Titan Central Chillers
6.1 REFRIGERATION SYSTEM
A. COMPRESSOR: Hermetic or semi-hermetic compressors
take low pressure/low temperature refrigerant gas and
compress the gas into high pressure/high temperature
gas.
B. AIR-COOLED CONDENSER: The air cooled condenser
removes BTU's from the compressed refrigerant gas. The
action causes the gas to "condense" into a liquid state
still under high pressure. Air flow across the condenser is
achieved via a motor driven fan assembly. The air-cooled
condenser is located outdoors on most Titan central
chillers. Models using air-cooled condensers are
designated with a TI-A in the model number.
C. WATER-COOLED CONDENSER: The water
cooled condenser removes BTU's from the
compressed refrigerant gas. The action causes
the gas to "condense" into a liquid state still under
high pressure. Water flow across the condenser is
provided by an external source, typically the plant's
tower water. In some cases, city water is used
also. Models using water-cooled condensers are
designated with a TI-W in the model number.
C. FILTER-DRIER: The filter-drier removes contaminants
and moisture from the liquid refrigerant (figure 6.2C).
D. LIQUID LINE SOLENOID VALVE:
instrument, this valve closes when the compressor cycles
off to prevent refrigerant liquid from migrating to the
evaporator. The valve opens when the compressor cycles
on.
E. REFRIGERANT SIGHT GLASS: The refrigerant sight
glass indicates refrigerant charge and moisture content.
Refrigerant charge is determined by a clear liquid flow.
Bubbles indicate low refrigerant. Moisture content is
indicated by the color of the element. Element color is
normally green. If the color of the element is chartreuse or yellow, the system has
been contaminated with moisture. In such case, the filter-drier must be replaced.
The replacement of the filter-drier must be completed by a qualified refrigerant
service technician.
F. EXPANSION VALVE: The expansion valve throttles flow of refrigerant liquid into
the evaporator and creates a pressure drop in the refrigerant system that allows the
liquid refrigerant to "boil off" inside the evaporator.
G. EVAPORATOR: The evaporator is a brazed plate heat exchanger where the
refrigerant liquid is allowed to evaporate (boil off) to absorb heat (BTU) from the
process fluid. As the heat is absorbed, the process fluid is chilled.
