Greenhouse gas emissions reduction in the field of air conditioning: results available online

Releasing greenhouse gases in the atmosphere, such as carbon dioxide, is one of the causes of global warming. Among these compounds, refrigerants used in commercial air-conditioning systems are currently having a significant impact on climate change since, when released in the environment, remain in the atmosphere for very long periods. In this respect, the development of low global warming potential refrigerants is proving a considerable interest from industry, due to the increasingly restrictive environmental constraints.

Very important results in this field of research have been recently obtained by the University of Engineering and Technology (UET) Lahore, a prestigious Pakistani University with which Sotacarbo is starting a wide and profitable collaboration in several topics. The work consists of the experimental comparison of different kinds of hydrofluoroolefins (HFO), unsaturated organic compounds composed by hydrogen, fluorine and carbon. “The results of this study are very promising and easy to be industrially applied. The study confirms that HFO can assure similar – and sometimes better – performance than the commercial refrigerants, but with an extremely low environmental impact”, Assistant Prof. Dr. Muhammad Farooq (lead author of the research) said.

The work, recently published in the International Journal “Processes” (edited by the Multidisciplinary Digital Publishing Institute, MDPI), reports the experimental results obtained by UET Lahore and processed in collaboration with a wide international team of Sustainable Energy Research. This includes Sotacarbo and other partners like Heriot-Watt University and Aston University (United Kingdom), Karlstad University (Sweden), National University of Sciences and Technology (Pakistan) and Yalova University (Turkey). “It is the first result of a close and fruitful collaboration with UET Lahore, with the aim of developing energy technologies sustainable for the Earth”, Alberto Pettinau (co-authors of the research) said.
