Abstract:
1. A production line system comprising: one heat pump; at least one processing machine for processing work, fluidly connected to the heat pump; a washing machine fluidly connected to the heat pump; and a control unit electrically coupled to the heat pump, wherein the control unit is configured to control the heat pump to perform a plurality of processing steps including: a cooling processing step of cooling a coolant for the at least one processing machine, and a heating processing step of heating a washing fluid of the washing machine before or after processing by the at least one processing machine, wherein the heating processing step and the cooling processing step are performed in a heat pump cycle by the heat pump, the heat pump further comprising only an evaporator and a condenser, wherein the at least one processing machine and the washing machine are each fluidly connected by a refrigerant to the heat pump, whereby the coolant is cooled by heat exchange with the refrigerant in the evaporator during the cooling processing step and the washing fluid is heated by heat exchange with the refrigerant in the condenser during the heat processing step in one heat pump cycle.
