Email sondh1986@ ARTICLE INFO ABSTRACT Received 07 09 2022 The factors affecting the air temperature after the condenser with auxiliary cooling using fired bricks sprinklered based on the experimental Revised 05 10 2022 investigation of the difference in air temperature before and after the Accepted 20 10 2022 condenser was investigated in this study. In order to make comments and evaluate the operating status of the equipment the best solutions can be Published 28 10 2022 given in operation maintenance equipment upgrading and energy saving. Using robust design methods reputable statistical tests are Taguchi and KEYWORDS ANOVA together with 3D modeling support software INVENTOR and numerical and statistical computing software MINITAB . From there HVAC proceed to build a condenser model experiment and process data. After Taguchi performing experiments and testing by statistical methods the optimal ANOVA model results for the room temperature field to be cooled are Optimization A1B1C1D1E1F2 position of A1 fired bricks horizontal bricks material Robust design. structure data B1 2-hole fired bricks set temperature at evaporator C1 22 time of day D1 measurement option at noon the distance between bricks E1 5cm apart F2 brick arrangement parallel is the best combination for the ability to cool the air after the condenser. The difference in air temperature before and after leaving the condenser is ΔT with the temperature before and after exiting the device being 34 65 28 55 respectively. Which the brick .
