<p>A power consumption economizer (10) for refrigerating machines of the chiller type, comprising, on a same line (11), pumping means (12) for a heat transfer fluid, an evaporator (13) of an associated refrigeration system (13a) for refrigerating the heat transfer fluid, sensors for detecting the flow and temperature of the heat transfer fluid and flow-rate adjustment means being associated with the pumping means. The system comprises bypass means adapted to exclude reversibly the evaporator (13) from the line.</p> |
