Problems solved by technology

[0003] Condensed water can be discharged by gravity or by a condensed water pump. However, when the drainage device fails, an alarm will appear for high condensed water level or coil overflow. In order to avoid equipment damage caused by condensed water, the refrigeration equipment will be controlled to shut down directly. This will cause the ambient temperature to rise, which will affect the IT equipment in the computer room or affect the experience of indoor users.
[0004] Aiming at the problem of controlling the air conditioner to stop cooling in order to avoid water overflow when the drainage device of the air conditioner fails in the prior art, no effective solution has been proposed so far

Abstract

The invention discloses a control method and device of an air conditioner. The method comprises the steps that the water level of a water pan of the air conditioner is detected, and the water pan is used for bearing condensation water generated by refrigeration of the air conditioner; whether the water level of the water pan is higher than the preset water level or not is judged; and if the waterlevel of the water pan is higher than the preset water level, a refrigeration control device of the air conditioner is controlled, so that the temperature of a heat exchange device of the air conditioner is higher than the dew point temperature of air. By means of the control method and device, the technical problems that in the prior art, when a water drainage device of the air conditioner breaksdown, the air conditioner is controlled to stop refrigeration in order to avoid water overflowing is solved.

Description

technical field [0001] The present invention relates to the field of air conditioners, in particular to an air conditioner control method and device. Background technique [0002] The basic principle of cooling air in computer room air conditioners or traditional comfort air conditioners is to use low-temperature coils to exchange heat with air. Since the air is mixed with dry air and a certain amount of water vapor, it is During the process, water vapor will condense on the surface of the coil, thus producing condensate. [0003] Condensed water can be discharged by gravity or by a condensed water pump. However, when the drainage device fails, an alarm for high condensed water level or coil overflow will occur. In order to avoid equipment damage caused by condensed water, the refrigeration equipment will be controlled to shut down directly. This will cause the ambient temperature to rise, thereby affecting the IT equipment in the equipment room, or affecting the experience...
