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:

Course Introduction

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 Summary

The 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.
