20130036758 | REFRIGERATION EQUIPMENT WITH SLEEVE-TYPE COLLECTION PIPE FOR ARTIFICIAL SKATING RINK - Refrigeration equipment with a sleeve-type collection pipe for an artificial skating rink comprising at least a refrigerating system ( | 02-14-2013 |
20130055745 | ICE RINK COOLING FACILITY - An ice rink cooling facility | 03-07-2013 |
20130074538 | Led Display System for Ice Rinks - A display system for ice rinks comprises a panel having at least one enclosure containing a plurality of LEDs for displaying any indicia or images etc. The panel is adapted to be placed under the ice when in use. The panel is provided with a cooling apparatus for circulating a coolant through the at least one enclosure to remove heat generated by the LEDs. In one aspect, the panel includes at least one channel, within which a plurality of light emitting diodes, LEDs, are provided. The LEDs are controlled to display any indicia or images from under the ice when the panel is in use. The panel includes a manifold system for distributing a coolant through the channels so as to dissipate any heat generated by the LED, thereby, avoiding affecting the temperature of the ice. | 03-28-2013 |
20130233009 | CO2 REFRIGERATION SYSTEM FOR ICE-PLAYING SURFACE | 09-12-2013 |
20140196492 | System and method for a portable ice skating rink - A portable ice skating rink comprising, a flexible rubber sheet having a first end and a second end wherein the first end is connected to the second end thereby forming a sidewall, wherein the sidewall is positioned on a horizontal surface to form the border of a closed geometric shape thereby defining a skating surface area, and a flexible, water-proof slip draped over and connected to the sidewalls, thereby forming a liner of a structure capable of containing a liquid inward of the sidewalls to create a skating surface. | 07-17-2014 |
20140283539 | APPARATUS FOR MAKING AND PRESERVIING AN OUTDOOR FROZEN SURFACE - An apparatus for creating and preserving an improved, high performance outdoor frozen surface by covering a defined outdoor ground surface area with a layer of white base paper after clearing debris, litter, and other objects from the defined outdoor ground surface area. The layer of white base paper is saturated with water at near freezing or under freezing conditions to allow the water to freeze and hold the white base paper to the defined outdoor ground surface area. Thereafter, additional water is dispensed to build up a predefined thickness ice layer on the defined outdoor ground surface area. | 09-25-2014 |
20150322631 | MODULAR ASSEMBLED ARTIFICIAL SKATING RINK - 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. | 11-12-2015 |
