Unglazed Solar Collectors in Heat Pump Systems: Measurement, Simulation and Dimensioning

Submitted by Raquel Ponte Costa on January 26, 2012

This is a paper presented by a group of German researchers during EUROSUN 2008 International Congress on Heating, Cooling and Buildings held in Lisbon, Portugal. Addressing the use of heat pump systems with boreholes together with solar thermal collectors, their project - „Unglazed Solar Collectors in Heat Pump Systems: System Concept and Dimensioning” – is linked with Task 44 of the International Energy Agency’s Solar Heating and Cooling Programme.

Overview on Solar Thermal Plus Heat Pumps Systems and Review of Monitoring Results (2011)

Submitted by Raquel Ponte Costa on January 16, 2012

The target of the present paper is to give an overview on commercially available Solar Thermal and Heat Pump Systems (SAHPS) and a review on available monitoring results of these integrated systems. It is the fruit of the research of German, Italian and Austrian specialists in the framework of IEA’s Solar Heating and Cooling Programme.

Integrated Unglazed Solar Panel Development (2010)

Submitted by Raquel Ponte Costa on November 24, 2011

This is a presentation of the research done by the Environmental Energy Solutions Ltd. for the development and testing of their prototype solar heat system. The particularities consisted in the large, low cost solar collector integrated into the roof or wall cladding system and its integrated water sourced heat pump and thermal storage system. A prototype was installed on a house in Wellington, providing year-round performance data. This report was done with the support of the New Zealand Energy Efficiency and Conservation Authority.

Case Study: Dairy Farmers Milk Free Energy (2009)

Submitted by Raquel Ponte Costa on November 7, 2011

This case study is the result of a partnership between New Zealand’s Energy Efficiency and Conservation Authority (EECA), the country’s dairy farmers and technical experts, showing the benefits of solar water heating and waste heat recovery systems used to reduce energy costs.

A Guide to Buying Solar Water Heating (2009)

Submitted by Raquel Ponte Costa on October 28, 2011

Because of the climatic conditions of New Zealand and the positive impact of solar water heating technologies the country’s authorities encourage the use of this type of installations. This resulted in the issuing of a free guide by the country’s Energy Efficiency and Conservation Authority (EECA).

Overall System Performance Modeling: Solar thermal Cooling/Heating of the IW (2006)

Submitted by Raquel Ponte Costa on February 8, 2010

The Advanced Building Systems Integration Consortium (ABSIC) is an industry-university partnership aimed at researching on possibilities to improve building and systems' efficiency.

This presentation goes through a specific project with a twofold objective: design a more efficient solar thermal system and improve the efficiency of existing systems, based on a given building heating and cooling demands.

Results showed that the performance of the systems can be improved up to 27% in winter (around 3MWh) and 49.2% in summer (around 7MWh).

 

Optimised Design of Hot Water Storage in Solar Thermal Cooling Facilities (2008)

Submitted by Hans Craen on August 3, 2009

This document from 2008 looks into the efficiency of the design of hot water storage in solar thermal cooling facilities in single family buildings. Solar thermal installations, and in particular oversized facility elements, could result in higher costs and a lower than anticipated performance.

Overview of Solar Thermal Technologies (1999)

Submitted by Raquel Ponte Costa on July 29, 2009

This document, from 1999, provides an overview of key solar thermal applications - parabolic troughs, power towers and dish/engine systems - their characteristics, the kind of application they are best suited for, system performance, technologic comparison, together with a cost vs. value analysis.
