A liquid cooling system for an outdoor ice forming surface provides a geothermal heat pump that has a refrigeration circuit with a compressor that is disposed between a cold tube section and a hot tube section. An outdoor structure has an upward facing ice forming surface that is configured to retain a body of ice, where a coolant line is provided at or near the ice forming surface. A fluid pump is coupled with the coolant line and is configured to circulate liquid through the coolant line and over the cold tube section of the geothermal heat pump to dispense heat before being recirculated to the ice forming surface of the outdoor structure.

A snow mold includes a front snow mold portion and a back snow mold portion. The back mold portion is operable to be coupled to the front mold portion by inserting protrusions disposed on a flange of the back mold portion into receptacles disposed on a flange of the front mold portion. The front and back mold portions may be coupled by rotation of a rotatable fastener.

A method of discharging artificial snow (S) from a snow making facility (20) including an evaporator vessel (1) and producing snow by means of the technique of freezing water under vacuum pressure by maintaining a vacuum pressure in the evaporator vessel and producing water vapor that absorbs the latent heat of vaporization from the water, whereby the water temperature drops until it freezes and reaches the super cooling temperature that corresponds to the existing vacuum pressure, wherein produced snow is withdrawn from a bottom portion (1A) of the evaporator vessel by means of a first pipe screw conveyor (4), the withdrawn snow is conveyed from the first screw conveyor through a controlled first valve (6) and into a second pipe screw conveyor (5) and snow is discharged to the atmosphere from the second screw conveyor through a controlled second valve (7). A facility for producing artificial snow as well as a method for controlling the quality of produced artificial snow are also provided.

A climate facility comprises one or more recreation areas with an ice or snow cover; a climate control system which keeps the facility at a temperature above freezing in a range such that a portion of the snow or ice melts on a predetermined cycle; a drainage system to collect the melt; and a recycle system to use the melt in the formation of new snow.

A method for building an ice structure includes making a plurality of ice logs and attaching the ice logs together to form a support structure. The support structure may be two or more stories high and may be constructed by freezing the ice logs together.
