Commercial Heat Pump Modelling

Technical

Project description:

EnergyAE has been heavily involved in commercial & industrial heat pump modelling for the new VEU Part 44 & ESS IHEAB incentive schemes. To date, EnergyAE has helped companies such as Emerald Energy, Eco Alliance, Quantum Energy Technologies and Optitech successfully register their produces on the ESC Registry. EnergyAE handles everything from testing, to documentation review, to final submission on the ESC registry, and of course taking care of any auditing enquiries to ensure the product slides into the register smoothly.

The computational effort in this scheme is much greater than for residential schemes, since the load size needs to be determined to a tight accuracy in order to maximise certificate returns. In contrast, residential schemes use either small or medium load size, which is relatively much easier to compute. Additionally, commercial schemes allow the user to define a different simulation load size in each climate zone to better reflect the relative performance in different climates. This entails running 10-20 simulations per product, per climate zone, in order to achieve optimal certificate returns. EnergyAE has created an efficient simulation platform for these calculations, making the process highly cost effective for our clients in light of the amount of administrative work involved.

We have some interest from companies offering larger capacity heat pump water heating solutions with a range of heat pump and tank configurations which will deliver large quantities of thermal heat for commercial & industrial processes such as multi-residential buildings, apartments, schools, hospitals and more. Part of the challenge for larger scale products has been to obtain testing according to the EN 14511 standard which is used to define a map of performance across a range of conditions. Test laboratories have limited space for thermal storage tanks up to approximately 700L, thus with EN 14511 the heat pump is tested across a range of distinct testing points, to cover the wide range of water temperatures.

We can help with any stage of the process, from arranging product testing, compiling documentation, running TRNSYS simulations and scheme registration. Get in touch with EnergyAE if you would like any assistance.
