The invention discloses a heat storage coupling absorption type heat pump heat supply system. The heat storage coupling absorption type heat pump heat supply system comprises an electric heater, a heat storage device, an absorption type heat pump unit and a heat supply loop. The absorption type heat pump unit comprises a generator, a condenser, an evaporator, an absorber and a working medium pump.The output end of the generator is connected with the input end of the condenser. The output end of the condenser is connected with the input end of the evaporator. The output end of the evaporator is connected with the absorber. The absorber is connected with the generator through the working medium pump, and the generator is connected with the absorber through a pipeline. The heat supply loop is connected with the condenser. The heat storage device is connected with the generator through a heat transfer loop so that high-level heat energy can be provided, and the evaporator exchanges heat with air so that low-level heat energy can be provided. According to the heat storage coupling absorption type heat pump heat supply system, the COP value is high, the coal-to-electricity running costcan be greatly reduced, and the system structure is simple.
