The parameters of ultra-low temperature refrigerator include the following aspects:
Temperature range: The temperature range of ultra-low temperature refrigerators is usually between -40℃ and -196℃. The temperature range of ultra-low temperature refrigerators of different models and brands will be slightly different.
Refrigeration method: Ultra-low temperature refrigerators generally use compressor refrigeration, and a few use absorption or thermoelectric refrigeration.
Refrigerant types: The types of refrigerants in ultra-low temperature refrigerators are also different. Common refrigerants include R134a, R404a, R508b, etc.
Internal volume: The internal volume of ultra-low temperature refrigerators of different models and brands will also vary, generally ranging from tens of liters to hundreds of liters.
Temperature control accuracy and stability: The temperature control accuracy and stability of ultra-low temperature refrigerators are also important indicators to measure their quality and performance. Generally, the temperature control accuracy is ±1°C or higher.
Power consumption: The power consumption of ultra-low temperature refrigerators is also a factor that needs to be considered, generally ranging from a few hundred watts to thousands of watts.
External dimensions: The external dimensions of the ultra-low temperature refrigerator are also factors that need to be considered. The sizes of ultra-low temperature refrigerators of different models and brands will be different. You need to choose the appropriate size according to the actual usage scenario.
Insulation materials and thickness: The insulation materials and thickness of ultra-low temperature refrigerators are also important factors that affect its performance. High-performance insulation materials are generally used, and the thickness is usually above 50mm.
Number of doors: The number of doors of the ultra-low temperature refrigerator is also a parameter that needs to be considered. There are single-door and double-door models.
Control method: The control methods of ultra-low temperature refrigerators include microcomputer control and mechanical control. Microcomputer control can achieve more precise temperature control.
Safety protection: The safety protection measures of ultra-low temperature refrigerators are also factors that need to be considered, generally including over-temperature protection, over-voltage protection, phase loss protection, etc.
Noise: The noise of ultra-low temperature refrigerators is also a factor that needs to be considered. Generally, the noise is below 50 decibels.
Shockproof design: The shockproof design of the ultra-low temperature refrigerator can reduce damage to the equipment caused by vibration during transportation and use.
Other functions: Some high-end models of ultra-low temperature refrigerators may also have other functions, such as automatic defrost, remote monitoring, etc.
