Ice refrigeration mode

In the past, some stadiums usually used indirect refrigeration when making ice. That is, the way the refrigerant cools. Indirect refrigeration refers to the process of transferring the cold energy obtained by direct evaporative cooling to the ice surface through refrigerant to complete cooling. Ma Yitai introduced that its advantage is that the strength requirements for underground pipelines in skating rinks are very low. As long as it doesn't leak Plastic pipes can usually be used. The pressure-resistant parts are all in the refrigerator device.
