Low-temperature Air-cooler Economic Analysis

Focusing on the characteristics of cold winter in the Northeast, this paper carries out heat transfer performance experiments and economic analysis of low-temperature air-cooler. The study results show that: The heat transfer performance of low-temperature air-cooler is good and able to meet the demands of refrigeration in winter; the operating cost is less than the original ammonia or Freon cooling system, and the economy is good. The low-temperature air-cooling system can be used on the basis of the present refrigeration system in order to enhance the economic quality.
