Be fixed on the lower end of tank body, hot water inlet/outlet pipe and cold water inlet/outlet pipe are inserted on tank body respectively, the medial extremity of hot water inlet/outlet pipe with
Hot water water distributing tray is connected, and the medial extremity of cold water inlet/outlet pipe is connected with cold water water distributing tray, is divided on hot water water distributing tray and cold water water distributing tray
Be not laid with multiple nozzles, attemperating unit is arranged on the madial wall of tank body, attemperating unit by power line respectively with hot water
Suction pump and cold water suction pump are connected, and attemperating unit includes multiple temperature sensors, multiple temperature sensors along tank body height
Direction is uniformly arranged successively from the bottom to top.
The beneficial effects of the utility model are：
The utility model sets attemperating unit in heat-accumulator tank, and the thickness to transition zone in heat-accumulator tank carries out monitor in real time,
When the thickness of transition zone is excessive, attemperating unit control hot water suction pump and cold water suction pump are operated, in making heat-accumulator tank
Water circulation is got up, and effectively prevents from being caused because transition zone is blocked up the generation of the energy waste phenomenon in heat-accumulator tank, improves accumulation of heat
The accumulation of heat effect of tank.
