Hot water delivery system with heat pump conducts boiling process in water container by operating heat pump unit and circulation pump, stops pump before all water in container boiled up

摘要

The system has a heat pump unit with a heat exchanger, a water container in which heated water is stored for a supply, a circulation pump and a control unit for the heat pump unit and pump. The control unit conducts a boiling process in the water container by operating both the heat pump unit and circulation pump and stops the pump before all the water has been boiled up in the boiling process. The system has a heat pump unit (10) with a heat exchanger (13) in which a coolant on the high pressure side is in thermal exchange contact with water, a water container (16) in which the heated water is stored for a supply, a circulation pump (21) and a control unit for the heat pump unit and pump. The control unit conducts a boiling process in the water container by operating both the heat pump unit and circulation pump and stops the pump before all the water has been boiled up in the boiling process.
