Physical Modeling for Thermal Proposal Validation (TES) in Lima Offices with Air Conditioning

Climate change adaptation measures are demanding the use of technologies that promote energy saving. The search for thermal comfort has encouraged the use of technologies such as the TES tank (Tank Energy System). This article presents the validation of the results obtained in the CFD simulation of a TES tank, through an evaluation of the model at 1/25 scale, to corroborate the thermal resistance of the tank whit thermal conductivity of 1.63 W/m. °K and expanded polystyrene with thermal conductivity of 0.036 W/m°K for both the walls and the lid. The circular TES tank designed guarantees, in addition to adequate thermal resistance, impermeability and durability so that it can function correctly during temperature measurements. In the model, the thermal resistance of the tank was corroborated, by obtaining an increase in the temperature of the temperature of the water in 8 hours of 7 °C (12.6 °F). That is, from 5.9 °C (42.62 °F) to 12.9 °C (55.22 °F), which does not exceed 15 °C (59 °F), the recommended value for its viability.
