Abstract

The present application relates to an ice rink carbon dioxide transcritical direct cooling system of ice rink refrigeration technology. A carbon dioxide refrigerating mechanism for reducing the temperature of the refrigerating layer and freezing the water on the refrigerating layer into an ice layer is arranged on the upper part, and a heat dissipation mechanism for heating the heating and anti-freezing layer is arranged on the heating anti-freezing layer to avoid the frost heave rupture of the heating anti-freezing layer; the carbon dioxide refrigerating mechanism includes: In the heat-absorbing refrigeration assembly arranged in the refrigeration layer, a carbon dioxide transcritical direct-cooling compressor unit for supplying liquid carbon dioxide and recovering gaseous carbon dioxide for the heat-absorbing refrigeration assembly is disposed on one side of the heat-absorbing refrigeration assembly. The present application has the effects of improving refrigeration efficiency and reducing waste of resources.

Description

technical field [0001] The present application relates to the technical field of ice rink refrigeration, in particular to a carbon dioxide transcritical direct cooling system for ice skating rinks. Background technique [0002] With the popularity of ice sports, skating is no longer limited by seasons, and indoor ice rinks have emerged as the times require. At present, artificial ice-making technology has become more and more mature. [0003] The current artificial ice-making device is generally equipped with a refrigeration pipe network under the pressure-bearing layer of the ice layer, and a refrigeration liquid supply main pipe and a return air main pipe are arranged on one side of the ice rink, which are connected by a refrigeration exhaust pipe, and the refrigeration medium in the refrigeration exhaust pipe is connected. It exchanges heat with the pressure-bearing layer to reduce the temperature of the pressure-bearing layer in direct contact with the ice layer, thereby...
