure..17 ++C system shall pro&ide a 10 second time delay before the low speed is
energi)ed when switching from high speed to low speed fan operation.
.1@ The ++C system shall monitor a sump water le&el switch in each cooling tower.The ++C system shall open the two way water make up &al&e located in the
Gasement echanical 4oom when the water le&el is below normal. The &al&e
shall close when the desired water le&el is reached..1 The ++C system shall monitor the current draw of the Cooling Tower Biltration
pump and annunciate an alarm upon pump failure.
