Articles
At SIL3X, we believe that knowledge is most valuable when it is shared. While professional social networks such as LinkedIn are great for exchanging ideas, they are not always the best place for in-depth explanations, technical diagrams, or detailed analyses. That's why we created this space: to publish technical articles covering both specialized and cross-disciplinary topics, whether theoretical or highly practical. Our goal is simple: to share knowledge, with no limits other than curiosity.
Balancing flow in a hydronic network, from household heating to datacentre cooling
The sizing of a ventilation system cannot always be limited to a simplified thermal balance. This article presents TAeZoSysPro, a Modelica library developed by SIL3X to simulate thermo-aeraulic transients while taking into account the inertia of buildings, convective and radiative exchanges, as well as thermal storage phenomena.
HVAC sizing: validating thermal transients
The sizing of a ventilation system cannot always be limited to a simplified thermal balance. This article presents TAeZoSysPro, a Modelica library developed by SIL3X to simulate thermo-aeraulic transients while taking into account the inertia of buildings, convective and radiative exchanges, as well as thermal storage phenomena.
Age of air
The air renewal rate is a global indicator that does not allow for the identification of inadequately ventilated areas. Thanks to CFD simulations and the calculation of air age, it is possible to detect these dead zones and more accurately assess the actual quality of ventilation in industrial premises.
Free cooling or free chilling?
Free cooling and free chilling are two approaches to reduce the energy consumption of cooling systems by using outdoor conditions, but their operating principles and areas of application differ. This article explains their principles, their technical limitations and the criteria for selecting the appropriate method based on setpoint temperatures and the requirements of the installation.
