Embodiment Construction
[0013] The present invention is specifically described below in conjunction with accompanying drawing:
[0014] combine figure 1 What is claimed is a low-temperature preservation box with frequency conversion energy-saving technology, comprising a box body, and a thermal insulation foam layer is arranged inside the box body.
[0015] The box is provided with a control unit 1, a frequency conversion unit 2 and a cascade refrigeration unit 3. The cascade refrigeration unit 3 includes a fixed-frequency compressor and a condensing fan. The fixed-frequency compressor includes a high-temperature compressor and a low-temperature compressor. A single fixed-speed compressor can also be used within the unit. The frequency conversion component is respectively connected with the cascade refrigeration unit and the control unit, and the control unit is connected with the cascade refrigeration unit. The frequency components include a variable frequency regulator, which is installed at the ...

The invention provides a low-temperature freezer with a frequency conversion and energy saving technology and belongs to the technical field of refrigeration equipment. The low-temperature freezer comprises a freezer body. An overlaid refrigerating unit and a control component are arranged in the freezer body. The overlaid refrigerating unit comprises fixed-frequency compressors and a condensate fan. A frequency conversion component is also arranged in the freezer body and connected with the overlaid refrigerating unit and the control component, and the control component is connected with the overlaid refrigerating unit. The frequency conversion component comprises a frequency conversion regulator which is connected with the fixed-frequency compressors and the condensate fan. The control component controls the frequency conversion regulator to change the working frequency of the high-temperature-level compressor, the working frequency of the low-temperature-level compressor and the working frequency of the condensate fan, and the problems that an existing low-temperature freezer is low in refrigeration efficiency and energy utilization rate are solved.
Description
technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a low-temperature preservation box with frequency conversion and energy-saving technology. Background technique [0002] At present, the low-temperature storage box in my country only works at 220V and 50Hz, which also meets the requirements of my country's power grid, and due to the high cost of frequency conversion compressors or the limitations of technical use, there is no frequency conversion compressor that can be used in the field of low temperature storage boxes. Therefore, we are forced to change our thinking, innovate on the existing basis, and change the frequency to enhance the cooling performance and improve the work efficiency to achieve the purpose of saving energy and electricity. Contents of the invention [0003] Aiming at the problem that the existing low-temperature storage box does not have frequency conversion technology, the present inventi...
