A multistage condensing structure using a liquid dispensing means to transfer droplets of evaporative cooling liquid onto an air-cooled condenser, taking advantage of the conventional air-cooled condensing method and the evaporation method using a liquid coolant. To further increase the efficiency of the air conditioner, two or more condensing units can be arranged in tandem along the blowing direction of a common air blower. With two or more condensing units arranged in tandem, the contacting area between the evaporation surfaces and the air flow can be enlarged to increase the evaporation efficiency without significantly increasing the size of the air conditioner. The multistage condensing structure, with its continuous heat-exchange along the flow of the refrigerant in the coiled pipe, causes an increase in the subcooling condition in the refrigerant. This condensing structure can, therefore, achieve a much higher E.E.R. than the known method of air cooling.
