“THE DISTRICT HEATING AND COOLING SCHEME IN TRITON SQUARE, CENTRAL TOKYO, IS THE LARGEST SYSTEM OF ITS KIND IN JAPAN. IT COMBINES A LARGE-SCALE HEAT STORAGE TANK AND A HIGHLY EFFICIENT HEAT RECOVERY PUMP, USING ELECTRICITY AS A POWER SOURCE. THE SCHEME IS UP TO 40% MORE EFFICIENT THAN CONVENTIONAL SYSTEMS AND HAS LED TO A 60% REDUCTION IN CO2 EMISSIONS.”

This recovered heat would have been waste heat and rejected to the atmosphere, instead is being utilized for reheat for the added cost of operating the heat recovery pump.”

REGENERACIJA vs. REKUPERACIJA

Popić dr Relja et al, Naučno tehnički rečnik, Građevinska knjiga, Beograd, 2005:
heat regenerators - toplotni regeneratori

Mihalidi A. i M, Hemijsko tehnološki rečnik, PS Grmeč, Beograd, 1994:
heat recovery - rekuperacija toplote
heat regenerator - regenerator toplote

Klaić B, Veliki rječnik stranih riječi, Zora, Zagreb, 1968:
regenerator - naprava kojom se toplina dimnih plinova iskorišćuje za pregrijevanje uzduha i gorivog plina
rekuperator topline - uređaj kojim se toplina, što izlazi s ogrjevnim plinovima, iskorišćuje za grijanje zraka koji se troši na gorenje.

Kao što se vidi iz citiranih rečnika, i jedno i drugo se koristi u slučaju toplotne energije. U konkretnom slučaju, predlažem „regeneracija“ zato što taj termin koristi i proizvođač baš takve opreme - „ALFA CLIMA“ iz Knjaževca (v. gore).
