| Abstract: | Vapour compression/absorption modified hybrid heat pump system using ammonia-water as the working fluid has been presented. The experimental as well as the theoretical performance based on the exergy analysis has been given. The irreversibility rate (exergy loss) in the low pressure compressor is found to be the highest while it is found to be the lowest in the case of expansion valve. It is also found that the irreversibility rate in low and high pressure compressors as well as the solution pump increase as the ambient air temperature increases. The effect of ambient air temperature is found to be more pronounced for the desorber while it is found to be reversed in the case of solution heat pump. |
