thermostat contacts close, the current flow
through the anticipator is insignificant because
the contacts of the thermostat offer less
resistance to current flow than the anticipator
resistance, so the anticipator is de-energized.
REFRIGERANT LINES AND PIPING
Because of the progress made in this field,
construction has become much simpler. Since
precharged lines are in everyday use, the
problems of installation are being eliminated.
However, pay particular attention to neatness
and cleanliness when you are installing
support brackets (hangers) and insulation.
Figure 14-21 shows a schematic piping
diagram of a typical commercial refrigeration
system. This system has a roof-mounted
air-cooled condenser and two motor com-
pressors. Each motor compressor has a
suction and a liquid header and is connected
to six refrigerant lines. A detailed view of an
oil separator installation is shown in figure
