Refrigeration System Components and Installation Practices

The star of the freezer means * = -6 ºC.

Refrigeration System Components

Evaporators

  • Types: Visible or buried.
  • Temperature Conservation: Limited space and evaporator size.
  • Apparatus Combination: Network hose and multiple computers (e.g., 2 evaporators, 2 tabs).
  • Single Computer Evaporator: More coils for the freezer, less cooling capacity.
  • Circuit Perimeter: Extended around doorways to prevent frost (highest leak potential).
  • Loop: Circulates oil from the crankcase for cooling.

The vacuum is up to 30 inches.
