The temperature of water constantly increases, thus hot water needed for obtaining；Refrigerant in subsequent 4th heat exchanger tube (27) is heated by oil smoke, is passed through
Second circulation pumps (25) driving, and the refrigerant in the second pipeline (34) enters evaporation in the first double-source heat pump (24) after constantly absorbing heat
Heat release, to obtain air-conditioning heating institute calorific requirement, the low-temperature flue gas after eventually passing through accumulation of heat and two-stage heat exchange is out of fume pipeline
Discharge is outdoor；
During step 3, the oil smoke for stopping culinary art being interrupted, hot water storage tank (8) interior low-temperature water heating enters first by regenerative apparatus (4)
Heat exchanger tube (20), heat pass to the first heat exchanger tube (20) interior flowing hot water from heat-storing material (4-2), and final low-temperature water heating is inhaled
It receives thermal temperature to increase, the heat-storing material (4-2) of regenerative apparatus (4), which is undergone phase transition, releases thermal temperature reduction, and hot water is first
It is returned in hot water storage tank (8) afterwards under the driving effect of circulating pump (14) by the first heat exchanger tube (20), perseveration, to obtain
Required hot water；At the same time, in double-source heat pump (24) low-temperature refrigerant by regenerative apparatus (4) enter the second heat exchanger tube (31),
Heat passes to refrigerant from the heat-storing material (4-2) of regenerative apparatus (4), and final refrigerant is heated, the storage of regenerative apparatus (4)
Hot material (4-2) stores heat and is taken away by refrigerant, and the refrigerant being heated passes through the under the driving of second circulation pump (25)
Back to evaporation heat release, perseveration, to obtain needed for air-conditioning heating in double-source heat pump (24) after two heat exchanger tubes (31) heat exchange
Heat.
