New test methodologies to analyse direct expansion solar assisted heat pumps fo...
Facão, Jorge; Carvalho, M. J.Since there are not specific standards for testing direct expansion solar assisted heat pumps for domestic hot water, new testing methodologies are proposed supported by laboratory experiments. Two methodologies were developed for performance measurement: modified BIN method and long term performance prediction with a TRNSYS model validated with specific experimental conditions. The long term performance predic...
UNISOL: solar combistore evaluation and optimization
Amorim, Ricardo; Facão, Jorge; Rodrigues, João Carlos Teixeira; Carvalho, M. J.In the frame of UNISOL project, a test bench was installed to perform tests of a combistore which includes a two-way heat exchanger already submitted to a national patent application. The present work describes the main characteristics of the test bench installed and the tests performed with the objective of optimization of the configuration of the inner storage tank of the combistore (two way heat exchanger),...
The COOLSUN triple-technology approach to reach high solar fractions for space ...
Facão, Jorge; Lobato, António; Baldo, CatherineWithin the framework of the COOLSUN project a triple-technology approach to reach high solar fractions for space heating, space cooling and domestic hot water preparation is being developed. The three core components are a thermo fluid with a low environmental impact and a boiling point above 200 °C, a high efficient adsorption chiller, and an advanced controller. System simulations modelling the transient beha...

Factory Made Solar Thermal Systems - Dynamic System Testing and development of ...
Neves, Ana; Mexa, Nuno; Facão, Jorge; Gomes, José Dias; Carvalho, M. J.This paper presents first results of a project that aims at the development of new mathematical models for characterization of Solar Thermal Systems (Factory Made Systems as defined in EN 12976) that can be used in association with dynamic system testing (non intrusive test method defined in the document ISO 9459-5) and which, based on the characteristic parameters defined in the adopted models, allow determina...
