Abstract

The heat exchange system is used for heating a first fluid with a second fluid, and includes a first fluid circuit comprising an upstream end, a downstream end and an intermediate portion therebetween and a second fluid circuit comprising an upstream end, a downstream end and an intermediate portion therebetween. The heat exchange system also includes a flooded heat exchanger unit wherein the intermediate portions of the first and second fluid circuits extend and are in adjacent, thermally-conductive contact for allowing heat transfer from the second fluid to the first fluid. The flooded heat exchanger is capable of being flooded in a determined proportion within the second fluid circuit intermediate portion. The heat exchange system further includes a second fluid circuit control valve located at the second fluid circuit downstream end, for controlling the flow rate of the second fluid through the second fluid circuit, whereby the proportion of the heat exchanger which is flooded within the second fluid circuit intermediate portion can be selectively calibrated. The heat exchange system also includes a first fluid pre-heating device located between the first fluid circuit upstream end and the heat exchanger unit, for partly pre-heating the first fluid before it is heated by the second fluid, whereby the first fluid temperature at the first fluid circuit downstream end will be stabilized.
