Abstract: Utilizing condensing/defrosting water as additional coolant to cool the condenser coil makes cooling systems such as refrigerator, air conditioner, etc more energy efficient and reduces the possibility of condensing/defrosting water overflow from condensate collection pan. The compressed media flowing from bottom to top of the condenser coil makes more water evaporate. By introducing the working interval of cooling system makes the cooling system more energy efficient by optimally utilizing the low temperature condensing/defrosting water.
