ABSTRACT:
A hot fluid stream is cooled by contacting it, in indirect heat exchange, with a base cooling fluid so long as the base cooling fluid accepts heat rejected from the hot fluid stream and adequately cools the same. When the cooling capacity of the base cooling fluid is inadequate supplemental cooling is provided contemporaneously and indirectly by contacting the hot fluid stream with a secondary cooling liquid which is cold thereby heating the secondary cooling liquid. The heated secondary cooling liquid is delivered to a hot reservoir for storage. The hot secondary cooling liquid is later removed from the hot reservoir, cooled and delivered to a cold reservoir for storage. The cold secondary cooling liquid is removed when needed from the cold reservoir and again delivered into indirect heat exchange with the hot fluid stream when the base cooling fluid provides inadequate cooling for the hot fluid stream.
The base cooling fluid can be a refrigerant such as ammonia and the secondary cooling liquid can be water. The hot fluid stream can be steam condensed in a condenser of an electric power generating plant.
