Embodiment 1.
FIG. 1 is a perspective view showing a refrigerant recovery cylinder to which a refrigerant recovery cylinder cooling device according to Embodiment 1 is attached. A refrigerant recovery cylinder cooling device 1 according to Embodiment 1 is a device for cooling a refrigerant recovery cylinder 2 .

The refrigerant recovery cylinder 2 is a container for recovering refrigerant flowing through a refrigerant circuit included in an air conditioner or a refrigeration system. The refrigerant recovery cylinder 2 is connected to the refrigerant circuit via a refrigerant recovery pipe 201 . Refrigerant recovered from the refrigerant circuit is put into the refrigerant recovery cylinder 2 through a pipe 201 . The refrigerant put into the refrigerant recovery cylinder 2 is a high-pressure gas. The maximum weight of refrigerant that can be put into the refrigerant recovery cylinder 2 is, for example, 10 kg or 20 kg.

Examples of the refrigerant recovered in the refrigerant recovery cylinder 2 include R410.

When the temperature around the refrigerant recovery cylinder 2 is high, the pressure of the refrigerant in the refrigerant recovery cylinder 2 increases. When the pressure of the refrigerant contained in the refrigerant recovery cylinder 2 is high, it becomes difficult for the refrigerant to enter the refrigerant recovery cylinder 2 . Since it becomes difficult for the refrigerant to enter the refrigerant recovery cylinder 2 , a sufficient amount of refrigerant cannot be introduced into the refrigerant recovery cylinder 2 . As a result, when the temperature around the refrigerant recovery cylinder 2 is high, the efficiency of recovering the refrigerant in the refrigerant recovery cylinder 2 is lowered. Therefore, when the temperature around the refrigerant recovery cylinder 2 is high, it is necessary to cool the refrigerant recovery cylinder 2 .

The refrigerant recovery cylinder 2 has a cylindrical shape. Therefore, the shape of the side surface 202 of the refrigerant recovery cylinder 2 is circular when viewed from above. The refrigerant recovery cylinder 2 is made of iron. Therefore, the refrigerant recovery cylinder 2 is magnetized by the magnet.

A refrigerant recovery cylinder cooling device 1 according to Embodiment 1 includes a long member 101 , a coolant supply member 102 , and a coolant recovery member 103 .

A channel 105 through which a coolant 104 flows is formed in the elongated member 101 . The channel 105 is formed extending in the longitudinal direction of the long member 101 . The long member 101 is bendable and deformable. Therefore, the long member 101 can be wound around the side surface 202 of the refrigerant recovery cylinder 2 . The longitudinal dimension of the elongated member 101 is several times larger than the outer peripheral dimension of the side surface 202 of the refrigerant recovery cylinder 2 . Therefore, the long member 101 can be spirally wound around the side surface 202 of the refrigerant recovery cylinder 2 .

An opening 106 connected to the flow path 105 is formed on the side surface of the long member 101 . The opening 106 is formed extending in the longitudinal direction of the long member 101 . When the long member 101 is attached to the side surface 202 of the refrigerant recovery cylinder 2, the long member 101 is arranged so that the opening 106 faces upward.

The long member 101 is made of iron, copper or aluminum, for example. Note that the material forming the long member 101 is not limited to iron, copper, or aluminum, and any material having high thermal conductivity may be used.

The coolant 104 is composed of water, for example. The material constituting the cooling liquid 104 is not limited to water, and any liquid that can cool the refrigerant recovery cylinder 2 by flowing through the flow path 105 may be used.

The cooling liquid supply member 102 has a cylindrical shape. The shape of the coolant supply member 102 is such that it can be carried by an operator. The coolant supply member 102 is made of, for example, a PET bottle. A cooling liquid 104 is stored in advance in the cooling liquid supply member 102 . As a result, even if the refrigerant recovery work is performed in a place such as the roof of a building where there is no faucet, the coolant 104 necessary for the refrigerant recovery work can be secured in advance.

The coolant supply member 102 is carried by an operator. A worker holds the cooling liquid supply member 102 and tilts the cooling liquid supply member 102 with respect to the vertical line, whereby the cooling liquid 104 flows out from the inside to the outside of the cooling liquid supply member 102 . The cooling liquid 104 coming out from the inside of the cooling liquid supply member 102 enters the channel 105 of the long member 101 .

The cooling liquid recovery member 103 is composed of a container in which the cooling liquid 104 is stored. The coolant 104 that has passed through the flow path 105 is stored in the coolant recovery member 103 . As a result, even when the refrigerant recovery work is performed in a place such as the roof of a building where there is no drainage facility, the cooling liquid 104 used in the refrigerant recovery work can be recovered and the recovered cooling liquid 104 can be drained. You can carry it to your facility.

The refrigerant recovery cylinder cooling device 1 further includes a mounting member 107 . The mounting member 107 is provided on the elongated member 101 . Also, the mounting member 107 is attached to the side surface of the long member 101 . As a method for fixing the mounting member 107 to the elongated member 101, for example, a method using an adhesive can be used.

The mounting member 107 is composed of a permanent magnet. Therefore, the mounting member 107 is detachably attached to the side surface 202 of the refrigerant recovery cylinder 2 using magnetic force. The shape of the mounting member 107 is a sheet shape. The attachment member 107 can be bent and deformed in the same manner as the long member 101 . Therefore, the mounting member 107 can be spirally wound around the side surface 202 of the refrigerant recovery cylinder 2 together with the elongated member 101 .

Next, a procedure for cooling the refrigerant recovery cylinder 2 using the refrigerant recovery cylinder cooling device 1 will be described. First, an operator spirally winds the long member 101 around the side surface 202 of the refrigerant recovery cylinder 2 , and with the long member 101 spirally wound around the side surface 202 of the refrigerant recovery cylinder 2 , the mounting member 107 is removed. The elongated member 101 is attached to the side surface 202 of the refrigerant recovery cylinder 2 through the hole. When the long member 101 is spirally wound around the side surface 202 of the refrigerant recovery cylinder 2 , the operator must ensure that the long member 101 is wound over the entire height direction of the side surface 202 of the refrigerant recovery cylinder 2 . Then, the position of the long member 101 is adjusted.

When spirally winding the long member 101 around the side surface 202 of the refrigerant recovery cylinder 2, the operator places one longitudinal end of the long member 101 above the side surface 202 of the refrigerant recovery cylinder 2, and The other longitudinal end of the member 101 is placed under the side surface 202 of the refrigerant recovery cylinder 2 . Further, when the long member 101 is spirally wound around the side surface 202 of the refrigerant recovery cylinder 2, the worker winds the long member 101 from one end in the longitudinal direction of the long member 101 toward the other end in the longitudinal direction of the long member 101. The long member 101 is arranged so that the position in the height direction faces downward.

After that, the operator arranges the coolant recovery member 103 below the portion of the flow path 105 arranged at the other longitudinal end of the long member 101 . When the cooling liquid recovery member 103 is arranged, the operator positions the cooling liquid recovery member 103 so that the cooling liquid 104 that has passed through the flow path 105 of the long member 101 enters the cooling liquid recovery member 103. adjust.

After that, the operator uses the cooling liquid supply member 102 to fill the portion of the flow path 105 arranged at one longitudinal end of the long member 101 with the cooling liquid 104 . The cooling liquid 104 put into the channel 105 flows through the channel 105 . The coolant 104 that has passed through the flow path 105 enters the coolant recovery member 103 .

As the coolant 104 flows through the channel 105 , the elongated member 101 is cooled as a whole. By cooling the long member 101 , the side surface 202 of the refrigerant recovery cylinder 2 is cooled via the mounting member 107 .

The long member 101 is wound over the entire height direction of the side surface 202 of the refrigerant recovery cylinder 2 . Therefore, the entire height direction of the side surface 202 of the refrigerant recovery cylinder 2 is cooled.

By cooling the side surface 202 of the refrigerant recovery cylinder 2, the refrigerant contained in the refrigerant recovery cylinder 2 is cooled. As the refrigerant contained in the refrigerant recovery cylinder 2 is cooled, the pressure of the refrigerant contained in the refrigerant recovery cylinder 2 decreases. As a result, a sufficient amount of refrigerant recovered from the refrigerant circuit enters the refrigerant recovery cylinder 2 . When a sufficient amount of refrigerant recovered from the refrigerant circuit enters the refrigerant recovery cylinder 2, the cooling of the refrigerant recovery cylinder 2 using the cooling device 1 for the refrigerant recovery cylinder is completed.

The channel 105 is formed extending in the longitudinal direction of the long member 101 . The elongated member 101 is attached to the refrigerant recovery cylinder 2 via the attachment member 107 while being spirally wound around the side surface 202 of the refrigerant recovery cylinder 2 . With this configuration, it is possible to easily attach and detach the long member 101 to and from the side surface 202 of the refrigerant recovery cylinder 2 . As a result, the working efficiency of cooling the refrigerant recovery cylinder 2 can be improved.

Further, the elongated member 101 is bendable and deformable. Thereby, the shape of the long member 101 can be changed according to the shape of the side surface 202 of the refrigerant recovery cylinder 2 . Therefore, the long member 101 can be helically wound around the side surfaces 202 of a plurality of types of refrigerant recovery cylinders 2 having side surfaces 202 with different shapes. As a result, the refrigerant recovery cylinder cooling device 1 can be used for a plurality of types of refrigerant recovery cylinders 2 .

An opening 106 connected to the flow path 105 is formed on the side surface of the long member 101 . The opening 106 is formed extending in the longitudinal direction of the long member 101 . According to this configuration, the coolant 104 can be easily introduced into the channel 105 from the opening 106 . As a result, the operation of introducing the coolant 104 into the flow path 105 can be easily performed.

Further, the long member 101 is disposed so that the opening 106 faces upward when the long member 101 is spirally wound around the side surface 202 of the refrigerant recovery cylinder 2 .

By cooling the long member 101 , the refrigerant recovery cylinder 2 is cooled via the mounting member 107 .

Further, the long member 101 is cooled by air flowing around the long member 101 spirally wound around the side surface 202 of the refrigerant recovery cylinder 2 . By cooling the long member 101 , the refrigerant recovery cylinder 2 is cooled via the mounting member 107 .

Air that enters from the outside of the housing 108 to the inside of the housing 108 through the through hole 111 passes near the cooling liquid 104 stored in the cooling liquid recovery member 103 . The air entering from the outside of the housing 108 to the inside of the housing 108 through the through holes 111 passes near the coolant 104, thereby cooling the air entering from the outside of the housing 108 to the inside of the housing 108 through the through holes 111. be.

FIG. 5 is a cross-sectional view showing the long member 101 and the mounting member 107 wound around the side surface 202 of the refrigerant recovery cylinder 2 of FIG. The elongated member 101 has an elongated member main body 117 and fin portions 118 provided on the elongated member main body 117 .

A channel 105 is formed in the elongated member main body 117 . A mounting member 107 is provided on one side surface of the long member body 117 in the width direction. Therefore, one widthwise side surface of the long member main body 117 is attached to the side surface 202 of the refrigerant recovery cylinder 2 via the attachment member 107 .

The fin portion 118 is provided on the other side surface in the width direction of the long member main body 117 . A plurality of grooves 119 are formed in the fin portion 118 . Each groove 119 is formed to extend in the longitudinal direction of the long member 101 . Each groove 119 may be formed so as to extend vertically when the long member 101 is wound around the side surface 202 of the refrigerant recovery cylinder 2 .

Air passing through the housing 108 passes around the fin portion 118 . Fin portion 118 is cooled by air passing through housing 108 and passing around fin portion 118 . Since the elongated member 101 has the fin portion 118, the surface area of the elongated member 101 is increased. Therefore, the air passing through the housing 108 cools the elongate member 101 more effectively. By cooling the long member 101 more effectively, the side surface 202 of the refrigerant recovery cylinder 2 is cooled more effectively via the mounting member 107 . Other configurations are the same as those of the first embodiment.

Next, a procedure for cooling the refrigerant recovery cylinder 2 using the refrigerant recovery cylinder cooling device 1 will be described. First, an operator spirally winds the long member 101 around the side surface 202 of the refrigerant recovery cylinder 2 , and with the long member 101 spirally wound around the side surface 202 of the refrigerant recovery cylinder 2 , the mounting member 107 is removed. The elongated member 101 is attached to the side surface 202 of the refrigerant recovery cylinder 2 through the hole. When the long member 101 is spirally wound around the side surface 202 of the refrigerant recovery cylinder 2 , the operator must ensure that the long member 101 is wound over the entire height direction of the side surface 202 of the refrigerant recovery cylinder 2 . Then, the position of the long member 101 is adjusted.

When spirally winding the long member 101 around the side surface 202 of the refrigerant recovery cylinder 2, the operator places one longitudinal end of the long member 101 above the side surface 202 of the refrigerant recovery cylinder 2, and The other longitudinal end of the member 101 is placed under the side surface 202 of the refrigerant recovery cylinder 2 . Further, when the long member 101 is spirally wound around the side surface 202 of the refrigerant recovery cylinder 2, the worker winds the long member 101 from one end in the longitudinal direction of the long member 101 toward the other end in the longitudinal direction of the long member 101. The long member 101 is arranged so that the position in the height direction faces downward.

After that, the operator arranges the coolant recovery member 103 below the portion of the flow path 105 arranged at the other longitudinal end of the long member 101 . When the cooling liquid recovery member 103 is arranged, the operator positions the cooling liquid recovery member 103 so that the cooling liquid 104 that has passed through the flow path 105 of the long member 101 enters the cooling liquid recovery member 103. adjust.

After that, the operator attaches the housing 108 to the refrigerant recovery cylinder 2 so that the refrigerant recovery cylinder 2 is arranged inside the housing 108 .

After that, the operator uses the cooling liquid supply member 102 to put the cooling liquid 104 into the cooling liquid recovery member 103 . The cooling liquid 104 contained in the cooling liquid recovery member 103 enters the portion of the flow path 105 arranged at one longitudinal end of the long member 101 by the cooling liquid circulation device 113 . The cooling liquid 104 put into the channel 105 flows through the channel 105 . The coolant 104 that has passed through the flow path 105 enters the coolant recovery member 103 . In addition to the cooling liquid 104, the cooling liquid recovery member 103 may contain, for example, ice. By putting ice in the cooling liquid recovery member 103, the temperature of the cooling liquid 104 contained in the cooling liquid recovery member 103 can be lowered.

As the coolant 104 flows through the channel 105 , the elongated member 101 is cooled as a whole. By cooling the long member 101 , the side surface 202 of the refrigerant recovery cylinder 2 is cooled via the mounting member 107 .

A fan 109 creates a flow of air through the housing 108 . Elongated member 101 is cooled more effectively by creating a flow of air through housing 108 .

The long member 101 is wound over the entire height direction of the side surface 202 of the refrigerant recovery cylinder 2 . Therefore, the entire height direction of the side surface 202 of the refrigerant recovery cylinder 2 is cooled.

By cooling the side surface 202 of the refrigerant recovery cylinder 2, the refrigerant contained in the refrigerant recovery cylinder 2 is cooled. As the refrigerant contained in the refrigerant recovery cylinder 2 is cooled, the pressure of the refrigerant contained in the refrigerant recovery cylinder 2 decreases. As a result, a sufficient amount of refrigerant recovered from the refrigerant circuit enters the refrigerant recovery cylinder 2 . When a sufficient amount of refrigerant recovered from the refrigerant circuit enters the refrigerant recovery cylinder 2, the cooling of the refrigerant recovery cylinder 2 using the cooling device 1 for the refrigerant recovery cylinder is completed.

As described above, the refrigerant recovery cylinder cooling device 1 according to Embodiment 2 further includes the coolant recovery member 103 and the coolant circulation device 113 . The coolant 104 that has passed through the flow path 105 is stored in the coolant recovery member 103 . The coolant circulation device 113 assembles the coolant 104 stored in the coolant recovery member 103 and supplies the assembled coolant 104 to the flow path 105 . According to this configuration, the cooling liquid 104 that passes through the flow path 105 and is collected in the cooling liquid recovery member 103 is reused and supplied to the flow path 105 . As a result, the refrigerant recovery cylinder 2 can be cooled more effectively using a constant amount of the coolant 104 .

The refrigerant recovery cylinder cooling device 1 according to the second embodiment further includes a housing 108 and a fan 109 . Inside the housing 108 , the refrigerant recovery cylinder 2 is accommodated with the long member 101 spirally wound around the side surface 202 of the refrigerant recovery cylinder 2 . Fan 109 generates airflow through housing 108 . According to this configuration, vaporization of the cooling liquid 104 flowing through the flow path 105 can be promoted. Thereby, the long member 101 can be cooled more effectively. Also, by creating an air flow through the housing 108 , the air flows around the elongate member 101 . By flowing air around the elongate member 101, the elongate member 101 can be cooled more effectively.

The long member 101 also has a long member main body 117 and a fin portion 118 provided on the long member main body 117 and having a groove 119 formed therein. Air passing through the housing 108 passes around the fin portion 118 . According to this configuration, the fin portion 118 is cooled by air passing through the housing 108 and passing around the fin portion 118 .
