REFRIGERATION SYSTEM LAYOUT
Product must be pre-frozen for low temp
applications . For medium temperature
applications products must be pre-chilled .
The evaporator is dual circuited . Circuit 1 is
the bottom section and Circuit 2 is the top
section . In Figure B, lefthand circuit is shown .
The flow is described as the following:
Cap tube is feeding the bottom section of the
coil . Once the refrigerant passes through the
evaporator, refrigerant goes out to the suction
line to the compressor .
The discharge line runs through the evaporation
pan to increase the water temperature, located
in the top level of the evaporation pan . At
the same time, refrigerant temperature drops,
increasing system capacity .
