NATURAL REFRIGERANT: DISTRIBUTED HIGH EFFICIENCY REFRIGERATION WITH PACKAGED ULTRA LOW CHARGE AMMONIA (PULCA), ELECTRONIC REFRIGERANT INJECTION CONTROL (ERIC)
The technology that is the focus of this assessment can be described as a packaged refrigeration system the uses natural refrigerant, ammonia. It can be configured as either a rooftop or ground mount unit ranging in size from 25TR to 150TR. It is also in the category of an “ultra-low charge” system because the ammonia charge is measured in “ounces per ton” of refrigeration supplied (TR). It has the market brand name of NXTCOLD. The packaged system also includes a patented refrigeration control system1 that measures and governs the refrigerant quality and consistency within the evaporator coil.
