HVAC Systems 12 PDH Discount Package

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.

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.

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.
