Detailed Description
(embodiment mode 1)
The present embodiment will be described below with reference to the drawings. First, an air conditioner according to embodiment 1 will be described with reference to fig. 1 to 2. Reference numeral 1 in fig. 1 denotes an air conditioner. The air conditioner 1 includes an outdoor unit 2 installed outdoors and an indoor unit 3 installed indoors.
The outdoor unit 2 and the indoor unit 3 are connected by a liquid-side pipe 4 for mainly guiding a liquid refrigerant and a gas-side pipe 5 for mainly guiding a gas refrigerant. A refrigeration cycle is configured by circulating a refrigerant between the outdoor unit 2 and the indoor unit 3.
The indoor unit 3 includes: an indoor heat exchanger 6 that exchanges heat between the refrigerant and the indoor air, an indoor fan 7 that blows air from the indoor heat exchanger 6 and blows the air to the room to be air-conditioned, and an electric expansion valve 8 that expands the refrigerant. A liquid-side pipe 4 is connected to one end of the indoor heat exchanger 6 via an electric expansion valve 8, and a gas-side pipe 5 is connected to the other end of the indoor heat exchanger 6.
The outdoor unit 2 includes an outdoor heat exchanger 9 that performs heat exchange between refrigerant and outdoor air, an outdoor fan 10 that sends air to the outdoor heat exchanger 9, a four-way valve 11 that switches the flow direction of the refrigerant between a cooling operation and a heating operation, a reservoir 12 that accumulates liquid refrigerant, a compressor 13 that compresses gaseous refrigerant, and a receiver 14 that is provided on the refrigerant suction side of the compressor 13.
The outdoor unit 2 includes a 1 st refrigerant pipe 15 that connects the outdoor heat exchanger 9 and the four-way valve 11, a 2 nd refrigerant pipe 16 that connects the four-way valve 11 and the reservoir 12, and a 3 rd refrigerant pipe 17 that connects the compressor 13 and the four-way valve 11. The liquid-side pipe 4 is connected to one end of the outdoor heat exchanger 9, and the 1 st refrigerant pipe 15 is connected to the other end of the outdoor heat exchanger 9.
The outdoor unit 2 includes an intake pipe 18 for guiding the gaseous refrigerant from the upper portion of the reservoir 12 to the compressor 13, an oil return pipe 19 for guiding the refrigerating machine oil used for lubricating the compressor 13 from the bottom portion of the reservoir 12 to the intake pipe 18, an electromagnetic valve 20 provided in the oil return pipe 19, and a connection pipe 21 for connecting the reservoir 14 and the compressor 13.
In fig. 1, solid arrows indicate the flow of refrigerant in the outdoor unit 2 during the cooling operation and the heating operation. The dotted arrows indicate the flow of the refrigerant during the cooling operation. The arrows of the chain line indicate the flow of the refrigerant during the heating operation. The four-way valve 11 is used to switch the flow of refrigerant corresponding to the operating state.
The refrigerant flowing from the four-way valve 11 to the compressor 13 through the accumulator 12 always flows in the same direction regardless of the operation state. For example, the refrigerant having passed through the four-way valve 11 is guided to the reservoir 12 by the 2 nd refrigerant pipe 16. The refrigerant after passing through the reservoir 12 is guided to the receiver tank 14 by the suction pipe 18. The refrigerant having passed through the receiver tank 14 is guided to the compressor 13 by the connection pipe 21. The refrigerant having passed through the compressor 13 is guided to the four-way valve 11 by the 3 rd refrigerant pipe 17.
During the cooling operation, the refrigerant is discharged from the compressor 13 of the outdoor unit 2 in a high-temperature high-pressure gas state and flows into the outdoor heat exchanger 9. The refrigerant exchanges heat with outdoor air in the outdoor heat exchanger 9, condenses, turns into a liquid state, and flows into the liquid-side pipe 4 a. In the indoor unit 3, the liquid refrigerant flows from the liquid-side pipe 4 into the indoor heat exchanger 6 via the motor-operated expansion valve 8. The liquid refrigerant is evaporated and gasified by heat exchange with air in the room to be air-conditioned in the indoor heat exchanger 6.
Further, the gas-like refrigerant discharged from the indoor heat exchanger 6 of the indoor unit 3 flows into the gas-side pipe 5. The low-temperature low-pressure gas refrigerant is compressed by the compressor 13 of the outdoor unit 2 to become a high-temperature high-pressure gas, and is discharged from the compressor 13 again.
During the heating operation, the refrigerant is discharged from the compressor 13 of the outdoor unit 2 in a high-temperature high-pressure gas state and flows into the gas-side pipe 5. In the indoor unit 3, the gaseous refrigerant flows into the indoor heat exchanger 6. The gaseous refrigerant is condensed and liquefied by heat exchange with air in the room to be air-conditioned in the indoor heat exchanger 6.
The liquid refrigerant discharged from the indoor heat exchanger 6 of the indoor unit 3 flows into the liquid-side pipe 4 via the motor-operated expansion valve 8. In the outdoor unit 2, the liquid refrigerant flows into the outdoor heat exchanger 9 from the liquid-side pipe 4. The liquid refrigerant is evaporated and gasified by heat exchange with outdoor air in the outdoor heat exchanger 9. The low-temperature low-pressure gas refrigerant is compressed by the compressor 13 to become a high-temperature high-pressure gas, and is discharged from the compressor 13 again.
The liquid-like refrigerant is accumulated in the accumulator 12. For example, in the indoor heat exchanger 6 or the outdoor heat exchanger 9 functioning as an evaporator, the liquid refrigerant may not be completely evaporated. In this case, a refrigerant in a mixed state of a gaseous refrigerant and a liquid refrigerant may circulate. If a large amount of liquid refrigerant is sucked into the compressor 13, the compressor 13 may malfunction. Therefore, before the refrigerant is sucked into the compressor 13, the gas refrigerant and the liquid refrigerant are separated by the accumulator 12, and the liquid refrigerant is accumulated.
As shown in fig. 2, the reservoir 12 is a cylindrical box body having a central axis extending in the vertical direction. The reservoir 12 is installed in a state of being erected from the reference surface 23 using the leg portion 22. A 2 nd refrigerant pipe 16 and a suction pipe 18 are connected to an upper portion of the reservoir 12. When the refrigerant flows into the internal space of the reservoir 12 through the 2 nd refrigerant pipe 16, the gaseous refrigerant flows out through the suction pipe 18. On the other hand, the liquid-like refrigerant freely falls due to gravity, and is thus collected in the lower portion of the reservoir 12.
A prescribed amount of liquid-like refrigerant is accumulated in the accumulator 12. In designing the reservoir 12, the liquid level H1 for the maximum amount of reservoir is set. This maximum storage amount is provided with a margin, so that the liquid-like refrigerant is less likely to be stored to the liquid level H1 of the maximum storage amount of the reservoir 12 in operation.
The compressor 13 includes a compression unit 24 that compresses a gaseous refrigerant, a motor 25 that operates the compression unit 24, and a compressor housing 26 that houses the compression unit 24 and the motor 25. The compressor housing 26 is a cylindrical container having a central axis extending in the vertical direction. The compressor housing 26 is provided in a state of standing from the reference surface 23 by using the leg portions 27.
Embodiment 1 shows a rotary compressor 13 as an example. In the internal space of the compressor housing 26, a compression section 24 is provided at the lower portion, and a motor 25 is provided at the upper portion. The compression unit 24 and the motor 25 are coupled by a drive shaft 28. The refrigerant in a gas state is compressed in the compression portion 24 by the driving force of the motor 25, is in a high-temperature high-pressure gas state, and is discharged from the 3 rd refrigerant pipe 17 connected to the discharge port of the compressor housing 26.
On the side of the compressor housing 26, the receiver tank 14 is mounted. In embodiment 1, the reservoir 14 is disposed outside of the compressor housing 26. The liquid storage tank 14 is a cylindrical tank body having a central axis extending in the vertical direction. A suction pipe 18 is connected to an upper portion of the reservoir tank 14.
Inside the receiver tank 14, a connection pipe 21 extending in the vertical direction along the central axis is disposed. The connection pipe 21 passes through the bottom of the receiver tank 14, is led out to the outside, and is connected to the lower side of the side portion of the compressor housing 26. That is, the suction port of the compressor 13 is connected to the suction pipe 18 through the accumulator tank 14.
A lid 29 is provided above the connection pipe 21 disposed inside the receiver tank 14, and prevents the liquid refrigerant flowing from the suction pipe 18 from flowing into the connection pipe 21 at a burst. The liquid-like refrigerant flowing from the suction pipe 18 is accumulated inside the receiver tank 14. That is, the reservoir 14 has a reservoir portion 30. The reservoir 30 is a space within the reservoir 14. In embodiment 1, the volume from the bottom of the liquid reservoir tank 14 to the upper end height H2 of the connection pipe 21 is defined as the liquid reservoir 30. The liquid reservoir 30 is provided upstream of the compression portion 24 in the flow of the refrigerant.
The gaseous refrigerant flowing from the suction pipe 18 into the receiver 14 flows into the inside of the connection pipe 21 from between the upper end of the connection pipe 21 and the cap 29, and is sucked into the compressor 13.
A small hole 31 is formed in the lower portion of the connection pipe 21 in the receiver tank 14. The liquid refrigerant collected in the receiver tank 14 gradually flows into the connection pipe 21 through the small hole 31, and is sucked into the compressor 13. Even if a small amount of liquid refrigerant gradually flows into the compressor 13, no malfunction is caused.
Inside the compressor housing 26, refrigerating machine oil for lubrication of the compression portion 24 or the motor 25 is accumulated. A part of the refrigerating machine oil circulates in the refrigeration cycle together with the refrigerant. If the liquid-like refrigerant is accumulated in the reservoir 12, the refrigerator oil is accumulated at the bottom thereof. Therefore, when the compressor 13 is operated, the electromagnetic valve 20 provided in the oil return pipe 19 is opened, and the refrigerating machine oil is guided from the bottom of the reservoir 12 to the suction pipe 18 and returned to the compressor 13.
The oil return pipe 19 has an inner diameter smaller than that of the suction pipe 18. The liquid refrigerant collected in the receiver 12 may flow to the compressor 13 through the oil return pipe 19, but the operation of the compressor 13 is not affected by the degree of the flow rate.
Sometimes, a failure occurs in a state where the solenoid valve 20 is open, that is, a so-called Open (ON) failure occurs. The solenoid valve 20 is opened when the compressor 13 is operated, and thus no problem occurs in a state where the solenoid valve 20 is opened during operation. On the other hand, when the electromagnetic valve 20 is opened while the compressor 13 is stopped, that is, while the air conditioner 1 is stopped, the liquid refrigerant collected in the receiver 12 flows into the suction pipe 18 through the oil return pipe 19. Then, the liquid-like refrigerant is accumulated in the suction pipe 18.
In embodiment 1, when the air conditioning apparatus 1 is started up with the liquid refrigerant stored in the suction pipe 18, the liquid refrigerant is temporarily stored in the liquid storage portion 30 of the liquid storage tank 14. Therefore, the liquid refrigerant collected in the suction pipe 18 does not flow into the compressor 13 at a time. Thus, even if the electromagnetic valve 20 of the oil return pipe 19 fails, the compressor 24 can be prevented from failing when the liquid refrigerant is stored in the suction pipe 18.
The suction pipe 18 extending from the upper portion of the reservoir 12 is bent in a U shape and extends downward after extending upward. The suction tube 18 extends below the liquid level H1 of the maximum reservoir volume of the reservoir 12. Then, the suction pipe 18 extends in the horizontal direction along the reference surface 23 and extends upward again in the vicinity of the compressor 13. The suction pipe 18 extends to a position above a liquid level H1 of the maximum amount of the reservoir 12, and then bends in a U shape to extend downward. The suction line 18 is then connected to the reservoir 14.
The suction pipe 18 has a portion disposed above the liquid level H1 of the maximum collection amount of the reservoir 12. With this portion, even if the liquid refrigerant is collected to the liquid level H1 of the maximum collection amount, the refrigerant does not flow into the compressor 13.
On the other hand, in the suction pipe 18, there is a possibility that the liquid refrigerant accumulates in a portion disposed below the liquid level H1 of the maximum accumulation amount of the accumulator 12. The reservoir portion 30 of the reservoir tank 14 has a specific volume greater than the maximum volume of the liquid-like refrigerant pooled in the suction pipe 18. The specific volume is set to be larger than the volume of the portion of the suction pipe 18 (the halftone dot portion in fig. 2) below the liquid level H1 of the maximum reservoir amount of the reservoir 12.
The specific volume of the reservoir 30 may be set to a partial volume containing the suction pipe 18 and the volume of the oil return pipe 19.
Thus, the specific volume of the receiver 30 is larger than the maximum amount of the liquid refrigerant that is collected in the suction pipe 18, and therefore the liquid refrigerant can be collected in the receiver 30. Therefore, the liquid refrigerant can be prevented from flowing into the compression portion 24 at the time of starting the air conditioner 1.
In embodiment 1, since the reservoir tank 14 having the reservoir portion 30 is provided outside the compressor housing 26, the volume of the reservoir portion 30 can be set appropriately regardless of the size of the compressor housing 26 of the compressor 13.
(embodiment mode 2)
Next, an air conditioner 1A according to embodiment 2 will be described with reference to fig. 3 to 4. Note that the same components as those described in the above embodiments are denoted by the same reference numerals, and redundant description thereof is omitted.
As shown in fig. 3, in embodiment 2, the liquid reservoir tank 14 of embodiment 1 described above is not provided. In embodiment 2, the suction pipe 18 is directly connected to the lower side of the side portion of the compressor housing 26A.
As shown in fig. 4, the compressor 13A according to embodiment 2 includes: a compression unit 24A for compressing a gaseous refrigerant, a motor 25A for operating the compression unit 24A, and a compressor housing 26A for housing the compression unit 24A and the motor 25A.
The compressor housing 26A has a liquid reservoir 30A. The liquid reservoir 30A is a space inside the compressor housing 26A. In embodiment 2, the volume from the bottom of the compressor 13A to a predetermined height H3 is defined as the liquid reservoir 30A. This height H3 is set to be lower than suction port 32 of compressing unit 24A. The liquid reservoir 30A is provided upstream of the compression portion 24A in the flow of the refrigerant.
The liquid reservoir 30A of the compressor housing 26A has a specific volume larger than the maximum volume of the liquid refrigerant pooled in the suction pipe 18. The specific volume is set to be larger than the volume of the portion of the suction pipe 18 (the halftone dot portion in fig. 4) below the liquid level H1 of the maximum reservoir amount of the reservoir 12.
The specific volume of the reservoir 30A may be set to a partial volume containing the suction pipe 18 and the volume of the oil return pipe 19.
In embodiment 2, when the air conditioning apparatus 1A is started up with the liquid refrigerant accumulated in the suction pipe 18, the liquid refrigerant is temporarily accumulated in the liquid reservoir 30A of the compressor housing 26A. Therefore, the liquid refrigerant collected in the suction pipe 18 does not flow into the compression portion 24A at a time. Thus, even if the electromagnetic valve 20 of the oil return pipe 19 fails, when the liquid refrigerant is stored in the suction pipe 18, the compressor 24A can be prevented from failing.
In embodiment 2, since the compressor housing 26A has the liquid reservoir 30A, the compact compressor 13A in which the liquid reservoir 30A is incorporated in the compressor housing 26A can be formed.
The air conditioner according to the present embodiment has been described based on embodiments 1 and 2, but the configuration applied to any one embodiment may be applied to other embodiments, and the configurations applied to the respective embodiments may be combined.
According to at least 1 embodiment described above, by providing the liquid reservoir portion which is provided on the upstream side of the compression portion and has a specific volume larger than the maximum volume of the liquid refrigerant pooled in the suction pipe, even if the electromagnetic valve of the oil return pipe fails, when the liquid refrigerant is pooled in the suction pipe, the compressor can be prevented from failing.
Several embodiments of the present invention have been described, but these embodiments are presented by way of example only and are not intended to limit the scope of the invention. The embodiments may be implemented in various forms, and various omissions, substitutions, changes, and combinations may be made without departing from the spirit of the invention.
