Maximising Heat Pump Efficiency
Heat pumps have seen a significant rise in popularity in recent years – and rightly so, as they are the technology of choice for making buildings more sustainable. However, implementing a heat pump isn’t a simple plug-and-play solution. Proper hydraulic and control-strategic integration is crucial to achieve maximum efficiency and extend the system’s lifetime. Factors such as delta-T monitoring, start-stop behaviour, storage tank sizing, return temperature control, and more must be carefully considered during the HVAC design process.
In this webinar, we’ll cover best practices for designing HVAC systems with heat pumps, exploring various system concepts and design templates. Our HVAC Expert, Etienne Corish, will guide you through the following topics, with a live Q&A at the end:
-
Heat pump sizing
-
Staged vs. VSD compressors
-
Heat pump control (delta-T control, return temperature control)
-
Storage tank sizing (anti-cycling, peak shaving, anti-frost cycle)
-
Heat pump/boiler hybrid (for low and high temperatures)
-
Full electric (for low and high temperatures, booster heat pump, ammonia/propane/CO2)

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.

Designing Changeover Systems
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 will cover the do's and don'ts of changeover systems and how to size them correctly.
