Multitran:

open cooling tower - тех. открытая градирня

closed-circuit cooling
быт.тех. циркуляционное охлаждение
тех. охлаждение по замкнутому циклу; замкнутая система охлаждения; охлаждение по замкнутой схеме

Далее описание с одного из сайтов (адрес см. ниже):
An indirect, or closed circuit cooling tower involves no direct contact of the air and the fluid, usually water or a glycol mixture, being cooled. Unlike the open cooling tower, the indirect cooling tower has two separate fluid circuits. One is an external circuit in which water is recirculated on the outside of the second circuit, which is tube bundles (closed coils) which are connected to the process for the hot fluid being cooled and returned in a closed circuit. Air is drawn through the recirculating water cascading over the outside of the hot tubes, providing evaporative cooling similar to an open cooling tower. In operation the heat flows from the internal fluid circuit, through the tube walls of the coils, to the external circuit and then by heating of the air and evaporation of some of the water, to the atmosphere. Operation of the indirect cooling towers is therefore very similar to the open cooling tower with one exception. The process fluid being cooled is contained in a "closed" circuit and is not directly exposed to the atmosphere or the recirculated external water.

Спасибо за ссылку. Можно ли назвать closed-circuit cooling tower - градирней замкнутого цикла?

[solidrain]

Лучше, наверное, "градирня с замкнутым контуром охлаждения".

Thanks

Извините за вторжение.
"closed-circuit cooling tower" - это градирня системы оборотного водоснабжения. Градирня является холодильником в закрытой системе оборотного водоснабжения производства или установки (аналогично радиатору в автомобиле).
Всем успехов.

Еще раз извините за вторжение. Я поленился прочесть текст.
Поэтому Soldarin более прав, чем я.
