TLDR
In this article, a subcooler is provided in heat exchange relationship with the high pressure liquid refrigerant line flowing to the indoor coil, such that when a low pressure condition is sensed on the low pressure side of the system, the sub-cooler flashes a portion of the liquid fridge to the low-pressure side to maintain suction pressure to the compressor, while at the same time subcooling the liquid drizzler to the fan coil to increase its efficiency.Abstract:
