s4: if the user only needs to use the central air conditioner at the peak period of electricity utilization, the central air conditioner is firstly enabled to work from eleven to seven in the morning of the next day, the chilled water with the temperature of 5 ℃ generated after the air conditioner works flows to the cold storage box (2) through the pipeline under the action of the chilled water pump, at the moment, the heat exchange between the water in the pipeline and the phase change material is generated, the heat is released by the phase change material, the water in the pipeline absorbs the heat, finally, the water with the temperature of 5 ℃ flows back to the main machine of the central air conditioner after passing through the cold storage box (2), then when the electricity consumption is in the peak period in the daytime, the electricity cost is high, the host machine is closed at the moment, the cold storage box (2) is only used for cooling, the 8 ℃ chilled water flows from the interior of the cold storage box (2) to the end user through the pipeline under the action of a chilled water pump, finally obtained 13 ℃ water flows back into the cold storage box (2) to send heat exchange with the phase-change material again, the water in the pipeline releases heat, and the phase-change material absorbs heat, so that the effects of saving the electricity cost and refrigerating can be achieved when the electricity consumption is in the peak period;
s5: if the user needs to start the central air conditioner in twenty-four hours all day, the flow direction of the frozen water in the pipeline is as follows at the time of the electricity consumption valley period: the process is characterized in that the central air-conditioning host, the cold storage box (2), the refrigerating water pump, the end user and the central air-conditioning host circulate in such a way that 5 ℃ refrigerating water generated after the central air-conditioning works exchanges heat with the cold storage box (2) firstly, the refrigerating water absorbs heat, the phase-change material releases heat, namely, the cold accumulation process of the cold storage box (2) is completed, then 8 ℃ water flowing out of the cold storage box (2) flows to the end user to send heat exchange, the refrigerating water after the user realizes refrigeration becomes 13 ℃ and flows back to the central air-conditioning host, and when the electricity consumption is in a peak period, the flow direction of the refrigerating water in the pipeline is changed to: the central air-conditioning host machine, the frozen water pump, the tail end user, the cold storage box (2) and the central air-conditioning host machine, wherein at the moment, the frozen water at 13 ℃ discharged after the tail end user realizes refrigeration is subjected to heat exchange through the phase-change material cold storage device, the frozen water releases heat, the phase-change material absorbs heat, the cold discharge process of the phase-change material cold storage device is completed, and the obtained frozen water at 8 ℃ flows back to the central air-conditioning host machine, so that the effect of saving electricity charge can be achieved when the central air-conditioning is started in twenty-four hours all day;
s6: in the electricity consumption valley period, two pipelines of 5 ℃ refrigerated water generated after the central air-conditioning host works flow to each other, one pipeline firstly generates heat exchange through the cold storage box (2), the refrigerated water absorbs heat, the phase-change material releases heat to complete the cold storage process of the cold storage box (2), then the formed refrigerated water with the temperature of 8 ℃ is mixed with the refrigerated water with the temperature of 5 ℃ in the other pipeline to form 6.5 ℃ refrigerated water which flows to the end user under the action of the water pump, the end user realizes that the refrigerated water with the temperature of 13 ℃ generated after refrigeration flows back to the central air-conditioning host again, in the electricity consumption peak period, the end user realizes that the two pipelines of 13 ℃ refrigerated water generated after refrigeration flow to each other, one pipeline flows to the central air-conditioning host to generate the refrigerated water with the temperature of 5 ℃ through the work of the host, the other pipeline sends heat exchange to the phase cold storage box (2), the refrigerated water releases heat, the phase-change material absorbs heat, namely, the cold discharge process of the cold storage box (2) is completed, the chilled water of 8 ℃ is generated, then the water in the two pipelines is mixed to form the chilled water of 6.5 ℃, and the chilled water flows to the end user again under the action of a water pump.
