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.

COURSE TITLE: Heat Pumps for Heating and Cooling
COURSE NO: M06-035
COURSE PROVIDER: A. Bhatia
Heat Pumps for Heating and Cooling
Course Highlights

This online engineering PDH course provides fundamental knowledge of heat pumps so that you can make more informed decisions in choosing the correct system. The course covers the fundamentals, components, applications, installation of air source and geothermal heat pumps. Prior knowledge and a basic background in refrigeration and air conditioning will be helpful.

 

A heat pump is an electric device, which extracts heat from the air, ground or water and transfers it into the building. It is one of the most effective ways of heating water and indoor air while at the same time providing cooling (e.g. air conditioning), making them ideal for use in places where both air conditioning and heating are required.

 

A heat pump uses the principles of vapor compression refrigeration cycle to transfer heat from one place to another exactly in the same way as an air conditioner does. The beauty of these pumps is that they use the same refrigeration cycle for heating and cooling. Using a reversing valve, they change the coil serving as the condenser and the one serving as the evaporator. In cooler climates, people often purchase these pumps for use only as heaters. These units draw the heat from the ground or air and are often used commercially to heat offices and large apartment communities.

 

Their reputation started to grow since 2008, when heat pump sales in the United States and the Scandinavian countries have risen 40%. In some European countries heat pumps have already taken a significant proportion of the market for heating appliances and this is likely to be a long-term trend.

 

This 6 PDH online course is intended primarily for mechanical interested in gaining an understanding of heat pump application for heating and cooling.

COURSE TITLE: HVAC Chilled Water Distribution Schemes
COURSE NO: M05-008
COURSE PROVIDER: A. Bhatia
HVAC Chilled Water Distribution Schemes
Course Highlights

This online engineering PDH course discusses the history of chilled water distribution systems and the development of "variable primary flow system". Problems such as low delta-T syndrome associated with the chilled water pumping schemes are defined and also discussed. Finally, this course compares the advantages and disadvantages of primary-secondary and direct-primary pumping schemes.

 

In large commercial and industrial systems, chilled water system serves as means to transfer heat from building spaces to the refrigeration system. Initially, when energy costs were low, constant volume and primary-secondary systems provided a stable and simple operation of the chillers and distribution systems. However, as energy costs increased, particularly in the late 1970s, the efficiency of the chillers and the costs associated with operating the distribution system became more important. As a result, the need for new schemes to improve chiller performance and reduce energy costs drove the HVAC industry to advance chilled water technology, particularly in the manner that chilled water is delivered.

 

This 5 PDH online course is applicable to mechanical and HVAC engineers, process engineers, architects, building designers, contractors, energy auditors, facility managers who are interested in gaining a better understanding of HVAC chilled water distribution schemes.

  • The basic hydronic principles i.e. relationship of chilled water flow rate v/s cooling load and the energy savings due to adjustable speed pumps
  • How do constant volume chilled water systems different from primary/secondary arrangement
  • What is low delta-T syndrome and how it affects the chiller loading
  • What are the causes and mitigation measures to prevent low delta-T syndrome
  • Why distributed pumping arrangement is better than headered arrangement for constant flow systems
  • How do primary/secondary chilled water systems create hydraulically independent loops.
  • How to size the de-coupler bridge
  • The characteristics of control valves and why 2-way valve is better than 3-way valve in variable flow systems
  • How do the variable primary flow system compare with primary/secondary system in terms of cost and energy

COURSE TITLE: HVAC Pump Characteristics and Energy Efficiency
COURSE NO: M05-007
COURSE PROVIDER: A. Bhatia
HVAC Pump Characteristics and Energy Efficiency
Course Highlights

This online engineering PDH course provides the students with a firm understanding of the basic principles that centrifugal pumps operate under. Topics covered include the performance curve, series operation, parallel operation, the affinity laws, friction, specific gravity & viscosity, suction lift, and NPSH.

 

Most HVAC systems are designed to handle the maximum potential temperature extremes, keeping the building cool on the hottest days and warm on the coldest days. As a result, the HVAC system only needs to work at full capacity on the ten or so hottest and coldest days of the year. On the other 345 days, the system could be operated at reduced capacity.

 

HVAC pumps are generally designed for peak conditions and the output of these systems is controlled by mechanically constricting the flow with throttling valves. This wastes energy. By using a variable speed drives, chilled water flows can be matched to actual heating and cooling demands.

 

This 5 PDH online course is applicable to mechanical and HVAC engineers, process engineers, architects, building designers, contractors, energy auditors, facility managers who are interested in gaining a better understanding of HVAC pump characteristics and energy efficiency.

COURSE TITLE: Hydronic Systems
COURSE NO: M04-008
COURSE PROVIDER: A. Bhatia
Hydronic Systems
Course Highlights

This online engineering PDH course provides basics of the hydronic system operation and will familiarize the reader with piping system layout and operation, as well as provide an awareness of common circuiting arrangements. Topics to be discussed include auxiliary hydronic system components such as pumps, expansion tank, terminal units, distribution piping and fittings.

 

The circulation of hot water or chilled water to provide heat or cool the spaces is known as "Hydronic" system. It is a closed system where cold or hot water/steam runs through a heat exchanger and air is then blown over the heat exchanger to get the desired room conditions. Traditionally, HVAC systems are designed as All-Air Systems, which means that air is cooled at one location and is than distributed to the required space through ducts. All-Air Systems achieve the task of cooling a building by convection only. Hydronic system provides an alternative to cool/heat through a combination of radiation and convection inside the building.

 

Hydronic heating has three advantages over other types of heating systems. These advantages are comfort, efficiency, and versatile installation. With hydronics, you can move 40,000 Btu's through a 3/4" copper pipe through walls and between floors - or anywhere you need the heat - quietly and efficiently. A forced air system requires a lot of duct space, about an 8" by 14" duct, to move that much air with that many Btu's into a room.

 

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 hydronic systems.
