Heat exchanger (101 ) of the flooded type, comprising: - a primary tube bundle (10) inside which a first operating fluid, in particular water (or water + anti-freeze or other fluids), flows; - a skirt (1) surrounding the primary tube bundle (10) and receiving a second operating fluid which flows over the primary tube bundle (10); and - one or more extractable units (100), each in turn comprising: - a secondary tube bundle (19) which receives an auxiliary operating fluid, usually a liquid refrigerant supplied by a condensing plant; and - a secondary tube plate (7) for performing a removable connection to the heat exchanger, said plate allowing insertion of the secondary tube bundle (19) inside the skirt of the exchanger downstream of the primary tube bundle (10) relative to the flow of the second operating fluid (Fig. 1). |
