When the air conditioner energy efficiency test is carried out, water is manually filled into the water receiving container 3 at the beginning of the operation of the machine, namely the first water box 31 and the second water box 32 are both filled with water. When the machine is operated, the second water pump 34, namely the submersible pump, works, the condensed water in the second water box 32 is conveyed to the liquid distributor 4, and the condensed water is evaporated on the surface of the condenser 12 to meet the energy efficiency requirement. After the operation is carried out for 1-2 hours, the water level in the second water box 32 slowly drops, when the float switch 35 is switched off, the second water pump 34, namely the submersible pump, does not work, the first water pump 33, namely the centrifugal pump, starts to work, the condensed water in the first water box 31 is conveyed to the liquid distributor 4, and the condensed water is evaporated on the surface of the condenser 12. When the condenser runs in parallel, no water is added manually, the condensed water flows into the first water box 31, the first water pump 33, namely the centrifugal pump, pumps a large amount of water when the water is large, and the water is conveyed to the surface of the condenser 12 through the liquid distributor 4 to be evaporated.
