Recent information on CFC's and their impact on the environment has created shockwaves of concern for those who are relying on these products in various applications and a thermal energy storage system can be considered as a useful tool to reduce the initial refrigerant charge by means of minimising the number of refrigeration machinery. A conventional HVAC stand alone ice storage installation may yield capital cost savings through a reduction in refrigeration capacity and possible inherent environmental benefits to be gained from load shifting of electrical energy.
For its new building in Mons, the RTBF (Radio and Television organism of the Belgian French Community) decided, with the help of the Walloon Region, to design several equipments with special techniques characterised by a rational and economical use of energy : primary and noble (electricity) energies and reduced use of CFC.
Modern refrigeration technology including absorption refrigeration has coexisted with the more standard type of vapour compression systems ever since the beginning of refrigeration. Absorption refrigeration mainly requires a heat source to drive its cooling cycle. Only in the USA and Japan is absorption refrigeration widespread in the market, a market tendency of the last decades. Concerns regarding the Global Warming Potential and the more recently defined Thermal Equivalent Warming Impact (TEWI) is an opportunity to further explore the applications of absorption refrigeration.
The following notes were produced "on line", during the conference. A minimum of corrections and additions were a posteriori introduced, in order to make the text readable. But no attempt was made to "soften" the comments. Such a report should , in no case, be considered as exhaustive, neither reflecting any consensus. It is nothing more than a set of subjective impressions collected by the author, along the nine previous technical sessions, after having read the corresponding reports (references 1 to 9).
The potential for evaporative cooling to meet Turkey’s growing cooling demand is investigated based on thermodynamics and human comfort. Weather and population data for 51 locations in Turkey were analyzed to estimate for each location the potential annua
A simplified method was investigated for estimating the dynamic pressure tangential to an opening (Pt) with Irwin’s surface wind sensor. The wind velocity measured by this sensor was broadly consistent with the value measured by a hot-wire anemometer. Mor
The solar façade of the FIAT Research Center (CRF) was realized recently near Turin in Italy, under cooperation between CRF and Politecnico di Milano. The photovoltaic elements, that has a total power of 19.5 kWp, produces electric energy, while the force
