Research & Development

Physics-based HPWH Model

We developed a first-principles simulation of the vapour-compression refrigeration cycle in-house, in Python, built to find the design and control changes that raise system COP. It resolves each component from fundamental physics, validated against a small amount of your own internal test data, then explores the full design space you cannot reach by testing alone. Currently optimised for residential R290 integral microchannel heat pump water heaters.

• COP and capacity diagnosis: identify which component limits efficiency
• Design variant analysis: predict the impact of compressor sizing and heat exchanger geometry changes before manufacturing
• Control logic optimisation: assess the effect of setpoint, expansion valve superheat, and compressor speed schedules on COP
• Refrigerant charge optimisation: find the optimal active charge for a given system geometry
• New product pre-assessment: evaluate a proposed design before committing to tooling or physical testing

MEPS Simulation

EnergyAE runs your product through a validated simulation of the AS/NZS 5125.1 Appendix H test protocol, interprets the results, and provides design recommendations before you commit to physical testing. With Chinese laboratory retests costing tens of thousands of dollars including shipping and delays, one avoided retest covers the consulting engagement many times over.

• Simulate all three Appendix H test sequences at each of the three required ambient conditions
• Identify likely failure modes and quantify margin to the MEPS threshold before physical testing
• Recommend design or control changes to optimise first-time pass probability
• Applicable to new products and existing products being assessed for MEPS compliance

Incentive Scheme Pre-assessment

Using TRNSYS simulation against AS/NZS 4234, we model your product's predicted certificate yield before formal scheme registration. The same design and control logic that drives MEPS performance also determines incentive scheme outcomes, so this analysis covers both in a single engagement.

• Predict STC and VEEC yields for proposed or existing designs
• Identify control and design changes that improve scheme performance
• Align optimisation across MEPS and incentive scheme requirements in one pass

Collaboration

We collaborate with manufacturers, government agencies, and research institutions to advance clean energy technology. Our team has contributed to projects at leading Australian and international universities.

EnergyAE is an active member of the CS-028 Australian Standards committee, contributing to the development of standards that govern energy efficient water heating products.
