Working range: the outlet temperature of cooling water is 22°C to 37°C; The temperature difference of the cooling water inlet is 3.5 °C to 10 °C; the outlet temperature of the refrigerant liquid is -55 °C to -110 °C; the temperature difference of the inlet and outlet of the refrigerant liquid is 2.5 °C to 5 °C.
3. When leaving the factory, there is a pair of stainless steel wire tooth connections at the entrance and exit of refrigerant liquid, and the refrigerant (alcohol) is prepared by the user.
4. The above specifications are subject to change without notice, which helps our company to bring the latest scientific and technological achievements to customers at any time.
The company has independent intellectual property rights of diversified mixed working fluid environmental protection refrigerant, international advanced natural cascade refrigeration technology set research and development, design, production, sales of single compressor ultra-low temperature cascade freezer (-80 °C ~ 160 °C) to achieve a number of technological breakthroughs, gradually replace the traditional multi-compressor cascade freezer system and liquid nitrogen refrigeration method, has been maturely used in various industries.
The self-cascading refrigeration mechanism cooling technology of one-time compression and multiple natural coagulation mixing working fluid adopts a single compressor and uses multiple mixed working fluid as refrigerant to achieve a low temperature refrigeration of -160 °C, which exceeds the refrigeration effect of two or three compressors using traditional cascade freezers. It greatly simplifies the structure of the refrigeration system, reduces the initial investment cost, reduces the energy consumption of the system operation, and improves the reliability of the system. The self-cascading refrigeration unit refrigeration system adopts the distillation method to cleverly complete the efficient separation of lubricating oil and mixed working fluid to ensure that the system does not have oil plugging problems in the low temperature section. Simple structure, stable operation, high energy efficiency, easy miniaturization, with a number of innovative technologies.
Self-cascading freezers compared to traditional three-stage cascade freezers. In comparison with the same low-temperature refrigeration of -100 °C, this technology reduces two compressors and two plate heat exchangers compared with the three-stage cascade cycle, and only adds a self-made liquid divider and recuperator, and replaces the multi-stage refrigerant of the existing cascade refrigeration unit with mixed working fluid, which greatly reduces the cost, energy saving and energy consumption, and the system structure is simple and the operation is stable.
