the definitive ground freezing resource
Recent software developments have introduced models that couple the traditional heat transfer model with groundwater flow models to evaluate the required freezing time for ground freezing systems and to evaluate the required refrigeration loads. This paper discusses the application of these models and compares them to actual field results on key ground freezing projects.
