Experimental investigation of charge distribution in a vapour compression refrigeration cycle.

Author(s) : OZYURT B., EGRICAN A. N.

Summary

The vapour compression refrigeration cycle performance is seriously affected by refrigerant selection and amount used, as well as choice of cycle components like compressor, evaporator, and condenser. In this study, for better understanding of refrigeration system working conditions, the charge distribution at the system components and effects of different parameters to this distribution is investigated with R600a refrigerant. Two experimental setups are prepared for this purpose; first one is extended version of balance system in literature with replacing balance with load cells that have a higher precision. This system gives rapid results for the measurement but needs a data reduction process for frost formation. Second setup is based on principle of expanding the refrigerant, closed in components by quick closing valves at a specified moment of the cycle. The refrigerant amount can be easily calculated from pressure and temperature values for the expanded gas that have superheated condition.
