摘要： In a cooling apparatus comprising a device for (pre)cooling the liquid coolant by means of its limited expansion, the invention provides a method of reduced energy consumption by (also) utilising for cooling, at least temporarily, the (pre)cooled liquid coolant as a liquid heat carrier, by causing at least a partial amount of the coolant to flow, by maintaining its liquid state without evaporation, through at least one heat exchanger (10). The method is preferably performed in an apparatus wherein the device for (pre)cooling the liquid coolant comprises two identical liquid recipients (1, 2) the upper inner space sections of which are alternately connectable to a phase separator (3), that is also connected to a collector conduit (50) of a liquid collector (9). The liquid recipients (1, 2) are also alternately connectable to a common supply conduit (54) which is, via a changeover valve (22), connected to the collector conduit (50) of the liquid collector (9), and to a common discharge conduit (51) that leads to a (pre)cooled liquid outlet (LO) of the device. A vapour outlet of the phase separator (3) is connected to a displacement pump (4) and a vapour inlet (VI) of the device. The common discharge conduit (51) of the liquid recipients (1, 2) is also connected, via a coolant pump (5), a heat exchanger (10), and a controlled closing valve (27), to the changeover valve (22) so that in typical modes of operation, the positive circulation of the liquid coolant within the device is allowed for.

摘要： A refrigeration chiller (10) employs a centrifugal compressor (12) the impellers (42, 44) of which are mounted on a shaft (48) which it itself mounted for rotation using rolling element (53) bearings (52) lubricated only by the refrigerant which constitutes the working fluid of the chiller system (10). Apparatus is taught for providing liquid refrigerant to (1.) the bearings (25) immediately upon chiller start-up, during chiller operation and during a coastdown period subsequent to shutdown of the chiller (10) and (2.) the drive motor (40) of the chiller's compressor (12) for motor cooling purposes. By use of a variable speed-driven motor (40) to drive the compressor (12), optimized part load chiller performance is achieved in a chiller which does not require or employ an oil-based lubrification system.

摘要： The refrigeration system (10) includes a compressor-pump unit and a liquid pump (21) between a condenser (18) and an expansion device (12) which improves efficiency of the refrigeration system by increasing the pressure of, thus subcooling, the liquid refrigerant. The liquid pump (21) and the compressor (26) are driven by a single driving device (24) and, in this regard, are coupled to a single shaft of a driving device (24), such as a belt-drive, an engine, or an electric motor (40). While the driving device (24) may be separately contained, in a preferred embodiment, the liquid pump (21), the compressor (26), and the driving device (24) (i.e., an electric motor (40)) are contained within a single sealable housing (30) having a pump (21) and driving device (24) cooling paths to subcool liquid refrigerant discharged from the liquid pump (21) and to control the operating temperature of the driving device (24).

摘要： The present inventions are intended to improve heat efficiency of a refrigeration system having plural refrigerating cycles of different evaporating or condensing temperatures typically used in breweries.
Each of main lines of different evaporating temperatures are connected with each of suction lines to a compressor respectively, to enable the system to save energy and to establish a back-up system of compressors.
A different condensing temperature system having a common refrigerant source is provided with refrigerant transferring means to transfer refrigerant from an refrigerant excess cycle to an refrigerant insufficiency cycle.
The refrigerating cycles are arranged in parallel and the evaporators are connected to form a liquid path, through which a liquid stream flows in series to be chilled in the evaporators, as well as to form a refrigerant path for a refigerant stream of each rerigerating cycle, individually, and further are arranged in order from a high evaporating temperature of refrigerant to low one along the liquid path from the upstream to the downstream.

摘要： A compressor for vapor-compression cooling systems, which exploits the properties of acoustic resonance in fluids for fluid compression, and provides a discharge pressure which can be varied during operation in response to changing operating conditions, thereby providing an oil-less compressor and reducing the compressor's energy consumption. The thermoacoustic properties of standing acoustic waves are exploited to provide a refrigerant subcooling system which is contained within the compressor. Refrigerant subcooling occurs when heat exchange is provided between the refrigerant and a heat pumping surface, which is exposed to the standing acoustic wave within the compressor. Acoustic energy can be provided by either a mechanical driver, or by direct exposure of the fluid to microwave and infrared energy, including solar energy. Inlets (4) and outlets (6) arranged along the chamber (2) provide for the intake and discharge of a fluid refrigerant, and can be provided with optional reed valve arrangements, so as to increase the compressor's compression ratio. The performance of the compressor can be optimised by a control circuit which holds the wavelength of the standing wave constant, by varying the driving frequency in response to changing operating conditions.
