COURSE TITLE: HVAC Variable Refrigerant Flow (VRF) Systems
COURSE NO: M03-014
COURSE PROVIDER: A. Bhatia
HVAC Variable Refrigerant Flow (VRF) Systems
Course Highlights

This online engineering PDH course provides an overview of VRF system technology. Emphasis is placed on the control principles, terminology, basic components, advantages and design limitations.

 

In recent years air conditioning systems have significantly changed. Variable Refrigerant Flow (VRF) also known as variable refrigerant volume (VRV) is a commercial HVAC system that can be configured to utilize a single condensing unit with multiple indoor evaporator units. The arrangement provides an individualized comfort control by varying the flow of refrigerant to each evaporator unit using sophisticated electronic expansion valve and inverter controlled variable speed compressor.

 

The system delivers excellent part-load performance and simultaneous heating and cooling in different zones. Unfortunately, the design of VRF systems is more complicated and requires additional work compared to designing a conventional air conditioning system.

 

This 3 PDH online course is aimed at the personnel who have some limited background in the air conditioning field and is suitable for mechanical, electrical, controls and HVAC engineers, architects, building designers, contractors, estimators, energy auditors and facility managers.

Learning Objectives

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

  • Understanding the difference between multi-split air-conditioning systems and VRF systems
  • Understanding the operating principle of a direct expansion split and a VRF system
  • Understanding the concept of thermal zone
  • Understanding how VRF systems with heat recovery are different from ordinary heat pump systems
  • Learning about the operation of thermostatic expansion valve (TXV)

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.

  • 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

COURSE TITLE: An Introduction to High Temperature Water Heating Plants
COURSE NO: M04-030
An Introduction to High Temperature Water Heating Plants
Course Highlights

This online engineering PDH course will introduce you to systems, equipment and design guidelines for high temperature water (HTW) heating plants.

 

HTW systems are used for heating multi-building facilities such as campuses and industrial and commercial activities. The advantage HTW systems have over steam heating systems is that the pressurized water in HTW systems has a much greater thermal storage capacity, resulting in smaller pipe and pump sizes. In this course you will learn about the different types of HTW systems, distribution schematics, hot water generators, pressurization methods, expansion vessels, pumps and controls.

 

This 4 PDH online course is intended for mechanical, industrial and plant engineers, as well as, maintenance personnel and construction professionals who are involved in the planning, design and construction of high temperature water heating plants.

Learning Objectives

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

  • Learning about the temperature and pressure parameters for high, medium and low temperature HTW systems

COURSE TITLE: Chiller Systems
COURSE NO: M04-006
COURSE PROVIDER: A. Bhatia
Chiller Systems
Course Highlights

This online engineering PDH course discusses the applications of chiller systems.

 

A chiller can be generally classified as a refrigeration system that uses either a vapor compression or absorption cycle to cool.  Both the absorption and the mechanical compression systems have the evaporation and condensation of a refrigerant in common. In both systems, the refrigerant evaporates at low pressure to absorb heat and then condenses at higher pressure to reject heat to the atmosphere. Both systems require energy to raise the temperature of the refrigerant for the heat rejection process.

 

The difference is that the mechanical chillers use reciprocating, centrifugal or screw compressors that are powered by electric motors whereas in the absorption cycle uses heat (usually steam or direct fire) to raise the refrigerant temperature. Mechanical chillers are most commonly used in residential and commercial buildings whereas absorption systems offer an excellent choice for industrial applications there waste heat recovery is an essential element of the process.

 

This 4 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 chiller systems.

Learning Objectives

  • How the mechanical compression cycle operates
