Description
The present invention relates to a connecting
apparatus for installing an air conditioner used for
connecting an indoor unit and an outdoor unit using
connecting pipes.
A refrigeration cycle used for an air conditioner
comprises a mechanical portion in which a compressor, a
heat exchanger and a refrigerant flow rate controller
having an expanding mechanism such as a capillary tube or
an expanding valve, are connected by pipes such as copper
pipes, and fluid charged in the refrigeration cycle such
as refrigerant and lubricant oil composition.
A separate-type air conditioner comprises an outdoor
unit having a compressor and a heat exchanger, and an indoor
unit having another heat exchanger installed at a place
where refrigeration air conditioning is performed. The
outdoor unit and the indoor unit are connected through
connection pipes such as copper pipes. In this type of
refrigeration cycle, it is common to establish a the
refrigeration cycle in the following way: first, a part
or all of the refrigerant and lubricant oil composition
is previously charged into the outdoor unit and the valves
of the outdoor unit are closed; and then the outdoor unit
is connected to the indoor unit by the connection pipes
at the time of installing.
However, if the pipes are merely connected in this
way, air remains in the indoor unit and the connection pipes.
In order to remove the air, a conventional method employs
a vacuum pump connected to a refrigerant charge port
provided at the valve of the outdoor unit. And, after the
air is removed by the vacuum pump, the valve is opened to
connect the indoor unit and the outdoor unit, thereby
forming the refrigeration cycle.
There is another simple installing method in which
a valve of the outdoor unit is opened at the time of the
installing so that the refrigerant in the outdoor unit is
allowed to flow into the one of connection pipes, the indoor
unit and then the other connection pipe and is released
together with the air remained in the system from a gap
created by moderating the connection of a connection port
or a refrigerant charge port provided at the other valve
of the outdoor unit; thereby replacing the gas in the indoor
unit and the connection pipes.
In view of these conventional methods, Japanese
Patent Application Laid-open No.H3-70953 discloses a
method to establish a refrigeration cycle without using
a vacuum pump in which, after replacing the gas in the
refrigeration cycle by oxygen, the refrigerant is charged
and the oxygen is solidified by oxygen fixing agent disposed
in the refrigeration cycle.
Further, Japanese Patent Application Laid-open
No.H7-159004 discloses a method for charging, into a
portion of a refrigeration cycle, material capable of
absorbing two or more of water, oxygen, nitrogen, carbon
dioxide and the like in the air in such a separate type
air conditioner in which among a freezing compressor, a
condenser, an expanding mechanism such as a capillary tube
and an expanding valve, and an evaporator, one of the
condenser and the evaporator, or one of the condenser and
the evaporator is separated from the expanding mechanism
and connected by the pipes.
Further, Japanese Patent Application Laid-open
No.H7-269994 discloses a refrigeration cycle in which
oxygen absorbing agent is disposed in a refrigerant
circulating system.
Further, Japanese Patent Application Laid-open
No.H9-292168 discloses a method in which air absorbing
agent is disposed for removing air in a pipe and an indoor
unit, and a method in which after carbon dioxide is charged
in the pipe and the indoor unit, the carbon dioxide in the
pipe and the indoor unit is absorbed by carbon dioxide
absorbing agent to establish vacuum.
Since air remaining in the refrigeration cycle
deteriorates freezing ability as non-condensation gas, and
oxygen and water facilitate degradation of freezer oil,
iron and the like in the refrigeration cycle, it is
inevitably necessary to remove the air.
Among the above-described conventional techniques,
the method for removing the air using the vacuum pump is
common. However, in order to operate the vacuum pump in
the installing site, it is necessary that an electric power
supply is available; further, it is difficult to use the
pump on a roof and the like, and therefore, this method
cannot be called a simple method.
Further, in the case of the replacing method of air
using refrigerant, it is not possible to avoid emissions
of chlorofluorocarbon, which is the refrigerant, into the
atmosphere, and this is not preferable because of
global-warming problem in view of global environment
concerns.

replacing gas after the air in the indoor heat exchanger
and the connection pipes is once replaced by the replacing
gas, no simple apparatus for collecting the replacing gas
has not been proposed.

example, when R410A is used as the refrigerant, the global
warming coefficient (GWP) is 1730, it is preferable that
the replacing gas has a global warming coefficient smaller
than this value and the replacing gas is inert toward the
refrigeration cycle. Examples of the replacing gas are
carbon dioxide (GWP=1), propane (GWP<3), butane (GWP<3)
and the like.
On the other hand, a material which absorbs the
replacing gas is charged in the replacing gas collecting
container 40. More specifically, when carbon dioxide is
charged as the replacing gas, zeolite, epoxy compound,
calcium hydroxide and the like can be used as the material
which absorbs the replacing gas. Among them, zeolite is
preferable because the absorbing speed is high. Zeolite
having hole diameter of 1.0 nm is most suitable because
the absorbing speed of the carbon dioxide is high. Although
any shape of zeolite can be used , but spherical shape is
preferable because the zeolite of such shape is less prone
to be crushed.
Next, a connecting apparatus of the replacing gas
charging container will be explained in reference to Fig.3.
Fig.3 is a schematic view of the connecting apparatus
of the replacing gas charging container according to one
embodiment of the invention.
The connecting apparatus 30 is provided at its one
end with a connecting portion 31 which is threadedly engaged
with a male screw 81 of the refrigerant charge port 8b,
and at the other end with a connecting portion 32 which
is threadedly engaged with a male screw 21 formed on an
opening of the replacing gas charging container 20. A
female screw 33 is formed on an inner peripheral surface
of the connecting portion 31, and a female screw 34 is formed
on an inner peripheral surface of the connecting portion
32. A valve rod 35 and a seal member 36 comprising an O-ring
or the like are provided in the connecting portion 31. The
valve rod 35 abuts against a valve core 82 in the refrigerant
charge port 8b, and has enough length to push the valve
core 82. A blade 37 is formed in the connecting portion
32 such that a hole can be formed in the opening of the
replacing gas charging container 20. It is preferable that
outer diameters or inner diameters of the connecting
portion 31 and the connecting portion 32 are different so
that the refrigerant charge port 8b and the replacing gas
charging container 20 will not be erroneously connected.
Here, it is unnecessary that the screw for the refrigerant
charge port 8b and the screw for the replacing gas charging
container of the connecting apparatus 30 exist on the same
axis. If these screws exist on two axes which intersect
substantially at right angles as shown in Fig. 3, the
flexibility of positioning at work site for connecting the
replacing gas charging container 20 is greatly enhanced
so that it makes easier to remove the air in the air
conditioner by the replacing gas.
It is preferable that the connecting portion 31
connecting with the refrigerant charge port 8b is a screw
type joint because the hermeticity is ensured. In order
to further enhance the hermeticity, it is preferable to
provide a rubber seal member 36 such as the O-ring. In
this case, the female screw 33 is threadedly engaged with
the male screw 81 of the refrigerant charge port 8b. At
that time, it is preferable that the seal member 36 abuts
against the male screw 81 before the valve rod 35 pushes
the valve core 82 in the refrigerant charge port 8b, thereby
hermetically closing the space between the screws 81 and
33. This is because that the air is less prone to remain
in the refrigeration cycle. Comparably, when the screws
81 and 33 are removed, it is preferable that the seal member
36 is separated from the male screw 81 of the refrigerant
charge port 8b after the valve rod 35 and the valve core
82 are separated from each other. Here, it is further
preferable that the connecting portions 31 and 32 are
rotatably mounted on the outer peripheral surfaces of the
connecting portions 38 and 39 because it is unnecessary
to rotate the connecting portions 31 and 32 together with
the connecting apparatus 30.
The refrigerant charge port 8b is opened by pushing
the valve core 82. And, the valve core 82 is pressed to
a seat 84 by a resilient body 83 by being connected to the
resilient body 83 via the connecting portion 85.
A connecting apparatus of the replacing gas
collecting container will be explained with reference to
Fig.4.
Fig.4 is a schematic view of the connecting apparatus
of the replacing gas collecting container according to one
embodiment of the invention.
The connecting apparatus 50 is provided at its one
end with a connecting portion 51 which is threadedly engaged
with a male screw 81 of the refrigerant charge port 8b,
and at the other end with a connecting portion 52 which
is threadedly engaged with a male screw 41 formed on an
opening of the replacing gas collecting container 40. A
female screw 53 is formed on an inner peripheral surface
of the connecting portion 51, and a female screw 54 is formed
on an inner peripheral surface of the connecting portion
52. A valve rod 55 and a seal member 56 are provided in
the connecting portion 51. The valve rod 55 abuts against
a valve core 82 in the refrigerant charge port 8b, and has
enough length to push the valve core 82. A blade 57 is
formed in the connecting portion 52 such that a hole can
be formed in the opening of the replacing gas collecting
container 40. It is preferable that outer diameters or
inner diameters of the connecting portion 51 and the
connecting portion 52 are different so that the refrigerant
charge port 8b and the replacing gas collecting container
40 are not erroneously connected.
In this case also, it is preferable that the connecting
portion 51 connecting to the refrigerant charge port 8b
is a screw type joint because the hermeticity is ensured.
In order to further enhance the hermeticity, it is
preferable to provide a rubber seal member 56 such as the
O-ring. In this case, the female screw 53 is threadedly
engaged with the male screw 81 of the refrigerant charge
port 8b. At that time, it is preferable that the seal member
56 abuts against the male screw 81 before the valve rod
55 pushes the valve core 82 in the refrigerant charge port
8b, thereby hermetically closing the space between the
screws 81 and 33. This is because that the air is less
prone to remain in the refrigeration cycle. Comparably,
when the screws 81 and 53 are removed, it is preferable
that the seal member 56 is separated from the male screw
81 of the refrigerant charge port 8b after the valve rod
55 and the valve core 82 are separated from each other.
Here, it is further preferable that the connecting portions
51 and 52 are rotatably mounted on the outer peripheral
surfaces of the connecting portions 58 and 59 because, in
this manner, it is unnecessary to rotate the connecting
portions 51 and 52 together with the connecting apparatus
50.
In the above embodiments, the connecting apparatus
shown in Fig.3 was explained as the connecting apparatus
30 for connecting the replacing gas charging container 20,
and the connecting apparatus shown in Fig.4 was explained
as the connecting apparatus 50 for connecting the replacing
gas collecting container 40. However, the connecting
apparatus shown in Fig.3 can be used as the connecting
apparatus 50 for connecting the replacing gas collecting
container 40, and the connecting apparatus shown in Fig.,4
can be used as the connecting apparatus 30 for connecting
the replacing gas charging container 20. Therefore,
although the connecting apparatus 30 and the connecting
50 were explained as different members, the male screw 21
of the replacing gas charging container 20 and the male
screw 41 of the replacing gas collecting container 40 are
formed into the same size, the connecting apparatus 30 and
the connecting 50 can be a common apparatus. Further, the
refrigerant can be charged and collected using the
connecting apparatus 30 and 50.
In the connecting apparatus 30, the screw on the side
of the refrigerant charge port 8b and the screw on the side
of the replacing gas collecting container 40 are formed
on two axes which intersect substantially at right angles.
The connecting apparatus 50 may have the same structure.
A replacing gas charging container according to
another embodiment will be explained in reference to Fig.5
below.
Fig.5 is a schematic view of the replacing gas charging
container and a gas-side three-way valve according to the
embodiment.
A replacing gas comprising one kind or a plurality
of kinds of gas mixture which is inert toward the refrigerant
in the refrigeration cycle and which is gas state at room
temperature and atmospheric pressure is charged into a
replacing gas charge container 20A. The replacing gas
charge container 20A is provided with a connecting port
having a connecting portion 21A. And, the replacing gas
charge container 20A can be connected to the refrigerant
charge port 8b by the connecting portion 21A. Although
the internal structure of the connecting portion 21A is
not shown in Fig 5, the connecting portion 21 may be
constructed such that a valve core which is normally closed
by a resilient body is opened by an external pushing pressure
like the inside structure of the refrigerant charge port
8b. If the valve core is disposed in the connecting portion
21A also, the valve core on the side of the refrigerant
charge port 8b and the valve core on the side of the
connecting portion 21A push against each other, and the
respective connecting ports can be opened.
Although the replacing gas charging container was
explained in Fig.5, the replacing gas collecting container
may have the same structure.
Next, a method for installing the above-described
air conditioner will be explained.
Before the air conditioner is installed, refrigerant
gas is charged into the pipes on the side of the outdoor
A such as the compressor 1 and the outdoor unit heat exchanger
3. At that time, refrigerant gas which is necessary for
driving is charged into the outdoor unit A. On the other
hand, the pipes on the side of the indoor unit B such as
the indoor unit heat exchanger 6, as well as the connecting
pipes 9 and 10 are not sealed and are opened to the
atmosphere.
First, the outdoor unit A and the indoor unit B are
connected through the connecting pipes 9 and 10. At that
time, the liquid-side two-way valve 7 and the connecting
pipe 9 are not hermetically connected to each other but
are loosely connected such that gas can slightly leak. The
screw 7a of the liquid-side two-way valve 7 and the screw
8a of the gas-side three-way valve 8 are closed.
Next, the connecting apparatus 30 is mounted to the
refrigerant charge port 8b of the gas-side three-way valve
8. When the connecting apparatus 30 is mounted to the
refrigerant charge port 8b, the valve core 82 in the
refrigerant charge port 8b is pushed by the valve rod 35
in the connecting apparatus 30 so that the refrigerant
charge port 8b is opened. Thereafter, by mounting the
replacing gas charging container 20 to the connecting
apparatus 30, the opening of the replacing gas charging
container 20 is opened by the blade 37 of the connecting
apparatus 30. As a result, carbon dioxide in the replacing
gas charging container 20 is introduced into the connecting
pipe 10 and the indoor unit B from the refrigerant charge
port 8b through the connecting apparatus 30, and introduced
into the connecting pipe 9. By the introduced carbon
dioxide, the air in the connecting pipes 9 and 10 as well
as in the indoor unit B is discharged into the atmosphere
together with the introduced carbon dioxide from a loosened
portion of flare portion of the liquid-side two-way valve
7.
Here, confirming that gas is leaking from a space
between the liquid-side two-way valve 7 and the connecting
pipe 9 and that a predetermined amount of gas has been
discharged, then, the connecting portion between the
liquid-side two-way valve 7 and the connecting pipe 9 is
hermetically closed. The predetermined amount of
discharged gas may be measured using a flowmeter, but if
the amount of gas in the replacing gas charging container
20 is set slightly greater than the volume in the pipe in
the indoor unit B and the connecting pipes 9 and 10 so that
one air conditioner can be installed using one replacing
gas charging container 20, the connecting portion between
the liquid-side two-way valve 7 and the connecting pipe
9 may be hermetically closed when a sound of gas leaking
out becomes small without using the flowmeter.
Next, the connecting apparatus 30 is detached from
the refrigerant charge port 8b in a state where the replacing
gas charging container 20 is left mounted to the connecting
apparatus 30.
In the case that inert gas is not removed from the
air conditioner, the screw 7a of the liquid-side two-way
valve 7 and the screw 8a of the gas-side three-way valve
8 are opened in this state, and the refrigerant in the outdoor
unit A is allowed to flow into the indoor unit B.
In the case that the introduced inert gas is removed,
the screw 7a of the liquid-side two-way valve 7 and the
screw 8a of the gas-side three-way valve 8 are not opened
at this time, and the procedure proceeds to an inert gas
absorbing step as shown in Fig.2.
The inert gas absorbing step is achieved by connecting
the replacing gas collecting container 40 to the
refrigerant charge port 8b.
One method therefor is to connect the connecting
apparatus 50 to the replacing gas collecting container 40
by threadedly engaging the male screw 41 of the replacing
gas collecting container 40 with the female screw 54 of
the connecting apparatus 50. In this state, the replacing
gas collecting container 40 is opened by the blade 57 of
the connecting apparatus 50.
Then, confirming that a hole is formed in a tip end
of the replacing gas collecting container 40, the other
end of the connecting apparatus 50 is connected to the
refrigerant charge port 8b. By threadedly engaging the
connecting apparatus 50 with the refrigerant charge port
8b, the valve rod 55 of the connecting apparatus 50 pushes
the valve core 82 in the refrigerant charge port 8b. Then,
the replacing gas collecting container 40 and the
refrigerant charge port 8b are brought into communication
with each other, and the carbon dioxide in the connecting
pipes 9 and 10 as well as the pipes in the indoor unit B
is introduced from the refrigerant charge port 8b into the
replacing gas collecting container 40. By first
connecting the connecting apparatus 50 and the replacing
gas collecting container 40 in this manner, it is possible
to prevent the air in the atmosphere from mixing into the
replacing gas by the replacing gas's flowing out from the
refrigerant charge port 8b.
Another method is to first connect the other end of
the connecting apparatus 50 to the refrigerant charge port
8b and then, to connect the replacing gas collecting
container 40 to the connecting apparatus 50. By first
connecting the connecting apparatus 50 to the refrigerant
charge port 8b in this manner, the air in the connecting
apparatus 50 can be pushed out by the replacing gas.
The introduced carbon dioxide is physically absorbed
and collected by zeolite in the replacing gas collecting
container 40.
Then, the connecting apparatus 50 is detached from
the refrigerant charge port 8b, and the screw of the
liquid-side two-way valve 7 is completely opened. The
connecting apparatus 50 is detached from the refrigerant
charge port 8b in a state where the replacing gas collecting
container 40 is still connected to the connecting apparatus
50.
Lastly, the screw 8a of the gas-side three-way valve
8 is also opened completely, and the installing operation
of the air conditioner is completed.
The air in the refrigeration cycle can be removed
by carrying out the installation in accordance with the
above-described step. Further, waste space between the
outlet of replacing gas charging container 20 or the outlet
of the replacing gas collecting container 40 and the
refrigerant charge port 8b can be reduced by using the
connecting apparatus 30 and 50 of the above embodiments,
thereby, harmful air will not be mixed almost at all; the
air in the refrigeration cycle can be removed without using
a vacuum pump; and it is possible to prevent the
refrigeration cycle from being deteriorated.
Although the method for installing the outdoor unit
having the normal two-way valve and three-way valve was
explained in the above embodiments, the present invention
can also be applied to an outdoor unit having a three-way
valve and another three-way valve. Further, the present
invention should not be limited to the two-way valve and
three-way valve, and the invention can also be applied to
an air conditioner having a valve including a refrigerant
charge port.
As described above, according to the present
invention, the refrigerant charge port can be opened simply
by connecting the connecting apparatus to the refrigerant
charge port, and the replacing gas charging container can
be opened simply by connecting the replacing gas charging
container to the connecting apparatus. Therefore, the
replacing gas in the replacing gas charging container can
be allowed to flow from the refrigerant charge port simply
by connecting the connecting apparatus to the refrigerant
charge port and by connecting the replacing gas charging
container to the connecting apparatus. Therefore, the
operation for introducing the replacing gas in the
replacing gas charging container into the air conditioner
can be carried out simply by connecting the connecting
apparatus. Therefore, it is unnecessary to operate the
vacuum pump like the prior art, and even when the replacing
gas is utilized, it is unnecessary to use a large-scale
cylinder equipped with a valve, it is possible to use a
throwaway type replacing gas container having no valve and
thus, an installation operation of the air conditioner can
be greatly facilitated.
Further, according to the present invention, the
refrigerant charge port can be opened simply by connecting
the connecting apparatus to the refrigerant charge port,
and the replacing gas collecting container can be opened
simply by connecting the replacing gas collecting container
to the connecting apparatus. Therefore, the replacing gas
can be collected through the refrigerant charge port into
the replacing gas collecting container simply by connecting
the replacing gas collecting container to the connecting
apparatus and by connecting the connecting apparatus to
the replacing gas charge port. Therefore, the operation
for collecting the replacing gas from the air conditioner
into the replacing gas collecting container can be carried
out simply by connecting the connecting apparatus.
Therefore, it is unnecessary to operate the vacuum pump
like the prior art, and even when the replacing gas is
utilized, it is unnecessary to use a large-scale cylinder
equipped with a valve, it is possible to use a throwaway
type replacing gas collecting container having no valve
and thus, an installing operation of the air conditioner
can be greatly facilitated.
Further, according to the present invention, the
refrigerant charge port can be opened simply by connecting
the connecting apparatus to the refrigerant charge port
and the replacing gas charging container or the replacing
gas collecting container can be opened simply by connecting
the replacing gas charging container or the replacing gas
collecting container to the connecting apparatus.
Therefore, since both the replacing gas charging container
and replacing gas collecting container can be used, the
operation for replacing the air in the air conditioner by
the replacing gas as well operation for collecting the
replacing gas can be carried out by using this connecting
apparatus.
Furthermore, according to the present invention, the
connecting port of the connecting apparatus and the
refrigerant charge port can be connected without immixing
the air in the atmosphere.
Further, according to the present invention, since
the connecting apparatus can be screwed without rotating
the connecting apparatus itself, the operability of the
installation is excellent.
Further, according to the present invention, the
charging device can be formed into throwaway type having
no on-off valve, and the charging container can be reduced
in size.
Further, according to the present invention, the
collecting device can be formed into throwaway type having
noon-off valve, and the collecting container can be reduced
in size.
Further, the present invention has an advantage in
global environment as compared with a case in which a
refrigerant which has been charged is purged and the
refrigerant is discharged out into the atmosphere.
