Abstract

The invention provides a drainage system and method for an air conditioner. The drainage system for the air conditioner comprises a water pan, a pressure sensor arranged at the bottom of the water pan, a control mainboard connected with the pressure sensor and a water pump for draining condensate water of the air conditioner. The pressure sensor is used for detecting pressure of water in the water pan, and a pressure value obtained through detection is transmitted to the control mainboard as a pressure feedback signal. The control mainboard outputs a control signal for increasing or decreasing the voltage of the water pump to the water pump according to the pressure value in the pressure feedback signal, so that the rotating speed of the water pump is increased or decreased. According to the scheme, the pressure sensor is arranged at the bottom of the water pan, the voltage of the water pump is adjusted according to the detected different pressure signals, and therefore the rotating speed of the water pump can be controlled to meet the need for the water drainage amount; and the water drawing capacity of the water pump is increased, noise can be lowered, and energy/electric energy can be saved.

Description

technical field [0001] The invention relates to the field of air conditioner internal unit drainage, in particular to an air conditioner drainage system and method. Background technique [0002] The existing air conditioning drainage system mainly uses a DC drainage pump on the indoor unit of the air conditioner to discharge the condensed water in the indoor unit. The amount of condensed water determines the load of the pump. When the amount of condensed water is large, the water level is high (deep liquid level) When the load of the water pump is large, the speed of the water pump will decrease when the load of the water pump is large. When the amount of water is less, that is, the water level is low (low liquid level), the load of the water pump is small, and the speed of the water pump will increase, thereby increasing the reactive power. At the same time, this part of reactive power will be converted into vibration and noise. Therefore, it is necessary to improve the ai...
