A refrigerant plant or system includes a refrigerant circuit (10) which comprises in series a first primary heat exchanger (11) with which heat is dumped into the environment, and a second primary heat exchanger (20) with which the heat delivered is reused for locality heating, for instance. The refrigerant is driven in opposite directions through the primary heat exchangers (11, 20). Secondary heat exchangers (31-33) are coupled between and in parallel with the primary heat exchangers (11, 20). Condenser units (51-53) belonging to at least one refrigerating machine (41-43) are cooled by the secondary heat exchangers (51-53). The rates of flow of refrigerant through the primary heat exchangers (11, 20) is controlled so that those refrigerating machines which shall satisfy heat recovery through the medium of a high temperature of condensation are selectively chosen. <IMAGE> |
