Description

heat source machine

[0001] An embodiment of the present invention relates to a heat source machine in which an air heat exchanger is disposed on top of a machine room-side housing that houses a compressor and the like.

[0002] For example, the heat source machine disclosed in Patent Document 1 has a configuration in which an air heat exchanger that exchanges heat with air is disposed on top of a machine room-side housing that houses a compressor and the like.

[0003] Patent No. 6657399

[0004] The conventional heat source machine described above includes a refrigerant pipe that forms a refrigeration cycle together with a compressor and the like in the machine room housing and an air heat exchanger in the upper part of the machine room housing. The refrigerant pipe passes through a through-hole provided between the machine room housing and the air heat exchanger. In this configuration, there is a concern that water may infiltrate from the upper air heat exchanger into the lower machine room housing through the through-hole. Therefore, in order to prevent water from infiltrating from the air heat exchanger into the machine room housing through the through-hole, it has been considered to provide a waterproof structure surrounding the through-hole.

[0005] However, in some heat source machines, the air heat exchanger is installed at an angle so that it is narrow at the bottom and wide at the top. In heat source machines with such a configuration, even if an attempt is made to install a waterproof structure between the machine room housing and the air heat exchanger, i.e., in the lower part of the air heat exchanger, the lower part of the air heat exchanger is narrower than the upper part, making it difficult to install the waterproof structure and to fix the refrigerant piping.

[0006] Therefore, this embodiment provides a heat source machine that makes it easy to install a structure to prevent liquid from entering the machine room side housing from the air heat exchanger through the through hole provided between the machine room side housing and the air heat exchanger.

[0007] The heat source unit of this embodiment comprises a machine room side housing that houses at least a compressor, an air heat exchanger arranged on top of the machine room side housing, refrigerant piping that forms a refrigeration cycle together with at least the compressor and the air heat exchanger, a through hole that allows the refrigerant piping to pass between the machine room side housing and the air heat exchanger, and a suppression section that suppresses liquid from seeping into the machine room side housing from the air heat exchanger through the through hole, wherein the air heat exchanger is formed by combining a first air heat exchanger forming part and a second air heat exchanger forming part, and the suppression section is formed by combining a first suppression section forming part provided on the first air heat exchanger forming part and a second suppression section forming part provided on the second air heat exchanger forming part, and the refrigerant piping is supported by the suppression section.

[0008] The heat source device according to the present embodiment includes a machine room-side housing that houses at least a compressor, an air heat exchanger arranged on an upper portion of the machine room-side housing, a support portion that supports the air heat exchange portion, refrigerant piping that constitutes a refrigeration cycle together with at least the compressor and the air heat exchanger, a through hole that passes the refrigerant piping between the machine room-side housing and the air heat exchanger, and a suppression portion that suppresses liquid from seeping into the machine room-side housing from the air heat exchanger through the through hole. and a second air heat exchanger forming part, the support part is formed by combining a first support part forming part provided on the first air heat exchanger forming part and a second support part forming part provided on the second air heat exchanger forming part, the suppression part is formed by combining a first suppression part forming part provided on the first support part forming part and a second suppression part forming part provided on the second support part forming part, and the refrigerant piping is supported by the suppression part.

[0010] An embodiment of a heat source machine will be described below with reference to the drawings. The heat source machine 1 illustrated in FIG. 1 is, for example, what is called a "chiller," and in this case, is configured as an air-cooled heat pump chilling unit. The heat source machine 1 is capable of generating hot water for heating a temperature-controlled object (not shown). The heat source machine 1 is also capable of generating cold water for cooling a temperature-controlled object (not shown).

[0011] The heat source machine 1 includes a machine room-side housing 2 as a lower section that constitutes the lower part of the heat source machine 1. The machine room-side housing 2 houses at least a compressor 3. The heat source machine 1 includes multiple compressors 3, in this case two compressors 3. The heat source machine 1 may be configured to include one compressor 3, or may be configured to include three or more compressors 3. The machine room-side housing 2 also houses an expansion valve, a water heat exchanger, an accumulator, a switching valve, etc., which are not shown.

[0012] The heat source machine 1 includes an air heat exchanger 4 as an upper section that constitutes the upper part of the heat source machine 1. In other words, the upper section can be defined as an air heat exchanger-side housing that includes the air heat exchanger 4 and a blower fan 5, which will be described later. The heat source machine 1 includes multiple air heat exchangers 4, in this case two, depending on the number of compressors 3. Note that the heat source machine 1 may be configured to include one air heat exchanger 4 depending on the number of compressors 3, or may be configured to include three or more air heat exchangers 4.

[0013] The air heat exchangers 4 are each disposed at the top of the machine room-side housing 2. A blower fan 5 is provided above each air heat exchanger 4. Each air heat exchanger 4 is configured to be able to exchange heat with air blown by the blower fan 5. As is well known, the air heat exchanger 4 is configured by combining a plurality of fins with refrigerant piping 11. The refrigerant piping 11 will be described in detail later.

[0014] The air heat exchanger 4, together with the compressor 3 housed in the machine room housing 2, and an expansion valve, a water heat exchanger, an accumulator, a switching valve, and the like (not shown), constitute a well-known refrigeration cycle unit. The operation mode of the refrigeration cycle unit can be switched between a heating mode and a cooling mode. The switching of the operation mode of the refrigeration cycle unit can be controlled by using a switching valve to reverse the flow direction of the refrigerant in the refrigerant pipe 11 that constitutes the refrigeration cycle unit.

[0015] When the refrigeration cycle unit is switched to the heating mode, the air heat exchanger 4 operates as a cooler, and the water heat exchanger operating as a heater heats the water as a heat medium, and hot water is supplied to the temperature-controlled object. On the other hand, when the refrigeration cycle unit is switched to the cooling mode, the air heat exchanger 4 operates as a heater, and the water heat exchanger operating as a cooler cools the water as a heat medium, and cold water is supplied to the temperature-controlled object.

[0016] 2, the air heat exchanger 4 is supported from below by a baffle plate 6. The baffle plate 6 is an example of a support portion and is made of, for example, a metal plate. In the heat source unit 1, the baffle plate 6 is disposed between the machine room housing 2 and the air heat exchanger 4. Here, the baffle plate 6 functions as a platform on which the air heat exchanger 4 is placed, and may also function as a drain pan that receives water from the air heat exchanger 4 side.

[0017] 2 and 3 , the baffle plate 6 is formed by combining a first baffle plate forming part 6A and a second baffle plate forming part 6B. The first baffle plate forming part 6A is an example of a first support portion forming part, and the second baffle plate forming part 6B is an example of a second support portion forming part. The upper surface of the first baffle plate forming part 6A is an inclined surface that slopes downward from the second baffle plate forming part 6B side toward the opposite side of the second baffle plate forming part 6B. On the other hand, the upper surface of the second baffle plate forming part 6B is an inclined surface that slopes downward from the first baffle plate forming part 6A side toward the opposite side of the first baffle plate forming part 6A.

[0018] The air heat exchanger 4 is formed by combining a first air heat exchanger forming part 4A and a second air heat exchanger forming part 4B. A first baffle plate forming part 6A is attached to the lower end of the first air heat exchanger forming part 4A. Meanwhile, a second baffle plate forming part 6B is attached to the lower end of the second air heat exchanger forming part 4B.

[0019] As illustrated in Figures 3 and 4, the heat source machine 1 is configured to form the air heat exchanger 4 placed on the baffle plate 6 by combining a first air heat exchanger forming part 4A having a first baffle plate forming part 6A attached to its lower end and a second air heat exchanger forming part 4B having a second baffle plate forming part 6B attached to its lower end.

[0020] In other words, the heat source unit 1 is configured such that the baffle plate 6 is formed by combining a first baffle plate forming part 6A and a second baffle plate forming part 6B, and the air heat exchanger 4 is formed by combining a first air heat exchanger forming part 4A and a second air heat exchanger forming part 4B on the baffle plate 6.

[0021] Here, the first air heat exchanger forming part 4A is placed on the inclined surface of the first baffle plate forming part 6A of the baffle plate 6. On the other hand, the second air heat exchanger forming part 4B is placed on the inclined surface of the second baffle plate forming part 6B of the baffle plate 6. Therefore, as shown in Figure 2, the air heat exchanger 4 is provided on the baffle plate 6 in an inclined state so that the lower side is narrow and the upper side is wide.

[0022] Here, both ends of the first air heat exchanger forming part 4A are bent, thereby forming an air heat exchange chamber inside the first air heat exchanger forming part 4A. Also, both ends of the second air heat exchanger forming part 4B are bent, thereby forming an air heat exchange chamber inside the second air heat exchanger forming part 4B. Both ends of the first air heat exchanger forming part 4A are provided with fixing reinforcement parts 41 that are placed inside the air heat exchange chamber. Also, both ends of the second air heat exchanger forming part 4B are provided with fixing reinforcement parts 41 that are placed inside the air heat exchange chamber.

[0023] The fixing reinforcement part 41 provided on the first air heat exchanger forming part 4A is fixed to the first baffle plate forming part 6A, firmly fixing the first air heat exchanger forming part 4A to the first baffle plate forming part 6A. The fixing reinforcement part 41 provided on the second air heat exchanger forming part 4B is fixed to the second baffle plate forming part 6B, firmly fixing the second air heat exchanger forming part 4B to the second baffle plate forming part 6B.

[0024] The fixing reinforcement portion 41 not only ensures the strength of the air heat exchanger 4 and the baffle plate 6 in the final assembled state, but also ensures the strength against vibrations during transportation and assembly at the component stage of the manufacturing process. The fixing reinforcement portion 41 may be provided with openings to reduce ventilation resistance as long as the strength is not impaired.

[0025] 2, when the first air heat exchanger forming part 4A and the second air heat exchanger forming part 4B are combined, an upper end fixing frame 42 is provided at their upper ends to support the first air heat exchanger forming part 4A and the second air heat exchanger forming part 4B so that they are tilted and upright. A fan motor 5A of the blower fan 5 is fixed near the center of the upper end fixing frame 42.

[0026] With the heat source unit 1 configured in this manner, even if multiple heat source units 1 are arranged adjacently, as illustrated in Fig. 5, for example, it is possible to ensure a space S between the air heat exchangers 4. Therefore, even if multiple heat source units 1 are arranged adjacently, it is possible to prevent air from being difficult to take in into the air heat exchanger 4 of each heat source unit 1. Furthermore, when installing multiple heat source units 1 adjacently, a worker can insert his or her fingers or tools into this space S, or the worker himself or herself can enter the space S to perform work such as fixing the heat source units 1, making it easy to install the heat source units 1.

[0027] 6 , the baffle plate 6 is provided with a through-hole 10 that passes through the baffle plate 6 in the vertical direction. In this case, the through-hole 10 opens in a rectangular shape at the boundary between the first baffle plate forming part 6A and the second baffle plate forming part 6B of the baffle plate 6. This through-hole 10 allows a refrigerant pipe 11 to pass between the machine compartment housing 2 and the air heat exchanger 4. As described above, the refrigerant pipe 11 constitutes a refrigeration cycle together with the compressor 3, the air heat exchanger 4, and an expansion valve, a water heat exchanger, an accumulator, a switching valve, and the like (not shown).

[0028] 7 , the heat source unit 1 includes a waterproof structure 20 that prevents water, an example of a liquid, from seeping through the through-hole 10 from the upper air heat exchanger 4 into the lower machine room housing 2. Examples of water that may seep into the machine room housing 2 from the air heat exchanger 4 side through the through-hole 10 include rainwater that has entered the air heat exchanger 4 from outside the machine, defrosted water generated during defrosting operation of the air heat exchanger 4, and condensed water that forms on the surface of the refrigerant pipe 11. The waterproof structure 20 is an example of a suppression unit and is made of, for example, a metal plate. The waterproof structure 20 includes a main body 21 and a cover member 22.

[0029] 6, the main body 21 is formed by combining a first waterproof structure forming part 21A and a second waterproof structure forming part 21B. The first waterproof structure forming part 21A is an example of a first suppression part forming part, and is provided at the end of the first baffle plate forming part 6A that faces the second baffle plate forming part 6B. On the other hand, the second waterproof structure forming part 21B is an example of a second suppression part forming part, and is provided at the end of the second baffle plate forming part 6B that faces the first baffle plate forming part 6A.

[0030] The first waterproof structure forming part 21A can be defined as being attached to the first air heat exchanger forming part 4A via the first baffle plate forming part 6A, while the second waterproof structure forming part 21B can be defined as being attached to the second air heat exchanger forming part 4B via the second baffle plate forming part 6B.

[0031] The refrigerant pipe 11 is supported by the waterproof structure 20. More specifically, as illustrated in Fig. 6, the main body 21 of the waterproof structure 20 is formed in the shape of a rectangular box with an open top and side surfaces 21Aa, 21Ab, 21Ac, and 21Ba surrounding the through-hole 10. The refrigerant pipe 11 is arranged to pass through the upper sides of the side surfaces 21Ab and 21Ba.

[0032] 7 , the lid member 22 is attached so as to close the open top portion of the main body 21. The lid member 22 is fixed to the top of the main body 21 with, for example, screws or bolts. The lid member 22 is formed in a rectangular plate shape that is larger than the opening area of ​​the open top portion of the main body 21. Therefore, the end of the lid member 22 that closes the open top portion of the main body 21 protrudes outward like a canopy beyond the main body 21.

[0033] The side surfaces 21Aa, 21Ab, and 21Ac constitute a first waterproof structure forming part 21A. The first waterproof structure forming part 21A has an open surface facing the side surface 21Ab. The side surface 21Ba constitutes a second waterproof structure forming part 21B. The second waterproof structure forming part 21B is configured to be able to close the open surface of the first waterproof structure forming part 21A facing the side surface 21Ab.

[0034] The first baffle plate forming part 6A and the second baffle plate forming part 6B are combined to form the baffle plate 6, and the first air heat exchanger forming part 4A and the second air heat exchanger forming part 4B are combined on the baffle plate 6 to form the air heat exchanger 4. As a result, the first waterproof structure forming part 21A and the second waterproof structure forming part 21B are combined around the through hole 10 to form the main body 21 of the waterproof structure 20. A lid member 22 is attached to the open top portion of the main body 21, thereby forming the box-shaped waterproof structure 20 that closes the periphery and above the through hole 10.

[0035] The refrigerant pipes 11 are supported at their horizontally extending portions, not at their vertically extending portions, on the side surfaces of the box-shaped waterproof structure 20. In this case, the refrigerant pipes 11 are supported in a distributed manner on the mutually opposing side surface portions 21Ab and 21Ba of the multiple side surface portions 21Aa, 21Ab, 21Ac, and 21Ba that form the waterproof structure 20. Alternatively, the refrigerant pipes 11 can be defined as being supported in a distributed manner on the side surface portion 21Ab that constitutes the first waterproof structure-forming part 21A and the side surface portion 21Ba that constitutes the second waterproof structure-forming part 21B.

[0036] In this case, side surface portion 21Ab supports one refrigerant pipe 11. Meanwhile, side surface portion 21Ba supports a plurality of refrigerant pipes 11, in this case two refrigerant pipes 11. Each refrigerant pipe 11 is supported on waterproof structure portion 20 by a rubber supporter 30 and a fixing clamp 31.

[0037] The rubber supporter 30 is an example of a first support member and is made of an elastically deformable material such as rubber. The rubber supporter 30 is fitted into the side surface portion 21Ab and the side surface portion 21Ba, respectively, and constitutes a part of the side surface portion 21Ab and the side surface portion 21Ba.

[0038] On the other hand, the fixing clamp 31 is an example of a second support member and is made of a non-elastically deformable material such as metal. The fixing clamp 31 is arranged to form a pair with the rubber supporter 30 inside the waterproof structure 20. The waterproof structure 20 also includes a sealing member 33 between the first waterproof structure forming part 21A and the second waterproof structure forming part 21B.

[0039] The heat source unit 1 described above includes a through-hole 10 between the machine room housing 2 and the air heat exchanger 4, through which the refrigerant piping 11 passes, and a waterproof structure 20 that prevents water, an example of a liquid, from penetrating from the air heat exchanger 4 into the machine room housing 2 through the through-hole 10. The air heat exchanger 4 is formed by combining a first air heat exchanger forming part 4A and a second air heat exchanger forming part 4B. The waterproof structure 20 is formed by combining a first waterproof structure forming part 21A provided on the first air heat exchanger forming part 4A side and a second waterproof structure forming part 21B provided on the second air heat exchanger forming part 4B side. The refrigerant piping 11 is supported by the waterproof structure 20.

[0040] Here, the heat source unit 1 of the present disclosure is configured such that the air heat exchanger 4 is inclined so that it is narrow at the bottom and wide at the top, and therefore the lower portion of the air heat exchanger 4 is narrow when the air heat exchanger 4 is assembled. Therefore, it is difficult to provide a waterproof structure 20 on the lower portion of the air heat exchanger 4 after the air heat exchanger 4 is assembled.

[0041] However, according to the heat source unit 1 of the present disclosure, the first air heat exchanger forming part 4A and the second air heat exchanger forming part 4B are combined to form the air heat exchanger 4, and the first waterproof structure forming part 21A and the second waterproof structure forming part 21B are combined to form the waterproof structure 20.

[0042] According to this configuration example, in a heat source unit 1 in which the lower side of the air heat exchanger 4 is narrower than the upper side, a waterproof structure 20 for preventing liquid from seeping into the machine room side housing 2 from the air heat exchanger 4 through the through hole 10 provided between the machine room side housing 2 and the air heat exchanger 4 can be provided in conjunction with forming the air heat exchanger 4. Therefore, even in a heat source unit 1 equipped with an air heat exchanger 4 that is provided in an inclined state so that the lower side is narrow and the upper side is wider, it is easy to provide the waterproof structure 20.

[0043] Furthermore, according to the heat source unit 1, the waterproof structure 20 is box-shaped and surrounds the through-hole 10. According to this configuration example, the box-shaped waterproof structure 20 can cover the periphery and the upper part of the through-hole 10 without any gaps, making it easier to prevent water from flowing into the machine room-side housing 2 through the through-hole 10.

[0044] Furthermore, according to the heat source unit 1, the refrigerant pipes 11 are supported on the side surfaces of the waterproof structure 20. If a configuration were considered in which the refrigerant pipes 11 were supported on the upper surface of the waterproof structure 20, water would be more likely to flow downward along the refrigerant pipes 11, and therefore water would be more likely to seep into the waterproof structure 20 from the portion of the upper surface of the waterproof structure 20 that supports the refrigerant pipes 11.

[0045] According to the heat source unit 1 of the present disclosure, the refrigerant pipes 11 are supported at their horizontally extending portions, rather than vertically extending portions, on the side surfaces of the box-shaped waterproof structure 20. Therefore, even if water flows along the refrigerant pipes 11, the water drips from the refrigerant pipes 11 before entering the waterproof structure 20, making it easier to prevent water from entering the waterproof structure 20. Furthermore, because the refrigerant pipes 11 are disposed above the side surfaces 21Ab and 21Ba and at a certain height above the upper surface of the baffle plate 6, even if a large amount of water enters the air heat exchange chamber of the air heat exchanger 4, water can be prevented from entering the waterproof structure 20 and, ultimately, the machine room-side housing 2.

[0046] Furthermore, according to the heat source unit 1, a part of the waterproof structure 20, in this case the side part, is used to support the refrigerant pipes 11. Therefore, there is no need to provide new members or structures to support the refrigerant pipes 11, and an increase in the number of parts and a complicated structure can be suppressed.

[0047] Furthermore, in the heat source unit 1, the refrigerant pipes 11 are supported on the waterproof structure 20 by elastically deformable rubber supporters 30 and non-elastically deformable fixed clamps 31. According to this configuration example, the rubber supporters 30 can absorb vibrations, while the fixed clamps 31 can firmly support the refrigerant pipes 11. This prevents the refrigerant pipes 11 from shifting position or coming into contact with each other, for example, when transporting the heat source unit 1. It is preferable to position the rubber supporters 30 and the fixed clamps 31 as close as possible to each other.

[0048] Furthermore, according to the heat source unit 1, the waterproof structure 20 includes a sealing member 33 between the first waterproof structure forming part 21A and the second waterproof structure forming part 21B. This configuration example prevents a decrease in waterproofness between the multiple parts 21A and 21B, even when the waterproof structure 20 is formed by combining multiple parts 21A and 21B, thereby suppressing the effects of heat on the refrigerant pipe 11. The sealing member 33 may be made of a material that is not only waterproof but also has, for example, cushioning or insulating properties. This ensures shock absorption and insulation between the multiple parts 21A and 21B. Using a material that is particularly elastic, cushioning, and shock absorbing for the sealing member 33 facilitates assembly and reduces manufacturing variations.

[0049] Furthermore, according to the heat source unit 1, the waterproof structure 20 is configured such that the end of the cover member 22 that closes the open top portion of the main body 21 extends outward like a canopy beyond the main body 21. According to this configuration example, water that drips onto the cover member 22 can be guided outward beyond the main body 21, further preventing water from entering the waterproof structure 20.

[0050] It should be noted that this embodiment is not limited to the above-described embodiment, and various modifications and extensions can be made without departing from the spirit of the present invention.

[0051] Although the embodiments of the present invention have been described above, these embodiments are presented merely as examples and are not intended to limit the scope of the invention.
