The Performance Monitoring and Maintenance Audit of HVAC System
A. Bhatia, B.E.
Course Outline
This 4-hour course
provides overview of operation and maintenance (O&M) programs specifically
designed to enhance HVAC systems without significant capital investment. The
intent of this paper is not to provide hardcore maintenance or troubleshooting
aspects but an insight to O&M practices that can ensure the best performance
and comfort for your system.
The course is intended for use primarily to the students, end users, consultants,
architects, contractors and O & M professionals.
This course includes
a multiple-choice quiz at the end, which is designed to enhance the understanding
of the course materials.
Learning Objective
At the conclusion of this course, the student will:
Operation and maintenance
(O&M) best practices are defined as those activities, methods and approaches
that contribute to, or are directly responsible for, producing energy savings
while maintaining or enhancing indoor environmental quality and equipment reliability.
The HVAC system is a primary mode of providing comfortable and healthy indoor
environment for building occupants. It is very important that the performance
of the various equipments is monitored time to time and the maintenance activities
are integrated with the outcome of the observations noted down while monitoring
various operating parameters. A properly structured operation and maintenance
(O&M) program is thus necessary for optimum energy use, reliability and
indoor quality.
Keep in mind; it's always a good to check the manufacturer's maintenance recommendations
for a particular piece of equipment.
The course is divided into 2 sections:
PART I Monitoring and Analyzing Performance
PART II Maintenance Considerations

Course SummaryThe foremost step
of any service plan is to formulate a comprehensive schedule and proactive service
plan to avoid breakdowns and to ensure reliability of air-conditioning and refrigeration
system. Typically, the primary goal of preventive maintenance is reliability
but it should be redefined to include activities critical to energy-efficient
operation.
Keep an accurate log of all basic data such as compressor amps and volts, suction
and discharge temperatures and pressures, oil pressures, etc. This provides
a baseline for comparison with future data.
Inspections and corrective actions should be fully documented. Records on the
HVAC system should be maintained for at least five years and should be readily
available upon request.
Well-planned comprehensive maintenance will return dividends to the building
owner in assuring comfort, indoor air quality, and reduced operating costs.

Auditing and Conservation
The major energy use in the HVAC system is in the chillers followed by the water
pumps and the air-distribution system. For large installations, the secondary
energy use on the pumps and air-handling systems is significant. A 4-hour course
titled "HVAC Energy Auditing and Conservation"
provides insight to the performance evaluation of all other equipments associated
with building operations.
