Abstract

The invention relates to a solar refrigerator, in particular to a solar photovoltaic refrigerator system based on a DC variable frequency compressor and phase change cold storage. The system mainly comprises two parts, i.e. a solar photovoltaic generation system and a refrigeration system of a refrigerator. The solar photovoltaic generation system comprises a photovoltaic panel, a controller and a storage battery; and the refrigeration system of the refrigerator mainly comprises the compressor, a condenser, a throttling device, a freezer / refrigerator evaporator and a cold storage device evaporator connected with the freezer / refrigerator evaporator in parallel. A heat tube is adopted as a device for transferring heat between a cold storage device and the space of the refrigerator. The cold storage device stores cold when electric power is sufficient, and releases cold when the electric power is insufficient. The storage battery supplies power when the cold of the cold storage device is fully released and the power that the photovoltaic panel generates is still insufficient. In addition, the storage battery and the controller of the photovoltaic generation system are integrated with the refrigerator, and the appearance structure is more attractive and practical. The system fully does not consume the electric power of a power grid, and has very profound research significance in saving electric power and effectively utilizing renewable energy.

Description

technical field [0001] The invention relates to a solar refrigerator, in particular to a solar photovoltaic refrigerator system based on a DC frequency conversion compressor and phase change cold storage, and belongs to the field of photovoltaic refrigeration. Background technique [0002] Solar energy is the most widely used clean renewable energy. Solar refrigeration technology has good seasonal matching, that is, the solar radiation is strong in summer, and the corresponding cooling demand is also the largest, while the solar radiation is relatively weak in winter, and the cooling demand is also small at this time. Based on this feature, solar refrigeration technology has received more and more attention and research. [0003] Compared with solar absorption and solar semiconductor refrigeration technologies, solar photovoltaic refrigeration technology has the advantages of better cooling effect, higher energy utilization rate, and lower self-loss. With the vigorous devel...
