O chiller de baixa temperatura é um tipo de equipamento de refrigeração que pode fornecer uma fonte fria abaixo de 0 ℃. Geralmente se refere à temperatura de uso de 5 a 35 ℃. O refrigerante pode ser transportado por solução aquosa de etilenoglicol ou cloreto de cálcio, e o evaporador com maior concentração precisa de tratamento anticorrosivo. A taxa de compressão do chiller de baixa temperatura para o compressor é maior, então a maioria dos campos criogênicos adota um sistema mais complexo do que um único compressor. A compressão em cascata ou em dois estágios... Low temp chiller runs smoothly and reliably, is not easy to damage, and has low noise. Because the compressor lubricating oil is supplied by a high and low pressure difference, the built-in oil of the compressor has high oil separation efficiency. In today’s society, the application of refrigeration equipment is more and more extensive. Modern refrigeration devices are all cooled by chillers. The market prospect of chillers is promising. The advanced countries in chiller development technology are still some developed countries in the West. Combined their development trend with the actual situation of their country, they vigorously improve the shape of the chiller, constantly improve the performance of the chiller to achieve the effect of smaller size and greater efficiency of the chiller. Nowadays, with the increasingly fierce market competition and the maturity of water chiller development technology, miniaturization and high- efficiency water chillers have become a new trend. At the same time, in order to adapt to the rapid development of industrial production, more personalized and more practical products will continue to emerge.
