Simulation of rooftop photovoltaic shading using TRNSYS

The shade effect of a rooftop photovoltaic (PV) collector on a roof is usually ignored in building energy simulation in Transient System Simulation (TRNSYS) software. This disregard is due to either the unavailability of a suitable shading component in the simulation software or to an...

Study of building integrated photovoltaic/thermal double-skin facade for commercial buildings in Sydney, Australia

Research activities previously performed on shorter simulation timeframe had shown that building-integrated photovoltaic/thermal double-skin façade (BIPV/T-DSF) could maintain a comfort temperature within a building, by adopting a fan-assisted ventilated air cavity in summer, and a non-ventilated air cavity during winter in order to reduce overheating...

Precipitation and buildings: estimation of the natural potential of locations to sustain indirect evaporative cooling strategies through hot seasons

Precipitation is a relevant climatic variable for building and urban design in hot climates, because of its potential to naturally mitigate heat excess in buildings and cities by evaporative cooling; and as a primary source of water to artificially reproduce this cooling mechanism, particularly in...

Reconceptualization of climate classifications and climate analysis tools to support evaporative building cooling strategies in the hot humid tropics

Evaporative Cooling (EC) is increasingly regarded as a powerful and effective method for building cooling, mitigation of Urban Heat Islands (UHI) and for urban adaptation to climate change (Kitano et al., 2011; Saneinejad et al., 2014). As this cooling technique depends on the adequate supply...

Application of internal cooled desiccant wheel in air-conditioning system

Desiccant wheel based air-conditioning systems (DWAC) include a desiccant wheel component that performs latent cooling coupled to another component, for example an indirect evaporative cooler (IEC also known as a dew point evaporative cooler), that performs the sensible cooling without adding moisture into the air...

Ground coupled photovoltaic thermal (PV/T) driven desiccant air cooling

The photovoltaic thermal (PV/T) driven desiccant air cooling process could be a good solution to the conventional air cooling cycle in terms of energy saving, where the latent cooling load would be removed adiabatically. However, problems exist where the required desiccant regeneration temperature (60oC -...

Multi-objective optimization of a solar-powered triple-effect absorption chiller for air-conditioning applications

In this paper, a detailed simulation model of a solar-powered triple-effect LiBr–H2O absorption chiller is developed to supply both cooling and heating demand of a large-scale building, aiming to reduce the fossil fuel consumption and greenhouse gas emissions in building sector. TRNSYS 17 is used...
