3. INTRODUCTION
• There is an important correlation between quality and maintenance.
• Maintenance management has become an essential part of quality
systems.
• It is an invested rather than cost.
• Improving the quality of maintenance will lead to improved
effectiveness.
• Maintaining perfect equipment to maintain perfect quality of products.
3

4. DEFINITION
• Quality of maintenance is defined by Japanese institute of plant
maintenance as: create the conditions that prevent and control defects
in the process and systems to get to the zero defects stage.
4

5. IMPLEMENTATION
• MAINTANACE QUALITY APPLIED IN TWO PHASES:
1) PHASE I : QUALITY CONTROL PHASE
2) PHASE 2 : QUALITY ASSURANCE STAGE
• Use of preventive, predictive and proactive maintenance strategies.
5

6. MAINTENANCE QUALITY POLICIES
• The equipment shall be free from defects and under quality control
• Focus of the errors prevention
• Divides the defects in to main groups
• Effective application of quality assurance agent
6

7. OBJECTIVES
• To run the operation the longest possible time without breakdowns
• Keep the equipment maintained and fully functional at the time of
customer request
• Reducing cost of maintenance

8. THE REQUIRED INFORMATION
First : information of product
1. Number of defects and their impact on the product
2. Defects in each stage of the measurement
Second : special operation information
1. operating conditions for each sub-process
2. Prepared for the situation of the implementation of sub-module

9. APPLICATION OF TOTAL QUALITY
MANAGEMENT SYSTEM
• Link between quality and productivity
• Global quality system which is a feature of modern times
• The feasibility of some prevailing administrative systems
• The success of the application of the system comprehensive quality in
many educational institutions

10. HVAC
• INTRODUCTION
The Primary function of HVAC systems is to provide healthy and
comfortable conditions for occupants. Heating ventilation air
conditioning systems reduce the environmental impact of buildings in
several ways. Cooling equipment that avoids chlorofluorocarbons
eliminates a major cause of damage to the ozone layer.
10

11. HVAC system types
Each type of system has advantages and disadvantages :
Air cooled : Air cooled chillers
ADVANTAGES :
• Lower installed cost
• Quicker availability
• No cooling tower or condenser pump required
• Less maintenance
• No mechanical room required
11

12. Water cooled
Sea water cooled chillers
Fresh water cooled chillers
ADVANTAGES :
 Higher efficiency
 Custom selection in larger sizes
 Indoor chiller location
 Longer life

14. OBJECTIVES
We will study the components air handling systems in order to :
• Become familiar with the components
• Know their functions
• Become aware of possible problems

16. FAN AND PUMPS
• Contents :
Fan design
Fan performance
Fan duct system
Duct construction
Air duct design
16

17. FAN DESIGN
• Common types of fan :
Centrifugal fan : radial,forward curved,air foil,tubular,roof ventilator
Axial fan : propeller, tube-axial,vane-axial
Fan performance :
I. Fan volume flow rate
II. Fan total pressure, fan velocity pressure and fan static pressure.
17

18. FAN PERFORMANCE
• Major issues causing energy looses to a centrifugal fsn :
Circulatory flow between the blades
Air leakage at the inlet
Energy loss at the entrance
Partially filled passage
18

19. FAN DUCT SYSTEM
• Duct pressure changes
Static pressure
Velocity pressure
Total pressure
19

20. DUCT CONSTRUCTION
• Types of air duct
Supply air duct
Return sir duct
Outdoor air duct
Exhaust air
20

21. AIR DUCT DESIGN
• Systematic layout is easier to balance
• For exposed ducts appearance with the structure is important
• Compare alternative layouts and reduce fittings.

22. CONCLUSION
• The main objective of this study was accomplished the development of a
prototype QA programme for high maintenance. This is described and
illustrated in a two volume instructional document, titled maintenance QA
programme implementation manual.at the heart of the programme is an LOS
rating system that enables agencies to produce long term, end result
maintenance quality
