Abstract

Heat rejection devices, including cooling towers, condensers and closed circuit coolers, having side-mounted backward-curved centrifugal fans mounted on top of the device, above a fan plenum instead of a top-mounted axial fan. Heat rejection capability can be easily modified by adding or subtracting fans without impacting unit footprint. Also, the ability to handle higher static pressures allows for the use of a more densely packed heat exchanger in the same footprint unit, which will increase the unit performance.

Abstract

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 stream inlet located at a center point of each bottom bonnet.

Abstract

A system and method for increasing the refrigeration capacity of a direct expansion refrigeration system having a vapor separator and a vapor ejector. After the throttling process at the expansion device, the mixture of liquid and vapor enters the inlet separator. The vapor separator generates vapor to power the ejector through flashing of warm refrigerant liquid from a higher temperature and pressure to a lower pressure. The cooler refrigerant liquid then goes to the evaporator coil inlet. Furthermore, the system stabilizes the superheat of the outlet vapor and reduces fluctuations in outlet superheat caused by excess unevaporated liquid flowing from the outlets of the tubes due to maldistribution at the inlet.

Abstract

An air-cooled adiabatic heat exchanger for cooling fluids having tube bundles for receiving hot process and rendering cooled fluid, operating in three or four modes. In a dry mode, heat is exchanged with dry air drawn through the tube bundles by fans. In an adiabatic mode, air entering the heat exchanger is adiabatically pre-cooled by water-saturated adiabatic pads, while the tube bundles remain dry. In an evaporative mode, the adiabatic pads remain dry, and the tubes are wetted with evaporative cooling water. In an optional fourth mode, both the adiabatic pads and the tubes are wetted.

Abstract

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.

Abstract

A system and method for increasing the refrigeration capacity of a direct expansion refrigeration system having a vapor separator and a vapor ejector. After the throttling process at the expansion device, the mixture of liquid and vapor enters the inlet separator. The vapor separator generates vapor to power the ejector through flashing of warm refrigerant liquid from a higher temperature and pressure to a lower pressure. The cooler refrigerant liquid then goes to the evaporator coil inlet. Furthermore, the system stabilizes the superheat of the outlet vapor and reduces fluctuations in outlet superheat caused by excess unevaporated liquid flowing from the outlets of the tubes due to maldistribution at the inlet.

Abstract

A system and method for increasing the refrigeration capacity of a direct expansion refrigeration system having a vapor separator and a vapor ejector. After the throttling process at the expansion device, the mixture of liquid and vapor enters the inlet separator. The vapor separator generates vapor to power the ejector through flashing of warm refrigerant liquid from a higher temperature and pressure to a lower pressure. The cooler refrigerant liquid then goes to the evaporator coil inlet. Furthermore, the system stabilizes the superheat of the outlet vapor and reduces fluctuations in outlet superheat caused by excess unevaporated liquid flowing from the outlets of the tubes due to maldistribution at the inlet.

Abstract

A hybrid condenser or fluid cooler having an indirect heat exchange and a direct heat exchanger, in which tube circuits in the indirect heat exchanger are arranged parallel to the direction of air flow of a crossflow direct heat exchanger. The design features elongated fluid headers combined with multiple shortened circuits, resulting in a compact design that lowers the fluid pressure drop across the heat exchanger. This design creates an increased turbulence in relation to fluid flow, resulting in an increase in thermal performance.

Abstract

An 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 motorized valve in the compressor discharge piping 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 open one at a time. The discharge pressure regulating motorized valve simultaneously regulate the discharge pressure until the condenser coil has warmed up enough to maintain discharge pressure.

Abstract

A system and method for increasing the refrigeration capacity of a direct expansion refrigeration system having a vapor separator and a vapor ejector. After the throttling process at the expansion device, the mixture of liquid and vapor enters the inlet separator. The vapor separator generates vapor to power the ejector through flashing of warm refrigerant liquid from a higher temperature and pressure to a lower pressure. The cooler refrigerant liquid then goes to the evaporator coil inlet. Furthermore, the system stabilizes the superheat of the outlet vapor and reduces fluctuations in outlet superheat caused by excess unevaporated liquid flowing from the outlets of the tubes due to mal-distribution at the inlet.

Abstract

Heat rejection devices, including cooling towers, condensers and closed circuit coolers, having side-mounted backward-curved centrifugal fans mounted on top of the device, above a fan plenum instead of a top-mounted axial fan. Heat rejection capability can be easily modified by adding or subtracting fans without impacting unit footprint. Also, the ability to handle higher static pressures allows for the use of a more densely packed heat exchanger in the same footprint unit, which will increase the unit performance.
