Abstract (en)

[origin: EP0049503A2] 1. A hot-water heating plant with heat pump (18) the condenser (8) of which consists of a double-tube heat exchanger (9, 10) whose internal tube (9) is connected to a heat buffer (1) in the circuit via a recirculating pump (13), the buffer consisting of a vertical tank (2) filled with heating water and provided with connections for heating water supply (6) and reflux (7), characterized by the fact that the condenser (8) is arranged in the upper zone of the buffer tank (2) and its internal tube (9) discharges with a multiplicity of outlet openings into the upper zone of the tank (2), while the recirculating pump (13) sucks up from the lower zone of the tank (2), and that the delivery capacity of the recirculating pump (13) can be adjusted in dependence on the refrigerant pressure in the external tube (10) of the condenser (8) in such a way that the refrigerant pressure is kept at a constant level in operation.
