Experimental study on the heat exchange capacity of condensers in air conditioners

Measures heat exchange capabilities of several kinds of condensers combined by various copper tubes and fins at different air flow rates and fan speed, finding that the best condenser is that of inner groove finned copper tubes and plane fin in the upwind row and louver fin in the downwind row. Analyses the unbalanced distribution and reheating of refrigerant in different circuits for multi-circuit condensers.
