JP 2012-097921 A

In the flow path forming member of Patent Literature 1, the partition plate is supported on the floor slab by support legs to maintain the distance between the partition plate and the surface panel. The support leg is configured such that two cylindrical members are nested together and the length thereof can be adjusted by sliding the two cylindrical members in the axial direction. The upper cylindrical member has an annular stop member attached to its upper end and an annular flange portion provided to its lower end.

The support leg has a flange portion in contact with the lower surface of the partition plate, and an upper end portion of the support leg is inserted into a recess formed on the back side of the surface panel, and the surface panel is in a state in which the stop member is in contact with the back surface of the surface layer panel. connected with Therefore, when a person walks on the floor and a load is applied to the floor material, the cylindrical members and flanges that form the support legs rub against the partition plate according to the deflection of the floor material, causing noise and noise. So-called floor rumbling (stomping noise) may occur.

SUMMARY OF THE INVENTION An object of the present invention is to prevent abnormal noise caused by installing a flow path forming member in a bosom space of a building.

In order to achieve the above object, in the present invention, a flow path forming member is fixed to a partitioning member that partitions a target space to be cooled or heated in a building.

Specifically, the first invention is directed to a flow path forming member. A flow path forming member according to a first aspect of the present invention forms a flow path for temperature-controlled conditioned air in a pocket space provided on the back side of a partition member that partitions a target space to be cooled or heated in a building. Form. The flow path forming member is arranged in the bosom space so as to face the partitioning member, and divides the bosom space into a downstream space positioned on the side of the partitioning member and an upstream space positioned on the side opposite to the partitioning member. a partition plate portion for partitioning, a blowout portion having a ventilation hole penetrating the partition plate portion and blowing out the temperature-controlled air introduced into the upstream space to the downstream space; and an attachment part that protrudes and is attached to the partition member.

In the first aspect of the invention, the flow path forming member includes the partition plate portion arranged in the bosom space so as to face the partition member. The partition plate partitions the bosom space into an upstream space and a downstream space. The flow path forming member further includes a blowout portion having a vent penetrating through the partition plate portion. The blowout part blows out the temperature-controlled air introduced into the upstream space to the downstream space. Conditioned air is temperature-conditioned air, cold or warm. Cold heat or warm heat of the temperature-controlled air flowing in the downstream space is transferred to the partitioning member.

If the temperature-controlled air is cold air, the partition member is cooled. Cold heat is radiated to the target space from the cooled partition member. As a result, the target space is cooled. Also, when the temperature-controlled air is warm, the partitioning member is warmed. Heat is radiated to the target space from the warmed partition member. As a result, the target space is heated. In this way, the target space can be cooled or heated by converting the energy of cold air or warm air into radiant heat through the partition member.

The flow path forming member has an attachment portion protruding from the partition plate portion toward the partition member, and is arranged in the bosom space by attaching the attachment portion to the partition member. As a result, the flow path forming member is fixed to the partition member without being directly connected to the support leg. Therefore, even if the partitioning member is bent due to the application of a load or the like, it is possible to prevent the flow path forming member and the supporting leg from rubbing against each other. Therefore, it is possible to prevent abnormal noise caused by installing the flow path forming member in the bosom space of the building.

A second invention is the flow path forming member according to the first invention, wherein the blow-out portion is composed only of the vent hole.

In the second aspect of the invention, the blowout portion is composed only of the air holes. The temperature-controlled air introduced into the upstream space is blown out into the downstream space from the ventilation holes toward the partition member. After hitting the partitioning member, the temperature-controlled air blown out from the ventilation hole spreads along the partitioning member and flows in the downstream space. According to this, cold heat or hot heat of the temperature-controlled air can be effectively transmitted to the partition member. In addition, since the flow path forming member has a simple structure, it can be installed even if the pocket space is narrow.

A third aspect of the invention is the flow path forming member according to the first aspect of the invention, wherein the blowout portion has a cylindrical portion projecting from the partition plate portion toward the partitioning member. One end of the cylindrical portion communicates with the air hole, and the other end of the cylindrical portion is formed with an outlet for blowing out the temperature-controlled air toward the partitioning member.

In the third aspect of the invention, the blowout portion has a cylindrical portion. The tubular portion protrudes from the partition plate portion toward the partitioning member, and blows out the temperature-controlled air that has flowed into the ventilation hole from the upstream space toward the partitioning member from the outlet. After hitting the partitioning member, the temperature-controlled air blown out from the outlet of the cylindrical portion spreads along the partitioning member and flows in the downstream space. According to this, the temperature-controlled air can be efficiently blown against the partitioning member, and the cold or hot heat of the temperature-controlled air can be effectively transmitted.

A fourth aspect of the invention is the flow path forming member according to the first aspect of the invention, wherein the blowout portion has a cylindrical portion projecting from the partition plate portion toward the partitioning member. One end of the cylindrical portion communicates with the vent hole, and when the partitioning member abuts on the other end of the cylindrical portion, the conditioned air is blown out in a direction along the partitioning member. A plurality of recesses are formed that form outlets with the partition member.

In the fourth aspect of the invention, the blowout portion has a cylindrical portion. The tubular portion protrudes from the partition plate portion toward the partitioning member, and blows out the temperature-controlled air that has flowed into the ventilation hole from the upstream space in the direction along the partitioning member from the outlet formed together with the partitioning member by the concave portion. As a result, the temperature-controlled air can be efficiently diffused in the downstream space. Therefore, cold heat or warm heat of the temperature-controlled air can be transmitted over a wide range of the partition member. This is advantageous in suppressing the occurrence of temperature nonuniformity in the partition members that radiate heat.

A fifth aspect of the present invention is the flow path forming member according to the fourth aspect, wherein an end portion of the cylindrical portion opposite to the air hole is provided with an abutment surface portion that abuts against the partitioning member. It is a forming member. An opening communicating with the cylindrical portion is formed in the abutment surface portion. The recess extends from the periphery of the opening to the outside in the radial direction of the tubular portion in a groove shape and is open to the outer peripheral side of the tubular portion.

In the fifth invention, the opening is formed in the abutment surface portion of the cylindrical portion. The recess extends radially outward of the cylindrical portion from the peripheral edge of the opening and is open to the outer peripheral side of the cylindrical portion. The temperature-controlled air that has flowed into the tubular portion from the upstream space through the ventilation hole flows through the opening to the outer peripheral side of the recess and is blown out from the outlet in a direction along the partitioning member. As a result, the directivity of the temperature-controlled air blown out from the outlet is enhanced. Thereby, the temperature-controlled air can be widely diffused in the downstream space.

A sixth invention is the flow path forming member according to the fifth invention, wherein the abutment surface portion is fixed to the partitioning member.

In the sixth invention, the abutment surface portion of the cylindrical portion is fixed to the partition member. This determines the relative positional relationship between the abutment surface portion of the tubular portion and the partition member. Therefore, it is possible to suppress variation in the flow path area of the temperature-controlled air formed between the recess and the partition member, and improve the dimensional accuracy of the outlet. This is advantageous for stabilizing the diffusivity of temperature controlled air in the downstream space.

A seventh invention is the flow path forming member according to any one of the fourth to sixth inventions, wherein a plurality of the blowout portions are provided. In the tubular portion adjacent to each other, the flow path forming member is set so that the opening directions of the outlets do not face each other.

In the seventh invention, the opening directions of the outlets are set so as not to face each other in the tubular portions adjacent to each other. According to this, it is possible to avoid collision between the temperature-controlled air blown out from the outlet of one tubular portion and the temperature-controlled air blown out from the outlet of the other tubular portion. Therefore, the temperature-controlled air blown from the outlet of each tubular portion reaches a relatively long distance. This is advantageous for widely diffusing temperature-controlled air in the downstream space.

An eighth invention is the flow path forming member according to any one of the first to seventh inventions, wherein the blow-out portion has a cylindrical portion protruding from the partition plate toward the partition member. It is a member. A plurality of blowout holes for blowing out the temperature-controlled air in a direction along the partitioning member is formed in the peripheral wall of the tubular portion.

In the eighth invention, a plurality of blowout holes are formed in the peripheral wall of the cylindrical portion. The blowout holes blow out the temperature-controlled air in a direction along the partitioning member. Such an aspect of the blowout section can also diffuse the temperature-controlled air in the downstream space, and can transfer the cold heat or heat of the temperature-controlled air over a wide range of the partition member.

A ninth invention is the flow path forming member according to the eighth invention, wherein a plurality of the blowout portions are provided. In the tubular portions adjacent to each other, the opening directions of the blowout holes are set so as not to face each other.

In the ninth invention, the opening directions of the blowout holes are set so as not to face each other in the tubular portions adjacent to each other. According to this, it is possible to avoid collision between the temperature-controlled air blown out from the blow-out hole of one tubular portion and the temperature-controlled air blown out from the blow-out hole of the other tubular portion. Therefore, the temperature-controlled air blown out from the blow-out hole of each cylindrical portion reaches a relatively long distance. This is advantageous for widely diffusing temperature-controlled air in the downstream space.

A tenth invention is directed to a cooling and heating system. A cooling and heating system according to a tenth aspect of the present invention comprises a partitioning member that partitions a target space to be cooled or heated in a building, and an air conditioner that draws in air from the target space and generates temperature-controlled air. and a passage forming member according to any one of the first to ninth inventions, which is installed in a bosom space provided on the back side of the dividing member. In the cooling and heating system, the temperature-controlled air generated by the air conditioner is introduced into the upstream space of the bosom space, blown out from the blowout portion of the flow path forming member into the downstream space, and the downstream space is discharged. After passing through, it is introduced into the target space.

In the tenth invention, the cooling/heating system includes an air conditioner that takes in air in the target space and generates temperature-controlled air. Then, the cooling and heating system introduces the temperature-controlled air generated by the air conditioner into the target space after sequentially passing through the upstream space and the downstream space partitioned by the flow path forming member in the bosom space. According to this, the temperature-controlled air introduced into the bosom space is temporarily stored in the upstream space, so that the temperature-controlled air can be spread evenly throughout the downstream space. As a result, cold heat or warm heat of the temperature-controlled air that is transmitted to the partition member can be made uniform. In addition, since the temperature-controlled air circulates through the passage of the bosom space and the target space, heat radiation from the partitioning member and convection by the temperature-controlled air allow highly comfortable cooling and heating of the target space.

As described above, according to the present invention, it is possible to prevent abnormal noise caused by installing the flow path forming member in the bosom space of the building.

－Operation of air-conditioning system－
The cooling and heating system 1 configured as described above introduces the temperature-controlled air generated by the air conditioner 10 into the upstream space US of the underfloor space SP, and blows it out from the blowout portions 62 of the plurality of flow path forming members 60 into the downstream space DS. , into the target space TS after passing through the downstream space DS. In the cooling/heating system 1, the user can instruct the air conditioner 10 to perform cooling operation or heating operation by operating a remote controller (not shown).

When the air conditioner 10 performs a cooling operation, the indoor unit 11 draws air from the target space TS and generates cold air as temperature-controlled air. Cool air generated by the indoor unit 11 is sent to the duct box 32 through the duct pipe 31 and introduced from the duct box 32 into the underfloor space SP. The cold air introduced into the underfloor space SP accumulates so as to spread over the entire upstream space US. Then, when the pressure in the upstream space US increases relatively, the cool air accumulated in the upstream space US is discharged from the outlet 68 formed by the outlet 62 of the flow path forming member 60 and the floor panel 40 to the lower surface of the floor panel 40. is blown out into the downstream space DS. Cold heat of the cold air blown into the downstream space DS is transferred to the floor panel 40 . Therefore, when the floor panel 40 is cooled, cold heat from the floor panel 40 is radiated to the target space TS. The cool air flows through the downstream space DS toward the return section 90 and is returned to the target space TS via the return section 90 . This cools the air in the target space TS.

In addition, when the air conditioner 10 performs heating operation, the indoor unit 11 draws air from the target space TS and generates warm air as temperature-controlled air. Warm air generated by the indoor unit 11 is sent to the duct box 32 through the duct pipe 31 and introduced from the duct box 32 into the underfloor space SP. The warm air introduced into the underfloor space SP accumulates over the entire upstream space US. Then, when the pressure in the upstream space US increases relatively, warm air accumulated in the upstream space US is discharged from the lower surface of the floor panel 40 from the outlet 68 formed by the outlet 62 of the flow path forming member 60 and the floor panel 40 . is blown out into the downstream space UD along the . The heat of the warm air blown out to the downstream space DS is transferred to the floor panel 40 . As a result, when the floor panel 40 is warmed, the heat from the floor panel 40 is radiated to the target space TS. The warm air flows through the downstream space DS toward the reflux portion 90 and is returned to the target space TS via the reflux portion 90 . This heats the air in the target space TS.

-Installation method for floor panels and channel-forming members-
In order to construct the floor panel 40 and the flow path forming member 60 of the cooling/heating system 1, first, the blowout portions 62 of the flow path forming member 60 corresponding to the size of the base panel 41 are formed on the back surface of the base panel 41. Install. At this time, the abutting surface portion 65 and the mounting portion 70 of each flow path forming member 60 are fixed to the base panel 41 with screws. Then, the joining tape 77 is attached to the rear surfaces of the flow path forming members 60 adjacent to each other so as to cover the seams formed by the long sides of the two members 60 . Further, the end portion receiving member 80 is fixed to the end surface of the flow path forming member 60 located at the outer peripheral portion of the heat transfer bed 45 by screwing or the like. Then, as shown in FIG. 11, the heat transfer floor panel 100 (illustration of the end fitting member 80 is omitted in FIG. 11) in which the flow path forming member 60 and the base panel 41 are combined is placed in the target space TS. Prepare as many as you need to fit your floor space.

Next, a plurality of support legs 50, edge joists 55 and channel partitioning members 81, 82 with cushioning material 83 are installed on the floor slab FS. Then, the heat transfer floor panel 100 is supported by the support legs 50 and the border member 42 is supported by the support leg 50 and the edge joists 55, and the base panel 41 and the border member 42 are laid. Subsequently, the adhesive material 43 is laid on the base panel 41 and the border material 42 . Further, a floor finishing material 44 is pasted on the waste pasting material 43 .

As described above, the floor panel 40 and the flow path forming member 60 can be constructed on the floor of the target space TS.

- Features of the embodiment -
The flow path forming member 60 of this embodiment includes a partition plate portion 61 arranged in the underfloor space SP so as to face the floor panel 40 . The partition plate portion 61 partitions the underfloor space SP into an upstream space US and a downstream space DS. The flow path forming member 60 further includes a blowout portion 62 having a vent hole 63 passing through the partition plate portion 61 . The blowout part 62 blows out the temperature-controlled air introduced into the upstream space US to the downstream space DS. If the temperature-controlled air is cool, the floor panel 40 is cooled. Cold heat is radiated to the target space TS from the cooled floor panel 40 . Thereby, cooling of the target space TS is performed. Also, if the temperature-controlled air is warm, the floor panel 40 is warmed. Heat is radiated to the target space TS from the heated floor panel 40 . Thereby, heating of the target space TS is performed. In this way, the energy of cold air or warm air is converted into radiant heat through the floor panel 40, so that the target space TS can be cooled and heated.

The flow path forming member 60 of this embodiment includes an attachment portion 70 projecting from the partition plate portion 61 toward the floor panel 40 , and is arranged in the underfloor space SP by attaching the attachment portion 70 to the floor panel 40 . As a result, the flow path forming member 60 is fixed to the floor panel 40 without being directly connected to the support leg 50 . Therefore, even if the floor panel 40 is bent due to the load applied when a person walks on the floor, the flow path forming member 60 and the support leg 50 can be prevented from rubbing against each other. Therefore, it is possible to prevent abnormal noise caused by installing the flow path forming member 60 in the underfloor space SP of the building BD.

In the flow path forming member 60 of this embodiment, the blowout portion 62 has a tubular portion 64 . The tubular portion 64 protrudes from the partition plate portion 61 toward the floor panel 40 and directs the temperature-controlled air that has flowed into the ventilation hole 63 from the upstream space US to the floor by a concave portion 67 provided in the abutment surface portion 65 of the tubular portion 64 . The air is blown out in the direction along the floor panel 40 from the outlet 68 formed together with the panel 40 . As a result, the temperature-controlled air can be efficiently diffused in the downstream space DS. Therefore, cold heat or warm heat of the temperature-controlled air can be transmitted over a wide area of the floor panel 40 . This is advantageous in suppressing temperature unevenness in the floor panel 40 that radiates heat.

In the channel forming member 60 of this embodiment, an opening 66 is formed in the abutment surface portion 65 of the tubular portion 64 . The recessed portion 67 extends outward in the radial direction of the cylindrical portion 64 from the peripheral edge of the opening 66 in a groove shape and is open to the outer peripheral side of the cylindrical portion 64 . The temperature-controlled air that has flowed from the upstream space US through the ventilation hole 63 into the cylindrical portion 64 flows through the opening 66 to the outer peripheral side of the recess 67 and is blown out from the blowout port 68 in the direction along the floor panel 40 . As a result, the directivity of the temperature-controlled air blown from the outlet 68 is enhanced. Thereby, the temperature-controlled air can be widely diffused in the downstream space DS.

In the channel forming member 60 of this embodiment, the abutment surface portion 65 of the tubular portion 64 is fixed to the floor panel 40 . This determines the relative positional relationship between the abutment surface portion 65 of the tubular portion 64 and the floor panel 40 . Therefore, it is possible to suppress variation in the flow path area of the temperature-controlled air formed between the recessed portion 67 provided in the abutment surface portion 65 and the floor panel 40 , and increase the dimensional accuracy of the air outlet 68 . This is advantageous for uniforming the diffusivity of temperature-controlled air in the downstream space DS.

In the flow path forming member 60 of this embodiment, the opening directions of the outlets 68 of the adjacent tubular portions 64 are set so as not to face each other. According to this, it is possible to avoid collision between the temperature-controlled air blown out from the outlet 68 of one tubular portion 64 and the temperature-controlled air blown out from the outlet 68 of the other tubular portion 64 . Therefore, the temperature-controlled air blown from the outlet 68 of each cylindrical portion 64 reaches a relatively long distance. This is advantageous for widely diffusing the temperature-controlled air in the downstream space DS.

The cooling/heating system 1 of this embodiment includes an air conditioner 10 that draws in air from a target space TS to generate temperature-controlled air. Then, the cooling and heating system 1 causes the temperature-controlled air generated by the air conditioner 10 to pass through the upstream space US and the downstream space DS partitioned by the flow path forming member 60 in the underfloor space SP in this order, and then passes through the target space. Introduce to TS. According to this, the temperature-controlled air introduced into the underfloor space SP is temporarily stored in the upstream space US, so that the temperature-controlled air can be distributed evenly throughout the downstream space DS. Thereby, the cooling or heating of the temperature-controlled air transmitted to the floor panel 40 can be made uniform. In addition, since the temperature-controlled air circulates through the flow path of the underfloor space SP and the target space TS, thermal radiation from the floor panel 40 and convection due to the temperature-controlled air can perform highly comfortable cooling and heating of the target space TS.
