Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

Paper focusing on the requirements of HFC refrigerants in a competitive environment. The best method of assessing trial refrigerants with a view to producing a ranking order, best to worst, is based on the measurement of refrigerating capacity in a properly designed calorimeter (3). A COP calculation derived from compressor shaft power is also available and gives the same ranking. Since efficiency is a function of both plant and refrigerant, the possibility exists that the same tests carried out in different equipment could produce a different ranking. The method described here gives a good general guide. The choice of blends for niche applications must be made with an appropriate level of sophistication in the overall design of the plant if a definite reduction is to be achieved in the total global warming effect.
