With the development of society and the improvement of living standard of people, the electricity consumption for production and living is continuously increased, and the electricity consumption is rapidly increased. The power supply is tension when the power consumption peak period often appears, and the power consumption is not fully utilized when the valley period, leads to the power grid power supply inefficiency, and the electric power resource waste is serious. Therefore, how to shift the power demand during the peak period, "shift peak and fill", balance the power supply, and increase the effective utilization of the power becomes a problem that needs to be improved at present. The national advocated a policy of 'peak-valley time-of-use electricity price', so that the ice storage air conditioning technology is valued and developed. The existing ice cold-storage air conditioner utilizes low-price electricity to make ice and store the ice in an ice storage device in the low-valley period of night electricity consumption, and the stored cold is released by ice melting in the peak period of daytime electricity consumption so as to achieve the aim of refrigeration. By adopting the cold accumulation air conditioning technology, the electric power resource can be fully utilized, the peak-valley period is balanced, the supply shortage is relieved, the capacity and the distribution capacity of the refrigeration equipment can be reduced, and the energy utilization rate is improved.
In order to increase flexibility of the mobile air conditioner and improve effective utilization of electric power, the existing ice storage mobile air conditioner stores cold through ice cubes, for example, an ice storage air conditioner disclosed in chinese patent publication No. CN112682880a, water after heat exchange of a surface cooler returns to a refrigerator to melt ice in the refrigerator, and the melted water provides a cold source for the surface cooler, but there are a plurality of problems, such as: (1) After the stored ice is used up, the melting water is required to be discharged from an ice water discharge port, and the ice can be reused after being added again, so that the replacement process is time-consuming, long-time continuous refrigeration can not be met, and the replacement process is inconvenient; (2) The ice-water mixture is pumped into the circulating pipeline, so that the pipeline is easy to be blocked; (3) The shell is internally provided with a condensed water storage tank which is connected with the outside of the ice cold storage air conditioner through a condensed water discharge port, so that the condensed water storage tank has a certain water storage volume and occupies a relatively small space, and condensed water is required to be discharged regularly, or the condensed water overflows.
