[0041] The embodiments will be described in detail below with reference to the accompanying drawings.

[0042] Figure 1 This is a schematic diagram illustrating a heat pump according to an embodiment of the present disclosure.

[0043] Reference Figure 1As an example, heat pump 1 may include an outdoor unit 200, which includes a compressor, an expansion valve, and a heat exchanger. Heat pump 1 may also include an indoor unit 600 connected to the outdoor unit 200 via a refrigerant pipe 60.

[0044] In the outdoor unit 200, refrigerant, heated by passing through a compressor, expansion valve, and heat exchanger, is supplied for flow. As an example, the outdoor unit 200 can be provided to be located outdoors and exchange heat with outdoor air.

[0045] As an example, outdoor unit 200 can perform heat exchange between the refrigerant and outdoor air by utilizing the phase change of the refrigerant (e.g., evaporation or condensation). For example, outdoor unit 200 can absorb heat from the outdoor air into the refrigerant by utilizing the evaporation of the refrigerant. Alternatively, outdoor unit 200 can also release heat from the refrigerant to the outdoor air by utilizing the condensation of the refrigerant.

[0046] exist Figure 1 The image shows a single outdoor unit, but the number of outdoor units is not limited to this. Figure 1 The quantities shown are as described. For example, a heat pump may include multiple outdoor units 200.

[0047] Refrigerant can flow between outdoor unit 200 and indoor unit 600 through refrigerant pipe 60. Refrigerant pipe 60 may include: refrigerant supply pipe 61, provided for supplying refrigerant from outdoor unit 200 to indoor unit 600; and refrigerant recovery pipe 62, provided for recovering refrigerant from indoor unit 600 to outdoor unit 200.

[0048] For example, refrigerant heated in outdoor unit 200 can flow to indoor unit 600 through refrigerant supply pipe 61. Thereafter, the refrigerant can be cooled by exchanging heat with indoor air through a heat exchanger provided in indoor unit 600. The refrigerant that has completed heat exchange with indoor air can be recovered back to outdoor unit 200 along refrigerant recovery pipe 62.

[0049] The refrigerant supply line 61 may be equipped with an indoor unit valve 620. The indoor unit valve 620 may be openable and closeable, and may control the flow of refrigerant flowing in the refrigerant supply line 61. For example, when the indoor unit 600 is operating and refrigerant needs to be supplied to the indoor unit 600, the indoor unit valve 620 may be opened, and refrigerant may flow from the outdoor unit 200 to the indoor unit 600.

[0050] Subsequently, when the operation of the indoor unit 600 stops, the indoor unit valve 620 can be closed to prevent refrigerant from being supplied from the outdoor unit 200 to the indoor unit 600.

[0051] The heat pump 1 may include a distribution unit 100 connected to the outdoor unit 200 via a water pipe P. As will be described below, the distribution unit 100 may be provided to distribute heated water to heating units 300, 400 and 500, which heat the locations requiring heating.

[0052] For example, heated water can be provided to be heated in outdoor unit 200. For example, the heated water can be heated by exchanging heat with refrigerant heated by a heat exchanger in outdoor unit 200.

[0053] The above description is merely one example of various methods for heating water, and it should be understood that water can be heated by a separate heating device installed indoors. The following description, using an outdoor unit 200, will serve as an example of a method for heating water.

[0054] Water pipe P is provided to connect outdoor unit 200 and distribution unit 100 to each other, and may include heating water pipe 10 through which heated water flows.

[0055] The heating water pipe 10 may include: a heating water supply pipe 11, provided for supplying heated water from the outdoor unit 200 to the distribution unit 100; and a heating water recovery pipe 12, provided for recovering heated water from the distribution unit 100 back to the outdoor unit 200. For example, the heating water supply pipe 11 and the heating water recovery pipe 12 may be connected to the distribution unit 100 via the upper side of the housing 110 that forms the exterior of the distribution unit 100. Details will be described below.

[0056] For example, the distribution unit 100 can be located in the indoor space O. Therefore, the heated water supply pipe 11 and the heated water recovery pipe 12 can be provided to connect the outdoor unit 200 installed outdoors to the distribution unit 100 installed indoors. In other words, a portion of the heated water supply pipe 11 and the heated water recovery pipe 12 can be configured to extend to the outdoor space, and another portion can be configured to extend to the indoor space O.

[0057] For example, heating units 300, 400, and 500 can be provided to supply heat energy to locations requiring heating by utilizing heated water. Alternatively, heating units 300, 400, and 500 can be provided to directly supply heated water to locations requiring hot water.

[0058] Heating units 300, 400, and 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.

[0059] The hot water supply unit 300 can be provided to directly supply heated water to the user upon request.

[0060] The water pipe P may include a first water pipe 30, which connects the distribution unit 100 and the first heating unit 300 to each other, and heated water can flow through the first water pipe 30. For example, the first supply pipe 31 and the first recovery pipe 32 may be connected to the distribution unit 100 through the upper side of the housing 110 that forms the exterior of the distribution unit 100. Details will be described below.

[0061] The first water pipe 30 may include a first supply pipe 31 and a first recovery pipe 32. The first supply pipe 31 is provided to supply heated water from the distribution unit 100 to the first heating unit 300, and the first recovery pipe 32 is provided to recover heated water from the first heating unit 300 back to the distribution unit 100.

[0062] For example, the first supply pipe 31 may be provided with a first heating valve 310, which is configured to open and close the first supply pipe 31 upon request from a user.

[0063] When the first heating valve 310 opens the first supply pipe 31, heated water can be discharged from the first heating unit 300. When the first heating valve 310 closes the first supply pipe 31, heated water may not be discharged from the first heating unit 300.

[0064] Heating units 300, 400, and 500 may include a second heating unit 400. For example, the second heating unit 400 may be installed indoors.

[0065] For example, the second heating unit 400 may include means provided for heating the indoor space O by exchanging heat from water with indoor air. For example, the second heating unit 400 may include a radiator 410 provided for exchanging heat with indoor air.

[0066] The water pipe P may include a second water pipe 40, which is provided to connect the dispensing unit 100 and the second heating unit 400 to each other, and through which heated water can flow. For example, a second supply pipe 41 and a second recovery pipe 42 may be connected to the dispensing unit 100 through the upper side of the housing 110 that forms the exterior of the dispensing unit 100. Details will be described below.

[0067] The second water pipe 40 may include a second supply pipe 41 and a second recovery pipe 42. The second supply pipe 41 is provided to supply heated water from the distribution unit 100 to the second heating unit 400, and the second recovery pipe 42 is provided to recover heated water from the second heating unit 400 back to the distribution unit 100.

[0068] For example, the second heating unit 400 may include a second heating valve 420, which is operable to open and close the second supply pipe 41 according to a user's request. When the second heating valve 420 opens the second supply pipe 41, heated water can be discharged from the second heating unit 400. When the second heating valve 420 closes the second supply pipe 41, heated water may not be discharged from the second heating unit 400.

[0069] The second heating unit 400 may include a second heating unit controller 430, which is configured to control the operation of the second heating valve 420 and the operation of the radiator 410.

[0070] The user can control the second heating unit controller 430, thereby controlling the operation of the second heating valve 420 and the radiator 410.

[0071] Heating units 300, 400, and 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.

[0072] For example, the third heating unit 500 can be configured to heat the floor of the space in which the underfloor heater 510 is installed by heating the water. That is, the underfloor heater 510 can be installed through the floor in which the third heating unit 500 is installed.

[0073] The water pipe P may include a third water pipe 50, which is provided to connect the distribution unit 100 and the third heating unit 500 to each other, and heated water can flow through the third water pipe 50.

[0074] For example, the third supply pipe 51 and the third recovery pipe 52 can be connected to the dispensing unit 100 via the upper side of the housing 110 that forms the exterior of the dispensing unit 100. Details will be described below.

[0075] The third water pipe 50 may include a third supply pipe 51 and a third recovery pipe 52. The third supply pipe 51 is provided to supply heated water from the distribution unit 100 to the third heating unit 500, and the third recovery pipe 52 is provided to recover heated water from the third heating unit 500 back to the distribution unit 100.

[0076] For example, the third heating unit 500 may include a third heating valve 520, which is operable to open and close the third supply pipe 51 according to a user's request.

[0077] When the third heating valve 520 opens the third supply pipe 51, heated water can be discharged from the third heating unit 500. When the third heating valve 520 closes the third supply pipe 51, heated water may not be discharged from the third heating unit 500.

[0078] The third heating unit 500 may include a third heating unit controller 530, which is provided to control the operation of the third heating valve 520 and the underfloor heater 510. A user can control the third heating unit controller 530, thereby controlling the operation of the third heating valve 520 and the underfloor heater 510.

[0079] The types of heating units and methods of supplying heat to the heating locations described above are merely examples, and it should be understood that heating units can be installed and operated in various locations where heating and hot water supply are required.

[0080] Figure 2 This is a diagram illustrating a heat pump according to an embodiment of the present disclosure, wherein the distribution unit and water pipes are separated.

[0081] Figure 3 This shows different views of embodiments according to this disclosure. Figure 2 The diagram shows the distribution unit and water pipes.

[0082] Reference Figure 2 and Figure 3 The distribution unit 100 may include a housing 110 forming the exterior. The machine room 118 (see...) Figure 4 It can be formed inside the housing 110.

[0083] The housing 110 may include a front panel 111 forming a front surface (+X direction), side panels 120 and 150 forming two side surfaces (+Y direction and -Y direction), and a rear panel 112 forming a rear surface (-X direction).

[0084] The front panel 111 and the side panels 120 and 150 can be formed to have corresponding heights H1. The heights H1-H2 of the rear panel 112 can be formed to be lower than the heights H1 of the front panel 111 and the side panels 120 and 150.

[0085] An operating section 101, oriented forward (+X direction), can be provided on the front panel 111. The operating section 101 can be provided through a front panel opening 102 formed in the front panel 111 (see...). Figure 4 It is connected to the indoor space O.

[0086] For example, a user can control the operation of the distribution unit 100 through the operation section 101. 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 operation section 101 may be provided to display information about the distribution unit 100.

[0087] Side panels 120 and 150 may include a first side panel 150 forming the right surface (-Y direction) of the dispensing unit 100 and a second side panel 120 forming the left surface (+Y direction) of the dispensing unit 100.

[0088] The first side panel 150 may include a first side panel body 151 that forms its appearance. The first side panel 150 may include a first upper bent surface 151a formed by bending to the left (in the +Y direction) through the upper edge of the first side panel body 151.

[0089] The first side panel 150 may include a first side-end bending surface 151b, which is formed by bending the side edge located at the rear (-X direction) of the first side panel body 151 to the left.

[0090] Due to the first upper bending surface 151a and the first side bending surface 151b, the first side panel body 151 has a bent shape at its ends instead of a general flat shape, thereby ensuring rigidity compared to a flat shape and preventing the first side panel body 151 from deforming due to external forces.

[0091] The first side panel 150 may include a first opening cover 152 located on the rear (-X direction) upper (+Z direction) side of the first side panel body 151.

[0092] The first opening cover 152 may be configured to cover the first opening 154 (described below), which is formed through the first side panel body 151. Details will be described below.

[0093] The second side panel 120 may include a second side panel body 121 that forms the appearance. The second side panel 120 may include a second upper bent surface 121a formed by bending to the right (in the +Y direction) through the upper edge of the second side panel body 121.

[0094] The second side panel 120 may include a second side end bending surface 121b formed by bending to the right through the rear edge of the second side panel body 121.

[0095] Due to the second upper bending surface 121a and the second side bending surface 121b, the second side panel body 121 has a bent shape at its ends, rather than a typical flat plate shape, thereby ensuring rigidity compared to a flat plate shape and preventing the second side panel body 121 from deforming due to external forces.

[0096] The second side panel 120 may include a second opening cover 122 located on the rear upper side of the second side panel body 121. The second opening cover 122 may be configured to cover a second opening 124 formed through the second side panel body 121 (which will be described below).

[0097] The dispensing unit 100 can be disposed in an interior space O such that the rear panel 112 faces the interior wall surface W. For example, the dispensing unit 100 can be provided such that the rear panel 112 is adjacent to the wall surface W. For example, the dispensing unit 100 can be provided such that the rear panel 112 is in contact with the wall surface W.

[0098] The dispensing unit 100 may include a first cover 130 and a second cover 140. The first cover 130 is mounted on the upper side of the housing 110 and covers a portion of the machine chamber 118. The second cover 140 is connected to the first cover 130 to cover another portion of the machine chamber 118.

[0099] For example, the first cover 130 may be provided to cover the upper (+Z direction) front (+X direction) side of the machinery room 118.

[0100] The first cover 130 may include a cover portion 131 covering the machine room 118 and an extension portion 132 bending downward (in the -Z direction) from the cover portion 131.

[0101] The cover portion 131 can be supported by being attached to the front panel 111 at one end 131a. The cover portion 131 may include the shape of a plate and may be provided to cover the upper front side of the machine compartment 118.

[0102] The cover portion 131 may extend in the left-right direction (+Y direction and -Y direction) to be adjacent to a pair of side panels 120 and 150. For example, the cover portion 131 may be positioned adjacent to the upper edge of each of the pair of side panels 120 and 150.

[0103] The length of the cover portion 131 in the front-to-back direction can be set to be shorter than the lengths of the side panels 120 and 150 in the front-to-back direction. The front end of the cover portion 131 can be provided to be adjacent to the front ends of the side panels 120 and 150.

[0104] The extension 132 may be formed to bend downward from the other end 131b of the cover portion 131. For example, the other end 131b of the cover portion 131 may be the rearward end of the cover portion 131. The upper end 132b of the extension 132 may engage the other end 131b of the cover portion 131. The extension 132 may also have a generally plate-like shape.

[0105] The extension 132 may extend to the left and right to be adjacent to a pair of side panels 120 and 150. The extension 132 may be formed as part of the cover portion 131, but it should be understood that the cover portion 131 and the extension 132 may be formed as separate components that are separable from each other.

[0106] Since the extension 132 extends downward from the rear end of the cover portion 131, the extension 132 can extend toward the machine room 118. Therefore, the extension 132 can extend such that its lower end faces the machine room 118.

[0107] For example, the second cover 140 can form a component with the first cover 130.

[0108] The second cover 140 may be configured to extend rearward (in the -X direction). The other rearward end 141a of the second cover may be attached to the rear panel 112 of the housing 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.

[0109] Since the second cover 140 is positioned below the first cover 130, the second cover 140 can be positioned between the upper and lower edges of the side panels 120 and 150. For example, the height of the second cover 140 can correspond to the height H1 of the housing 110 minus the length (+H2) of the extension portion 132 of the first cover 130, thus obtaining the height H1-H2.

[0110] The second cover 140 may include a second cover body 141 forming its appearance. The second cover 140 may be connected to a water pipe P. More specifically, the second cover 140 may include a plurality of through holes 144a, 144b, 145a, 145b, 146a, 146b, 147a and 147b formed to allow the water pipe P to pass through it.

[0111] Multiple through holes 144a, 144b, 145a, 145b, 146a, 146b, 147a, and 147b can be formed to pass through the second cover body 141. The dispensing 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 multiple brackets 13 installed in each of the multiple through holes 144a, 144b, 145a, 145b, 146a, 146b, 147a, and 147b.

[0112] A portion of the water pipe P may be provided in the machine room 118. Another portion of the water pipe P may extend through the second cover 140 to the outside of the machine room 118 via the aforementioned plurality of through holes 144a, 144b, 145a, 145b, 146a, 146b, 147a and 147b.

[0113] The water pipe P passing through the second cover 140 can extend upwards and then extend in the direction intersecting the vertical direction (+X direction and -X direction).

[0114] The heat pump 1 may include a piping space S through which a water pipe P extends through the second cover 140.

[0115] More specifically, the piping space S can be defined as the space surrounded by the 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 may include a generally cuboid shape.

[0116] The piping space S can be formed on the upper rear side of the distribution unit 100. The piping space S can be formed to open upward (in the +Z direction) and backward (in the -X direction). For example, when the rear panel 112 of the distribution unit 100 is provided to be adjacent to the wall surface W of the room, the rear part of the piping space S can be covered by the wall surface W.

[0117] The length of the piping space S in the vertical direction can approximately correspond to the length H2 of the extension portion 132 in the vertical direction. Therefore, the water pipe P passing through the second cover 140 can extend the length of the piping space S in the vertical direction and then pass through the cover portion 131 of the first cover 130.

[0118] Therefore, even when the distribution unit 100 is installed in an indoor space with a low ceiling height, the water pipe P can ensure an extendable distance corresponding to the length of the piping space S in the vertical direction.

[0119] The portions of side panels 120 and 150 that form the piping space S may include openings communicating with the piping space S (see...). Figure 10 Users can easily access the water pipe P extending in the piping space S through openings 124 and 154, see [link / reference]. Figure 10 For maintenance and repair of water pipe P (see M1 and M2). Openings 124 and 154 can be covered by opening covers 122 and 152. Details are described below.

[0120] Figure 4 This is a diagram illustrating a heat pump according to an embodiment of the present disclosure, wherein the distribution unit and water pipes are separated, and the distribution unit is disassembled.

[0121] Figure 5 This is a diagram showing a distribution unit separate from the heat pump according to an embodiment of the present disclosure, wherein components of the distribution unit are disassembled.

[0122] Reference Figure 4 and Figure 5 The housing 110 may include a lower panel 114. The lower panel may form the lower surface of the housing 110.

[0123] The distribution unit 100 may include a mechanical chamber 118 formed inside the housing 110.

[0124] For example, the machine room 118 can be defined as a space formed by a front panel 111, a pair of side panels 120 and 150, a lower panel 114, a rear panel 112, a first cover 130 and a second cover 140.

[0125] The distribution unit 100 may include a water tank 115 disposed in the machine room 118. For example, a water pipe P may be connected to the water tank 115. For example, the water tank 115 may hold additional hot water.

[0126] Water pipe P may include water tank connection pipes 115a and 115b connected to water tank 115. Heated water can be introduced into water tank 115 from the outside through water tank connection pipes 115a and 115b. Heated water can be discharged from water tank 115 to the outside through water tank connection pipes 115a and 115b.

[0127] The distribution unit 100 may include a filter device 117 configured to communicate with the water pipe P. The filter device 117 may be configured to filter out foreign matter contained in the heated water that has passed through the filter device 117.

[0128] For example, water pipe P may include filter device connection pipes 117a and 117b that communicate with filter device 117. For example, heated water flowing from the outside to distribution unit 100 through water pipe P may be provided to pass through filter device 117.

[0129] The distribution unit 100 may include an auxiliary heater 116 configured to communicate with a water pipe P. The water pipe P may include auxiliary heater connecting pipes 116a and 116b communicating with the auxiliary heater 116. The auxiliary heater 116 may be configured to heat water passing through it.

[0130] Therefore, even when the temperature of the heating water flowing from the outside to the distribution unit 100 decreases, the heating water is allowed to pass through the auxiliary heater to maintain the temperature required for the heating position.

[0131] Heating units 300, 400, and 500 may include an electrical component 103 in which an operating component 101 is mounted. The electrical component 103 may include a printed circuit board and various electronic components mounted on the printed circuit board.

[0132] Electrical components 103 can be provided to connect the operating components 101 to the front panel opening 102. Thus, the user can control the operation of the distribution unit 100 by operating the operating components 101.

[0133] For example, the electrical part 103 can be configured such that the height of the upper end of the electrical part 103 in the vertical direction (+Z direction and -Z direction) is higher than the height of the second cover 140. In other words, the electrical part 103 can be configured such that the height of the upper end of the electrical part 103 is higher than the height of the second cover body 141 is positioned.

[0134] For example, the electrical part 103 can be positioned such that the height of the upper end of the electrical part 103 in the vertical direction (+Z direction and -Z direction) is lower than the height of the cover portion 131 of the first cover 130. For example, the electrical part 103 can be positioned such that the position of the upper end of the electrical part 103 in the vertical direction (+Z direction and -Z direction) is between the position of the cover portion 131 in the vertical direction and the position of the second cover body 141 in the vertical direction.

[0135] For example, the second cover 140 may be a separate construction that is detachably attached to the first cover 130. For example, the second cover 140 may be attached to an extension 132 of the first cover 130. More specifically, the forward-facing (+X direction) end 141b of the second cover may be configured to be attached to the downward-facing (-Z direction) lower end 132a of the extension 132 of the first cover 130.

[0136] The second cover 140 may include second cover support portions 142 extending upward from the left and right ends of the second cover body 141. For example, the second cover support portion 142 may include a generally quadrilateral shape, but is not limited thereto.

[0137] The second cover support portion 142 can be provided to support the second cover 140 by being connected to the side panels 120 and 150. For example, the second cover support portion 142 can be provided to be connected to the first side panel 150 and the second side panel 120, respectively.

[0138] The second cover support portion 142 may include a support portion opening 143.

[0139] The support opening 143 can be formed to pass through the second cover support 142. The support opening 143 can communicate with the piping space S.

[0140] The support opening 143 can communicate with the openings in the side panels 120 and 150 described below. Therefore, the interior space can communicate with the piping space S through the openings and the support opening 143.

[0141] Figure 6 This is a diagram showing the side panel of the distribution unit in a heat pump according to an embodiment of the present disclosure.

[0142] Figure 7 It is based on the embodiments of this disclosure. Figure 6 An enlarged view of a portion of the side panel shown.

[0143] Figure 8 It is based on the embodiments of this disclosure. Figure 7 A magnified view of a portion of it.

[0144] The following description pertains to the first side panel 150. It should be understood that the following description of the side panel can also be applied to the second side panel 120.

[0145] Reference Figures 6 to 8 The first side panel 150 may include: a first opening 154 formed through the first side panel body 151; a first opening cover 152 covering the first opening 154; and a hole 160 formed outside the first opening 154 and passing through the first side panel body 151 to connect to the opening. For example, the first opening cover 152 may be formed as a component with the first side panel body 151.

[0146] The first opening 154 can be formed as a portion of the piping space S that passes through the main body 151 of the first side panel.

[0147] For example, a first opening 154 may be formed on the upper rear side of the first side panel body 151. The first opening 154 may include, but is not limited to, a generally quadrilateral shape.

[0148] The first opening cover 152 can be configured to cover a portion of the first opening 154. The first opening cover 152 can be supported on the first side panel body 151 via a connection tip 159 connected to the first side panel 150.

[0149] The hole 160 may be formed on the outside of the first opening 154. For example, the hole 160 may be formed by cutting off a portion of the first side panel body 151 that forms the first opening 154.

[0150] The connecting end 159 can be configured such that one end 159b of the connecting end protrudes from the first side panel body 151, and the other end 159a of the connecting end protrudes from the first opening cover 152.

[0151] The connecting end 159 can extend through the hole 160. The connecting end 159 can connect the first opening cover 152 to the first side panel body 151 so that the first opening cover 152 can be supported.

[0152] For example, hole 160 may include a first hole portion 155 and a second hole portion 156, the first hole portion 155 being formed by cutting a portion of the edge of the first side panel 150 that forms the first opening 154, and the second hole portion 156 being formed to be recessed from the first hole portion 155 in the outward direction of the first opening 154.

[0153] For example, the diameter of the first hole portion 155 can be formed to be smaller than the diameter of the second hole portion 156. The connecting end 159 can extend through the first hole portion 155 and the second hole portion 156.

[0154] To allow the user to access the piping space S from outside the distribution unit 100 through the first opening 154, the first opening cover 152 needs to be removed. For this purpose, the user can insert a cutting tool or similar device into the second hole portion 156 to cut the connection end 159.

[0155] For example, the diameter D2 of the second hole portion 156 may include a portion of the diameter that allows a cutting tool or the like to be inserted to cut the diameter of the connecting end 159.

[0156] The first side panel 150 may include a pair of recessed portions 158a and 158b forming the second hole portion 156. For example, the distance D4 between the pair of recessed portions 158a and 158b may include a separation distance that allows a portion of a cutting tool or the like to be inserted.

[0157] The user can insert a portion of the cutting part of the cutting tool into the second hole portion 156 to cut the connection end 159. The user can cut the connection end 159 to remove the first opening cap 152 and then enter the piping space S through the first opening 154.

[0158] The first side panel 150 may include a pair of protrusions 157a and 157b that protrude to face each other while forming the first hole portion 155.

[0159] A pair of recessed portions 158a and 158b can be formed to connect to a pair of protruding portions 157a and 157b.

[0160] For example, each of the protruding ends of a pair of protrusions 157a and 157b may include an arc shape.

[0161] With the connecting end 159 cut, a portion of the connecting end 159 extending from the first side panel body 151 can be positioned on the second hole portion 156, and the cut end of the connecting end 159 facing the first opening 154 can have a sharp shape.

[0162] In this configuration, to prevent damage to a portion of the user's body that has already passed through the first opening 154 from the cutting end of the connecting end, the distance D3 between the pair of protrusions 157a and 157b can be made shorter than the portion of the user's body. Therefore, it is possible to prevent a portion of the user's body from being inserted into the second hole portion 156 through the area between the pair of protrusions 157a and 157b. For example, a portion of the user's body may include a finger.

[0163] In addition, since each end of the pair of protrusions 157a and 157b includes an arc shape, it can prevent the user's body from being injured due to contact with the pair of protrusions.

[0164] The hole 160 may include a plurality of holes 160 provided along the edge of the first side panel 150 forming the first opening 154.

[0165] The connection end 159 may include a plurality of connection ends 159 provided to pass through each of the plurality of holes 160. The plurality of connection ends 159 may be provided along the edge of the first opening cover 152. The plurality of connection ends 159 may each be formed at a position corresponding to the plurality of holes 160.

[0166] In the foregoing, the first opening cover 152 is described and shown as forming a component with the first side panel body 151 via the connecting end 159, but this is only an example, and the first opening cover 152 may include various structures such as opening and closing the first opening 154 to cover the first opening 154 via a hinge or the like.

[0167] Figure 9 This is a diagram showing the side panel of a heat pump according to an embodiment of the present disclosure, wherein the opening cover has been removed.

[0168] Figure 10 This is a diagram illustrating a heat pump according to an embodiment of the present disclosure, showing a portion of the distribution unit, wherein the opening cover is removed from the side panel.

[0169] Figure 11 This is a top view of the distribution unit of a heat pump according to an embodiment of the present disclosure.

[0170] Reference Figures 9 to 11 Users can remove opening covers 122 and 152 and access the piping space S from the outside of the distribution unit 100.

[0171] When the distribution unit 100 is installed indoors, it can be installed such that the rear panel 112 is adjacent to the wall surface W of the indoor space. Additionally, when the ceiling height is low, it may restrict user access to the piping space S through the upper space of the distribution unit 100.

[0172] In this case, the user can easily access the piping space S through openings 124 and 154 by removing opening covers 122 and 152, thereby effectively maintaining and managing the water pipe P extending in the piping space S (see M1 and M2).

[0173] For example, the second cover 140 may include a plurality of through holes 144a, 144b, 145a, 145b, 146a, 146b, 147a, and 147b arranged in the left-right direction, allowing the water pipe P to pass through it. The water pipe P can extend from the interior to the exterior of the dispensing unit 100 through the plurality of through holes 144a, 144b, 145a, 145b, 146a, 146b, 147a, and 147b.

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

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

[0176] For example, the plurality of through holes 144a, 144b, 145a, 145b, 146a, 146b, 147a and 147b may include a third recovery pipe through hole 147a and a third supply pipe through hole 147b.

[0177] Multiple through holes 144a, 144b, 145a, 145b, 146a, 146b, 147a and 147b arranged in the left-right direction (+Y direction and -Y direction) can be arranged to form multiple rows along the front-back direction (+X direction and -X direction).

[0178] For example, some of the multiple through holes 144a, 144b, 145a, 145b, 146a, 146b, 147a, and 147b arranged in the left-right direction can be provided at the rear to form a first row R1. For example, some of the multiple through holes 144a, 144b, 145a, 145b, 146a, 146b, 147a, and 147b arranged in the left-right direction can be provided at the front of the first row R1 to form a second row R2. Some of the remaining holes 144a, 144b, 145a, 145b, 146a, 146b, 147a, and 147b arranged in the left-right direction can be provided at the front of the second row R2 to form a third row R3.

[0179] For example, the distance between the first row R1 and the third row R3 formed by multiple holes 144a, 144b, 145a, 145b, 146a, 146b, 147a, and 147b can be provided as the diameter corresponding to the opening in the front-back direction. Therefore, the user can effectively observe and maintain the water pipe P connected to the multiple through holes 144a, 144b, 145a, 145b, 146a, 146b, 147a, and 147b through the openings.
