1. A system for comprehensive utilization of renewable energy and waste heat, comprising:
a data center;
a water cistern, wherein: the water cistern adopts heating capacity of the data center to complete a heat storage process within a set first period, and adopts the heating capacity stored in the heat storage process to supply a heat release process within a set second period;
a water circulating system, provided with a plurality of water circulating loops; and
a refrigeration circulating system, provided with a plurality of refrigerant circulating systems; wherein,
the heat storage process and the heat release process are implemented by cooperation of the plurality of water circulating loops and/or the plurality of refrigerant circulating systems;
the water circulating system comprises:
a first water circulating loop, comprising: a first plate heat exchanger, the water cistern, a cooling tower, and a first heat pump evaporator, wherein one end of the first plate heat exchanger is in communication with the water cistern, the cooling tower and the first heat pump evaporator;
a second water circulating loop, comprising: a refrigeration unit condensing end, the water cistern, and the cooling tower, one end of the refrigeration unit condensing end is in communication with the water cistern and the cooling tower;
a third water circulating loop, comprising: a refrigeration unit heat recovery end and the water cistern, the refrigeration unit heat recovery end being in communication with the water cistern;
a fourth water circulating loop, comprising: the data center, the first plate heat exchanger and a refrigeration unit evaporator, a cooling water supply/return water interface of the data center is in communication with the first plate heat exchanger and the refrigeration unit evaporator;
