<p>Refrigeration equipment with sleeve-type collection pipe for an artificial skating rink is provided, which at least comprises a refrigeration system (3), a refrigeration liquid supplying collection-pipe (1) and a return-gas collection-pipe (2). The return-gas collection-pipe (2) sheathes the refrigeration liquid supplying collection-pipe (1) along the length direction. The refrigeration system (3) is provided with a liquid supplying main pipe (41) and a return-gas main pipe (42) sheathed thereon. Both ends of the liquid supplying main pipe (41) are respectively communicated with the refrigeration liquid supplying collection-pipe (1) and the output end of the refrigeration system (3), and both ends of the return-gas main pipe (42) are respectively communicated with the return-gas collection-pipe (2) and the input end of the refrigeration system (3). Multiple groups of circulation pipes (6, 7) arranged in rows are juxtaposed at both sides of the return-gas collection-pipe (2) along the lateral direction. A first elbow connector (23) is arranged between the liquid supplying end of the circulation pipe (6, 7) and the return-gas collection-pipe (2), and a second elbow connector (22) is arranged between the return-gas end of the circulation pipe (6, 7) and the return-gas collection pipe (2). A liquid refrigerant jet pipe (11) is set between the first elbow connector (23) and the refrigeration liquid supplying collection-pipe (1) for communicating the two, and a return-gas hole (21) is provided on the return-gas collection-pipe (2) where it connects the second elbow connector (22). The refrigeration equipment has the advantages of easy processing, quick refrigeration and uniform ice-making.</p> |
