Refrigeration System

Basic components of a freezer are:
1. The compressor located in the machine

compartment.

2. The condenser that is foamed to the outer walls of the

cabinet.

3. The evaporator located on the inside left wall of the

food compartment.

4. The capillary tube connects the output end of the drier

to the input of the evaporator.

5. The filter-drier located in the machine compartment.

6. The suction line connects the output of the

evaporator to the input side of the compressor.
