Best Practices im HLK-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, latente und Gesamtwärme

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.

Air Change Cfm Calculator

The rate at which air is exchanged (in the premises) represents another method of measuring ventilation capacity & effectiveness. Air exchange rate is typically expressed in Air Changes per Hour – “ACH”. Air changes per hour can be estimated by determining the total air supplied to, and removed from, the premises “total air exchange” or the outdoor (fresh) air supplied to, and removed from, the premises “outdoor air exchange”. We invite you to experience how this calculator can transform your workflow. Whether you’re specifying a new system, troubleshooting an existing installation, or teaching the next generation of HVAC professionals, this tool was built with your needs in mind.
