[0040] Hereinafter, one embodiment is described in detail with reference to the attached drawings.

[0041] FIG. 1 is a schematic diagram illustrating a heat pump according to one embodiment of the present disclosure.

[0042] Referring to FIG. 1, for example, a heat pump (1) may include an outdoor unit (200) including a compressor, an expansion valve, and a heat exchanger. The heat pump (1) may include an indoor unit (600) connected to the outdoor unit (200) through a refrigerant pipe (60).

[0043] In the outdoor unit (200), refrigerant that is designed to be heated by passing through a compressor, expansion valve, and heat exchanger can flow. For example, the outdoor unit (200) can be placed outdoors and designed to exchange heat with outdoor air.

[0044] For example, the outdoor unit (200) can perform heat exchange between the refrigerant and the outdoor air by utilizing the phase change of the refrigerant (e.g., evaporation or condensation). For example, the outdoor unit (200) can absorb heat from the outdoor air into the refrigerant by utilizing the evaporation of the refrigerant. Additionally, the outdoor unit (200) can release heat from the refrigerant into the outdoor air by utilizing the condensation of the refrigerant.

[0045] Although one outdoor unit is illustrated in FIG. 1, the number of outdoor units is not limited by that illustrated in FIG. 1. For example, the heat pump may include multiple outdoor units (200).

[0046] The refrigerant can flow between the outdoor unit (200) and the indoor unit (600) through the refrigerant pipe (60). The refrigerant pipe (60) may include a refrigerant supply pipe (61) provided to supply refrigerant from the outdoor unit (200) to the indoor unit (600), and a refrigerant recovery pipe (62) provided to recover refrigerant from the indoor unit (600) to the outdoor unit (200).

[0047] For example, refrigerant heated in an outdoor unit (200) can flow to an indoor unit (600) through a refrigerant supply pipe (61). Thereafter, the refrigerant can be cooled by exchanging heat with indoor air through a heat exchanger provided in the indoor unit (600). The refrigerant that has completed heat exchange with indoor air can be returned to the outdoor unit (200) through a refrigerant recovery pipe (62).

[0048] An indoor unit valve (620) may be installed in the refrigerant supply pipe (61). The indoor unit valve (620) is configured to be openable and closeable, and can control the flow of refrigerant flowing in the refrigerant supply pipe (61). For example, when the indoor unit (600) is in operation and refrigerant needs to be supplied to the indoor unit (600), the indoor unit valve (620) may be opened, and the refrigerant may flow from the outdoor unit (200) to the indoor unit (600).

[0049] Afterwards, when the operation of the indoor unit (600) is stopped, the indoor unit valve (620) can be closed to block the supply of refrigerant from the outdoor unit (200) to the indoor unit (600).

[0050] The heat pump (1) may include an outdoor unit (200) and a distribution unit (100) connected via a water pipe (P). As will be described later, the distribution unit (100) may be arranged to distribute heating water to heating units (300, 400, 500) that heat heating locations requiring heating.

[0051] For example, the heating water may be arranged to be heated in an outdoor unit (200). For example, the heating water may be heated by heat exchange with a refrigerant heated through a heat exchanger of the outdoor unit (200).

[0052] The above is merely one example of the various methods by which heating water is heated. It is also conceivable that the heating water may be heated through a separate heating device installed indoors. Below, a method by which heating water is heated through an outdoor unit (200) will be described as an example.

[0053] The water pipe (P) is provided to connect the outdoor unit (200) and the distribution unit (100) to each other, and may include a heating water pipe (10) through which heating water can flow.

[0054] The heating water pipe (10) may include a heating water supply pipe (11) provided to supply heated heating water from the outdoor unit (200) to the distribution unit (100), and a heating water return pipe (12) provided to return heating water from the distribution unit (100) to the outdoor unit (200). For example, the heating water supply pipe (11) and the heating water return pipe (12) may be connected to the distribution unit (100) through the upper side of a cabinet (110) forming the outer shape of the distribution unit (100). A detailed description thereof will be provided later.

[0055] For example, the distribution unit (100) may be placed in an indoor space (O). Accordingly, the heating water supply pipe (11) and the heating water return pipe (12) may be arranged to connect the outdoor unit (200) installed outdoors and the distribution unit (100) installed indoors. In other words, a portion of the heating water supply pipe (11) and the heating water return pipe (12) may be configured to extend into the outdoor space, and another portion may extend into the indoor space (O).

[0056] For example, a heating unit (300, 400, 500) may be configured to supply thermal energy to a location requiring heating by utilizing heating water. Additionally, heating water may be directly supplied to a location requiring hot water.

[0057] The heating unit (300, 400, 500) may include a first heating unit (300). For example, the first heating unit (300) may include a hot water supply unit (300). For example, the first heating unit (300) may be installed indoors.

[0058] The hot water unit (300) can be arranged to directly provide heated heating water to the user according to the user's request.

[0059] The water pipe (P) is provided to connect the distribution unit (100) and the first heating unit (300) to each other, and may include a first water pipe (30) through which heating water can flow. For example, the first supply pipe (31) and the first return pipe (32) may be connected to the distribution unit (100) through the upper side of the cabinet (110) forming the outer shape of the distribution unit (100). A detailed description thereof will be provided later.

[0060] The first water pipe (30) may include a first supply pipe (31) provided to supply heating water from the distribution unit (100) to the first heating unit (300), and a first return pipe (32) provided to recover heating water from the first heating unit (300) to the distribution unit (100).

[0061] For example, a first heating valve (310) may be installed in the first supply pipe (31) to open and close the first supply pipe (31) according to the user's request.

[0062] When the first heating valve (310) opens the first supply pipe (31), heating water may be discharged from the first heating unit (300). When the first heating valve (310) closes the first supply pipe (31), heating water may not be discharged from the first heating unit (300).

[0063] The heating unit (300, 400, 500) may include a second heating unit (400). For example, the second heating unit (400) may be installed indoors.

[0064] For example, the second heating unit (400) may include a device configured to heat an indoor space (O) by exchanging heat of heating water with indoor air. For example, the second heating unit (400) may include a radiator (410) configured to exchange heat with indoor air.

[0065] The water pipe (P) is provided to connect the distribution unit (100) and the second heating unit (400) to each other, and may include a second water pipe (40) through which heating water can flow. For example, the second supply pipe (41) and the second return pipe (42) may be connected to the distribution unit (100) through the upper side of the cabinet (110) forming the outer shape of the distribution unit (100). A detailed description thereof will be provided later.

[0066] The second water pipe (40) may include a second supply pipe (41) provided to supply heating water from the distribution unit (100) to the second heating unit (400), and a second return pipe (42) provided to recover heating water from the second heating unit (400) to the distribution unit (100).

[0067] For example, the second heating unit (400) may include a second heating valve (420) operable to open and close the second supply pipe (41) according to the user's request. When the second heating valve (420) opens the second supply pipe (41), heating water may be discharged from the second heating unit (400). When the second heating valve (420) closes the second supply pipe (41), heating water may not be discharged from the second heating unit (400).

[0068] The second heating unit (400) may include a second heating unit controller (430) configured to control the operation of the second heating valve (420) and the operation of the radiator (410).

[0069] The user can control the second heating unit controller (430), thereby controlling the operation of the second heating valve (420) and the radiator (410).

[0070] The heating units (300, 400, 500) may include a third heating unit (500). For example, the third heating unit (500) may be installed indoors. The third heating unit (500) may include an underfloor heater (510).

[0071] For example, the third heating unit (500) may be arranged to heat the floor of the space where the underfloor heater (510) is installed through the heat of the heating water. That is, the underfloor heater (510) may be installed so as to pass through the floor where the third heating unit (500) is installed.

[0072] The water pipe (P) is provided to connect the distribution unit (100) and the third heating unit (500) to each other, and may include a third water pipe (50) through which heating water can flow.

[0073] For example, the third supply pipe (51) and the third return pipe (52) can be connected to the distribution unit (100) through the upper side of the cabinet (110) forming the outer shape of the distribution unit (100). A detailed description thereof will be provided later.

[0074] The third water pipe (50) may include a third supply pipe (51) provided to supply heating water from the distribution unit (100) to the third heating unit (500), and a third return pipe (52) provided to recover heating water from the third heating unit (500) to the distribution unit (100).

[0075] For example, the third heating unit (500) may include a third heating valve (520) operable to open and close the third supply pipe (51) according to the user's request.

[0076] When the third heating valve (520) opens the third supply pipe (51), heating water may be discharged from the third heating unit (500). When the third heating valve (520) closes the third supply pipe (51), heating water may not be discharged from the third heating unit (500).

[0077] The third heating unit (500) may include a third heating unit controller (530) configured to control the operation of the third heating valve (520) and the underfloor heater (510). A user may control the third heating unit controller (530), thereby controlling the operation of the third heating valve (520) and the underfloor heater (510).

[0078] The types of heating units and the methods of supplying heat energy to heating locations mentioned above are merely examples, and it goes without saying that heating units can be installed and operated in various locations requiring heating and hot water supply.

[0079] FIG. 2 is a drawing showing a heat pump according to one embodiment of the present disclosure, with the distribution unit and the water pipe separated.

[0080] FIG. 3 is a drawing showing the distribution unit and the water pipe of FIG. 2 from another angle according to one embodiment of the present disclosure.

[0081] Referring to FIGS. 2 and 3, the distribution unit (100) may include a cabinet (110) forming an outer shape. A machine room (118, see FIG. 4) may be formed inside the cabinet (110).

[0082] The cabinet (110) may include a front panel (111) forming the front (+X direction) surface, side panels (120, 150) forming both side surfaces (+-Y direction), and a rear panel (112) forming the rear (-X direction) surface.

[0083] The front panel (111) and the side panels (120, 150) can be formed so that their heights (H1) correspond. The height (H1-H2) of the rear panel (112) can be formed lower than the height (H1) of the front panel (111) and the side panels (120, 150).

[0084] An operating unit (101) formed to face forward (+X direction) may be arranged on the front panel (111). The operating unit (101) may be connected to the indoor space (O) through a front panel opening (102, see FIG. 4) formed on the front panel (111).

[0085] For example, a user can control the operation of the distribution unit (100) through the control unit (101). For example, controlling the operation of the distribution unit (100) may include controlling the opening and closing of the first heating valve (310), the second heating valve (420), and the third heating valve (520). For example, the control unit (101) may be configured to display information about the distribution unit (100).

[0086] The side panels (120, 150) may include a first side panel (150) forming the right (-Y direction) side of the distribution unit (100) and a second side panel (120) forming the left (+Y direction) side of the distribution unit (100).

[0087] The first side panel (150) may include a first side panel body (151) forming an outer shape. The first side panel (150) may include a first upper folded surface (151a) formed by folding the upper surface of the first side panel body (151) to the left (+Y direction).

[0088] The first side panel (150) may include a first side end folded surface (151b) formed by folding the rear (-X direction) side end surface of the first side panel body (151) to the left.

[0089] The first side panel body (151) has a shape in which the end is bent rather than a general plate shape due to the first upper bending surface (151a) and the first side end bending surface (151b), so that the plate shape can secure rigidity compared to the case, and thereby prevent the first side panel body (151) from being deformed by an external force.

[0090] The first side panel (150) may include a first opening cover (152) located on the upper side (+Z side) of the rear (-X direction) of the first side panel body (151).

[0091] The first opening cover (152) can be formed to cover the first opening (154, described later) formed to penetrate the first side panel body (151). A detailed description thereof will be described later.

[0092] The second side panel (120) may include a second side panel body (121) forming an outer shape. The second side panel (120) may include a second upper folded surface (121a) formed by folding the upper surface of the second side panel body (121) to the right (+Y direction).

[0093] The second side panel (120) may include a second side end folded surface (121b) formed by folding the rear side end surface of the second side panel body (121) to the right.

[0094] The second side panel body (121) has a shape in which the end is bent rather than a general plate shape due to the second upper bending surface (121a) and the second side end bending surface (121b), so that rigidity can be secured compared to a plate shape, and thereby the phenomenon in which the second side panel body (121) is deformed due to external force can be prevented.

[0095] The second side panel (120) may include a second opening cover (122) positioned on the upper rear side of the second side panel body (121). The second opening cover (122) may be formed to cover a second opening (124, described later) formed to penetrate the second side panel body (121).

[0096] The distribution unit (100) may be placed in an indoor space (O) such that the rear panel (112) faces the indoor wall (W). For example, the distribution unit (100) may be placed such that the rear panel (112) is adjacent to the wall (W). For example, the distribution unit (100) may be placed such that the rear panel (112) is in contact with the wall (W).

[0097] The distribution unit (100) may include a first cover (130) installed on the upper part of the cabinet (110) and covering a part of the machine room (118), and a second cover (140) connected to the first cover (130) to cover another part of the machine room (118).

[0098] For example, the first cover (130) can be arranged to cover the upper (+Z side) front (+X direction) of the machine room (118).

[0099] The first cover (130) may include a cover portion (131) that covers the machine room (118) and an extension portion (132) that is bent downward (in the -Z direction) from the cover portion (131).

[0100] The cover part (131) can be supported by being joined to the front panel (111) at one end (131a). The cover part (131) can have a shape roughly like a plate and can be arranged to cover the upper front of the machine room (118).

[0101] The cover portion (131) may extend in the left-right direction (+-Y direction) to be adjacent to a pair of side panels (120, 150). For example, the cover portion (131) may be positioned adjacent to the upper surface of each of the pair of side panels (120, 150).

[0102] The length of the cover part (131) in the front-back direction may be set shorter than the length of the pair of side panels (120, 150) in the front-back direction. The front end of the cover part (131) may be arranged adjacent to the front end of the side panel (120, 150).

[0103] The extension portion (132) may be formed to be bent downward from the other end (131b) of the cover portion (131). For example, the other end (131b) of the cover portion (131) may refer to an end of the cover portion (131) in the rearward direction. The upper end (132b) of the extension portion (132) may be coupled to the other end (131b) of the cover portion (131). The extension portion (132) may also have a shape roughly similar to a plate.

[0104] The extension portion (132) can extend left and right to be adjacent to the side panels (120, 150) of one side. The extension portion (132) can be formed integrally with the cover portion (131), but it goes without saying that the cover portion (131) and the extension portion (132) can be formed as separate, detachable components.

[0105] Since the extension portion (132) extends downward from the rear end of the cover portion (131), the extension portion (132) can be extended toward the machine room (118). Accordingly, the extension portion (132) can be extended such that the lower end of the extension portion (132) faces the machine room (118).

[0106] For example, the second cover (140) can be formed integrally with the first cover (130).

[0107] The second cover (140) may be formed to extend toward the rear (-X direction). The other end (141a) of the second cover facing toward the rear may be coupled to the rear panel (112) of the cabinet (110). The length of the second cover (140) in the left-right direction may correspond to the length of the first cover (130) in the left-right direction.

[0108] Since the second cover (140) is positioned lower than the first cover (130), the second cover (140) may be positioned between the upper and lower surfaces of the side panels (120, 150). For example, the height at which the second cover (140) is positioned may be the height (H1-H2) obtained by subtracting the length (+H2) by which the extension (132) of the first cover (130) extends from the height (H1) of the cabinet (110).

[0109] The second cover (140) may include a second cover body (141) forming an outer shape. The second cover (140) may be connected to water pipes (P). More specifically, the second cover (140) may include a plurality of through holes (144a, 144b, 145a, 145b, 146a, 146b, 147a, 147b) formed to allow the water pipes (P) to pass through.

[0110] A plurality of through holes (144a, 144b, 145a, 145b, 146a, 146b, 147a, 147b) may be formed to penetrate the second cover body (141). The distribution unit (100) may include a bracket (13) configured to connect the water pipe (P) and the through holes to each other. The bracket (13) may include a plurality of brackets (13) installed in each of the plurality of through holes (144a, 144b, 145a, 145b, 146a, 146b, 147a, 147b).

[0111] Some of the water pipes (P) may be arranged in the machine room (118). Other parts of the water pipes (P) may extend to the outside of the machine room (118) by penetrating the second cover (140) through the plurality of through holes (144a, 144b, 145a, 145b, 146a, 146b, 147a, 147b) described above.

[0112] The water pipes (P) penetrating the second cover (140) can extend upward and then extend in a direction intersecting the vertical direction (+-X direction).

[0113] The heat pump (1) may include a pipe space (S) through which water pipes (P) passing through the second cover (140) pass.

[0114] More specifically, the piping space (S) can be defined as a space surrounded by an extension (132) of the first cover (130), the first side panel (150), the second side panel (120), and the second cover (140). For example, the piping space (S) can have an approximately rectangular solid shape.

[0115] The piping space (S) may be formed on the upper rear side of the distribution unit (100). The piping space (S) may be formed to be open toward the upper side (+Z direction) and the rear side (-X direction). For example, when the rear panel (112) of the distribution unit (100) is arranged adjacent to the indoor wall surface (W), the rear side of the piping space (S) may be covered by the wall surface (W).

[0116] The vertical length of the pipe space (S) may roughly correspond to the vertical extension length (H2) of the extension portion (132). Accordingly, the water pipes (P) that pass through the second cover (140) can pass through the cover portion (131) of the first cover (130) after being extended by the vertical length of the pipe space (S).

[0117] Therefore, even if the distribution unit (100) is installed in a room with a low ceiling height, the water pipes (P) can secure an extendable distance equivalent to the length in the vertical direction of the pipe space (S).

[0118] A portion of the side panel (120, 150) forming the pipe space (S) may include an opening communicating with the pipe space (S) (see FIG. 10). A user can easily access the water pipes (P) extending from the pipe space (S) through the openings (124, 154, see FIG. 10) to maintain and repair the water pipes (P) (M1, M2). The openings (124, 154) may be covered with opening covers (122, 152). A detailed description thereof will be provided later.

[0119] FIG. 4 is a drawing showing a heat pump according to one embodiment of the present disclosure, with the distribution unit and the water pipe separated, and the distribution unit disassembled.

[0120] FIG. 5 is a drawing showing a disassembled view of a part of a distribution unit in a heat pump according to one embodiment of the present disclosure.

[0121] Referring to FIGS. 4 and 5, the cabinet (110) may include a lower panel (114). The lower panel may form the lower surface of the cabinet (110).

[0122] The distribution unit (100) may include a machine room (118) formed inside the cabinet (110).

[0123] For example, the machine room (118) can be defined as a space formed by a front panel (111), a pair of side panels (120, 150), a lower panel (114), a rear panel (112), a first cover (130), and a second cover (140).

[0124] The distribution unit (100) may include a tank (115) placed in the machine room (118). For example, water pipes (P) may be connected to the tank (115). For example, the tank (115) may contain excess heating water.

[0125] The water pipe (P) may include a tank connection pipe (115a, 115b) connected to the tank (115). Heating water may be introduced from the outside into the tank (115) through the tank connection pipe (115a, 115b). Heating water may be discharged from the tank (115) to the outside through the tank connection pipe (115a, 115b).

[0126] The distribution unit (100) may include a filter device (117) configured to be in communication with a water pipe (P). The filter device (117) may be configured to filter foreign substances contained in heating water passing through the filter device (117).

[0127] For example, the water pipe (P) may include a filter device connection pipe (117a, 117b) that is connected to the filter device (117). For example, heating water flowing from the outside to the distribution unit (100) through the water pipe (P) may be arranged to pass through the filter device (117).

[0128] The distribution unit (100) may include an auxiliary heater (116) configured to be in communication with a water pipe (P). The water pipe (P) may include an auxiliary heater connection pipe (116a, 116b) that is in communication with the auxiliary heater (116). The auxiliary heater (116) may be configured to heat heating water passing through the auxiliary heater (116).

[0129] Accordingly, even if the temperature of the heating water flowing from the outside to the distribution unit (100) is lowered, the temperature required for the heating location can be maintained by passing through the auxiliary heater.

[0130] The heating unit (300, 400, 500) may include a front section (103) in which an operating unit (101) is installed. The front section (103) may include a printed circuit board and various electronic components mounted on the printed circuit board.

[0131] The front panel (103) can be arranged so that the operating unit (101) is in communication with the front panel opening (102). This allows the user to control the operation of the distribution unit (100) by operating the operating unit (101).

[0132] For example, the front part (103) may be arranged so that the height in the vertical direction (+-Z direction) at which the upper end of the front part (103) is positioned is higher than the height at which the second cover (140) is positioned. In other words, the front part (103) may be arranged so that the height at which the upper end of the front part (103) is positioned is higher than the height at which the second cover body (141) is positioned.

[0133] For example, the electric part (103) may be arranged so that the height in the vertical direction (+-Z direction) where the upper end of the electric part (103) is located is lower than the height of the cover part (131) of the first cover (130). For example, the electric part (103) may be arranged so that the position in the vertical direction (+-Z direction) of the upper end of the electric part (103) is located between the vertical position of the cover part (131) and the vertical position of the second cover body (141).

[0134] For example, the second cover (140) may be a separate configuration that is detachably coupled with the first cover (130). For example, the second cover (140) may be coupled with the extension (132) of the first cover (130). More specifically, one end (141b) of the second cover facing forward (in the +X direction) may be configured to be coupled with the lower end (132a) of the extension (132) of the first cover (130) facing downward (in the -Z direction).

[0135] The second cover (140) may include second cover support members (142) extending upward from both left and right ends of the second cover body (141). For example, the second cover support members (142) may have an approximately rectangular shape, but are not limited thereto.

[0136] The second cover supports (142) may be provided to support the second cover (140) by being coupled with the side panels (120, 150). For example, the second cover supports (142) may be provided to be coupled with the first side panel (150) and the second side panel (120), respectively.

[0137] The second cover support (142) may include a support opening (143).

[0138] The support opening (143) can be formed to penetrate the second cover support (142). The support opening (143) can be connected to the pipe space (S).

[0139] The support opening (143) can be communicated with the opening of the side panel (120, 150) to be described later. Therefore, the indoor space can be communicated with the piping space (S) through the opening and the support opening (143).

[0140] FIG. 6 is a drawing showing a side panel of a distribution unit (100) in a heat pump according to one embodiment of the present disclosure.

[0141] FIG. 7 is an enlarged view of a portion of the side panel of FIG. 6 according to one embodiment of the present disclosure.

[0142] FIG. 8 is a drawing showing an enlarged portion of a portion of FIG. 7 according to one embodiment of the present disclosure.

[0143] Below, the side panels will be illustrated and described with the first side panel (150) as the center. It goes without saying that the description of the side panels described below can be equally applied to the second side panel (120).

[0144] Referring to FIGS. 6 to 8, the first side panel (150) may include a first opening (154) formed to penetrate the first side panel body (151), a first opening cover (152) covering the first opening (154), and a hole (160) formed on the outside of the first opening (154) and penetrating the first side panel body (151) to be connected to the opening. For example, the first opening cover (152) may be formed integrally with the first side panel body (151).

[0145] The first opening (154) can be formed by penetrating a part of the first side panel body (151) forming the piping space (S).

[0146] For example, the first opening (154) may be formed on the upper rear side of the first side panel body (151). The first opening (154) may have an approximately rectangular shape, but is not limited thereto.

[0147] The first opening cover (152) may be configured to cover a portion of the first opening (154). The first opening cover (152) may be supported on the first side panel body (151) by a connecting tip (159) connected to the first side panel (150).

[0148] The hole (160) may be formed on the outside of the first opening (154). For example, the hole (160) may be formed by cutting out a portion of the first side panel body (151) forming the first opening (154).

[0149] The connecting tip (159) can be formed so that one end (159b) of the connecting tip protrudes from the first side panel body (151) and the other end (159a) of the connecting tip protrudes from the first opening cover (152).

[0150] The connecting tip (159) can be extended to pass through the hole (160). The connecting tip (159) can support the first opening cover (152) by connecting the first opening cover (152) to the first side panel body (151).

[0151] For example, the hole (160) may include a first hole (155) formed by cutting out a portion of the edge of the first side panel (150) forming the first opening (154), and a second hole (156) formed to be recessed from the first hole (155) toward the outside of the first opening (154).

[0152] For example, the diameter of the first hole (155) may be formed smaller than the diameter of the second hole (156). The connecting tip (159) may be extended to pass through the first hole (155) and the second hole (156).

[0153] In order for a user to access the piping space (S) from the outside of the distribution unit (100) through the first opening (154), the first opening cover (152) needs to be removed. To this end, the user can insert a cutting tool or the like into the second hole (156) to cut the connecting tip (159).

[0154] For example, the diameter (D2) of the second hole (156) may include a diameter into which a part of a cutting part, such as a cutting tool, can be inserted to cut the connecting tip (159).

[0155] The first side panel (150) may include a pair of recessed portions (158a, 158b) forming a second hole (156). For example, the distance (D4) between the pair of recessed portions (158a, 158b) may include a distance such that a part of a cutting tool or the like can be inserted therein.

[0156] The user can cut the connecting tip (159) by inserting a portion of the cutting section of the cutting tool into the second hole (156). After cutting the connecting tip (159) and removing the first opening cover (152), the user can access the pipe space (S) through the first opening (154).

[0157] The first side panel (150) may form a first hole (155) and include a pair of protrusions (157a, 157b) that protrude so as to face each other.

[0158] A pair of recessed portions (158a, 158b) can be formed to be connected to a pair of protrusions (157a, 157b).

[0159] For example, each protruding end of a pair of protrusions (157a, 157b) may include a round shape.

[0160] When the connecting tip (159) is cut, a portion of the connecting tip (159) extending from the first side panel body (151) may be positioned on the second hole (156), and the cut end of the connecting tip (159) facing the first opening (154) may have a sharp shape.

[0161] At this time, in order to prevent a part of the user's body passing through the first opening (154) from being damaged by the cut end of the above-mentioned connecting tip, the distance (D3) between the pair of protrusions (157a, 157b) may be formed to be shorter than a part of the user's body. Accordingly, it is possible to prevent a part of the user's body from being inserted into the second hole (156) through the pair of protrusions (157a, 157b). For example, the part of the user's body may include a finger.

[0162] In addition, since each end of the pair of protrusions (157a, 157b) includes a round shape, it is possible to prevent the user's body from being damaged by contact with the pair of protrusions.

[0163] The hole (160) may include a plurality of holes (160) arranged along the edge of the first side panel (150) forming the first opening (154).

[0164] The connecting tip (159) may include a plurality of connecting tips (159) arranged to pass through each of the plurality of holes (160). The plurality of connecting tips (159) may be arranged along the edge of the first opening cover (152). The plurality of connecting tips (159) may be formed at positions corresponding to the plurality of holes (160).

[0165] In the above, the first opening cover (152) is shown and described as being integrally formed with the first side panel body (151) by a connecting tip (159), but this is merely an example, and the first opening cover (152) may include various structures that cover the first opening (154), such as being configured to open and close the first opening (154) through a hinge or the like.

[0166] FIG. 9 is a drawing showing a side panel with the opening cover removed in a heat pump according to one embodiment of the present disclosure.

[0167] FIG. 10 is a drawing showing a portion of a distribution unit having a side panel with an opening cover removed in a heat pump according to one embodiment of the present disclosure.

[0168] FIG. 11 is a top view of a distribution unit in a heat pump according to one embodiment of the present disclosure.

[0169] Referring to FIGS. 9 to 11, a user can remove the opening cover (122, 152) and access the piping space (S) from the outside of the distribution unit (100).

[0170] When the distribution unit (100) is installed indoors, the distribution unit may be installed so that the rear panel (112) is adjacent to the indoor wall (W). In addition, when the ceiling height is low, the user's access to the piping space (S) through the upper space of the distribution unit (100) may be restricted.

[0171] At this time, the user can easily access the pipe space (S) through the opening (124, 154) by removing the opening cover (122, 152), so that the water pipe (P) extending from the pipe space (S) can be effectively maintained and managed (M1, M2).

[0172] For example, the second cover (140) may include a plurality of openings (144a, 144b, 145a, 145b, 146a, 146b, 147a, 147b) arranged in the left-right direction so that the water pipes (P) may pass through. The water pipes (P) may extend from the inside to the outside of the distribution unit (100) through the plurality of openings (144a, 144b, 145a, 145b, 146a, 146b, 147a, 147b).

[0173] For example, the plurality of through holes (144a, 144b, 145a, 145b, 146a, 146b, 147a, 147b) may include a first recovery pipe through hole (160) (145a) and a first supply pipe through hole (160) (145b).

[0174] For example, the plurality of through holes (144a, 144b, 145a, 145b, 146a, 146b, 147a, 147b) may include a second recovery pipe through hole (160) (146a) and a second supply pipe through hole (160) (146b).

[0175] For example, the plurality of through holes (144a, 144b, 145a, 145b, 146a, 146b, 147a, 147b) may include a third recovery pipe through hole (160) (147a) and a third supply pipe through hole (160) (147b).

[0176] A plurality of holes (144a, 144b, 145a, 145b, 146a, 146b, 147a, 147b) arranged in the left-right direction (+-Y direction) can be arranged to form a plurality of rows (ROW) along the front-back direction (+-X direction).

[0177] For example, some of the plurality of holes (144a, 144b, 145a, 145b, 146a, 146b, 147a, 147b) arranged left-right may be arranged at the rear to form a first row (R1). For example, some of the plurality of holes (144a, 144b, 145a, 145b, 146a, 146b, 147a, 147b) arranged left-right may be arranged at the front of the first row (R1) to form a second row (R2). Among the plurality of openings (144a, 144b, 145a, 145b, 146a, 146b, 147a, 147b) arranged in the left-right direction, the remaining portions may be arranged in front of the second row (R2) to form a third row (R3).

[0178] For example, the distance between the first row (R1) and the third row (R3) formed by the plurality of openings (144a, 144b, 145a, 145b, 146a, 146b, 147a, 147b) may be set to correspond to the diameter of the openings in the front-back direction. Accordingly, the user can effectively observe and maintain the water pipes (P) connected to the plurality of openings (144a, 144b, 145a, 145b, 146a, 146b, 147a, 147b) through the openings.
