The artificial ground freezing (AGF) systems are typically designed to operate continuously for two main reasons: (i) to maintain a certain thickness of the frozen barrier which strengthens the ground’s structure, and (ii) to stop groundwater seepage and sustain a safe operating environment within the working area. This non-stop procedure, in contrast, leads to massive energy consumption. Therefore, it is crucial to introduce new techniques that reduce the energy consumption, while ensuring desired ground structure and safe operation. This paper discusses the concept of freezing on demand (FoD) in terms of experiment and model validation. We built a laboratory-scale AGF rig to quantify the ground’s behavior towards the FoD concept. We also developed a three-dimensional, conjugate-heat-transfer, mathematical model that simulates the transient AGF process with FoD technique. The model’s framework has been extended into in-situ geometry to examine the influence of the spacing between two pipes on the energy saving during the FoD process. The results show that the spacing has an inverse relationship with the drop in the energy consumption during the FoD. Undoubtedly, FoD concept gave a substantial drop in the energy consumption which could lead to the development of an energy-efficient AGF system.
