“…The difference between the heat delivered by the PV/T collector and the heat extracted from the DHW-TST, either for consumption or due to thermal losses, is provided by the backup system which consumed 1251 kWh of electricity. Overall, the solar DHW system performed well, with average solar fraction values similar to those found in Santbergen et al (2010) and Silva and Fernandes (2010). However, low insolation forces the system to use backup power, which reduces the solar fraction considerably since the backup system uses a simple submersible electric heating element.…”

“…According to a study by Silva and Fernandes (2010), to match the performance of their sheet and tube PV/T setup with PV modules and solar collectors would require an additional 60% of installation area. Hence, PV/T collectors are well suited for densely populated urban areas where roof space is scarce.…”

“…Several simulation environments exist to facilitate these modelling efforts, namely TRNSYS (Kalogirou, 2001;Kalogirou and Tripanagnostopoulos, 2006;Zondag et al, 2003), MATLAB/SIMULINK (Silva and Fernandes, 2010), EES (Charalambous et al, 2011) and ESP-r (Cartmell et al, 2004). Among these, we have identified MATLAB/SIMULINK as incorporating the necessary features for the implementation of the proposed trigeneration system model.…”

A solar trigeneration system, based on photovoltaic-thermal (PV/T) collectors, photovoltaic (PV) modules and a heat pump unit for heating and cooling, is modelled to forecast the thermal and electric yields of the system. The aim of the trigeneration system is to provide enough electricity, domestic hot water (DHW), heating and cooling power to meet the typical demand of an urban single family dwelling with limited roof area and allow the household to achieve a positive net energy status. The PV/T collectors and PV modules provide the electricity while the former also powers the DHW component of the trigeneration system. The heating and cooling components rely on a vapour compression cycle heat pump unit powered by electricity. In Fong et al. (2010), solar-powered electric compression refrigeration was found to have the most energy saving potential in subtropical climates. Thus, a heat pump based cooling system is a cost effective solution for residential applications in Lisbon, Portugal. Thus, according to the dwelling's location, construction details and energy demand patterns, the model computes the system's net results by comparing the dwelling demand with the trigeneration system supply. The paper presents a breakdown of the proposed trigeneration system model and describes each component briefly. Preliminary results produced by the model are presented and analysed in order to identify possible ways of improving the overall system performance. IntroductionA trigeneration system is capable of simultaneously generating electricity, heat and cooling power from a single power source. Such a system uses complementary processes to convert the by-products of the main energy conversion and obtain forms of energy which are in line with demand. For instance, a gas-powered turbine driving an electrical generator produces electrical energy and waste heat. The waste heat can be used to produce hot water and power an absorption chiller. The same concept can be applied in solar power plants. Solar radiation is harnessed and converted to heat used to power a turbine which then drives an electrical generator, producing electricity. Heat is an evident by-product of this conversion and can be used for the aforementioned trigeneration system. Also, solar collectors and photovoltaic modules can be used to harness solar energy and convert it to heat and electricity, respectively, which may be used to power several cooling technologies (Fong et al., 2010, Immovilli et al., 2008. The aim of this article is to demonstrate the potential of a solar trigeneration system for the residential sector by describing a model, the methodology that led to that model and analysing a set of preliminary results. Solar Trigeneration System for the residential sectorA turbine-based solar trigeneration system is not suitable for the residential sector due to, among other concerns, scale, size, power rating, initial cost and maintenance. Instead, a solar trigeneration system developed specifically for the residential sector can be envisaged b...

The aim of the present work is the development of a predictive mathematical model for the analysis and optimization of energy systems used to control the environment microclimate in industrial plants. This model provides not only the evaluation of the optimal configuration on the basis of different process parameters in the existing environments, but also the analysis and the prediction of the energy consumption of a plant during the design phase. The model describes the thermodynamics of conditioning processes and allows the evaluation of the influence of design variables and of hourly averaged weather conditions on energy consumption. The model is developed both in TRNSYS-17 and C ++ programming language such that it can also be used under MATLAB computing environment. The results obtained with the two models are compared under different climatic conditions in terms of heating/cooling and humidification/dehumidification energy consumption, thus assessing the accuracy of both models. The results obtained by using different set-point conditions under different climatic zones are also presented.
