Abstract
Provided is an air conditioner. The air conditioner includes a mechanical chamber receiving a compressor for compressing a refrigerant and a water-cooled heat exchanger for heat-exchanging water introduced from the outside and flowing along a water pipe with the refrigerant, an air-cooled heat exchanger disposed on a top surface of the mechanical chamber, the air-cooled heat exchanger being fluidly connected to the compressor, and a fan disposed above the air-cooled heat exchanger. A refrigerant pipe constituting the air-cooled heat exchanger is bent several times along an outer edge of the fan and has a polygonal pillar shape extending in a vertical direction.
Description
- The present disclosure relates to an air conditioner.
- In general, air conditioning systems are systems in which indoor air is cooled or heated using a refrigerant circulation cycle including compression, condensation, expansion, and evaporation processes which are successively performed.
- In a general refrigerant circulation cycle, a compressor, a condenser, an expansion member, and an evaporator are connected by refrigerant pipes to realize a closed circuit. Also, a refrigerant is heat-exchanged with air in the condenser and evaporator. That is, the refrigerant within the condenser decreases in temperature due to the heat exchange between the air and the refrigerant. Also, the refrigerant within the evaporator increases in temperature due to the heat exchange between the air and the refrigerant. Also, air cooled through the heat exchange in the evaporator may be supplied into an indoor space, and air heated through the heat exchange in the condenser may be supplied into the indoor space.
- Air conditioning systems that are water-cooled heat exchangers has been developed in recent years so that a refrigerant within one of the condenser and the evaporator is not heat-exchanged with air, but is heat-exchanged with other fluids, e.g., water. In detail, in one heat exchanger serving as a condenser or evaporator, refrigerant and water are not mixed with each other, but are heat-exchanged with each other.
- In case of combination type air conditioning systems including an air-cooled heat exchanger and water-cooled heat exchanger, the air-cooled heat exchanger is installed in an outdoor space and other system components except the air cooled heat exchanger are received in a separate case and then installed in an indoor space. Alternatively, the air cooled heat exchanger and the case may be provided as one module and then installed in the outdoor space.
-
FIG. 1 is a perspective view of an air conditioning system according to a related art. - Referring to
FIG. 1 , an air conditioning system according to a related art includes acase 2 receiving a compressor, a four-way valve, a water-cooled heat exchanger, and an expansion member, an air-cooledheat exchanger 3 installed on a top surface of thecase 2, and a fan assembly 4 for forcibly blowing air to heat-exchange the air-cooledheat exchanger 3 with air. - In detail, when the
air conditioning system 1 is operated as a heat pump, the air-cooledheat exchanger 3 may serve as a condenser in which a high-temperature high-pressure refrigerant flows. Also, when theair conditioning system 1 is operated as a cooler, the air-cooledheat exchanger 3 may serve as an evaporator in which a low-temperature low-pressure two-phase refrigerant flows. - Also, the air-cooled
heat exchanger 3 may have a V shape as shown inFIG. 1 . - However, when the air-cooled
heat exchanger 3 has the V shape, there is a limitation to increase a heat exchange area of the heat exchanger under a limited condition in a plane area of thecase 2, i.e., a bottom area of the heat exchanger. - In addition, when two (or more) fan assemblies 4 are installed on an upper end of the V-shaped heat exchanger as shown in
FIG. 1 , heat exchange efficiency may be significantly reduced in case where one of the plurality of fans may be broken down. - In detail, when a portion of the fans is broken down in the existing V-shaped heat exchanger, air existing in an outer upper side of the broken fan and air existing in a lower space of the broken fan within an inner space of the heat exchanger may flow toward the normal operating fan. As a result, air existing outside a side surface of the heat exchanger does not flow into the inner space of the heat exchanger. That is, the amount of air flowing by one normal fan may be reduced than the amount of air flowing by two normal fans. Furthermore, the amount of air sucked from the outside of the heat exchanger may be reduced. That is to say, the amount of air existing inside the V-shaped heat exchanger in air sucked by the normal operating fan may be greater than the amount of air sucked from the heat exchanger. This is done because the air sucked from the outside of the heat exchanger is affected by a flow resistance due to fins of the heat exchanger. However, air within the heat exchanger is not affected by the flow resistance.
- Thus, there is a limitation that the heat exchange is not smoothly performed in a heat exchanger region that should be covered by the normal operating fan as well as a heat exchanger region covered when the broken fan is normally operated.
- Embodiments provide an air conditioning system in which a heat exchanger is improved in shape to maximally secure a heat exchange area in comparison to a single bottom area.
- Embodiments also provide an air conditioning system in which only a heat exchange function in a heat exchange region covered by a broken fan assembly is stopped, and a heat exchange function in a heat exchange region covered by a normal operating fan is not affected by the broken fan assembly to realize normal heat exchange efficiency.
- In one embodiment, an air conditioner includes: a mechanical chamber receiving a compressor for compressing a refrigerant and a water-cooled heat exchanger for heat-exchanging water introduced from the outside and flowing along a water pipe with the refrigerant; an air-cooled heat exchanger disposed on a top surface of the mechanical chamber, the air-cooled heat exchanger being fluidly connected to the compressor; and a fan disposed above the air-cooled heat exchanger, wherein a refrigerant pipe constituting the air-cooled heat exchanger is bent several times along an outer edge of the fan and has a polygonal pillar shape extending in a vertical direction.
- In another embodiment, an air conditioner includes: a mechanical chamber receiving a compressor for compressing a refrigerant and a water-cooled heat exchanger for heat-exchanging water introduced from the outside and flowing along a water pipe with the refrigerant; an air-cooled heat exchanger disposed on a top surface of the mechanical chamber, the air-cooled heat exchanger including a plurality of heat exchange parts; and a fan disposed above the air-cooled heat exchanger, wherein the plurality of heat exchange parts include: a first heat exchange part including one bent part; and a second heat exchange part coupled to the first heat exchange part, the second heat exchange part including the other bent part, wherein the air-cooled heat exchanger has a polygonal box shape due to the coupling of the first heat exchange part and the second heat exchange part.
- The air conditioner including the above-described constitutions may realize effects as follows.
- First, even though one of the plurality of fan assemblies installed in the heat exchanger is broken down, heat exchange performance in the heat exchange region defined at a side of the other normal operating fan assembly is not affected by the broken fan assembly.
- Second, since the heat exchanger has the polygonal box (column) shape, the distance from the center of the fan assembly up to the heat exchanger in a circumference direction is constant from an upper end of the heat exchanger up to a lower end. Therefore the uniform flow rate may be secured in the whole heat exchanger.

-
FIG. 2 is a perspective view illustrating an outer appearance of an air conditioning system according to an embodiment.FIG. 3 is a view illustrating constitutions of the air conditioning system. - Referring to
FIGS. 2 and 3 , an air conditioning system according to an embodiment is a combination-type system in which a water-cooled heat exchanger and an air-cooled heat exchanger are used together with each other. That is, the air conditioning system may heat or cool indoor air using water cooled or heated by heat-exchanging with a refrigerant used in a refrigeration cycle or may be used for providing cool and warm water. - In detail, the
air conditioning system 10 according to the current embodiment includes acase 101 for receiving components used for the refrigeration cycle and an air-cooledheat exchanger 15 disposed outside of thecase 101, i.e., a top surface of thecase 101. Also, the components constituting theair conditioning system 10 are connected to each other byrefrigerant pipes 16 to realize a closed circuit. - In more detail, the
air conditioning system 10 includes a compressor for compressing the refrigerant at a high-temperature high-pressure, a four-way valve 12 disposed at an outlet side of thecompressor 11 to convert a flow direction of the refrigerant, a water-cooledheat exchanger 13 connected to one of outlets of the four-way valve 12, anexpansion member 14 connected to an outlet side of the water-cooledheat exchanger 13, and an air-cooledheat exchanger 15 connected to an outlet side of theexpansion member 14. - An outlet end of the air-cooled
heat exchanger 15 is connected to the other one of the outlets of the four-way valve 12. Also, awater utilizer 20 using water as an operation fluid is connected to the water-cooledheat exchanger 13 by awater pipe 17. Thewater utilizer 20 may include an air conditioner installed in an indoor space to cool or heat indoor air or an indoor bottom or a hot/cold water dispenser for supplying cold and hot water. - Also, the four-
way valve 12 may be disposed on the outlet side of thecompressor 11 so that a high-temperature high-pressure refrigerant discharged from thecompressor 11 flows toward one of the water-cooledheat exchanger 13 and the air-cooledheat exchanger 15 according to an operation mode. - A
fan 151 is disposed on a side of the air-cooledheat exchanger 15 to heat-exchange external air with a refrigerant flowing into the air-cooledheat exchanger 15. Here, a heat exchange assembly constituted by the air-cooledheat exchanger 15 and thefan 151 may be disposed outside thecase 101, and other components except the water utilizer may be received into thecase 101. The heat exchanger assembly may be provided in plurality on thecase 101. - Also, the water-cooled
heat exchanger 13 may have a structure in which only the heat exchange is performed without mixing the refrigerant circulating the refrigerant circulation cycle and the water flowing along thewater pipe 17. For example, a plate-type heat exchanger well known in the related art may be used as the water-cooledheat exchanger 13. Also, as shown inFIG. 2 , a chiller in which a refrigerant is introduced into a cylindrical case and a water pipe meanderingly bent in several times in an S shape within the cylindrical case is received may be used as the water-cooled heat exchanger. In detail, the water pipe is received into the case of the chiller and a refrigerant is filled into the case of the chiller. Thus, water flowing along the inside of the water pipe is heat-exchanged with the refrigerant filled into the case of the chiller without being mixed with the refrigerant. - In detail, a
refrigerant suction port 13 a may be disposed on one side of the chiller, and arefrigerant discharge port 13 b may be disposed on the other side of the chiller. A refrigerant pipe extending from the four-way valve 12 is connected to therefrigerant suction port 13 a. Therefrigerant discharge port 13 b is connected to an inlet of theexpansion member 14 by the refrigerant pipe. - Also, a high-temperature high-pressure refrigerant discharged from the
compressor 11 may be supplied into the water-cooledheat exchanger 13 or a low-temperature low-pressure two-phase refrigerant discharged from theexpansion member 14 may be supplied into the water-cooledheat exchanger 13 according to a state of the four-way valve 12. - Here, a flow direction of the refrigerant may be decided according to the converted state of the four-
way valve 12. For example, a flow of the refrigerant when theair conditioning system 10 performs a heating cycle operation such as a heat pump is as follows. - In detail, a flow direction of a supersaturated gaseous refrigerant compressed at a high-temperature high-pressure by the
compressor 11 is decided by the four-way valve 12 to flow into the water-cooledheat exchanger 13. Also, the refrigerant passing through the water-cooledheat exchanger 13 may be changed in phase into a two-phase refrigerant while passing through theexpansion member 14. Also, the refrigerant passing through theexpansion member 14 is changed in phase into a low-temperature low-pressure saturation refrigerant while passing through the air-cooledheat exchanger 15. Then, the low-temperature low-pressure saturation refrigerant returns to thecompressor 11 via the four-way valve 12. Here, a process in which the refrigerant and the water are heat-exchanged with each other is performed in the water-cooledheat exchanger 13. That is, the water introduced into the water-cooledheat exchanger 13 along thewater pipe 17 may absorb heat from the high-temperature high-pressure refrigerant and thus be heated to return to thewater utilizer 20. Thewater utilizer 20 may be used as an indoor heater or a hot water dispenser. - A flow of the refrigerant when the
air conditioning system 10 performs a cooling cycle operation such as an air conditioner is as follows. - In detail, a flow direction of a supersaturated gaseous refrigerant compressed at a high-temperature high-pressure by the
compressor 11 is decided by the four-way valve 12 to flow into the air-cooledheat exchanger 15. The refrigerant introduced into the air-cooledheat exchanger 15 is heat-exchanged with air and thus changed in phase into a high-temperature high-pressure liquid state. Also, the refrigerant is changed in phase into a low-temperature low-pressure two-phase refrigerant while passing through theexpansion member 14. Also, the refrigerant absorbs heat from the water flowing along thewater pipe 17 and thus is changed in phase into a low-temperature low-pressure saturation refrigerant while passing through the water-cooledheat exchanger 13. Also, the refrigerant passing through the water-cooledheat exchanger 13 returns to thecompressor 11 via the four-way valve 12. Here, heat of the water flowing along thewater pipe 17 is lost into the refrigerant and thus cooled. Thus, thewater utilizer 20 may be used as a cooler or a cold water dispenser. - As shown in drawings, the air-cooled
heat exchanger 15 may have a polygonal pillar shape. Although the air-cooledheat exchanger 15 has a hexagonal pillar shape in the current embodiment, the present disclosure is not limited thereto. For example, the air-cooled heat exchanger may have a polygonal pillar shape including the hexagonal pillar shape as well as a cylindrical shape. - The air-cooled
heat exchanger 15 has a box shape. Also, the air-cooledheat exchanger 15 may be constituted by a set of one fan and one heat exchanger having the box shape. Thus, even though one of the plurality of fans is broken down, other normal operating fans and the heat exchange set are not affected by the broken fan. That is, heat exchange efficiency may be reduced in the aspects of the whole heat exchanger. However, the heat exchange may be normally performed in the heat exchanger disposed at a side of the normal operating fan without being affected by the broken fan. - In addition, since the heat exchanger has the box shape, a distance (the shortest distance) from a line vertically extending with respect to a center of the fan up to any position of the heat exchanger may be constantly maintained in a length direction of the heat exchanger. Thus, a uniform flow rate may be secured in the whole heat exchanger.
- Hereinafter, a structure of the heat exchanger having a polygonal box shape will be described in detail. For example, a heat exchanger having a hexagonal box shape will be described.
-
FIG. 4 is a plan view illustrating a set of a fan and heat exchanger according to a first embodiment.FIG. 5 is a view illustrating constitutions of a heat exchange part according to the first embodiment. - Referring to
FIGS. 4 and 5 , an air-cooledheat exchanger 15 of an air conditioning system according to a first embodiment has a structure in which first and secondheat exchanger parts heat exchange parts heat exchange part 110 will be described. Here, the first and secondheat exchange parts - The first
heat exchange part 110 includes a plurality ofmain pipes 111 extending in a horizontal direction and spaced a predetermined distance from each other in a vertical direction and ⊂-shapedreturn bands 112 connecting ends of themain pipes 111 adjacent to each other in a vertical direction to each other. Thereturn bands 114 may be disposed on an end of one side of themain pipe 112 and an end of the other side of themain pipe 112, respectively. - Since the
main pipes 111 and thereturn bands 112 are coupled to each other, the refrigerant pipes constituting the firstheat exchange part 110 may be meanderingly connected to each other in an S shape to form a meander line. Also, the refrigerant pipe manufactured by connecting themain pipes 11 to thereturn bands 112 passes through a plurality ofcooling fin 115. - Each of the
main pipes 111 includes a plurality ofbent parts bent parts bent part 113 disposed at one portion of themain pipe 111 and a secondbent part 114 disposed at the other portion of themain pipe 114. Since the plurality ofbent parts heat exchanger 15 may have a plurality of side surfaces facing a plurality of directions. Thus, air may be heat-exchanged while passing through the plurality of side surfaces. - Although the
heat exchanger 15 has the hexagonal box shape to provide the two bent parts in the current embodiment, the present disclosure is not limited thereto. For example, when theheat exchanger 15 has an octagonal box shape, themain pipe 111 may include three bent parts. In summary, thefirst heat exchanger 110, i.e., themain pipe 111 may include at least two bent parts. - For example, when the
main pipe 111 includes two or more bent parts, lines of the polygonal shape may have an angle (see reference symbol a ofFIG. 6 ) less than about 180 degrees with respect to one another. - Also, the
return band 112 disposed at one side of the firstheat exchange part 110 is disposed adjacent to thereturn band 120 disposed at one side of the secondheat exchange part 120, for example. For example, the tworeturn bands 112 may contact each other. However, the present disclosure is not limited thereto. For example, the two return bands may be disposed more close to each other. Also, thereturn band 112 disposed at the other side of the firstheat exchange part 110 may be disposed more close to the return band disposed at the other side of the secondheat exchange part 120. - In summary, the
return bands 112 disposed on both side ends of the firstheat exchange part 110 and thereturn bands 112 disposed on both side ends of the secondheat exchange part 120 are disposed adjacent to each other. Thus, a horizontal section of theheat exchanger 15 may have a polygonal plane. - Also, since the first and second
heat exchange parts return band 112 of the firstheat exchange part 110 and the return band of the secondheat exchange part 120 are more adjacent to each other, aninner region 130 defined by the first and secondheat exchange parts - Here, the “closed space” may be understood as that the closed space is not opened in side directions and also external air should pass through the
heat exchanger 15 to flow into theinner region 130. - As described above, both side ends of the first and second
heat exchange parts heat exchanger 15 may have a polygonal shape in plane (hexagonal plane in the current embodiment). - That is, in a state where the fan is provided above the
heat exchanger 15 and thecase 101 is provided under theheat exchanger 15, the side surfaces of theheat exchanger 15 may be closed by the first and secondheat exchange parts - Also, as the
fan 151 is operated, air may flow from the outside of the air-cooledheat exchanger 15 toward the inside (an arrow direction). Thus, the air is heat-exchanged with the refrigerant within the heat exchanger due to the air flow formed by thefan 151. - Referring to
FIG. 4 , when thefan 151 disposed above theheat exchanger 15 is rotated, side ends of thefan 151 may definepredetermined rotation regions 153. Therotation region 153 may be understood as a virtual region (area) corresponding to a rotation radius of thefan 151. - The
rotation region 153 may be understood as a region included in a sectional area in a horizontal direction of theinner region 130, i.e., the hexagonal area ofFIG. 4 . That is, therotation region 153 is less than the hexagonal area. - Also, the rotation region has a diameter D corresponding to the longest distance defined between at least portion of the first
heat exchange part 110 and at least portion of the secondheat exchange part 120. That is to say, as shown inFIG. 4 , twopoints heat exchange part 110 and the secondheat exchange part 120, respectively. - According to the above-described structure, the external air may smoothly flow by a driving force of the
fan 151. - Also, since the fan and the heat exchanger are independently provided as one assembly, the normal operating fan and the heat exchanger is not affected by the broken fan even though one fan of the plurality of fans is broken down.
- Hereinafter, a description will be made according to a second embodiment. Since the current embodiment is the same as the first embodiment except for a portion of the heat exchanger in structure, different parts between the first and second embodiments will be described principally, and descriptions of the same parts will be denoted from the descriptions and reference numerals of the first embodiment.
-
FIG. 6 is a plan view illustrating a set of a fan and heat exchanger according to a second embodiment. - Referring to
FIG. 6 , an air-cooling heat exchanger 15 according to the current embodiment has a structure in which main pipes and return bands are coupled to each other to realize a refrigerant pipe and the refrigerant pipe passes through a plurality of cooling fins, like the structure of the foregoing embodiment. - However, unlike the structure in which the air-cooled heat exchanger includes the first and second
heat exchange parts heat exchanger 15 according to the current embodiment has a structure in which a single heat exchanger is bent several times (four times inFIG. 6 ), and one side thereof end and the other side end are disposed adjacent to each other. - That is to say, a structure in which a pair of symmetric heat exchangers are disposed adjacent to each other to define one polygonal shape is not provided, but a structure in which one heat exchanger is bent several times to define one polygonal shape is provided. That is, the pair of
heat exchangers - Thus, the return band disposed on one side end and the return band disposed on the other side ends are disposed adjacent to and facing each other. Here, the return bands of both side ends are disposed adjacent to and crossing each other at an angle α less than about 180 degrees.
- As described above, the
heat exchanger 15 is disposed under thefan 151 to define a closed space and extends in a vertical direction. Thus, external air certainly passes through theheat exchanger 15 while flowing into an inner space of theheat exchanger 15 by a driving force of thefan 151. Therefore, a heat exchange area may increase. - In the air conditioning system according to the embodiments, even though one of the plurality of fan assemblies installed in the heat exchanger is broken down, heat exchange performance in the heat exchange region defined at a side of the other normal operating fan assembly is not affected by the broken fan assembly.
