SAIRAC FREE-TO-ATTEND PROGRAMME

WEDNESDAY, 4 JUNE 2025 – ENERGY / ENGINEERING

DAY 1 WILL COVER TOPICS AROUND ENERGY AND ENGINEERING While refrigeration technology has brought numerous benefits, it also has environmental implications that cannot be overlooked. The production and use of refrigerants, the energy consumption of cooling systems, and the disposal of refrigeration equipment all contribute to environmental challenges.

Refrigerant emissions: Many traditional refrigerants, such as chlorofluorocarbons( CFCs) and hydrochlorofluorocarbons( HCFCs), have been found to deplete the ozone layer and contribute to global warming. Although these substances are being phased out under international agreements like the Montreal Protocol, their replacements, such as hydrofluorocarbons( HFCs), still have a high global warming potential( GWP). As a result, there is ongoing research into developing more environmentally friendly refrigerants with lower GWP, such as hydrofluoroolefins( HFOs) and natural refrigerants like ammonia and carbon dioxide.

Energy consumption: Refrigeration systems are energy-intensive, and their widespread use contributes significantly to global energy consumption. The energy required to power refrigeration systems often comes from fossil fuels, leading to greenhouse gas emissions and exacerbating climate change. Improving the energy efficiency of refrigeration systems is a critical focus area for reducing their environmental impact. Innovations such as variable-speed compressors, advanced insulation materials and smart thermostats are helping to make refrigeration systems more energy-efficient.

Refrigeration engineering focuses on the design, installation, maintenance and troubleshooting of cooling systems. It involves a combination of mechanical engineering principles, thermodynamics and heat transfer to create efficient and reliable refrigeration systems.

Global warming routes: how to enhance efficiency in hydronic systems granting long working life of this equipment.

To reduce CO₂ emissions in our sectors means first producing units that are extremely efficient and reducing input energy for the same amount of cooling or heating energy, and second to produce units for cooling and heating with refrigerant that has low GWP.
