Concentrations of hydrocarbon refrigerant exiting from RACHP equipment enclosures.

Number: 0006

Author(s) : COLBOURNE D., SUEN K. O.


Previous studies involving simulated leaks of hydrocarbon refrigerants from refrigeration, air conditioning and heat pump equipment found that the concentration of mixture exiting the equipment enclosure had a strong influence on the evolution of room concentrations. The present work investigates factors that affect these exiting concentrations, using wall type split air conditioner enclosures and a so-called variable enclosure, where the configuration may be changed to mimic different types of equipment. Important variables were found to include release position, size and number of openings and layout of internal components. These findings can be employed to assist with the design of equipment to help further minimise room concentrations in the event of a refrigerant leak.
