Itieffe is pleased to present a revolutionary program dedicated to the calculation of the air changes necessary for each type of environment. The quality of the air we breathe is a fundamental aspect for human well-being and operational efficiency in many contexts, from homes to industrial, commercial and healthcare environments. The need to ensure clean and safe air has emerged with particular urgency in recent years, with increasing attention to hygiene and the prevention of airborne diseases.

This program was designed to proactively address this challenge by offering a sophisticated and customized solution for calculating air changes. Its importance is even more evident in the current context of growing awareness of air quality and its influence on human health.

Here are some of the key features of this program:

Environmental Analysis: we start with the calculation of the dimensions of the rooms managing to obtain their volume.
Regulations and Guidelines: Local regulations and international guidelines on air quality and air exchange standards are taken into account. This ensures that the environment complies with current regulations.
Precise Calculation Algorithms: Uses formulas based on scientific data to calculate the number of air changes required to maintain optimal and safe air quality in the specific environment.

Air quality is a growing priority for people's well-being and room efficiency. This program was created to address this challenge accurately, efficiently, and cost-effectively. We are delighted to share with you this innovative solution that can significantly improve the health and comfort of people in your premises. It's time to breathe fresh, safe air, and this program is your ally to do it smart.

How to calculate the air changes in different types of environments - Quantity of air changes required per room per hour

In the design and construction of systems, increasing attention is paid to the well-being of people who frequent closed environments.

These aspects are closely linked to the healthiness of the air you breathe and it is for this reason that it becomes essential to ensure adequate thermohygrometric conditions, air changes and filtering treatments, so that the pollution inside the rooms can be considered at least acceptable (treated in other sections of the site).

The number of air changes is given by the ratio between the volume of air supplied to the environment in one hour (m³/ h) and the volume of the served area (m³).

A new section has also been inserted for the Anglo-Saxon system (British imperial system).

Normally, with 8 air changes per hour (sometimes even less), the pollution caused by the occupants is eliminated. Greater numbers of spare parts, in temperate climates, also provide for the disposal of heat and fumes (see: Cool with fresh air).

For example: if 100 2 m³ / h of air is introduced into a 000 m³ room, 20 air changes per hour were supplied to it.
