Water level control method of air conditioner

Abstract

The invention discloses a water level control method of an air conditioner. The water level control method of the air conditioner comprises the steps that whether the water level of condensate water reaches a preset low water level or not is judged; if yes, a condenser fan is controlled to run at the lowest rotating speed, a water fetching motor is controlled to run at the highest rotating speed, the condenser temperature T is detected, and the running frequency of a compressor is controlled according to the condenser temperature T; whether the condensate water level reaches a preset high water level is judged; and if yes, the condenser temperature T and the environment temperature T ring are detected, and whether the compressor is shut down or not is controlled according to the condenser temperature T and the environment temperature T ring. The water level control method of the air conditioner has the advantages of being accurate in water level control, safe, reliable and the like, the probability of shutdown protection can be reduced, and user experience is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a water level control method for an air conditioner. Background technique [0002] Air conditioners in the related art, such as mobile air conditioners, will generate a large amount of condensed water to flow into the water tank after long-term cooling or dehumidification mode operation. Usually, a water pump motor is used to drive the flywheel to spray the condensed water onto the condenser to cool the condenser. , while evaporating the condensed water in the tank. But sometimes the water pumping motor sprays the water in the water tank until the evaporation speed of the condenser is relatively slow, and the water level of the condensed water in the water tank still continues to rise, causing the air conditioner to seep into the ground. [0003] In order to control the water level of the air conditioner, a water level switch is usually used to control the shutdown of t...

AI Technical Summary

Problems solved by technology

If multiple water level switches are used, when the water level reaches a certain level, the speed of the condenser fan is controlled to decrease, and the evaporation rate is increased to reduce the accumulation rate of condensed water. When the water level reaches a high level, it is closed to control the shutdown protection of the air conditioner, but it cannot accurately control the air conditioner. The operating load of the air conditioner affects the operating comfort of the air conditioner, and it is easy to cause the condenser to be damaged due to excessive temperature
