| 摘要 |
The invention concerns a plant for recuperating heat from preferably discontinuously arising waste water from, in particular, domestic households, commercial and industrial premises, etc. The plant comprises at least one counter current-flow heat exchanger through which the waste water flows and which is connected in circuit with at least one hot-water tank or boiler. The invention calls for a sensor (6), designed to detect the arrival of waste water, to be fitted in the line (10) carrying the waste water, the sensor being connected to at least one pump (1) or to a control unit (8) which controls the pump(s). When the sensor generates a signal indicating the arrival of waste water, the pump (1) is switched on and sucks the waste water in the line (10) out of the line and through the heat exchanger (3). |
