Heat pump and method for controlling the sources of input temperature at the heat pump

摘要

Heat pump, consisting of a refrigerant circuit (1), a heat distributor circuit barrel (3) and a heat sources circle barrel (2) with more than a heat source, comprising at least two parallel heating circuits (12, 18, 39), wherein the refrigerant circuit (1) at least two evaporating heat exchanger (4, 38) has, characterized in that each evaporating heat exchanger (4, 38) in each case a separate expansion valve (45, 49) and a controllable shut-off valve (46, 50) are associated with and that for the regulation of the refrigerant temperature in front of the compressor unit (8) of at least one of the expansion valves (45, 49) is constructed adjustable in its delivery, wherein at least one of the heat sources circle barrels (12, 18, 39) or more heat sources circle barrels are selected and activated.
