The heater connected in series with the cooling element 20 may serve for heating the cars connected to a 46 of the condenser l9. More specifically, the arlocomotive. The arrangement shown in the rangement comprises a reservoir or tank 2| for present instance includes three valves 31, 33, and cooling medium, preferably water, connected to 39. With the valves, 38 and 3!! closed and the the outlet of the cooling element 2|] by a convalve 31 open, all of the liquid discharged by the 'duit 22 to receive heated cooling medium dispump 24 is forced directly into the heat excharged from the cooling element 20.

Another part 01 the air is conducted through a conduit 3 .to be discharged therefrom to a consumer such as an air heater, not shown; As the cooling medium for eflec'ting condensation in the turbine condenser is contained in a closed system, loss of cooling medium is eliminated which is a great advantage, especially when the ary rangement is to be used in connection with vehicles. The provision of a water-cooled, surface-type turbine condenser as pointed out above reduces considerably the dimensions of such condensers, an important point to be considered especially in locomotive design. The surface-type heat exchanger 25 is also of comparatively small dimensions in view oi the good heat transfer between water and air.

desirable manner.
From the standpoint of thermal economy it is permissible to provide a condenser either with a small vacuum orwith no vacuum at all since boilers are now available for generating steam or other elastic fluid of high pressure and a high degree of superheat. In some cases it is advantageous to circulate the cooling water slowly, that is, to discharge it from the heating element 20 at a high temperature. Such arrangement permits efllcient heating of cars connected to a locomotive and no longer makes it necessary to withdraw steam from the boiler for heating purposes. Live steam then will be used at the most for the initial heating 01 a train when it is standing still. T

Elastic fluid condenser arrangement including the combination 01 a condenser having a cooling element, a tank connected to the cooling element, a surface type heat exchanger and a pump connected in series with the tank and the cooling element, and means for forcing air into the surface type heat exchanger and automatically variably adjusting the flow of air in response to, temperature conditions of .the cooling medium at the outlet of said tank.
