ABSTRACT:
The process of creating and maintaining an Integrated Mini Ice Surface is through the combination of a continuous pattern of copper pipe filled with freon covered with water connected to a series of thermostatic expansion valves which are connected to a 6 horse power condenser/compressor with a dehumidifier within the space which produces 3 mini ice surfaces. These ice surfaces allow an individual to practice or receive instruction in a confined shooting alley or lane which eliminates the risk of injury to another participant and the utility of quick ice hockey puck retrieval for continuous reuse.
