Definitions
- the present invention includes a refrigerant circuit having a gas-liquid separator, and uses CO refrigerant as a high critical pressure.
- the present invention relates to a refrigeration apparatus that performs a two-stage compression and two-stage expansion refrigeration cycle.
- Patent Document 1 discloses an air conditioner that has a refrigerant circuit including a gas-liquid separator and performs a two-stage compression two-stage expansion refrigeration cycle.
- the refrigerant circuit of the air conditioner is provided with a compressor, a first heat exchanger, a first expansion valve, a gas-liquid separator, a second expansion valve, and a second heat exchanger.
- the compressor may constitute a two-stage compression compressor in which a low-stage compression mechanism and a high-stage compression mechanism are connected by a drive shaft.
- the gas-liquid separator is configured to be able to separate the intermediate-pressure gas-liquid two-phase refrigerant into liquid refrigerant and gas refrigerant.
- the refrigerant discharged from the compressor flows through the first heat exchanger.
- the refrigerant dissipates heat to the air.
- the refrigerant that has passed through the first heat exchanger is reduced to an intermediate pressure when passing through the first expansion valve, and then flows into the gas-liquid separator.
- the gas-liquid separator the gas-liquid two-phase refrigerant having an intermediate pressure is separated into a gas refrigerant and a liquid refrigerant.
- the liquid refrigerant separated by the gas-liquid separator flows through the second heat exchange after being depressurized to a low pressure when passing through the second expansion valve.
- the refrigerant absorbs heat from the air and evaporates. As a result, the room is cooled.
- the refrigerant that has passed through the second heat exchanger is sucked into the compressor and compressed to an intermediate pressure by the low-stage compression mechanism.
- the refrigerant discharged from the low-stage compression mechanism is mixed with the gas refrigerant separated by the gas-liquid separator. That is, in this air conditioner, so-called intermediate pressure gas injection is performed in which the intermediate pressure gas refrigerant is mixed with the refrigerant discharged from the low-stage compression mechanism. Thereafter, the refrigerant is compressed to a high pressure by the high-stage compression mechanism and discharged again from the compressor.
- Patent Document 2 describes that the refrigerant circuit is filled with CO refrigerant and the above-described intermediate pressure gas
- An air conditioner that performs injection is also disclosed.
- a so-called supercritical cycle is performed in which the refrigerant discharged from the compressor is set to a critical pressure or higher.
- Patent Document 1 JP-A-7-110167
- Patent Document 2 Japanese Patent Laid-Open No. 2001-241797
- the refrigerant after being compressed and dissipated by heat exchange may still be at critical pressure in the gas-liquid separator.
- a critical pressure critical state
- only the gas refrigerant cannot be sent to the intermediate pressure refrigerant of the compressor, and the above-described intermediate pressure gas injection cannot be performed. Therefore, there was a problem that the desired intermediate gas injection effect could not be obtained and the COP of the air conditioner was reduced.
- the present invention has been made in view of power, and the object thereof is to use a CO refrigerant.
- the first invention provides a compressor (30) in which a low-stage compression mechanism (34) and a high-stage compression mechanism (35) are coupled to each other by a drive shaft (33), and an intermediate A gas-liquid separator (15) for gas-liquid separation of the pressurized refrigerant
- a compressor (30) having a low-stage compression mechanism (34) and a high-stage compression mechanism (35) is provided.
- the following two-stage compression and two-stage expansion refrigeration cycle is performed.
- the refrigerant compressed to the critical pressure by the high-stage compression mechanism (35) radiates heat in, for example, an indoor heat exchanger, and then is reduced to an intermediate pressure before flowing into the gas-liquid separator (15). .
- the intermediate pressure refrigerant is separated into a gas refrigerant and a liquid refrigerant.
- the liquid refrigerant is depressurized to a low pressure, evaporates by, for example, outdoor heat exchange, and sucked into the low-stage compression mechanism (34).
- This refrigerant is compressed to an intermediate pressure by the low-stage compression mechanism (34).
- the gas refrigerant separated by the gas-liquid separator (15) is introduced into this refrigerant.
- the intermediate pressure gas injection as described above is performed.
- the refrigerant is compressed to a high pressure (critical pressure) by the high-stage compression mechanism (35).
- the intermediate pressure refrigerant in the gas-liquid separator may be at a critical pressure.
- the refrigerant cannot be separated into the gas refrigerant and the liquid refrigerant in the gas-liquid separator, and the intended intermediate pressure gas injection cannot be performed. Therefore, in the present invention, the volume ratio of the high-stage compression mechanism (35) to the low-stage compression mechanism (34) is set larger than 0.8. That is, when the volume ratio is less than 0.8, the displacement volume of the high-stage compression mechanism (35) is relatively small with respect to the displacement volume of the low-stage compression mechanism (34).
- the pressure of the intermediate pressure refrigerant increases, and the refrigerant in the gas-liquid separator (15) may exceed the critical pressure.
- the pressure of the refrigerant in the gas-liquid separator (15) can be set to the subcritical pressure. Therefore, in the present invention, the refrigerant in the gas-liquid separator (15) can be reliably separated into the gas refrigerant and the liquid refrigerant, and the desired intermediate pressure gas injection effect can be obtained.
- the volume ratio is 1.3 or more, the displacement volume of the high-stage compression mechanism (35) is relatively larger than the displacement volume of the low-stage compression mechanism (34). As a result, it is not possible to ensure a sufficient amount of refrigerant sucked by the high stage compression mechanism (35), leading to a reduction in compression efficiency of the compressor (30). On the other hand, in the present invention, the volume ratio is made smaller than 1.3. Therefore, the amount of refrigerant sucked by the high-stage compression mechanism (35) can be sufficiently secured, and the refrigerant can be efficiently compressed in two stages.
- a second invention is characterized in that, in the first invention, the volume ratio is in the range of 0.9 or more and 1.1 or less.
- the high-stage compression mechanism (with respect to the displacement volume of the low-stage compression mechanism (34) (
- the volume ratio of the displacement volume of 35) is in the range of 0.9 or more and 1.1 or less.
- the refrigerant pressure in the gas-liquid separator (15) is surely set to a critical pressure.
- the volume ratio can be more efficiently compressed in two stages.
- a third invention is characterized in that, in the second invention, the volume ratio is 1.0.
- the volume ratio of the low-stage compression mechanism (34) and the volume ratio of the high-stage compression mechanism (35) are set to the same volume ratio.
- a fourth invention is the invention according to any one of the first to third inventions, wherein the low-stage compression mechanism (34) and the high-stage compression mechanism (35) are constituted by a rotary compression mechanism. It is characterized by this.
- the low-stage compression mechanism (34) and the high-stage compression mechanism (35), which are rotary compression mechanisms, are connected to each other by the drive shaft (33), so that the compressor (30) is Composed.
- the volume ratio of the low-stage compression mechanism (34) and the high-stage compression mechanism (35) is set in a range larger than 0.8 and smaller than 1.3.
- the volume ratio is larger than 0.8, the pressure of the refrigerant in the gas-liquid separator (15) can be made smaller than the critical pressure. Therefore, according to the present invention, the desired intermediate pressure gas injection can be performed in the refrigerant circuit (10), and the COP of the refrigeration apparatus can be improved.
- this volume ratio is made smaller than 1.3, the refrigerant that does not cause a reduction in compression efficiency due to a shortage of the amount of refrigerant sucked by the high-stage compression mechanism (35) can be compressed in two stages. Therefore, according to the present invention, the COP of the refrigeration apparatus can be further improved.
- the volume ratio of the low-stage compression mechanism (34) and the high-stage compression mechanism (35) is set to 0. . 9 or more 1.
- the range is 1 or less. That is, in the present invention, the volume ratio of the low-stage compression mechanism (34) and the high-stage compression mechanism (35) is set in a more optimal range. Therefore, according to the present invention, the COP of the refrigeration apparatus can be further improved.
- the volume ratio of the low-stage compression mechanism (34) and the volume ratio of the high-stage compression mechanism (35) are set to the same volume ratio. For this reason, according to the present invention, the low-stage compression mechanism (
- the compressor (30) and the high-stage compression mechanism (35) can have the same compression mechanism specifications, and the compressor (30) can be reduced in cost and simplified.
- the desired intermediate pressure gas injection can be performed to improve the COP. I'll do it.
