Waste heat air-source heat pump water heater (WH-ASHPWH) systems have been widely used to provide water heating in buildings due to their advantages of high efficiency and low environmental impact. It is important to determine reasonable operating co...
The performance of an air-source heat pump water-heater (ASHPWH) system manufactured by Kronoterm was benchmarked in this study for the application of dairy farming in Ireland. The COP of the system was calculated to be 2.27 under normal operating co...
As new energy-efficient technologies emerge, space and water heating systems are continuously evolving. The latest generation of heating, ventilation, and air conditioning (HVAC) systems in Canada and other countries is shifting away from natural gas...
As a clean energy technology, air source heat pump (ASHP) technology has garnered increasing attention nowadays; however, the sharp decline in energy efficiency under low-temperature conditions remains a significant challenge impeding their widesprea...
This study presents the design, thermodynamic modelling, and numerical optimisation of a medium-scale (100 kW) transcritical CO2 air-source heat pump water heater (ASHP-WH) intended to deliver 90 °C domestic hot water under sub-zero ambient condi...
