Further, the ratio of the inner diameter of the nozzle hole to the inner diameter of the liquid inlet section is recorded as a, and the value of a is 0.35-0.6.

The use of the nozzle leads to large pressure loss and noise, and the ratio of the inner diameter of the nozzle hole to the inner diameter of the liquid inlet section is limited in the range, so that the pressure loss and the noise of the refrigerant can be reduced while the refrigerant is uniformly distributed, and the use satisfaction of a user can be improved while a better air conditioning effect is obtained, and preferably, a is 0.45 or a is 0.5.

Furthermore, the lower end nozzle assembly further comprises an expansion section, one end of the expansion section is connected with the nozzle hole, the other end of the expansion section is connected with the mixing cavity, and the inner diameter of a connecting end of a cavity formed by the expansion section and the nozzle hole is smaller than the inner diameter of a connecting end of the cavity formed by the expansion section and the mixing cavity.
