Abstract: A refrigeration system has a primary refrigeration circuit with an evaporator, a network driver, a condenser, and an expansion valve. These components are connected in series by a primary refrigerant line. The system also has a secondary refrigeration circuit which includes the evaporator, the condenser, and a bypass valve conncted in series by a secondary refrigerant line. The secondary refrigerant line is in fluid communication with the primary refrigerant line and has a network driver bypass line bridging an inlet and an outlet of the network driver. The network driver bypass line incorporates the bypass valve. A controller selectively de-activates the primary refrigeration circuit by de-activating the network driver and activates the secondary refrigeration circuit by opening the bypass valve.

Abstract: An air conditioning system having a cooling mode and a free-cooling mode is provided. The system includes a refrigeration circuit, two pressure sensors, a controller, and a pump starting sequence resident on the controller. The refrigeration circuit includes a compressor and a pump. The first pressure sensor is at an inlet of the purnp, while the second pressure sensor is at an outlet of the pump. The controller selectively operates in the cooling mode by circulating and compressing a refrigerant through the refrigeration circuit via the compressor or operates in the free-cooling mode by circulating the refrigerant through the refrigeration circuit via the pump. The pump starting sequence cycles the pump between an on state and an off state based at least upon a differential pressure determined by the controller from pressures detected by the pressure sensors.

Abstract: Disclosed is a refrigerator having a noise reduction structure. According to the refrigerator, a branch pipe for reducing the intensive noise occurring from an impeller part is provided to a discharge pipe connected so that the refrigerant is discharged in a direction of a condenser from the impeller part. Therefore, the traveling sound wave of the noise traveling along the discharge pipe and the reverse sound wave traveling toward the branch pipe provided to the outer periphery of the discharge pipe meet each other, so that the both sound waves are cancelled to reduce the noise.

Abstract: A system and method for controlling the temperature of a process tool uses the vaporizable characteristic of a refrigerant that is provided in direct heat exchange relation with the process tool. Pressurized refrigerant is provided as both condensed liquid and in gaseous state. The condensed liquid is expanded to a vaporous mix, and the gaseous refrigerant is added to reach a target temperature determined by its pressure. Temperature corrections can thus be made very rapiday by gas pressure adjustments. The process tool and the operating parameters will usually require that the returning refrigerant be conditioned and processed for compatibility with the compressor and other units, so that cycling can be continuous regardless of thermal demands and changes.

Abstract: The present invention relates generally to an evaporator and more specifically to an evaporator having an evaporating chamber (110') equipped with drainage means (160'). The drainage means (160') drain accumulated liquid from the evaporator's lower parts and include an external expansion driven injector and/or an external pump. The evaporator according to the invention can be used e.g. in a heat exchanger, e.g. in a heat pump system or air condition system, and said vacuum driven injector can be integrated with an expansion means (140') of the heat exchanger. The invention also relates to a condenser to be used together with said evaporator in a heat exchanger of the plate type realising an integrated superheater/supercooler. This is accomplished by the definition and use of delimited interacting zones through which the cooling medium circulates under heat exchange with itself.

Abstract: A refrigeration system (40) including a compressor (12), a condenser (14), an expansion device (16) and an evaporator (18) connected in a closed circuit through which a refrigerant is circulated. Liquid refrigerant is injected between an outlet of the compressor and an inlet of the condenser using a vacuum generator (44) in which the vacuum is created by the geometry of the device and the dynamic properties of fluid flow therein, thereby allowing the refrigerant to be cooled at a temperature close to its saturation temperature when it enters the condenser without the need for a costly pump having moving parts. The vacuum may be produced by vortex flow of the superheated vapor output of the compressor, by flow of the superheated vapor through the throat of a venturi device, or in any other comparable manner. The refrigeration system may employ a single refrigerant or a mixture of refrigerants such as R-134a, R-32 and R-125.

Abstract: Compressors (1) supply a primary air-cooled condenser (4) which is followed by an indirect heat exchanger (6), a liquid receiver (8) and a second indirect heat exchanger (10) acting as a refrigerant sub-cooler. A pump (12) supplies sub-cooled refrigerant to remote cooling devices (15, 18) and a bypass line (19) is provided to recirculate a proportion of the refrigerant through the sub-cooler (10), thereby maintaining a flow of cooled refrigerant in the distribution network even when there is no cooling demand. The distribution and return pipes are enclosed within a common temperature environment provided by a thermal insulation sheath (14). Secondary cooling circuits (21) operate off-peak to create pumpable ice slurry in an ice store (23) which is used to cool the indirect heat exchanger (6). The heat exchanger (6) acts as an additional condenser under hot ambient conditions. Systems are also described in which the ice store is eliminated with direct heat exchange between the primary and secondary cooling systems, and in which the cooling devices (15, 18) are supplied through a cooling loop containing an indirectly-cooled non-hydrocarbon heat exchange medium.

Abstract: An apparatus and associated method for discharging a fluid (20) and a liquid (30, 34) separated from the fluid (20) from an outlet chamber (16) of a heat exchanger (11,15). The outlet chamber (16) is configured to collect the separated liquid (30, 34). The apparatus includes a plate (36) that is positionable in the outlet chamber (16) adjacent to the exit surface (17) to form a channel (38) between the plate (36) and the exit surface (17). The plate (36) is configured to protrude over the outlet tube opening (19) so that the fluid (20) flowing through the outlet chamber (16) and into the outlet opening (19) pulls the liquid (30, 34) collected in the outlet chamber (16) through the channel (38) and out through the outlet opening (19) with the fluid (20). Because of the plate (36), the fluid (20) exiting through the outlet opening (19) must flow through a decreased area. This decreased area creates a low pressure region. The low pressure region draws the collected liquid (30, 34) through the channel (36) and discharges it through the outlet opening (19) with the fluid (20).
