Publication - Uncertainty in long-term Photovoltaic Yield Predictions
CETC Number 2010-122 / 2010-09-03 This report summarizes the uncertainties associated with the prediction of long-term photovoltaic (PV) yield. The report addresses mainly uncertainties facing large-scale PV developers, although some of the conclusions may also be applicable to small systems. The uncertainties facing developers include factors such as expected yield, government policies and decisions, issues related to permitting, siting and grid connection, cost, availability and ...

Publication - A new modeling approach for the study of refrigeration finned coils with CO2.
CETC Number 2010-053 / 2010-08-17 Abstract Heat exchangers are major components in refrigeration systems where they are used as evaporators or condensers. Better understanding their thermal and hydrodynamic behaviour is therefore important, in order to improve their design and maximize their performance. In this paper, a new model simultaneously accounting for the thermal and hydrodynamic behaviour of fin and tube heat exchangers working under conditions of no condensation of air ...

Publication - A new modeling procedure for circuit design and performance prediction of evaporator coils using CO2 as refrigerant
CETC Number 2010-091 / 2010-08-17 Abstract The replacement of environmentally damaging synthetic refrigerants due to their ODP or GWI potential by natural refrigerants such as CO 2 is now up in the research agenda. Moreover, current energy supply concerns make of efficiency another first priority issue to dictate new stringent design criteria for industrial and commercial equipment. Heat exchangers are the most important components in refrigeration systems where they are used as ...

Publication - CO2 as a Refrigerant in a Sobeys Supermarket
CETC Number 2010-093 / 2010-05-27 Abstract Out of concern for the environment, the Sobeys Québec inc. Corporation has built a supermarket that is innovative in terms of environmentally friendly refrigeration. The new IGA supermarket in St‑Félix‑de‑Valois is equipped with a refrigeration system that minimizes the risk of synthetic refrigerant leaks, which constitue an important source of greenhouse gas (GHG) emissions from supermarkets. Opened in May 2009, the new supermarket is among ...

Publication - Smart Grid - Activities in Canada
CETC Number 2010-087 / 2010-05-27 Smart grids are being developed in several states and provinces worldwide. Motivated by distinct policies and technical constraints, regional authorities prioritize some applications of the smart grid over others in order to meet their specific needs. Each application has a different set of economic, environmental and security impacts. Each region has its own variety of energy challenges that may be, capacity constraints, reliability or the integration ...
