Embodiment Construction

[0046] During the use of the existing high static pressure air duct machine, dust will be deposited on the return air filter, evaporator and grille, which will increase the return air resistance, cause air volume attenuation and performance attenuation, and affect the stability and comfort of the unit. The designer of the present invention found in the research that when the air duct resistance increases in the existing high static pressure air duct machine, because most of the motor speed has been set at the factory, it cannot be adjusted on site, and the actual static pressure of the unit may not meet the design static pressure , resulting in air volume attenuation and performance attenuation. Therefore, the designer of the present invention has designed a static pressure self-regulating control method, device and air conditioner, which can adjust the air duct resistance in real time, so that the actual static pressure of the unit is equivalent to the designed static pressure...

Abstract

Embodiments of the present invention provide a static pressure self-regulating control method, device and air conditioner, which relate to the technical field of air conditioning. The static pressure self-regulating control method includes: obtaining the actual static pressure value of the unit of the air duct machine. The change data is obtained according to the actual static pressure value and the preset static pressure value. Adjust the opening of the air valve in the air duct of the air duct machine according to the change data, so that the actual static pressure value of the unit of the air duct machine is equal to the preset static pressure value. The static pressure self-regulating control method, device, and air conditioner automatically adjust the air valve opening by detecting the actual static pressure value in real time, according to the change data between the actual static pressure value and the preset static pressure value, and feedback the air valve opening. Correction, reasonable adjustment of air valve opening, high adjustment accuracy, so that the actual static pressure is always equal to the design static pressure, realizes self-adjustment of unit static pressure, and avoids air volume and performance attenuation. In addition, cleaning prompts can be given according to the number of static pressure adjustments.

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...
