The life cycle cost of standalone solar air-water heat pumps for Australian homes

To combat increasing electricity prices due to the high operating costs of conventional reverse cycle air-airheat pumps (RC-AA-HP), they can be powered by standalone PV systems as a radical demand side energy management solution. However, the heavy power consumption of their compressors necessitates very large...

A simulation, optimization and economic analysis of solar standalone reverse cycle air conditioning system for typical Australian homes

The rising penetration of vapor compression air conditioning systems in Australian dwellings has raised the peak power demand. Consequently, the electrical infrastructure requires significant, costly upgrades that is invariably passed on to all end-users. Electricity network charges account for about half the cost of an...

Comparison of mains versus standalone PV electricity to power a residential standalone solar absorption chiller in Australia

This study compares the cost of operating the auxiliary components of an optimised standalone hot water fired absorption chiller, using mains grid electricity and an optimised standalone photovoltaic system. The cheaper source was further compared with using mains electricity to operate a conventional reverse cycle...
Annual Report

Optimization of standalone solar heat fired absorption chiller for typical Australian homes

The increased penetration of residential air-conditioners (AC); specifically vapor compression types, is regarded as one of the foremost causes of a dramatic rise in critical peak electricity demands requiring corresponding upgrades of electricity infrastructures. These upgrades requires heavy investments, consequently, driving up electricity prices. Solar...

Airflow and temperature modelling of sustainable buildings at the design stage can prevent unintended consequences of passive features

This paper demonstrates that the integration of passive features during the design/construction of sustainable buildings requires thorough modelling at the design stage as some features may have unintended consequences resulting in occupant dissatisfaction, and resulting in the building using more energy to maintain comfort.
