In the technical scheme, the condensed water of the heat exchanger 1 is pumped to the upper part of the heat exchanger 1 through the water pumping spraying pipeline, and the heat exchanger 1 is efficiently cooled by using the cold energy of the condensed water, so that the energy efficiency of the air conditioner is improved while the energy is saved and the environment is protected. The water collecting part 2 comprises a water collecting tray, and the technical scheme is particularly suitable for window type air conditioners, wherein the water collecting tray is constructed on a base plate of a window type air conditioner, condensed water generated by an indoor heat exchanger is collected and then utilized by the water pumping spraying pipeline, and the structural layout is more reasonable and feasible.
The flowing direction of the condensed water in the spraying pipe 31 is a first direction, a plurality of spraying holes 311 are arranged on the pipe wall of the spraying pipe 31, and the water outlet areas of the spraying holes 311 are gradually increased along the first direction; or, along the first direction, the plurality of spray holes 311 are divided into a plurality of groups which are sequentially arranged, and defined as a spray hole group, the water outlet areas of the spray holes 311 in each group of spray hole groups are the same, and the water outlet area of the spray holes 311 in the spray hole group upstream in the first direction is smaller than the water outlet area of the spray holes 311 in the spray hole group downstream in the first direction. The design can ensure the outlet uniformity of the condensed water after being pumped to the spray pipe 31, and further ensure the uniform heat exchange of the condensed water to the heat exchanger. It is to be understood that the plurality of shower holes 311 should be formed at a side of the shower pipe 31 facing the heat exchanger 1.
However, the size and number of the spray holes 311 and the length of the spray pipes 31 all have a critical influence on the outlet speed and uniformity of the condensed water, and it is considered that the outlet speed is set to the maximum value as far as possible by general researchers under the condition that the conditions allow, and thus the maximum energy efficiency of the air conditioner can be ensured, for this reason, the inventors have found through a large number of experiments and data statistics that, when the outlet speed of the spray holes 311 is 0.01m/s, the energy efficiency of the air conditioner can substantially reach the maximum value at this time, and further increasing the outlet speed cannot significantly improve the energy efficiency of the air conditioner (as shown in fig. 5), and thus, the inventors have conducted intensive research on the basis of the optimal outlet speed of 0.01m/s, and have found that: the length of the spray pipes 31 is L, the number of the spray holes 311 on each spray pipe 31 is i, the spray holes 311 are round holes, the diameter of the minimum water outlet area in the i spray holes 311 is d1, the spray holes 311 are arranged in rows at equal intervals along the first direction, the minimum interval between any two adjacent spray holes 311 is n, and M rows of spray holes 311 are arranged in the spray structure (for example, the length of the spray holes 311 is L in the figure)6, two rows of spraying holes 311 are formed in a single spraying pipe 31, and if three spraying pipes 31 are arranged in the spraying structure, six rows of spraying holes 311 exist, that is, M is 6), and 2.7mm is designed at the moment2≤M(L2+i2n2-2iLn)/i≤106mm2。
As shown with specific reference to fig. 6, there are:
di＝d1+(i-1)Δd
in practical application, i is generally large (generally hundreds of numbers, far greater than 1), so i-1 ≈ i, 2i-1 ≈ 2i, and the simplification is as follows
Assuming that the first water outlet hole is close to the root of the shunt tube (the leftmost end of fig. 6, not shown in the figure), and the last water outlet hole is close to the rubber cover (the rightmost end of fig. 6, not shown in the figure);
bringing formula (2) into formula (1) to obtain
Since Δ d is a small quantity, the product of the second term in the above equation is also small and negligible.
According to the models with different cold capacities, under different working conditions and wind gears, the water yield range of the condensed water is 1.3-50ml/min, and the optimal water flow speed is 0.01 m/s.
Unifying the units in the formula into mm, and calculating to obtain:
then M (L) is obtained2+i2n2The value range of-2 iLn)/i is 2.7mm2-106mm2。
