Document Type and Number:
WIPO Patent Application WO/2011/129035
Kind Code:
A1
Abstract:
Provided is an ice rink refrigeration facility with which ice temperature can be readily managed and an ice rink can be uniformly refrigerated regardless of the installation distance between refrigeration pipes. An ice rink refrigeration facility (100) in which a refrigeration pipe group (1) that has a plurality of refrigeration pipes (11) is disposed at the base of an ice rink (10) and CO2 brine is passed through the refrigeration pipe group (1) to refrigerate the ice rink (10), wherein the ice rink refrigeration facility (100) comprises: a tabular heat conductor at the top surface of the refrigeration pipes (11); a CO2 circulation circuit (3) which is connected to the refrigeration pipe group (1) and circulates CO2 brine; an ammonia cooling cycle which circulates ammonia refrigerant; and a cascade capacitor (211) which exchanges heat between the CO2 brine and the ammonia refrigerant, and refrigerates and re-liquefies the CO2 brine using the ammonia refrigerant.
