In changeover systems, the same thermal end units or even the same hydraulic network are used for both heating and cooling purposes. This makes them attractive from an investment standpoint but significantly increases the complexity of calculations.
In this webinar, we’ll cover best practices for designing HVAC systems whilst designing changeover systems. One of our HVAC Experts will guide you through the following topics, with a live Q&A at the end:
- Why changeover?
- Different changeover configurations
- 4-pipe system vs. 2 pipe system
- Pipe and pump sizing
- Dynamic balancing
- Controls
- Expansion and pressurisation system
Whether you’re an HVAC Engineer, M&E Consultant, Installer, Design & Build Contractor, ESCO, or simply interested in the latest HVAC technologies, everyone is welcome to join!

Improving Pump Energy Savings
Replacing old pumps by new pumps can generate energy savings up to 45% simply due to improved pump and motor efficiency. However, by looking beyond the pump itself, up to 95% of pump energy savings can be achieved by also optimising pump controls, valve selection, pump (de)centralisation, and more.

Améliorer les Économies d'Énergie des Pompes
Le remplacement des anciennes pompes par des nouvelles peut générer des économies d’énergie allant jusqu’à 45 %, simplement grâce à une meilleure efficacité des pompes et des moteurs. Cependant, en regardant au-delà de la pompe elle-même, jusqu’à 95 % des économies d’énergie peuvent être réalisées en optimisant également les régulations de la pompe, la sélection des vannes, la configuration des pompes (centralisation/décentralisation), et plus encore.
