Heat Exchangers Technology and Applications in Heat Exchanger Engineering

Abstract

Over the years, all parts of a commercial refrigerator, such as the compressor, heat exchangers, refrigerant, and
packaging, have been improved considerably due to the extensive research and development efforts carried out by academia
and industry. However, the achieved and anticipated improvement in conventional refrigeration technology are incremental
since this technology is already nearing its fundamentals limit of energy efficiency is described is ‘magnetic refrigeration’ which is
an evolving cooling technology. The word ‘green’ designates more than a colour. It is a way of life, one that is becoming more
and more common throughout the world. An interesting topic on ‘sustainable technologies for a greener world’ details about
what each technology is and how it achieves green goals. Recently, conventional chillers using absorption technology consume
energy for hot water generator but absorption chillers carry no energy saving. With the aim of providing a single point solution
for this dual purpose application, a product is launched but can provide simultaneous chilling and heating using its vapour
absorption technology with 40% saving in heating energy. Using energy efficiency and managing customer energy use has
become an integral and valuable exercise. The reason for this is green technology helps to sustain life on earth. This not only
applies to humans but to plants, animals and the rest of the ecosystem. Energy prices and consumption will always be on an
upward trajectory. In fact, energy costs have steadily risen over last decade and are expected to carry on doing so as
consumption grows. Refrigerants such as hydrochloroflurocarbons (HCFCs) are present in the ground source heat pump (GSHP)
systems and can pose a threat to the environment through beingtoxic, flammable or having a high global warming potential.
