The invention relates to energy, primarily for equipment-condensing exhaust steam after the steam turbine nuclear power plants or thermal power plants.

Known cooling device for cooling and condensing the exhaust steam, comprising a condenser, a dry cooling tower and a vortex tube [1].

The disadvantage chiller plant design is the complexity and high cost of energy at her work.

The technical result of the invention is to simplify the design and reduce energy consumption.

To achieve a technical result in the cooling installation comprising a cooling medium exhaust steam, according to the invention is excluded vortex tube and dry cooling tower and condenser as a means of serving to cool the exhaust steam used heat exchanger tubes made of heat resistant and heat insulating material, in which is mounted thermopile cold junctions are facing the inside of the pipe, and hot outside.

In addition, the heated hot junctions of the air used for space heating and warm time is thrown away.

The invention is illustrated by the drawing, which shows a capacitor in the section.

The capacitor includes a housing 1 with an orifice 9 for the admission of steam in the turbine exhaust, the receiver pair 3, the collector to the completion of 4 and heat exchanger tubes 6, made of heat resistant and heat insulating material, open at the top in the receiver pair 3 and below in the condensate collector 4. In the walls of heat exchange tubes mounted thermopile cold junctions 7 are located inside the tubes 6, and hot 8 - face outward in the tube space of the condenser. The condensate is thrown through the pipe 5. On the pipe 10, indicating annulus with the atmosphere has a valve 11. The annular duct 12 extending from the housing 1 and coming back to it, fitted with a valve 13 and the blower 14.

The device operates as follows.

Exhaust steam through the neck 9 is supplied into the cavity 3, whence it moves through the channels of the heat exchange tubes 6. Since there is considerable difference in temperature between the exhaust steam and cold junctions, there is a transition of heat from the exhaust steam to the cold junctions 7 thermopile by two physical mechanisms, the direct contact of steam with cold junctions 7 and due to the radiation heat transfer between them [2].

As you move within the channels of the heat exchange pipes exhaust steam is cooled and condensed. The condensate is removed through pipe 5.

Hot hot junctions 8 air from the annulus through the pipe 10 is thrown away, and in cold weather the circular duct is served on ebohr is in space. The annular duct 12 within the heated rooms feature electroheater devices.

Thus, the exception of the design of the vortex tube and dry cooling tower and the application of heat exchanging tubes with thermopile for cooling the exhaust steam in comparison with the prototype to simplify the design and reduce energy consumption.
