Advantages of cascade cryogenic refrigeration system industrial chillers
The cascade refrigeration system is a low-temperature refrigeration system that uses more than two refrigerants and combines them with a heat exchanger (condensation evaporator) in more than two systems. For the chiller of binary cascade refrigeration system, it consists of two separate refrigeration systems, one is a high temperature system and the other is a low temperature system. The low temperature system is used to cool the environmental laboratory, and the high temperature system is used to cool the exhaust gas of the low temperature system to condense it at a lower temperature. This also achieves the goal of reducing the compression ratio and increasing the gas transmission coefficient.
The advantage of this cascade low-temperature refrigeration system industrial chiller is the use of medium-pressure refrigerant suitable for high-temperature systems and high-pressure refrigerant suitable for low-temperature systems. Because the specific volume of high-pressure refrigerant gas at low temperature is much smaller than that of medium-pressure refrigerant, therefore, at low temperature, the refrigeration capacity of the same type of compressor for cascade refrigeration is several times larger than that of two-stage compression refrigeration Stacked chiller chillers can save a lot of investment and construction area. And the high-pressure refrigerant works at a suction pressure greater than or close to an atmospheric pressure at low temperatures, and will not infiltrate the system as often as a two-stage cryogenic system.
An engineer once used R13 as the low-temperature grade and R22 as the high-temperature binary cascade refrigeration system for comparison. With the same cooling equipment investment, the dual-stage compression refrigeration system chiller is more than three times the cascade refrigeration system chiller The installed power of the motor, the two-stage compression refrigeration system is more than double that of the cascade refrigeration system. Due to the large number of compressors in the two-stage refrigeration system and the increase in friction power, the energy consumption of the two-stage compressor is more than 1.5 times that of the cascade refrigeration system.
In addition to the user's request for temperature changes, the ambient temperature is higher than -55 ℃ above can use cascade refrigeration system industrial chiller. At present, there are more and more cold sources using cascade refrigeration system as low-temperature experimental equipment.
