New ice rinks generally use ammonia as a refrigerant, but R-22 was the choice for many years, and the ice making systems in older rinks can contain several thousand pounds of R-22. In the approaching cold, hard reality of a post-R-22 world, how will rinks keep their ice cold and hard?
Filter driers are designed to remove foreign materials, such as moisture, dirt, sandpaper grit, soldering flux, small solder beads, and acid from a refrigeration or air conditioning system. However, filter driers are notorious for becoming restricted from moisture, sludge, dirt, or oil that has entered the system from a poor service practice or extreme operating conditions.
The first point to understand about refrigeration theory is that heat is energy, and it can be made to move. If enough heat is removed from a glass of water, the water will freeze to ice. When that heat is allowed to move back into the ice, the ice will melt.
Make way for the new class of refrigerants that await its entry in the global commercial markets. These are not the generic class of compounds that have been haunting the dreams and discussions of active environmental activists and forums respectively. When the world is out on the hunt for fresh additions to the list of already known refrigerants in the market, their approach is fixated to a singular point of product development — aim at coolants with low-global warming potential (GWP).
