The invention provides a method and device of preventing an indoor unit of a high-static-pressure duct type air conditioner from blowing water and related equipment. The indoor unit comprises a motorunit. A system judges the working state of the duct type air conditioner; if the working state is a refrigeration state, the working current and / or the working power of the motor unit is obtained; thesystem identifies whether the rated static pressure of the motor unit is matched with the length of an external air pipe or not according to the value relationship between the working current and a first current threshold value or between the working power and a first power threshold value, and conducts calculation to obtain a first matching degree between the rated static pressure and the lengthof the external air pipe after identifying the mismatching relationship; and finally, the system correspondingly adjusts the rotating speed of the motor unit according to the first matching degree, and the rated static pressure and the length of the external air pipe are matched. According to the method and device, after the rotating speed of the motor unit is adjusted by the system, the rated static pressure of the motor unit can be matched with the length of the external air pipe, the phenomenon that condensate water is blown out of a water pan by the indoor unit due to the excessively highair speed cannot happen, and the comfort level and the reliability of the duct type air conditioner are effectively improved.
Description
technical field [0001] The present application relates to the technical field of air conditioning, in particular to a method, device and related equipment for preventing the indoor unit of a high static pressure duct machine from blowing water. Background technique [0002] Ducted air conditioners are mainly used in the field of building engineering, and most of them transport the air from the air conditioner to the required location through the installation of ducts. Existing high-static-pressure ducted air conditioners leave factory with a high static pressure setting. During actual installation on site, sometimes due to reasons such as the terrain of the installation site, high-static-pressure ducted air conditioners are not connected to air ducts or connected to The air duct is relatively short, which will cause the rated static pressure of the air conditioner to not match the length of the external air duct, resulting in excessive wind speed of the air outlet from the a...
