Abstract

The invention discloses a method for controlling drainage of a unit and the unit. The method comprises the following steps that when it is determined that the unit needs to drain water off, and the temperature of the water in a water receiving tray is detected; when the temperature of the water in the water receiving tray is lower than a preset temperature, the water in the water tray is heated; and the heated water is discharged out of the water receiving tray. Therefore, when the water in the water receiving tray is frozen, and the unit has a drainage demand, the water in the water receivingtray can be heated through an electric heating device, so that the state of the water can be in a state that the water can be smoothly discharged (in a liquid state or low ice content state), then the unit can normally drain the water off, and a water pump is prevented from being damaged.

Description

Technical field

[0001] The invention relates to the field of units, in particular to a method for controlling drainage of a unit and a unit. Background technique

[0002] At present, condensate water is generated during the operation of the air conditioner, and the condensate water can be directly discharged through a drain pipe or through a water pump. However, when the weather becomes cold, the condensed water is easy to freeze and cannot be discharged normally, and it may even cause damage to the water pump. Especially in North America, where the temperature is low, due to factors such as beautiful outdoor design, drainage pipes arranged outside the building are usually not used to drain the condensate, but water pumps are used to drain and collect the discharged condensate To the designated location. Therefore, solving the above problems is beneficial to the promotion of air conditioners in North America and other places.

[0003] Aiming at the problem that the condensed wat...
