Abstract

See full text

A modular assembled artificial skating rink includes a refrigerating system, a plurality of liquid-supply main pipes and air-return main pipes in the same pipe line as the liquid-supply main pipes. The liquid-supply main pipes communicate with a liquid-supply header pipe. The air-return main pipes communicate with an air-return header pipe. The liquid-supply header pipe communicates with a refrigerant-fluid outlet of the refrigerating system through at least a liquid-supply standpipe. The air-return header pipe communicates with an air-recovery end of the refrigerating system through at least an air-return standpipe. Each liquid-supply main pipe is sheathed in a corresponding air-return main pipe, forming a plurality of groups of sleeve main pipes. The artificial skating rink is divided into different modular regions. Each of the regions has sleeve manifolds and ice-making pipes. Each liquid-supply main pipe has a refrigerant-fluid control valve bank, and each air-return main pipe has an air control valve bank.
