Dynamic testing of systems – Use of TRNSYS as an approach for parameter identification [PDF]

Solar Energy, 2012
AbstractDynamic testing of solar thermal systems is presently defined by ISO 9459-5:2007 [1]. The testing methodology is clearly defined in the standard. Presently, testing laboratories use DST program [3], a closed source program, for identification of parameters, which is based on a model described in reference [4]. This makes difficult to understand

Techno‐Economic and Climate‐Resolved Assessment of Solar LiBr/H2O Absorption Cooling for the Iraqi Agricultural Cold Chain

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
This study assesses a solar‐driven LiBr/H2O absorption cooling system designed to reduce post‐harvest losses in the Iraqi agricultural cold chain through the primary cooling of vegetables. The proposed system combines evacuated‐tube solar collectors, a stratified thermal storage tank, a natural‐gas‐fired auxiliary boiler, and a single‐effect absorption

Modeling of HVAC Systems for Fault Diagnosis

IEEE Access, 2020
Analytical model based fault diagnosis method is seldom adopted for heating, ventilating and air conditioning (HVAC) systems as it is rather difficult to establish and verify an explicit model for HVAC systems.
