The novelty of this work includes the use of MSW composition listed for Ontario, as fuel feed to an air-Brayton cycle, as well as coupling a heat pump to it through water conduits, to carry out thermal desalination and space heating applications. Related calculations are carried out using corresponding mass, energy, entropy, and exergy balance equations of key system components, and Engineering Equation Solver (EES). The integrated heat pump utilizes R134a refrigerant and is driven by solar thermal collectors during periods when sunlight is available, and through sensible thermal energy storage otherwise. Under nominal operating conditions, an irradiance of 800 W/m<sup>2</sup> is considered, and the energy and exergy efficiencies of 37.43 % and 24.55 %, are achieved, respectively. Moreover, a coefficient of performance of 2.72 is obtained for the same operating conditions. For more location specific calculations, the solar profile for the Durham region in Ontario, Canada, is used and values are obtained as yearly averages for irradiance. This results in a variation of energy and exergy efficiencies across a diurnal operation, where they range between 52.56 % to 43.98 % and 35.67 % to 29.27 %, respectively. The thermal energy storage charging capacity ranges between 2,625 kWh to 12,985 kWh during the day, and results in a uniform discharge capacity of 6,297 kWh for periods of no sunlight where energy and exergy efficiencies are obtained to be 49.43 % and 33.3 %, respectively. The variation of the reference temperature is also considered where the exergy efficiency decreases from 24.55 % to 23.38 %, as the reference temperature increases from 296.15 K to 340 K for 800 W/m<sup>2</sup> irradiance.

Computational simulation code was used in a sensitivity analysis to identify key design characteristics. The system’s performance was assessed through extensive parametric studies, focusing on high solar radiation locations, with Lhasa serving as the case study due to its favorable environmental conditions. The findings indicate that increasing the Butane mass fraction in the dual-fluid organic Rankine cycle initially boosts evaporation rates and power output, peaking at a mass fraction of 0.2. Beyond this point, performance declines due to changes in evaporator operating modes, affecting heat transfer rates and overall system efficiency.

Increasing Evaporator 3′s temperature initially enhances power generation, peaking at 60 °C. According to meteorological data and system dynamic analysis, electricity generation in Lhasa reaches its peak during the summer months, with July contributing 12,671.53 MWh.

The hybrid nanofluid is formed with nanoparticles of Titanium oxide (TiO<sub>2</sub>) and Copper (Cu) in water as the base fluid. The governing set of equations is formulated as an extension of the Prandtl fluid model to investigate the physical effects of chemical processes, heat radiation, bioconvection, and energy dissipation. The nonlinear ordinary differential equations are derived after successfully implementing appropriate transformations on governing equations and are solved numerically via the Differential Transform Method (DTM). The graphical illustration of non-dimensional velocity, temperature, and concentration is obtained through MATLAB and discussed with proper physical justification for various terms such as magnetic parameter, chemical reaction, radiation parameter, Sherwood number, Nusselt number, and friction parameter. The outcomes are validated with a comparison of previous published work. Results reveal that hybrid nanofluids significantly enhance heat transfer efficiency compared to conventional nanofluids.
