A heat pump device and method of controlling the heat pump device which includes a cold generating fluid circuit, a first heat exchanger associated with the circuit in order to draw calories from a heat containing fluid passing through a cooling circuit, and a second heat exchanger associated with the circuit in order to transmit calories to a fluid passing through a utilization circuit. The method comprises the steps of controlling the flow of heat-carrying fluid through the first heat exchanger in dependence upon the temperature of the fluid of the utilization circuit at the output of the second heat exchanger, and controlling the flow of fluid from the utilization circuit through the second heat exchanger in dependence upon the temperature or pressure of the cold generating fluid at the outlet of the second heat exchanger. The heat pump device includes a temperature sensor arranged in the utilization circuit at the outlet of the second heat exchanger, a first motorized valve arranged to control the flow of heat-containing fluid from the cooling circuit through the first heat exchanger in accordance with the output of a temperature sensor arranged in the utilization circuit at the outlet of the second heat-exchanger, a temperature or pressure sensor arranged in the cold generating fluid circuit at the outlet of the second heat exchanger, and a second motorized valve arranged to control the flow of fluid from the utilization circuit through the second heat exchanger in accordance with the output of the temperature or pressure sensor.
