AI Technical Summary

Technical Problem

Traditional refrigeration systems cannot effectively utilize electricity price differences, resulting in low cooling efficiency during valley power periods and high operating costs during peak power periods.

Method used

A cooling refrigerator is designed, including a cooling system, a cooling module and a control system. By switching to the cooling mode during the valley period, the cooling capacity is stored using phase change materials; when switching to the cooling mode during the peak period, the cooling capacity is released to reduce the power consumption.

Benefits of technology

It has achieved efficient cooling storage during valley power period and effective cooling during peak power period, making full use of peak and valley power price difference, reducing the operating cost and energy consumption of refrigerators, and improving economic benefits.

Abstract

The invention belongs to the technical field of refrigeration, and relates to a cold storage refrigerator and a control strategy thereof. The cold storage refrigerator comprises a refrigerator body, a refrigerating system, a cold storage module and the like. The refrigerating system comprises a compressor, a condenser, a throttling device and an evaporator which are sequentially connected to form a refrigerating loop, a first electric control three-way valve is arranged at an outlet of the throttling device, and a second electric control three-way valve is arranged at an inlet of the compressor; the cold storage module comprises a phase change cold storage device and a cold storage pipe wound in the phase change cold storage device, the phase change cold storage device is attached to the wall of the inner container, and the two ends of the cold storage pipe are connected with the two electric control three-way valves correspondingly, so that the compressor, the condenser, the throttling device and the cold storage module are sequentially connected to form a cold storage loop; the control system is connected with the two electric control three-way valves so that the refrigerating loop or the cold storage loop can be conducted. Switching between the refrigerating loop and the cold storage loop can be achieved, efficient cold storage in the valley electricity period and effective cold release in the peak electricity period can be achieved, cross-period intelligent dispatching of the cooling capacity is achieved, and the peak-valley electricity price difference is fully utilized to reduce the operation cost of the refrigerator.
