the range of 3 gpm per ton. Minimum inlet condenser
water temperature is 65°F. Condenser piping must be in
accordance with all local and national codes. Condenser
piping components generally function identically to those
in the evaporator piping system. In addition, cooling tower
systems may include a manual or automatic bypass valve
that can alter water flow rate to maintain condensing
pressure. Well (city) water condensing systems should
include a pressure reducing valve and water regulating
valve. A pressure reducing valve should be installed to
reduce water pressure entering the condenser. This is
required only if water pressure exceeds nameplate
maximums. This is also necessary to prevent damage to
the disc and seat of the water regulating valve that can be
caused by excessive pressure drop through the valve.
