<p>This research work examines rotating Sutterby water-based MWCNTs + MoS₂/hybrid nanofluid flow on a stretching surface in solar heating, ventilation and air-conditioning (HAVC). The work suggests the integration of solar thermal energy into industrial phenomena by using thermal radiation, Joule heating and heat source/sink behavior along with thermal dissipative effects. The governing equations have solved though bvp4c approach in dimensionless form. The work reveals that linear velocity profiles have deteriorated with progression in magnetic factor, Deborah number, Reynolds number for both MWCNTs/nanofluid and MWCNTs-MoS₂/hybrid nanofluid flow, while tangential velocity profiles have augmented in this phenomenon. Thermal profiles have augmented with surge in magnetic factor, Eckert number, heat source factor and radiation factor for both MWCNTs/nanofluid and MWCNTs-MoS₂/hybrid nanofluid. A comparison has been made in this study, showing strong alignment between the present findings and previously recognized results, thereby confirming the reliability of the current outcomes. The MWCNTs-MoS₂/hybrid nanofluid, with its higher heat absorption and radiation interaction (especially at Rd = 0.5), is more efficient for climate control boosting the overall performance, responsiveness and sustainability of solar-powered HVAC systems, making it more reliable and energy-efficient in both residential and commercial settings.</p>
