摘要： A method and apparatus for improving the rate of heat transfer between an evaporator of a refrigeration system and the environment surrounding the evaporator. In one embodiment, the evaporator is placed in thermal communication with the air of a data center where electronic equipment is operated therein. To improve the rate of heat transfer between the air and the evaporator, water is evaporated into the air before it flows over the evaporator coils. As a result, when the humidified air flows over the cold evaporator coils, a portion of the water vapor in the air condenses on the evaporator, thereby wetting the evaporator coils. The wetted surfaces of the evaporator coils improve the rate of heat transfer between the air and, ultimately, the refrigerant passing through the evaporator. In one embodiment, a humidifier having a water atomizer may be used for spraying and dispersing water into the air.

摘要： A method and apparatus for maintaining a relatively constant temperature of a working fluid in an evaporator of a refrigeration system by providing a constant volumetric displacement compressor and a heat exchanger for exchanging heat between the high pressure and low pressure portions of a refrigeration circuit to superheat, and hold substantially constant, the temperature of the refrigerant entering the compressor. In doing this, the pressure of the refrigerant in the low pressure portion of the circuit, including the evaporator, and the mass flow rate of the refrigerant remain substantially constant. As a result, the temperature of the saturated refrigerant in the evaporator remains substantially constant.

摘要： A transcritical vapor compression system includes a fluid circuit circulating a refrigerant in a closed loop. The fluid circuit has operably disposed therein, in serial order, a first compressor, an intercooler, a second compressor with a variable capacity, a first heat exchanger, an expansion device and a second heat exchanger. The first compressor compresses the refrigerant from a low pressure to an intermediate pressure. The second compressor compresses the refrigerant from the intermediate pressure to a supercritical pressure. The first heat exchanger is positioned in a high pressure side of the fluid circuit. The second heat exchanger is positioned in a low pressure side of the fluid circuit. The expansion device reduces the pressure of the refrigerant from a supercritical pressure to a relatively lower pressure. Cooling means cools the refrigerant within one of the compressors.

摘要： In a given design of a refrigeration system, the present invention provides a method for reducing the charge of the refrigerant flowing through the refrigeration system. The refrigeration system includes a fluid conduit through which a flammable refrigerant circulates. The fluid conduit couples, in serial order, a compressor, a first heat exchanger, an expansion device, and a second heat exchanger. The conduit defines an interior diameter, an interior surface, and a given friction factor range. The method includes the steps of reducing the interior diameter of the conduit to thereby reduce the system design refrigerant charge, and coating the interior surface of the reduced diameter conduit with a coating composition to thereby reduce the surface roughness of the interior surface and provide a friction factor for the reduced diameter conduit that is substantially within the given friction factor range.

摘要： A method of operating a vapor compression system, the vapor compression system defining a closed fluid circuit in which a refrigerant is circulated and having operably disposed therein, in serial order, a compressor, a high pressure heat exchanger, an expansion device and a low pressure heat exchanger. The method includes applying a variable thermal load on a first one of the heat exchangers, monitoring the thermal load placed on the first heat exchanger and controlling the operation of the system to limit the thermal load placed on the first heat exchanger when the thermal load exceeds a predetermined value. A heat exchange subsystem employed to limit the thermal load may include reducing the flow of a heat exchange medium over the heat exchanger or to recirculate the heat exchange medium in a manner which reduces the thermal load on the heat exchanger.

摘要： A hydrocarbon cooling system including a housing having a substantially rectangular base defining a diagonal, a front wall defining a first air inlet, a back defining a first air outlet, and a pair of side walls. The cooling system includes a condenser mounted within the housing adjacent the first air inlet; a compressor; an evaporator; and a fan mounted within the housing and defining an axis. The fan is positioned such that a vertical plane aligned along the axis defines a first a non-perpendicular angle relative to a second vertical plane aligned perpendicular to the back of the housing. The fan creates a first horizontal airflow path, which enters the housing through the first air inlet and exits the housing through the first air outlet. The first horizontal airflow path induces a second horizontal airflow, which moves around the housing along a line substantially parallel to the diagonal.
