When the working fluid of the cold accumulation bed is pumped away by the pump, the preparation fluid enters the working part structure, and meanwhile, the fluid which completes heat exchange in the system is pumped to the preparation part structure to form a new preparation structure.
2. The working part and the preparation part of the cold storage bed are respectively provided with an inlet and an outlet, each inlet and outlet is connected with a reversing valve, and the flow path direction of the first reversing valve is controlled according to the working requirement. The first direction changing valve is switched to the heat exchanger side flow path when the cold storage bed is in the magnetizing period, and the first direction changing valve is switched to the cold exchanger side flow path when the cold storage bed is in the demagnetizing period. Each cold accumulation bed and the structures of the pump, the reversing valve and the like form a unit body which can independently complete the circulation of fluid.
3. The pump can be arranged at the outlet on the preparation side, when the pump is started, the fluid in the heat exchanger or the cold exchanger is selectively pumped to the structure of the preparation part of the cold accumulation bed according to the working requirement, and simultaneously the fluid in the original preparation part is pumped to the working part, so that a circulation is formed, and the cold accumulation bed continuously works.
Has the following beneficial effects:
1. the condition of mixed flow of cold and hot fluid is avoided, and the heat exchange effect is improved.
2. The cold and hot outlets of the cold accumulation bed are prevented from being circularly replaced, the single outlet of cold and hot is realized, and the cold and hot fluid is favorably shunted.
