Along with the rapid development of the urbanization process in China, the demand of people on cold and heat is increased, so that the cooling and heating load of a building is rapidly increased, and the unit is required to increase the cooling and heating load. On the other hand, when the system is in the energy consumption valley period, the system is difficult to quickly adjust along with the change of the external cold and hot load.

Therefore, the two systems which are separately arranged have the defects of high investment and maintenance cost and large occupied space. And the water distribution pipe of the existing cold and heat accumulation system is relatively disordered when being arranged, so that the water flow disturbance is large, the water flow uniform distribution effect is poor, the thickness of the thermocline is high, and the water outlet temperature cannot be ensured.
