The invention relates to a distributed type energy supplying device and a cooling, heating and power decoupling method and device. When a center controller of the distributed type energy supplying device is in a large running mode and the electric load currently needed by a user side is larger than or equal to real-time power generating power, a power storing device is started to supplement electric energy for a user side, and an organic Rankin power generating unit is started to recycle waste heat of an absorbing type heat pump unit and a gas internal combustion engine and supplement the electric energy for the user side; under the large running mode and when the cold load currently needed by the user side is larger than or equal to first preset cold load, an electric heat pump unit is started to acquire the electric energy of the power storing device, the gas internal combustion engine and a renewable energy power generating device for refrigerating and supplementing cold gas for theuser side; and under the large running mode and when the heat load currently needed by the user side is larger than or equal to the first preset heat load, the electric heat pump unit is started to acquire the electric energy of the power storing device, the gas internal combustion engine and the renewable energy power generating device for heating and supplementing heat for the user side. Due tothe distributed type energy supplying device and the cooling, heating and power decoupling method and device, the energy utilizing rate can be increased, and environment friendliness is achieved.
