Discuss on Design Calculation of Spiral Tube Evaporator in Ice- water Temperature Uniformity Equipment

The evaporators in the ice-water temperature uniformity equipment take the shape of vertical spiral tube which lie in the ice water pool. Refrigeration system will feed super ammoniacal liquor inside of the spiral tube. The pumps whose function is blowing air into the ice water pool are used in this system, which create force convection. In this paper, the areas of evaporators are calculated through heat-transfer process. Based on engineering experience, it proves that the configuration is rational.
