A refrigerating circuit for a facility, called thermorefrigerating pump, for the heating and/or cooling of fluids, comprising: - a compressor, - an exchanger (21, 22), called condenser exchanger, comprising a condenser circuit, - an exchanger, called balancing exchanger, comprising a circuit called condenser/evaporator circuit able to operate either as a condenser or as an evaporator, and preferably a fan associated with said balancing exchanger, - a first connecting node between a branch of the refrigerating circuit provided with the condenser exchanger (21, 22) and a branch of the refrigerating circuit provided with the balancing exchanger, said connecting node being located on the side of the outlet of the condenser exchanger (21, 22), - an exchanger, called evaporator exchanger, comprising an evaporator circuit, - a first fluid management device comprising four paths, including: - a first path, called inlet path, connected to the outlet of the compressor, - a second path, called low pressure path, - a third path connected to the balancing exchanger on the side opposite the first connecting node, and - a fourth path connected to the inlet of said condenser exchanger; - a second fluid management device comprising four paths, including: - a first path, called inlet path, connected to said first connecting node, - a second path, called low pressure path, - a third path connected to the inlet of the evaporator exchanger, and - a fourth path connected to the balancing exchanger, between the first connecting node and the condenser/evaporator circuit of the balancing exchanger; - a first expansion valve located between the third path of the second fluid management device and the evaporator exchanger, and - a second expansion valve located between the fourth path of the second fluid management device and the balancing exchanger, the second paths (512, 522) of the management devices being connected to a branch of the refrigerating circuit that extends between the outlet of the evaporator circuit of the evaporator exchanger and the inlet of the compressor; each fluid management device (51, 52) being configured to selectively assume a first configuration in which the inlet path (511, 521) is placed in communication with the third path (513, 523), the low pressure path (512, 522) being placed in communication with the fourth path (514, 524), and a second configuration in which the inlet path (511, 521) is placed in communication with the fourth path (514, 524), the low pressure path (512, 522) being placed in communication with the third path (513, 523). - a compressor, - an exchanger (21, 22), called condenser exchanger, comprising a condenser circuit, - an exchanger, called balancing exchanger, comprising a circuit called condenser/evaporator circuit able to operate either as a condenser or as an evaporator, and preferably a fan associated with said balancing exchanger, - a first connecting node between a branch of the refrigerating circuit provided with the condenser exchanger (21, 22) and a branch of the refrigerating circuit provided with the balancing exchanger, said connecting node being located on the side of the outlet of the condenser exchanger (21, 22), - an exchanger, called evaporator exchanger, comprising an evaporator circuit, - a first fluid management device comprising four paths, including: - a first path, called inlet path, connected to the outlet of the compressor, - a second path, called low pressure path, - a third path connected to the balancing exchanger on the side opposite the first connecting node, and - a fourth path connected to the inlet of said condenser exchanger;
