To breathe clean and fresh air, it’s important to understand the concept of Air Changes Per Hour (ACH). Calculating ACH helps ensure your space has proper ventilation, which is key to maintaining a healthy and safe indoor environment. If you're looking to improve your current ventilation system for better air quality, knowing how to calculate ACH is essential. It allows you to measure how often the air in a room is replaced each hour, helping you achieve the right balance of airflow.
With this information, you can make informed decisions about your HVAC (Heating, Ventilation, and Air Conditioning) system to boost its performance and efficiency. Whether it’s for a home, office, or healthcare facility like a hospital or laboratory, calculating ACH accurately is crucial. In this blog, we’ll explain what ACH is, why it matters, and how to calculate it using a simple formula. We’ll also provide an example and list the tools you’ll need to do the calculation. By understanding ACH, you’ll be better equipped to maintain air quality and create a healthier, more comfortable environment.
