Traduction de «coefficient de transfert de chaleur » (Français → Anglais) :

‘bin-specific coefficient of performance’ (COPbin(Tj)) or ‘bin-specific primary energy ratio’ (PERbin(Tj)) means the coefficient of performance of the heat pump space heater or heat pump combination heater using electricity, or primary energy ratio of the heat pump space heater or heat pump combination heater using fuel specific for every bin in a season, derived from the part load for heating, declared capacity for heating and declared coefficient of performance for specified bins and calculated for other bins by interpolation or extrapolation, corrected where necessary by the degradation coefficient.

‘active mode coefficient of performance’ (SCOPon) or ‘active mode primary energy ratio’ (SPERon) means the average coefficient of performance of the heat pump space heater or heat pump combination heater using electricity in active mode, or the average primary energy ratio of the heat pump space heater or heat pump combination heater using fuels in active mode for the designated heating season.

‘seasonal coefficient of performance’ (SCOP) or ‘seasonal primary energy ratio’ (SPER) is the overall coefficient of performance of a heat pump space heater or heat pump combination heater using electricity or the overall primary energy ratio of a heat pump space heater or heat pump combination heater using fuels, representative of the designated heating season, calculated as the reference annual heating demand divided by the annual energy consumption.

The seasonal space heating energy efficiency ηs shall be calculated as the seasonal coefficient of performance SCOP divided by the conversion coefficient CC or the seasonal primary energy ratio SPER, corrected by contributions accounting for temperature controls and, for water-/brine-to-water heat pump space heaters and heat pump combination heaters, the electricity consumption of one or more ground water pumps.

It is our opinion, however, that the MAPLE reactor project should be reinstated and that sole technical difficulty be tackled by a group of people involving not only AECL but also those from outside this company, maybe some other organizations, including universities, where we have, over the last few years, made very powerful modifications to transport theory, nuclear reactor calculations, fluid flow, and heat transfer.

This idea of the shutting down of the Gulf Stream current reducing that heat transfer — in fact, that is the famous mechanism by which you get the scenario in the movie The Day After Tomorrow and the rapid cooling of the northern hemisphere —is considered by the IPCC to be unlikely to happen within the next 100 years.
