摘要： A refrigeration system suitable for use in household refrigerators having a fresh food compartment, a freezer compartment and an intermediate temperature compartment is provided. The system includes a first expansion throttle, a first evaporator for providing cooling to a freezer compartment, first, second and third compressors, a condenser, a second expansion throttle, a second evaporator for providing cooling to a fresh food compartment, a third expansion throttle, and a third evaporator for providing cooling to an intermediate compartment. All the above elements are connected in series, in that order, in a refrigerant flow relationship. A first phase separator connects the second evaporator to the third expansion throttle in a refrigerant flow relationship and provides intercooling between the second and third compressors. A second phase separator connects the third evaporator to the first expansion throttle in a refrigerant flow relationship and provides intercooling between the first and second compressors. An accumulator is connected between the first evaporator and the first compressor to regain lost cooling capacity in the event liquid refrigerant is discharged from the first evaporator.

摘要： A refrigeration system includes a compressor, a condenser, an expansion throttle, an evaporator and a control valve. All of the above elements are connected in series, in that order, in a refrigerant flow relationship. During periods in which the compressor initiates a passive defrost mode, control valve disposed within the conduit connecting the compressor and the evaporator remains open. Liquid refrigerant, by force of gravity, drains from the bottom of evaporator through the conduit to the compressor. This draining liquid refrigerant is evaporated by the hot compressor, flowing upward to the cold evaporator surfaces and condensing. The condensation releases latent heat of vaporization and heats the surface of the evaporator melting ice buildup thereon. In another embodiment, the refrigeration system further includes a bypass line connecting the compressor to the top of the evaporator. The inclusion of the bypass line allows the flow of the evaporated refrigerant to flow directly from the compressor to the evaporator through the bypass line, and the flow of liquid refrigerant to flow directly from the evaporator to the compressor through the conduit, such that no counter-current liquid and vapor flow within one conduit is required.

摘要： Pulse width modulation is used to control the flow rate through a solenoid expansion valve in a refrigeration system using a simple vapor compression cycle. The refrigeration cycle includes a phase separator which receives two phase refrigerant from the condenser and supplies liquid refrigerant to the pulse width modulated solenoid valve. A liquid level sensor is disposed in the phase separator, and a controller for controlling the duty cycle of the pulse width modulated solenoid valve is provided to receive input from the liquid level sensor. The liquid level sensor can be of the type which provides a continuously variable signal as a function of liquid level, or it can be a liquid level switch which controls valve duty cycle on the basis of whether the phase separator liquid level is above or below a set level. Alternatively, two liquid level switches can be provided.

摘要： Low thermal conductivity insulation for refrigerators and the like is produced by blowing a resinous foam in an inert (e.g., nitrogen) atmosphere with a mixture of carbon dioxide and a low thermal conductivity inert gas such as krypton or xenon. The foam is then sealed in a gas-impervious enclosure and carbon dioxide is removed therefrom, typically by inclusion in said enclosure of a solid material reacted therewith such as an alkaline reagent. The final partial pressure of the low thermal conductivity gas in the enclosure is in the range of about 20-200 torr, and the total pressure is up to 110% of said partial pressure.

摘要： An excess liquid refrigerant accumulator for multievaporator refrigeration systems is provided. Under some operating conditions, the lowest temperature evaporator of a multievaporator system may discharge some liquid refrigerant rather than only vapor refrigerant. This liquid discharge creates a loss of cooling capacity. A receptacle connected to the exit of the lowest temperature evaporator accumulates the liquid. By locating the receptacle within the cooled compartment, the cooling capacity which would otherwise be lost, is regained.
