Large scale field erected air cooled industrial steam condenser having 10 heat exchanger bundles per cell arranged in five pairs in a V-shape, each heat exchanger bundle having four primary heat exchangers and four secondary heat exchangers in which each secondary heat exchanger is paired with a single primary heat exchanger. Four primary condensers are arranged such that the tubes are horizontal, while the inlet steam manifolds at one end of the tubes are perpendicular to the primary condenser tubes, i.e., parallel to the transverse axis of the bundle. Steam enters the small inlet steam manifolds from below. Cross-sectional dimensions of the tubes are 200 mm wide with a cross-section height of less than 10 mm with fins that are 10 mm in height, arranged at 9 to 12 fins per inch.

A dehumidifier is provided, the dehumidifier includes a housing, and a condenser and an evaporator arranged inside of the housing that are each formed into a generally circumferentially extending C shape and arranged to be generally coaxial and aligned with one another. A compressor and a fan are each centrally located in the housing, with the fan located above the compressor. A collection pan is located under the evaporator, and a water tank is located above the condenser, evaporator, and the compressor. A pump is provided to direct the collected water to the water tank.

An apparatus for cooling a computer system includes a primary cooling loop. The primary cooling loop includes an evaporator configured to cool at least a component of the computer system, an ambient cooled condenser connected to the evaporator, a first pump to provide a coolant flow within the cooling loop, a pressure regulator configured to maintain a selected pressure in the primary cooling loop, and a controller responsive to changes in outdoor ambient conditions and an amount of heat dissipated by the computer system and configured to dynamically adjust the pump and pressure regulator in response thereto.

A condenser having passages of varying geometry for cooling of fluid. The condenser apparatus includes substantially parallel tubes each defining a channel and having an inlet at a first end and an outlet at a second end, the first end having a greater hydraulic diameter than the second end. Inlet and outlet manifolds are provided. The tubes may be oriented substantially vertically with the inlets above the respective outlets. A heat exchanger core comprises the tubes and substantially horizontally oriented fin material connecting the tubes. The tubes may receive a relatively higher temperature vapor or vapor and liquid mixture into the inlets of the tubes, around the tubes coolant flows substantially horizontally to remove heat from the tubes, and relatively cooler saturated liquid is discharged from the outlets. In one embodiment, the tube's channel splits into multiple channels to reduce the hydraulic diameter and increase the surface area ratio.

During a normal operation, a refrigeration cycle device is switched to a refrigerant circuit in which heat contained in a high-pressure refrigerant flowing out of an interior radiator is stored in a heat storage member. When frost is formed on an evaporator, the refrigeration cycle device is switched to another refrigerant circuit in which the exterior heat exchanger is heated and defrosted using heat stored in the heat storage member as a heat source. The heat storage member uses a material formed by adding W (tungsten) as an additive to VO.sub.2 (vanadium dioxide) which is a transition metal oxide having a property of a phase transition between a metal and an insulator. The heat storage member effectively stores or dissipates heat depending on a temperature zone of the refrigerant, thereby suppressing an increase in energy consumption of a compressor.

A refrigerator is provided herein that includes a cabinet defining a refrigerated compartment and a machine compartment. A compressor is disposed within the machine compartment and adapted to compress a refrigerant within a refrigerant line. A heat exchanger is positioned in communication with the compressor and is adapted to reject heat from a refrigerant into the machine compartment. A fan is disposed between the heat exchanger and compressor. The fan is adapted to draw air from an area adjacent the machine compartment and through the heat exchanger. A funnel is disposed between the heat exchanger and the fan and directs air toward the fan. A tunnel is disposed between the fan and the compressor and directs forced air from the fan toward the compressor.

An air conditioner includes a housing, at least one evaporator air mover and at least one condenser air mover, an evaporator positioned within the housing in front of the evaporator air mover, and a non-linear condenser positioned within the housing behind the evaporator air mover. The condenser is arranged such that a body of the condenser is substantially perpendicular to the body of the evaporator.

This turbo chiller includes a shell-and-tube condenser; a header along a length direction of a shell is installed on a refrigerant inlet of the condenser, and openings are formed at least on both end portions of the header in the length direction, which allows high-temperature and high-pressure refrigerant gas from a compressor to be smoothly and evenly distributed to both length-direction end areas in the shell of the condenser through the header.

A refrigerator includes a cabinet that defines a storage space and a machine compartment that accommodates a compressor, a blow fan, and a condenser. The condenser is curved along front, rear, and side surfaces of the machine compartment. The condenser includes a first header disposed at a first end of the condenser, a second header disposed at a second end of the condenser, tubes that connect the first header and the second header to each other, an input connection portion that extends from the first header toward the second header and is configured to supply refrigerant to the first header, and an output connection portion that extends from the first header toward the second header and is spaced apart from the input connection portion. The output connection portion is configured to receive the refrigerant discharged from the first header.

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.
