Air preheating calculation

Air preheating calculation

Quick calculation for sizing the preheating coil. Necessary heat to be given to the air (see legal regulations) before being released into an environment

The calculation of the heat necessary to supply the air before being released into a specific environment is a fundamental aspect in the field of thermal engineering and heating, ventilation and air conditioning (HVAC) systems. This process is essential to ensure thermal comfort, safety and energy efficiency in buildings, industries and a wide range of applications.

The air that is introduced into an internal environment may require a specific amount of heat to reach the desired temperature and maintain optimal comfort or process conditions, all in compliance with current legislation. This calculation is influenced by variables such as intake temperature, outside temperature, amount of air and other specific environmental conditions.

This program was created by Itieffe with the aim of providing users with an in-depth understanding of the theoretical concepts and practical methodologies needed to calculate the heat needed to be supplied to the air before release in various contexts.

Mastering the calculation of heat requirements for inlet air is crucial for engineers, plant designers, industrial operators and all those responsible for controlling environmental conditions. Knowing this skill will not only help ensure occupant comfort, but also improve the energy efficiency and sustainability of built environments.

With this program, we will guide you through the process of calculating the heat required for inlet air in various contexts, providing you with the knowledge and tools needed to successfully tackle this technical challenge.

Quick calculation for the sizing of the preheating coil.

Heat necessary to give to the air before placing it in an environment (see legal regulations).

Instructions

How to proceed:

set the outlet temperature from the coil (delivery);

enter the inlet (outdoor) air temperature;

indicate how much air is treated in m³ / h;

view the results expressed in various units of measurement. 

In our example, to bring 3.000 m³ / h of fresh air from a temperature of 0 ° C to 18 ° C, 18.2 kW are needed (or see other units of measurement)
