Constant air volume conditioner and control method thereof

Abstract

The invention discloses a constant air volume conditioner and a control method thereof. According to the control method, basic reference data, related to air supply volume and obtained when an indoor fan operates at a standard operating speed Nb and an air guide reaches a maximum outlet position and a position deviating from the maximum outlet position, is preset in a storage module of the conditioner; an analytical processing module of the conditioner calls the basic reference data and acquires compensated speed of the indoor fan according to a deviation of the air guide deviating from the maximum outlet position; the analytical processing module adjusts the speed of the indoor fan according to the compensated speed. According to the constant air volume conditioner and the control method thereof, the compensated speed of the indoor fan is acquired through calling the basic reference data and according to the deviation of the air guide, the speed of the indoor fan is adjusted according to the compensated speed so as to change the air supply volume, and constant air supply volume is maintained; therefore, air supply volume stability is improved for the conditioner, and refrigerating and heating performances of the conditioner are improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioner with constant air volume and a control method thereof. Background technique [0002] With the continuous improvement of people's living standards, the use of air conditioners has become particularly popular. At the same time, the cooling and heating effects and comfort of air conditioners have gradually become the focus of attention of users. When the air conditioner is cooling or heating, the indoor wind wheel of the indoor unit runs at a constant speed, and the upper and lower air deflectors of the indoor unit swing up and down continuously or stay at a specific angle to change the air supply of the indoor unit. area and wind direction. When the upper and lower air deflectors change the air supply angle and are not at the maximum opening position, the effective flow area of ​​the air outlet of the indoor unit decreases and the air supply resistance ...

AI Technical Summary

Problems solved by technology

When the upper and lower air deflectors change the air supply angle and are not at the maximum opening position, the effective flow area of ​​the air outlet of the indoor unit decreases and the air supply resistance increases due to the shielding of the upper and lower air deflectors, which will cause indoor The air supply volume of the machine is reduced

Since the cooling and heating effect of the air conditioner is positively related to the air supply volume of the indoor unit, when the air supply volume of the indoor unit is reduced, the cooling and heating effect of the air conditioner is bound to be reduced, thereby reducing the cooling and heating speed of the air conditioner and comfort
