COURSE TITLE: Variable Air Volume Systems
COURSE NO: M06-007
COURSE PROVIDER: A. Bhatia
Variable Air Volume Systems
Course Highlights

This online engineering PDH course discusses the HVAC air distribution system with focus on Variable Air Volume (VAV) systems.

 

In central air conditioning systems there are two basic methods for delivering air to the conditioned space 1) the constant air volume (CAV) systems and 2) the variable air volume (VAV) systems. As the name implies, constant volume systems deliver a constant air volume to the conditioned space irrespective of the load.

 

VAV systems, on the other hand, are designed to simultaneously meet a variety of cooling and heating loads in a relatively efficient manner.  The system achieves this by varying the distribution of air depending on the cooling or heating loads of each area.  The air flow variation allows for adjusting the temperature in a single zone without changing the temperature of air in the whole system, minimizing any instances of overcooling or overheating.  This flexibility has made this one of the most popular HVAC systems for large buildings with varying conditioning needs such as office buildings, schools, or apartments.

 

This 6 PDH online course is applicable to mechanical engineers, design and construction personnel, technical staff and facility personnel who are interested in gaining a better understanding of variable air volume systems.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • What is the operational philosophy of variable air volume (VAV) systems
  • What are the differences between pressure dependent, pressure independent and volume limiting VAV boxes
  • What are the various types of fans used in air handling systems including forward curved, backward curved, radial and aerofoil construction
  • What are the different types of cooling coils used in air handling systems and which among face split, vertical split and intertwined coils is appropriate for VAV systems
  • What is duct pressure classification and how it is used in selecting appropriate duct sheet thickness
  • How is duct design using equal friction method different from static regain and T-method
  • What are different types of outlets and which parameters govern their selection
  • What is difference between fan powered, single duct, dual duct and bypass VAV boxes
  • What are different types of VAV controls including direct digital controls
  • What are the common instruments used in acceptance testing and monitoring of VAV systems

COURSE TITLE: Overview of Chiller Compressors
COURSE NO: M04-027
COURSE PROVIDER: A. Bhatia
Overview of Chiller Compressors
Course Highlights

This online engineering PDH course provides comprehensive information on the chiller compressors. It addresses the key issues pertaining to the chiller compressor selection and their applications. The practical considerations and assessment criterion are also discussed in brief.

 

In HVAC industry, the refrigeration machine that produces chilled water is referred to as a "chiller". The majority of installations operating worldwide are based on the vapor compression chillers that use mechanical energy in the form of electric  motor to drive the cooling cycle. The vapor compression chiller packages are generally classified by 4 types of compressors namely centrifugal, reciprocating, screw and scroll.

 

This 4 PDH online course is applicable to HVAC engineers, facility engineers, architects, environmentalists, operations and maintenance personnel, as well as consultants and contractors who construct, build and manage facilities.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Operating principle of reciprocating, screw, centrifugal and scroll compressors
  • Key advantages, disadvantages, limitations and drawbacks of various refrigeration compressors
  • Efficiency ratings of various chiller options on peak load and part load
  • Factors affecting the efficiency of chiller compressors
  • Types of refrigerants used/recommended
  • Heat rejection options - air cooled vs. water cooled chillers
  • Reliability, maintenance, field serviceability of various chiller options
  • ARI standard 550/590 performance standard for defining part load performance ratings - IPLV vs. NPLV
  • Importance of peak load and part load analysis in determining the overall capacity and number of chillers
  • Series and parallel arrangement of chillers
  • Operational regimes, infrastructural availability and physical attributes affecting the selection of chillers
  • Procurement strategies, performance specifications, life cycle cost considerations
