Measurement Engineering for Air Conditioning and Ventilation - 2

2 Air conditioning and ventilation engineering is a complicated and multifaceted field – You know that as well as we do. Highly diverse tasks such as planning, initial operation, approval and service with different interfaces and high demands on energy efficiency, hygiene and Indoor Air Quality all have to function in harmony. Technical requirements are high. Low energy consumption, high operational safety, long-term availability, – at the same time, it must be possible to regulate air conditioning and ventilation in the different rooms individually and in real time. Testo has the...
