Abstract (en)
[origin: FR2894017A1] The pump has a primary circuit (20) including a compressor (10), an expander (14), and a condenser (12) comprising two heat exchange circuits. A heat pump comprises a pressure sensor (18), and a unit e.g. solenoid valve, switching the circulation of a refrigerating fluid between states in which it is circulated in one or two of the heat exchange circuits. A unit controls the switching unit according to the value of the signal from the pressure sensor. An independent claim is also included for a method of heating swimming pool water using a heat pump.
