Overview of Vapor Absorption Cooling Systems

Course No. HV-4002

Credit: 4 PDH

Course Fee: $115.80 Purchase course

Subject Matter Expert: A. Bhatia, Mechanical Engineer

 

Overview

Absorption refrigeration is an excellent central air-conditioning method for plants that have excess heat that otherwise is discarded. Absorption chillers can deliver from 25 to 2000 tons of refrigeration.

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 for installation of vapor absorption cooling equipment.

This 4- hour 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.

This 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.

Once you complete your course review, you need to take a multiple-choice quiz consisting of twenty five (25) questions to earn PDH credits.
