Performance and economic evaluation of a photovoltaic/thermal (PV/T)-cascade heat pump for combined cooling, heat and power in Tropical climate area

Performance analysis of a new PV/T-cascade heat pump design having 7-kW maximum cooling capacity for combined cooling, heat and power was simulated with the climate of Chiang Mai, a city in tropical area. The technique could enhance both electrical performance of PV/T module, and heat pump thermal performance for cool water (below 17oC) and hot…

Performance analysis of biomass boiler-organic Rankine cycle with assisted cascade heat pump for combined heat and power generation including exergy-costing

Performance analyses and economic evaluations based on exergy-costing of a biomass-boiler organic Rankine cycle coupled with a cascade heat pump system for combined heat and power generation were investigated. The net power outputs of the Rankine cycles were 7 and 20 kWe at the condensing and evaporating temperatures of 40 and 100oC, respectively. The heat…
