Summary:Air condensers are liable to suffer from undercooling (cooling to too low a temperature) which may entail frost damages and represents, in any case, thermo-dynamic losses. In order to prevent undercooling the working length (X) of the cooling surfaces of the air condensers (10) are controlled by shutters (28) which are associated with a drive mechanism (30) operated dependent on the temperature difference of condensate withdrawn from a first and a further row of tubes (18,20) of the air condensers, as measured by thermometers (34,36). By shutters (46) located in a gap (44) between the air condensers (10) the cooling air is enabled to recirculate (84) whereby danger of frost and undesired rising of the temperature level of condensation may be avoided and impeded, respectively. A casing (68; ) encompassing the air condensers (10) is provided with shutters (64,66) at its bottom and top and permits starting without danger of frost, likewise by means of recirculation.
