Abstract

<P>PROBLEM TO BE SOLVED: To use an environmentally-friendly refrigerant as a refrigerant of a single-refrigerant refrigerator. <P>SOLUTION: In the single-refrigerant refrigerator, a mixture of nitrous oxide and an HC refrigerant is used as the refrigerant. The HC refrigerant is ethane. In the refrigerator, a high-temperature high-pressure gaseous mixed refrigerant discharged from a compressor 1 is discharged to a condenser 2 from a discharge side pipe 6. The refrigerant discharged to the condenser 2 is heat-dissipated in the condenser 2, and is condensed and liquefied. The pressure of condensed and liquefied refrigerant is reduced by a pressure-reducer 3 and flows into an evaporator 4, and evaporates and vaporizes to cool the surroundings. The refrigerant vaporizing in the evaporator returns to the compressor 1 from a suction side pipe 7. <P>COPYRIGHT: (C)2004,JPO

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a one-way refrigeration ultra-low temperature refrigeration apparatus.
[0002]
[Prior art]
Conventionally, an ultra-low-temperature refrigeration apparatus has been used to generate an ultra-low temperature of −60 ° C. to −90 ° C. or less. This ultra-low temperature refrigeration system includes a one-way refrigeration system (a single-unit refrigeration system) and a multi-stage refrigeration system such as a binary refrigeration system including a high-temperature side refrigeration circuit and a low-temperature side refrigeration circuit.
[0003]
[Problems to be solved by the invention]
An object of the present invention is to use an environmentally friendly refrigerant as a refrigerant of a one-way refrigeration apparatus.
[0004]
[Means for Solving the Problems]
The present invention is characterized in that a mixture of nitrous oxide and HC refrigerant is used as a refrigerant in a one-way refrigeration apparatus.
[0005]
Further, the present invention is characterized in that a mixture of nitrous oxide and ethane is used as a refrigerant in a one-way refrigeration apparatus.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
A first embodiment of the present invention will be described with reference to FIG.
[0007]
In FIG. 1, reference numeral 1 denotes a compressor, 2 denotes a condenser, 3 denotes a decompression device for a main capillary tube, and 4 denotes an evaporator.
[0008]
The discharge-side pipe 6 of the compressor 1 is connected to the condenser 2, and the condenser 2 is connected to the capillary tube pressure reducing device 3, which is connected to the evaporator 4. This evaporator is connected to the suction pipe 7 of the compressor 1.
[0009]
A refrigerant that is a mixture of nitrous oxide and HC refrigerant is sealed in the refrigeration circuit. The HC refrigerant is, for example, ethane.
[0010]
In the refrigeration apparatus configured as described above, the high-temperature and high-pressure gaseous mixed refrigerant discharged from the compressor 1 is discharged from the discharge-side pipe 6 to the condenser 2. The refrigerant discharged to the condenser 2 is radiated by the condenser 2 to be condensed and liquefied. The condensed and liquefied refrigerant is decompressed by the decompression device 3 and flows into the evaporator 4, where it evaporates and evaporates to cool the surroundings. The refrigerant evaporated in the evaporator returns to the compressor 1 from the suction pipe 7.
