... of space heating and water heating systems is critical, and it requires energy-efficient and feasible solutions rather than electric coil heating. This study proposes a heat recovery-enabled heat pump technology (i.e., variable refrigerant flow with heat recovery (VRF-HR)) for space heating and domestic...

... Abstract To solve the problem of low thermal efficiency of the organic Rankine cycle (ORC) and to enhance the coefficient of performance (COP) of ejector refrigeration cycle, an ORC combined with an ejector heat pump-based combined cooling, heat and power system using a zeotropic working fluid...

... Abstract This paper presents an experimental apparatus designed and built to facilitate the study of solar-assisted heat pump (SAHP) systems using the hardware-in-loop methodology. The apparatus includes an 11.6kW capacity water-to-water heat pump, a 409L thermal storage tank, a 288L domestic...
