  • Page 16: Refrigeration Systems

    2075DWRR Design Features Performance REFRIGERATION SYSTEMS Normal Vapor/Compression Cycle Refrigeration • Refrigerant is pumped from the compressor to the condenser as a high pressure, high temperature vapor. • As the refrigerant cools in the high pressure condenser, the vapor condenses to liquid. During this phase change, a great amount of heat is rejected with the help of the condenser fan.
  • Page 17 SERVICE NOTES 2075DWRR The 2075DWRR has the same basic refrigeration system as the 2075R with a few exceptions. • The compressor is a high efficiency Embraco EMU30HSC. • The electro-mechanical gas bulb is replaced with an electronic controller. The controller features a digital temperature display and control with two LED indicators and three touch pad buttons.
  • Page 18 • Under most conditions, the refrigerator will remain frost-free by clearing itself between refrigeration cycles. Because there is no thermostat bulb on the evaporator, like other U-Line refrigerators, the con- troller runs a 45 minute off-cycle for every 12 hours of clock time. The refrigerator will not cool during this off-cycle even if the refrigerator thermistor is calling for cooling.

During this phase change, a great amount of heat is rejected with the help of the condenser fan.
  • Page 33 2075DWRWC Design Features Performance • From the dryer, the refrigerant flows through the capillary tube which meters the liquid refrigerant to the evaporator. The pressure of the refrigerant is reduced to the evaporating or low side pressure. • The reduction of pressure on the liquid refrigerant causes it to boil or vaporize until it reaches satura- tion temperature.
  • Page 34 2075DWRWC Design Features Performance The top and bottom valve can never be open at the same time. After initial startup whichever compartment calls for cooling first, will have priority. Once the setpoint is achieved the other compartment will be cooled if necessary. When both compartments have reached setpoint and the compressor shuts off, the last bypass valve that was open will remain open for four minutes.

    2075DWRWC Design Features Performance 3 Drawers will not close properly • The drawer slides contain a self-closing feature which engages when the drawer is about 1 inch from being closed. At the point the closers engage, there may be some resistance. If this resistance is hard to overcome, try closing the drawers with more force a couple times and then try slowly again.
