Trnsys model type 3258 software#
Models are constructed in such a way that users can modify existing components or write their own, extending the capabilities of the environment.Īfter 35 years of commercial availability, TRNSYS continues to be a flexible, component-based software package that accommodates the ever-changing needs of both researchers and practitioners in the energy simulation community.
The standard library includes approximately 150 models ranging from pumps to multizone buildings, wind turbines to electrolyzers, weather data processors to economics routines, and basic HVAC equipment to cutting edge emerging technologies. The second part of TRNSYS is an extensive library of components, each of which models the performance of one part of the system. The kernel also provides utilities that (among other things) determine thermophysical properties, invert matrices, perform linear regressions, and interpolate external data files. The first is an engine (called the kernel) that reads and processes the input file, iteratively solves the system, determines convergence, and plots system variables. While the vast majority of simulations are focused on assessing the performance of thermal and electrical energy systems, TRNSYS can equally well be used to model other dynamic systems such as traffic flow, or biological processes. Simulation has been repeated for Miami and Houston in order to evaluate the effect of the different solar radiations on the system requirements.TRNSYS (pronounced 'tran-sis') is an extremely flexible graphically based software environment used to simulate the behavior of transient systems. Monitoring data and available electricity bills of the building have been employed to calibrate the building and geothermal air conditioning system simulation. The performance of the geothermal system has been monitored for 3 weeks. The building has been equipped with two geothermal heat pump units and a vertical closed loop system. The commercial building is located in Pensacola of Florida and is served by grid power. The solar collector loop, building, and geothermal air conditioning system are modeled using TRNSYS with the required input for the ORC system derived from the previous study. In this paper, the system requirements needed to maintain the electricity demand of a commercial building have been compared for the 11 suggested fluids. In the authors' previous work, 11 fluids have been suggested to be employed in solar ORCs that use low-temperature or medium-temperature solar collectors. The objective of this paper is to determine the optimal solar collector type and temperature of a building-scale power generation system employing solar organic Rankine cycle (ORC) engine for a geothermal air-conditioned net zero-energy building (NZEB) in a hot and humid climate.
