    摘要： A method to reduce/prevent liquid refrigerant flooding in the compressor is disclosed herein. The method may include closing down the ETV when there is a risk of compressor flooding. The method may include closing down the ETV to a desired value when there is a risk of the compressor flooding. A failure to provide the superheated refrigerant vapor in a desired superheat temperature by the compressor may indicate a risk of the compressor being flooded by liquid refrigerant. The method may include measuring a refrigerant discharge temperature of the compressor, and closing down the ETV when a difference between the refrigerant discharge temperature of the compressor and a refrigerant saturate temperature is below a desired temperature threshold.

    摘要： Disclosed is a refrigeration circuit in which a scroll compressor is used as a compressor, an unsaturated fluorinated hydrocarbon refrigerant is used as a refrigerant, and an ether-based lubricant such as a polyalkylene glycol is used as a refrigeration machine oil, and wherein a wax-like solid material, which causes clogging of the refrigeration circuit or deterioration of the refrigeration performance, is prevented from being generated. Specifically, a wax-like solid material is prevented from being generated in a refrigeration circuit by adding a lubricant type component having no polyoxyalkylene structure such as an ester-based lubricant, an alcohol-based friction modifier, an olefin-based friction modifier, a polyolefin-based lubricant, an alkyl aromatic lubricant or a silicone-based lubricant, or a metal deactivation agent such as benzotriazole to an ether-based lubricant such as a polyalkylene glycol.

    摘要： A bypass factor of an evaporator is used to indicate when an air filter of an HVAC is clogged. The bypass factor represents the amount of air that is bypassed without direct contact with the evaporator. As the air filter clogs, the bypass factor decreases. The bypass factor can also be used for early detection of clogging of the air filter. A first bypass factor is calculated by using the temperature measurements, and a second bypass factor is calculated by using the airflow rate of the air. The difference between the two bypass factors determines the error. An increase in the error indicates that the air filter is clogged. A coefficient of performance of the evaporator can also be calculated to detect if the air filter is clogged. A decrease in the coefficient of performance indicates that the air filter is clogged.

    摘要： Systems and methods for improving the performance of dilution refrigeration systems include cryocondensation traps employed in the helium circuit of a dilution refrigerator may be modified to improve performance. A cryocondensation trap employs a cryocondensation surface having at least one temperature that preferably matches the temperature at which at least one contaminant freezes into a solid form from a gaseous form. A single trap with at least one continuous cryocondensation surface formed in a generally helical or spiral-like fashion with each region having a different temperature may be employed to trap a specific contaminant or set of contaminants. A single trap with multiple cryocondensation surfaces where each surface has a different temperature may be alternatively employed for the same purpose. To provide a temperature gradient in the cryocondensation trap, at least one region of the cryocondensation trap may be thermally coupled to a cold surface and/or a transfer tube.

    摘要： Systems and Methods of cooling heat generating electronics components are provided employing vapor compression refrigeration. The vapor compression refrigeration system (100) includes a condenser (104), at least one expansion structure (114, 116, 400), at least one evaporator (106, 108), and a compressor (122) coupled in fluid communication to define a refrigerant flow path, and allow the flow of refrigerant therethrough. The at least one evaporator is coupled to the at least one heat generating electronics component to facilitate removal of heat produced by the electronics component (110, 112). A portion of the expansion structure (114, 116, 400) is coated with a polytetraf luorethylene in the refrigerant flow path (430, 450) for inhibiting accumulation of material thereon. The polytetraf luorethylene (PTFE) coating has a thickness sufficient to inhibit accumulation of material in a pressure drop area (450) of the expansion structure without significantly changing a pressure drop characteristic of the pressure drop area.
