Abstract (en)
The object of the present invention is a heat pump system (1) comprising at least one refrigeration circuit (2) in which a refrigerant fluid circulates and operates at the primary side (24) of a main heat exchanger (21), one conditioning circuit (3) in which a technical fluid, used for room heating/cooling functions and/or for the production of domestic water, circulates and operates at the secondary side (25) of said same main heat exchanger (21). Said conditioning circuit (3) comprises at least one circulation pump (30) for said technical fluid, one or more terminals (31) for room heating/cooling and/or for the production of domestic water, and one safety valve (5) capable of being crossed by said technical fluid and of closing in case of refrigerant fluid leakage flows in said conditioning circuit (3) in opposite direction (FR) to that of operation (F) of the said technical fluid.
