A movable cooling machine (1) and methods for cooling/freezing of all forms of liquid and solid matter, for example, wet snow in the ski trails, surface water, embankments, mines or roads and adapted for cooling medium such as dry ice and liquid nitrogen, in which the friction member (23), in particular wheels, skids or pontoons, resting on the surface, and forms a tight unit against the treatment area with the insulating members (3) and against the treatment area sliding insulating blade (5). Inside the cooling machine (1) is temperature sensor (37) whose quantities are processed in a controller which regulates the supply of coolant through the gas tap (13) and the speakers/vibrator (61) which reduces the Leiden-frost effect. By sealing the cooling unit against the treatment area and continuous determination of the temperature and air pressure, so are the supply of coolant optimized and cost and labor requirements are minimized and the quality of the work can be continuously monitored. |
