Abstract

The continuous mode of operation of artificial ground freezing (AGF) systems in long-term applications requires intensive energy consumption, which leads to immense operating and maintenance costs not to mention a large carbon footprint. Therefore, a reliable technique is needed to reduce energy consumption whilst maintaining sufficient structural stability and safe operation. This paper introduces and demonstrates a novel concept of the freezing-on-demand (FoD) by means of experiment and mathematical model. A fully controlled laboratory scale experiment is conceived and developed to assess the feasibility of the FoD concept. A three-dimensional mathematical model has been derived, validated, and utilized to simulate the AGF under three operating scenarios: (i) continuous mode, (ii) time-based FoD, and (iii) temperature-based FoD. Each scenario examines the effect of several designs and operating parameters on the ground’s response and energy consumption. The results suggest that the concept of the FoD could significantly reduce energy consumption by up to 46%, as compared to the conventional counterpart which shows its potential for practical applications.
