Definitions
- the present invention relates to cooling mediums for use in various applications including, without limitation, the cooling of ice-skating rinks and in building sprinkler systems, cold storage systems, plate freezers, blast freezers, brine freezers, cooling towers, air conditioners and condensers, radiator cooling applications, and heat exchangers.
- FIG. 1 An exemplary use of the invention is depicted generally in Figure 1 wherein there is depicted a primary refrigeration system 10 opera tively connected to a secondary refrigeration system 12, which may be used in numerous applications including the cooling of an ice skating rink 14.
- the primary refrigeration system 10 is a closed loop system that circulates refrigerant through the system 10 and includes the use of a compressor 16, a condenser 18, an expansion valve 20, an evaporator 22, and tube 24.
- the refrigerant flows through tube 24, as indicated by direction arrow 26, through the compressor 16, which raises the pressure of the refrigerant.
- the refrigerant then flows through the condenser 18, where the refrigerant condenses from vapor form to liquid form, giving off heat in the process.
- the secondary refrigeration system 12 includes a pump 28 and a length of tube 30 that is positioned underneath the surface of the ice-skating rink 14.
- the pump 28 circulates the cooling medium of the invention, as described below, through the length of tube 30 as indicated by direction arrow 32 to cool the ice-skating rink and maintain the proper ice temperature.
- FIG. 2 Another exemplary use of the invention is depicted generally in Figure 2 wherein there is depicted generally a sprinkler system 48 that may be installed in a building 50.
- the sprinkler system 48 operates when there is a fire situation and provides a fluid to the fire to extinguish the fire.
- the building 50 is generally depicted but may include all types of buildings that use or have installed a sprinkler system.
- the sprinkler system 48 includes generally a fluid line or tube 52 operatively connected to a fluid source 54.
- the fluid source 54 provides the fluid, as indicated by direction arrow 56 to a plurality of sprinklers 58 positioned, through the building.
- the fluid In the event of a fire, the fluid is dispersed through the sprinklers 58 and onto the fire, thereby extinguishing the fire. It is known to use a salt-water solution as a fire extinguishing fluid.
- the known saltwater solution has a lower freezing point to prevent the fluid from freezing within the supply tubes in cold environments.
- the invention contemplates the use of the cooling medium, as described below, as the fluid used within the sprinkler system 48.
- the ice-rink 14 may be replaced with an open tank 60. Materials may be placed directly in the tank 60 for freezing.
