Best Practices in HVAC Design
In this blog post, we’ll discuss some of the key principles and best practices in HVAC design that every engineer should know. HVAC design is an essential aspect of creating comfortable and efficient indoor environments. As an HVAC-R engineer, understanding the principles of HVAC design is crucial for designing effective, reliable, and sustainable heating, ventilation, and air conditioning systems.
Sensible, Latent, and Total Heat
Sensible heat, latent heat, and total heat are important concepts in HVAC. Sensible heat is the heat that is transferred to or from a substance without causing a change in phase. Latent heat is the heat that is transferred to or from a substance during a phase change, such as from a liquid to a gas or from a gas to a solid. Total heat is the sum of sensible heat and latent heat.
R-Value and U-Value in HVAC
R-value and U-value are two important concepts in HVAC. R-value is a measure of a material’s resistance to heat flow, while U-value is a measure of its ability to transfer heat. The higher the R-value, the better the insulation, while the lower the U-value, the better the insulation.
Calculs de débit d'eau dans le CVC
Water flow rate is an important parameter in the design and operation of HVAC systems. It is important to calculate the correct water flow rate to ensure that the system operates efficiently and effectively.
