Review of the advances in solar-assisted air source heat pumps for the domestic sector

Solar assisted air source heat pump shows great potential as a promising energy-saving heating technology, which integrates solar collector and pump. It is widely considered for supplying hot water, space and/or cooling in the domestic sector. The performance of pumps can be evaluated system level by parameters such coefficient performance, seasonal factor, energy consumption, fraction well initial operating costs, component efficiencies collection thermal storage. Their performances are affected many factors configuration, components size, working fluid, conditions weather conditions. This paper presents comprehensive review on recent advances sector terms collectors, storage, defrosting method perspective areas further investigations. results this confirm that research still required to improve combined reduce cost compared with existing systems based hydrocarbon combustion. information presented beneficial researchers, small medium-sized enterprises suppling renewable technologies, engineers service workers, policy decision makers, environmental activists communities.
