Energy storage defrosting device for heat recovery of gas-fired boiler

The invention provides an energy storage defrosting device for heat recovery of a gas-fired boiler. The energy storage defrosting device comprises the gas-fired boiler, a two-stage energy storage device, an outdoor defrosting coil pipe, an electric control valve, an anti-freezing water pump, an anti-freezing water pipe, a reverse circulation defrosting pipe, a heat consumer, an indoor heat exchanger, a compressor, a gas-liquid separator, an outdoor heat exchanger, an M1 electric three-way valve and an M2 electric three-way valve. According to the energy storage defrosting device, in the defrosting process, the air source heat pump unit does not need to reversely absorb heat in a heat user room to conduct defrosting, the heat source of the two-stage energy storage device is used for conducting defrosting, it is guaranteed that the indoor temperature does not fluctuate, meanwhile, the loss of the valve can be reduced, and the service life of the compressor is prolonged. 本发明提供一种燃气锅炉热回收的蓄能除霜装置，包括燃气锅炉、双级蓄能装置、室外除霜盘
