Apparatus for staged startup of air-cooled low charged packaged ammonia refrigeration system includes motorized valves on condenser coil inlets, a main compressor discharge motorized valve, a bypass pressure regulator valve in the main compressor piping, check valves on the condenser outlets and speed control of the condenser fans. The condenser inlet motorized valves provide precise control of gas feed to the condensers, so pressure can build without collapsing the oil pressure. The condenser coil outlet contains inline check valves to prevent liquid backflow when a coil is isolated. The compressor discharge line contains a single motorized valve for regulating discharge pressure at start-up. The motorized valve in the compressor discharge piping also includes a bypass with a mechanical pressure regulator to allow precise regulation at the minimum discharge pressure. Once discharge pressure rises above the minimum setpoint, the condenser inlet solenoid coils will open one at a time. The discharge pressure regulating motorized valve will simultaneously regulate the discharge pressure until the condenser coil has warmed up enough to maintain discharge pressure.

A new heat exchange tube fin design in which a plurality of arrowhead shapes are pressed into or embossed onto each fin, the arrowhead shape defined by two intersecting wedge sections. The pressed arrowhead shapes are grouped into nested pairs, and one of the arrowheads in a pair is pressed as a positive relative to the fin plane and the other of the pair is pressed as a negative relative to the fin plane. The arrowhead pairs are placed in rows parallel to the air flow direction and arrowhead pairs in one row are preferably staggered relative to the arrowhead pairs in the adjacent row along the fin in the air flow direction.

ADVANCED LARGE SCALE FIELD-ERECTED AIR COOLED INDUSTRIAL STEAM CONDENSER
Large scale field erected air cooled industrial steam condenser having heat exchanger panels independently loaded into and supported in a heat exchange frame section. A bottom bonnet runs along the bottom length of each heat exchanger panel for delivering steam to the bottom end of condenser tubes in the heat exchange panel and for receiving condensate formed in those same tubes. The tops of the tubes are connected to a top bonnet. Uncondensed steam and non-condensables are drawn into the top bonnet from the condenser tubes. A steam distribution manifold is suspended from the heat exchange section frame perpendicular to the longitudinal axis of the heat exchange panels and beneath a center point of the heat exchange panels and delivers steam to each heat exchange panel via a single steam inlet located at a center point of each bottom bonnet.
