The latest Advancements in HVAC Technology and their Potential Benefits.

Abstract

The main objective here is to study the performance of the solar chimney in the HVAC system. The main parameters of the study will be the temperature distribution, pressure distribution, and velocity of air within the system and chimney. The flow inside the chimney will also be a core part of the study. Based on governing equations numerical simulations are performed within the system. Volumetric flow rate of the chimney is the main parameter that will demonstrate its ventilation effectiveness. From the study, the pressure contours results, it was observed clearly that for a normal conventional room when it integrated with solar chimney its pressure reduces from 3.67 Pa to 1.19 Pa and its temperature increases from 301 K to 308 K because of chimney draught effect. In the Velocity contour results, it was clearly observed that HVAC system without having solar chimney its fluid velocity is very slow as compared to the HVAC system when it is integrated with solar chimney. And also at inlet of chimney fluid enters into the chimney with wider angle due to chimney effect. Velocity remains zero due to no slip conditions at the walls.
