Abstract
Hydrofluorocarbons (HFCs) are now widely used in refrigeration and air -conditioning systems. These systems lose refrigerants through leaks a nd during servicing. This paper discusses the possibility of determini ng the emission rate of HFCs in buildings by applying tracer-gas techn iques. The measurement of the emission rate of an HFC refrigerant (R13 4a) using the concentration-decay technique was carried out in a singl e-zone chamber. The results were compared with measurements made using an SF6 tracer and the Pitot-tube traverse method.
