Refrigeration System Operation

AFE325

The AFE325 uses a forced draft air cooled condenser, capillary tube and hermetic compressor. The system uses R-134a as a refrigerant. High pressure, high temperature refrigerant is forced thru the condenser where it looses enough heat to condense. The high pressure liquid refrigerant then passes thru the capillary tube which causes a pressure drop in the evaporator. As the high pressure liquid refrigerant moves into the evaporator’s area of low pressure, the warm water and low pressure cause the refrigerant to evaporate and absorb heat from the metal walls of the evaporator. After the refrigerant has flowed thru the evaporator it goes back to the compressor thru the suction line as a low pressure vapor. At the compressor the cycle is repeated. The AFE325 uses a low side pressure control as a safety, it will shut the system down if the suction pressure is too low for reliable operation.

System Characteristics:

Note: This ice machine has a sealed refrigeration system. Tap into the system ONLY when it’s absolutely necessary. After tapping in, recovery, repair, evacuation and recharging, the piercing valve must be removed and the system re-sealed.

Typical Low Side Pressure*: 7 - 10 PSIG

Typical Discharge Side Pressure*: 130 - 165 PSIG

Typical Auger Drive Motor Amps (60 Hz): 2.8 - 3.1

Auger Drive Output RPM (60 Hz): 9.6

System Refrigerant Charge: 11 Ounces of R-134a

*Pressures depend upon air and water temperatures. Numbers listed are for 70oF. air/50oF. water and 90oF. air/70oF. water.
