The main components of the TRNSYS model are Type 88 (cooling load estimation) and Type 300 (new PCTSU component), accompanied by other additional components. A refrigeration system for a typical refrigerated van is modelled and simulations are performed with climatic data from four different locations. The advantage of this refrigeration system compared to a conventional system is that it consumes less energy and produces significantly lower greenhouse gas emissions. The PCTSU is charged by an off-vehicle refrigeration unit and the PCM provides cooling when discharging and the cooling released is utilized to cool down the refrigerated space. Abstract: This paper presents a new TRNSYS model of a refrigeration system incorporating phase change material (PCM) for mobile transport. The phase change material with the lowest melting temperature should be selected.A mobile refrigeration system incorporating PCM and an off-peak electric driven refrigeration unit is feasible.The temperature in the refrigerated space can be predicted using this TRNSYS model under various conditions.A TRNSYS component of a phase change thermal storage unit was created and linked to other components from TRNSYS library.A mobile refrigeration system incorporating phase change thermal storage was simulated using TRNSYS.Their modeling does not aim a simulation of the real transfer process. A rst approach for the simulation of PCM walls using TRNSYS lies in the work of 11.

The numeric routines of TRNSYS are based on standardized calculation methods (including DIN EN ISO 13791 and DIN EN ISO 13792). in summer for free-cooling), requiring a modular simulation tool structure like TRNSYS. new TRNSYS type for the simulation of external building walls containing PCM. It is supplemented by active components and individually programmed inputs. For that purpose, a new TRNSYS Type, named Type 260, is developed to model. The building model also takes into account the building structure (geometry, characteristics of component and assemblies, weather data), the utilisation as well as requirement and load profiles. Comparison of different sun protection and shading devices including their control TRNSYS (TRaNsient SYstem Simulation) is a modular simulation program that allows the modelling of various energy systems, including HVAC analysis, multi-zone airflow analyses, electric power simulation, solar design, building thermal performance, analysis of control schemes, etc.Effect of additional thermal storage (sensitive/latent) (e.g., PCM).Switching criteria for control circuits.Periods with actual values above or below specified setpoints.Influence of building physics and constructional characteristics of the building envelope.support planning processes as well as R&D tasks and answer important questions, such as: Weather and radiation data as well as their influence on the zones and individual components of the building.Energy flows and balances between neighboring zones.controller cycling, Fernando Varela Diez.
