And when the indoor evaporator is low in temperature, water vapor in the humid air can be condensed on the surface of the evaporator, and condensed water on the evaporator is collected and then drips from the surface of the heat exchanger. Because the surface temperature of the evaporator is low, the temperature of condensed water dropping from the surface of the evaporator is generally between 10 and 20 ℃, and the condensed water is a cold source which is worthy of being utilized, but the condensed water is generally lost and cannot be effectively utilized. In order to utilize the condensed water generated from the indoor unit, the indoor unit must be positioned higher than the outdoor unit so as to overcome the flow resistance of the pipeline by the gravity of the condensed water. Generally, the height difference between the indoor unit and the outdoor unit is very small, even the outdoor unit is higher than the indoor unit, which makes it difficult to apply the condensed water of the indoor unit to the outdoor unit or to apply extra work to send the condensed water into the outdoor unit, but this increases unnecessary power consumption and control difficulty.

This can weaken the evaporation cooling effect of water, and the range of the effect of the intensive heat transfer of condenser and complete machine efficiency promotion is not obvious.

Along with the cross section area of the flow channel is gradually reduced, the flow velocity of the fluid is gradually increased, the pressure is reduced, the pressure at the position with the minimum cross section area of the flow channel is lowest, the condensed water in the condensed water inlet 8 can be sucked, and therefore the problem that the condensed water cannot flow to the outdoor unit of the air conditioner by means of gravity due to the installation height is solved. The condensate drain pipe 18 guides the condensate generated in the indoor unit to the condensate inlet 8. And an electronic switch 17 is provided on the condensed water drain pipe 18.
