Static pressure self-adjusting control method and device and air conditioner

Abstract

The embodiment of the invention provides a static pressure self-adjusting control method and device and an air conditioner, and relates to the technical field of air conditioners. The static pressureself-adjusting control method comprises the steps that obtaining the actual static pressure value of a unit of the duct type air conditioner; obtaining change data according to the actual static pressure value and a preset static pressure value; and adjusting the opening degree of an air valve in an air duct of the duct type air conditioner according to the change data, so that the actual static pressure value of the unit of the duct type air conditioner equals the preset static pressure value. According to the static pressure self-adjusting control method and device and the air conditioner, the actual static pressure value is detected in real time, the opening degree of the air valve is adjusted automatically according to the change data of the actual static pressure value and the presetstatic pressure value and fed back and corrected for reasonable adjustment, the adjusting precision is high, the actual static pressure always equals the designed static pressure, unit static pressureself-adjustment is achieved, air volume and performance attenuation are avoided, and cleaning prompts can be given according to the static pressure adjusting times.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a static pressure self-regulating control method, device and air conditioner. Background technique [0002] The market share of central air-conditioning is increasing year by year, and the air duct machine is an important part, which is more and more widely used. The high static pressure air duct machine can be connected to the ultra-long air duct, and multiple air outlets and return air outlets are designed. During the use of the existing high static pressure air duct machine, dust will be deposited on the return air filter, evaporator and grille, the return air resistance will increase, and the air volume and performance will be attenuated, which will affect the stability and comfort of the unit. Contents of the invention [0003] The problem solved by the invention is the technical problem of air volume attenuation and performance attenuation of the air duct machin...
