Glossary of terms used in our work.
Definitions:
- Air-Source Heat Pump (ASHP): A type of heat pump that extracts heat from the air to provide heating or hot water.
- Clean Energy Regulator (CER): The administrator of the Renewable Energy Target (RET), including the Small-Scale Renewable Energy Scheme (SRES).
- Coefficient of Performance (COP): The ratio of input power to thermal output, indicating the efficiency of a heat pump.
- Delta-T Heat Exchanger (DTHX): Represents the driving temperature difference between the heat exchanger and the tank, determining the degree of stratification.
- Energy Savings Certificate (ESC): The tradable certificate currency of the Energy Savings Scheme (ESS) in New South Wales.
- Energy Savings %: The percentage of energy savings of the Air-Source Heat Pump Water Heater (ASHP) or Solar Water Heater (SWH) during TRNSYS simulation compared with the reference water heater, typically an electric storage water heater.
- Energy Savings Scheme (ESS): A scheme in New South Wales encouraging energy efficiency and reducing energy consumption.
- Essential Services Commission (ESC): The Victorian administrator of the Victorian Energy Upgrades (VEU) scheme.
- Frosting Penalty (FP): A penalty for low-temperature operation caused by frosting, reducing the Coefficient of Performance (COP). Calculated based on a comparison of the COP in the low-temperature test at approximately 2°C.
- Independent Pricing and Regulatory Tribunal (IPART): The New South Wales administrator of the ESS.
- Minimum Delivery Temperature (MDT): The minimum temperature of water delivered to the load during TRNSYS simulation. Must be at least 45°C.
- Small Scale Renewable Energy Scheme (SRES): Provides Small-Scale Technology Certificates (STCs) to small-scale renewable energy installations, including Heat Pump Water Heaters (HPWHs) and Solar Water Heaters (SWHs).
- Small Scale Technology Certificate (STC): A tradable certificate representing a unit of renewable energy generation, used in SRES.
- Technical Details Sheet (TDS): Spreadsheet containing all parameters relating to TRNSYS modeling of a system.
- Stratification: The degree to which a tank is thermally layered, with different temperature zones.
- Technical Details Sheet (TDS): Spreadsheet containing all parameters relating to TRNSYS modeling of a system.
- Victorian Energy Efficiency Certificate (VEEC): A tradable certificate used in the Victorian Energy Upgrades (VEU) incentive scheme.
- Victorian Energy Upgrades (VEU): An incentive scheme promoting energy efficiency measures in Victoria.
- Zones (Climate Zones): Zones 1-5 refer to different regions of Australia from a climate perspective.
