Solar Heating and Cooling of Buildings: Status and Perspectives (2014)

Submitted by Francesco Gattiglio on January 15, 2015

This presentation, made by Prof. Paul Kohlenbach of the Beuth University of Applied Sciences of Berlin, illustrates the status and perspectives of solar thermal heating and cooling of buildings in Germany. The presentation was made at the Mexican-German Chamber of Commerce on September 2014.  

China: First Chinese Solar Cooling Conference to Take Place in Shanghai in March

Submitted by Baerbel Epp on January 5, 2015
SHC ConferenceThis spring, a major event for solar cooling is going to take place in Shanghai: From 23 to 27 March 2015, the IEA Solar Heating and Cooling Programme and the Shanghai Jiao Tong University (SJTU) will jointly organise a Solar Cooling Week in the city. The week is going to start off with two Task meetings and end with the two-day Solar Cooling Conference (SCC). The SCC will take place for the very first time, be open to the public and include technical site visits on 26 March 2015, as well as a full-day conference with plenary and parallel sessions on 27 March 2015.

France: Promising Monitoring Results of Solar-Cooling Hybrid Strategy

Submitted by Baerbel Epp on November 5, 2014
Hybrid Solar Cooling ConceptDuring the Task 48 meeting in Garching, Germany, at the end of September 2014, Daniel Mugnier, Head of Task 48 of the IEA Solar Heating and Cooling programme, presented the monitoring results of a promising demonstration project which integrates solar cooling technology into an existing building cluster. Engineered by Tecsol, the system has been supplying energy to two buildings housing offices and flats in Montpellier, in the south of France, since May 2012. The special characteristic of the system owned by the SERM (Société d’Équipement de la Région Montpelliéraine) is a hybrid mode in which the 240 m2 field with double-glazed collectors supplies heat to a single-effect lithium-bromide absorption chiller in summer, as well as domestic hot water to the block of flats all year round. During the main cooling season in July and August, the electrical coefficient of performance (COP) showed a very high average of 12, while the measured thermal COP during the same period was, on average, 0.6.

Sweden: Novel Solar Cooling Installation Boasts Average Electrical COP of 10.6

Submitted by Baerbel Epp on October 28, 2014
ConferenceThe first large-scale system which incorporates the newly developed CoolStore chiller by Swedish company ClimateWell was commissioned in June 2014 and has since been operating flawlessly at Swedish coffee producer Löfbergs in Karlstad, Sweden. In the middle of October, ClimateWell organised a mini-conference at Löfbergs in order to showcase the installation and its first monitoring results. The measurements taken between 11 and 25 July showed an average electrical coefficient of performance (COPel) of 10.6. This is more than twice as much as for a conventional electric vapour compression system, which has a COPel of between 2 and 5. The highest COP measured at the demonstration plant was 12.

Overview of Solar Thermal Process Heat & Cooling in India (2012)

Submitted by Raquel Ponte Costa on October 2, 2014

This presentation was given by Dr. A.K. Singhal of the Indian Ministry of New & Renewable Energy at the 3rd Indo-German Energy Symposium in Delhi in May 2012.  The speaker provides a detailed overview of the various solar thermal technologies already available or still under development in India.  The presentation focuses on Solar Water Heating (SWH), Solar Air Heating, Process Heat and Solar Cooling.   SHW is well developed in India and in 2012 5.10 million m² of collectors had already been installed, with the objective to reach 18.7 million by 2022.

USA: S.O.L.I.D. Operates 3.4 MWth Cooling System as ESCO in Arizona

Submitted by Baerbel Epp on August 29, 2014
Desert Mountain High SchoolIt is an ideal location for solar cooling use: Scottsdale, a US city in the Greater Phoenix area in Arizona enjoys an average of 312 days of sunshine every year. Between May and September, temperatures rise above 38°C and can even reach 46°C on a hot day. This is where in July 2011, Austrian company S.O.L.I.D has started to plan a solar cooling system for Scottsdale’s Desert Mountain High School (DMHS) of 2,600 students. Three years later, the 3.4 MWth (4,865 m² of collector area) system went into operation and is now supplying heat to a single-effect lithium bromide absorption chiller with a cooling capacity of 1,750 kW. The solar cooling installation at the DMHS is currently the largest of its kind in the world, having surpassed the 2.7 MWth solar thermal capacity (3,900 m²) of another S.O.L.I.D system at the United World College (UWC) in Singapore.

South Africa: Fresnel Collectors Keep It Cool in MTN’s Server Rooms

Submitted by Baerbel Epp on August 28, 2014
Industrial SolarSince June 2014, a Fresnel collector field with 242 kWth has been feeding into the district cooling system of the MTN Group at its headquarters in Johannesburg, South Africa. MTN, which has more than 200 million customers, as well as subsidiaries in 22 countries across Africa and the Middle East, is one of the leading mobile operators in South Africa – and it is aware of the impact of global warming. “We continuously explore ways in which we can lessen the impact of our operations on the environment. This initiative will not only reduce our carbon footprint but it will substantially reduce our electricity consumption, which will release additional capacity for the national grid,” MTN’s CEO, Zunaid Bulbulia, was quoted as saying in a press release from 17 July 2014. The concentrating solar thermal plant powers the double-effect absorption chiller whose cooling capacity of 330 kW keeps temperatures low in the data centre at MTN’s head office.
