摘要: Abstract LNG vaporizer is widely used all over the world to vaporize by using seawater. An intermediated fluid type (IFV) uses between and heat source transfer heat, enable utilize cold energy for a cryogenic power generation, so on. Conventionally propane has been as an fluid; however, refrigerants other than are recently needed because of diversified usage environments. In this study, R32 R410A selected their feasibility discussed in aspect. By number unit (NTU) method, prediction boiling condensation rate tube bundles was carried out. The demonstrated that those can increase vaporization with IFV from base line propane. From those, refrigerant use shown.
