Abstract: A packaged, pumped liquid, evaporative-condensing recirculating ammonia refrigeration system with charges of 10 lbs or less of refrigerant per ton of refrigeration capacity. The compressor and related components are situated inside the plenum of a standard evaporative condenser unit, and the evaporator is close coupled to the evaporative condenser. Single or dual phase cyclonic separators may also be housed in the plenum of the evaporative condenser.

Abstract: A monitored release solid feed system having a solid chemical feed tank, a storage tank located below the solid chemical feed tank, and an automated valve. The solid chemical feed tank is loaded with a blend of inhibitors and an indicator-chemical in a solid form. A detector measures the amount of indicator in the recirculating water and periodically compares it to a setpoint. If the value is below the setpoint, the automated valve opens allowing water to pass through the storage tank and the solid chemical feed tank thus carrying inhibitors and a proportional amount of indicator-chemical into the recirculating system.
