<p>Disclosed is an assembled block type artificial skating rink, comprising: a refrigeration system (1), multiple liquid supply main pipes (42), and multiple gas return main pipes (41) located on the same circuit as the liquid supply main pipes. The multiple liquid supply main pipes converge at a liquid supply main pipe (32), and the multiple gas return main pipes converge at a gas return main pipe (31). The liquid supply main pipe communicates with a refrigeration liquid output end of the refrigeration system via at least one liquid supply riser (22), and the gas return main pipe communicates with a gas recovery end of the refrigeration system via at least one gas return riser (21). The gas return main pipes are each respectively sheathed on the liquid supply main pipes to form multiple groups of sheathed main pipes. The artificial skating rink is split into different block-shaped areas, each area independently being provided with a freezing discharge pipe and a sheathed collection pipe connected with the sheathed main pipes. A refrigeration liquid control valve set is mounted on the liquid supply main pipes, and a gas control valve set is mounted on the gas return main pipes. According to the requirements of use, the skating rink can independently freeze the required area, thereby obtaining the required form for the surface of the ice, effectively saving on energy resources.</p> |
