Overview of Vapor Absorption Cooling Systems

COURSE NO: M04-025
PDH CREDIT: 4
COURSE PROVIDER: A. Bhatia
Overview of Vapor Absorption Cooling Systems
Course Highlights

This online engineering PDH course provides an overview of absorption refrigeration technology. The aim of this course is to provide the working principle of absorption systems, types, applications, and economics of absorption refrigeration technologies.

 

The key feature of absorption cooling equipment is that it produces cooling by using heat energy as an input, rather than by using mechanical energy. The heat source is usually delivered via steam, hot water, or direct combustion. Compared to electrically powered chillers, they have high capital cost but these excel in operation where cheap, high grade heat or waste heat is readily available. These chillers do not need ozone-depleting refrigerants and many countries have begun identifying these machines as an energy and environmentally friendly equipment. Some states and utility companies provide subsidies and incentives such as tax rebates and higher depreciation. Absorption chillers can deliver from 25 to 2000 tons of refrigeration.

 

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.
