Abstract:
1. A single flow circuit, comprising: an energy discharge device including a heat exchanger for exchange of energy with a fluid in the single flow circuit; and reversible pumping means consisting of a pumping device in series with the energy discharge device for pumping said fluid in a first flow direction through the heat exchanger, and for periodically pumping said fluid in a reverse flow direction opposite the first flow direction to thereby change a temperature difference distribution status of the energy discharge device to enhance heat exchange efficiency and reduce accumulation of impurities or pollutants in the flow circuit as it passes through the heat exchanger of the energy discharge device, and further comprising at least one temperature detecting device arranged to detect a temperature variation of the fluid and to transmit detected temperature signals back to the periodic direction-change control device such that when a temperature of the energy discharging device reaches a preset temperature, the fluid pumping direction is operatively controlled to pump the fluid in reverse flow direction and change the temperature difference distribution status of the energy discharging device.
