Abstract
The invention discloses an air cooler theoretical calculation method suitable for an air compressor under a moisture-containing working condition. The air cooler theoretical calculation method comprises the following steps that (1) dry-state air flow is converted into wet-state flow according to the humidity condition; 2) judging whether the phase state before and after air heat exchange is changed or not according to air humidity, air inlet and outlet temperature and inlet and outlet pressure; 3) correspondingly calculating the thermal load according to different working conditions of whether the condensate water is separated out in the step 2); (4) calculating the cooling medium side temperature according to the thermal load in the step (3), and determining the average logarithmic temperature difference of the air cooler; (5) arranging cooling pipe distribution according to the cooling medium flow and flow velocity requirement range, and preliminarily designing the heat exchange area; (6) the total heat transfer coefficient of the air cooler is calculated according to the pipe diameter and the pipe wall thickness of the cooling pipe selected in the step (5), and the heat exchange area initially designed in the step (5) is checked according to the design allowance and the following heat transfer equation; and 7) checking the air side pressure drop according to the operation requirements of the air cooler. According to the invention, precise design is realized.
